Safety Quest 2022

We conducted our annual Safety Quest on 18 Nov 2022. It was heartening to see 190 students participating wholeheartedly.
For those of you who would like to try the quiz at your own pace, you can visit: https://kahoot.it/challenge/008080101

Safety Champions2We shared examples of a few young children, 10-16 years of age, who have demonstrated creative thinking in designing innovative solutions for safety, and some who have shown exceptional leadership to guide others to safety. We hope it inspires our young participants, and they also realise that they can make a difference.

While the questions were not very difficult, behind each question was some lesson or information that would have given the children better insight into the techniques, science or innovations.

Way back in 1854 John Snow carried out a neat data analytics exercise when he mapped the deaths due to cholera on the map of London, and then further added the position of the water pumps. The correlation jumps out visually to the reader, and draws a strong cause-effect relationship to the contamination of the water from a specific water pump. We included this example to help children understand the power of using data in scientific analysis.

It is heartening that the children know many answers. This builds hope that the future generation may strive to improve safety on the roads, or otherwise. They were well aware of
• distracted driving, the protection provided by helmets, and hand signals
• first aid techniques like Heimlich maneuver and CPR – the videos would have given them details about the techniques
• the effects of climate change
• the different types of fire extinguishers

There were a few questions where the scores were low, and the Safety Quest may have given some exposure to the children:
• Stop Drop and Roll : the technique used when one’s clothes are on fire
• Stubble burning : a major health hazard in the NCR region
• Cone of Vision : How it narrows as the speed of the vehicle increases
• Cybersafety : Guarding with strong passwords, and recognizing phishing
• Safely charging electronic vehicles

We hope they continue to remember these as they become adults and take on greater responsibilities.

Some children were forthcoming in sharing :

  • Jyotsna V Vadivel shared how the students of her school were affected when a fellow student lost his life in a fatal crash due to the rash driving of a bus driver. The whole school lit candles in his honour.
  • Vishnu Siddhartha K was very well aware of Cybersafety, and suggested that to recognize phishing attacks, we should check for spelling errors, unauthorised identities, and check that it relates to to our online activity

The Winners
The Quiz platform rewards correct answers and also the speed with which they are given. It was a close contest, and the winners of our quiz were

  1. Aditya Rajiv Ratnam
  2. Vishnu Sriguruganesh
  3. Sooryanshi
  4. Iniyaa Elaiyaraja
  5. Shuban Singh

Road Safety in Goa

Oct 21: Open Forum

We attended an Open Forum for Road Safety Management which was initiated by the Chief Minister, with the Minister for Transport, the PWD minister, and the government officials. They had invited the public to provide suggestions to improve the safety on our roads. It was heartening to see so many people who felt strongly about the cause. And they presented fairly detailed write ups on specific points for improvement.

openforuminvitation   openforum_3

The CM has promised the public that the inputs will be analysed and an action plan will be shared within 15 days, and implementation will begin as early as Dec 1. It’s a good start to the process.

We also provided our inputs:

  • Goa has better roads than most other places. People from Goa may disagree, but having seen roads elsewhere, I can confidently say this. This also means the average speed in Goa is higher! Hence the impact of any crash will likely be higher. It will be better if Goa adopts a policy and traffic calming measures to curtail maximum speed.
  • Goa is undoubtedly the most popular destination for tourists. The holiday partying and access to alcohol means there is every chance that some drivers are not in full control of their senses or reflexes. Creative ideas should help enforce discipline without affecting tourism. In fact, it should enhance the reputation of Goa as a safe destination.
  • Apart from this, an emphasis on building superb public transport, inculcating right safety mindset through school curriculum, and an immediate focus on black spots was urged. Of course, we have to address some immediate issues, but as we do it, we recommend a holistic safe systems approach for a sustainable solution.

The event recording is available here

Thanks to our friend and a passionate advocate for road safety – Sanjeev Sardessai – who invited us to this event.

Nov 5: Road Safety at IMS Goa

ims_2We conducted a road safety session for the students and staff of the Institute of Maritime Studies (IMS), Goa.     The attendance was over a 100 people, a majority of them young students who will soon take on the mantle for their families. Interestingly, the motto of IMS is “Suraksha Siddha Haste” meaning Security in Competent Hands! And the students had created several posters related to Safety in their workshops. And the focus of our talk is also the Tenets of Proactive Driving so that with competency, alertness, awareness, and anticipation we continue to enjoy the ride.

ims_1

At least 10 people in the audience had been involved in a road accident.  The discussion on blind spots was an eye-opener (pun intended!) for most. The small exercise to bust the myth of multitasking was very well received. It was wonderful to have the 100 people stand up and take the Road Safety Pledge in unison.

After the session, Francis came up to us and said that it shook him, and he promised to implement it seriously and to take the message to his family. Tanuj pointed out other violations – like the people who encourage children to stand up with their heads poking out of the sun roof. One observation is that many of the two wheelers tend to overtake from the left side of the vehicle ahead – this seems to be quite prevalent in Goa. They are probably ignorant about blind spots. This should be a very important part of the training. Ajay pointed out the higher average speeds in Goa due to better roads and therefore the need to curb speed.

A special “Thank You” goes out to Director Dipak Shah, and Deputy Director Ajay Tambwekar who organised the event.

Nov 5 : Distraction of a different kind

On the way back from the session at IMS, we reached the Zuari bridge. rearhitHere, the two broad lanes narrow down to one small lane as the vehicles cross the old bridge over the Zuari river. So there is a bottleneck for a short stretch where the traffic is choked, moving slower in stops and starts. At one point, when we stopped, we were suddenly hit from behind by a car.

We pulled over and so did the driver behind. After checking that there was no damage to any person, we asked the driver what happened.

He said he had placed his phone on the passenger seat, and suddenly it fell down. He immediately reached down to pull up the phone. It was the moment when he took his eyes, his hands and his mind had all focused on a task other than driving, and he did not realise that he had to stop. He rear-ended our car!

Two things stand out for me:

  1. The attraction for a cellphone is overpowering and that lead to the distraction. Even if we are not using it, we feel the need to have the cellphone accessible at all times. It would have been easy to wait till he got to a safe spot and then retrieved the phone, but the pull of the cellphone was very strong!
  2. We often underestimate the risk associated with such actions. We believe we are very capable of controlling the vehicle when doing such tasks on the side. But a split second is enough to cause the damage. In the big picture, the time lost in stopping and addressing such a task would be trivial, so err on the side of caution and do not drive distracted. In fact, in a stop-start traffic, there has to be extra alertness.

Luckily for both of us, the speed was curtailed by the bottleneck. Imagine if this had happened on the highway at 70-80 kmph!

Even at this slow speed, the impact was such that we were thrown forward in our seats. The seat belts helped us, else our heads would have hit the steering / dashboard for sure.

The incident made we wonder why it happened to us on our way back from a road safety session. Imagine the roads 10, 20 years from now. How many vehicles will there be on the roads? What kind of driver behaviour will we see? What will be the speeds, the road conditions? Clearly, there is a lot that has to be done to make our roads safer!

From “I Feel It’s Safe” to “Topsy Turvy” In A Split Second!

When it comes to road safety, the risks are often conveyed in terms of statistics. Yet, despite losing over 400 people every day on Indian roads, our road users seem to judge risk quite differently. We tend to minimize personal risk due to unrealistic optimism and an over-estimation of our driving abilities, leading to perceived invulnerability. But things can turn topsy turvy in a split second!

I Feel It’s Safe!

Take a look at the pics below. Each depicts a risky behaviour.  Overspeeding, overtaking on a curve at high speed, jumping lights, intentionally driving on the wrong side, is particularly aggressive risk taking. But the persons involved believe they are in complete control.

risk_p6

Risk_p3

risk_p4

risk_p9

risk_p5

risk_p7

There can be internal factors affecting the driver behaviour: experience and past memory, stress, fatigue, mood. And there can be external factors as well: the road condition and signage, the environment, the group who is with the driver. These factors can lead to a failure to examine risks, poor information gathering, bias in processing information, and therefore risk perception.

The person rationalizes, and justifies the behaviour to himself – he is attending to an urgent matter, it was an important phone call, because ‘everyone is doing it’. Some people may not even realise that what they are doing is risky – it is just normal for them. People have been used to riding without helmets, so the risk perception does not change with the law. And everyone around uses the mobile phone! Sometimes it is to impress peers, although they may not admit it. Thrill seekers knowingly take high risks. Overindulgent parents who encourage children to stand up in the cars, or encourage minors to get into the driver’s seat, believe that their behaviour was safe.

This is not limited to people in the driver’s seat.

risk_pedestrianYou can see in the pic, a pedestrian is taking some risk with the distracted walking.  He has probably done it many times before.

Pedestrians do have a tough time on our roads because the sidewalks are encroached, or the facilities to cross the roads are non-existent. This leads to undue risk especially when crossing broad and busy thoroughfares.

 

 

risk_mistry

The unfortunate crash that led to the demise of Mr. Cyrus Mistry brought into sharp focus the use of seatbelts in the rear seats. How often do you see people in rear seats wearing seatbelts? It is a rarity. Mr. Mistry may have been accustomed to travel in this manner, and may have covered thousands of km in the rear seat.

 

 

risk_busOr take the example of the tragic bus crash near Tumkur in Karnataka. Was it the first time that the people were travelling in the overcrowded bus? Was it the first time that the driver has packed so many passengers in his bus? Most certainly not. The passengers rationalise that they have no other means. The driver and the transport company are keen to make the most of the opportunity for their gains, they are confident of their vehicle and their ability to control it. They can all justify the reason for their action. Plus, they had made the trip numerous times. So why not one more time?

 

Topsy Turvy In A Split Second

If the first risky attempt results in some injury or a near miss, the person may refrain from such behaviour. But more often than not, this passage is without any hiccups. And then, the behaviour repeats, many times over, to a point when the person has an exaggerated sense of control.

It will take just one fall to the ground from the motorbike to damage the skull. It will be just one instance of a speedy ride spinning out of control. It will be just one instance of the underage driver panicking.  Whether in the case of the bus tragedy, or in the case of Mr. Mistry, on the fateful day, it was a split second that turned everything topsy turvy!

And when the moment arrives, it is too late to take evasive action or to make any correction. Extra caution is required to curb the optimism bias, for things can turn topsy turvy in a split second!

Risk Perception and Tolerance

Risk perception is the ability to discern risk, and risk tolerance is the capacity to accept a certain amount of risk ( we often use the term “calculated risk” ).

There is an interesting correlation with the age of the driver. Younger drivers are overconfident because they underestimate the hazard or do not anticipate it. This is due to inexperience. On the contrary, the experienced drivers underestimate the risks because some of them are familiar! Or, as discussed earlier, the repeated experience blunts the sense of risk and exaggerates the sense of control.

It is known that men take more risks on the road compared to women drivers. This is primarily because the risk tolerance levels of women are lower, and there is a strong correlation to the family affiliation.  Thrill seekers have a very high risk tolerance, and they knowingly engage in extremely risky behaviour.

What Can We Do About It?

We need safer systems – safer roads, safer vehicles, safer speeds – that will be more forgiving to human errors. But there is no substitute to a safety mindset – safety is not by accident.  As my friend Naresh Raghavan ( the author of the Card Driving School Manual for India ; he has recently released his course online for free Indian Driving Rules (Professional Road Safety Course) – YouTube ) says “Driving may be fun. But primarily it is a huge responsibility. A well-trained driver can drive safely through bad roads, bad traffic conditions, bad weather. Good driving is science, don’t leave it to luck”.

The awareness that the road is a shared space, and that we all should be able to continue to enjoy our driving or walking is essential to reduce risky behaviour. Perception of risk is a critical antecedent to at-risk road behaviour. Conventional defensive driver training should be augmented with training to increase self-awareness so as to improve technical driving skills without increasing overconfidence.  We suggest the use of toolkits with a set of questions supplemented by videos and images. The drivers can do a self-assessment. Based on the answers, there can be a targeted sensitization. This will help temper their risk perception. The toolkit can also help draw a stronger connection to family and community so that they feel the need to avoid the negative consequences and thus lower their risk tolerance. Fleets ( trucks, buses, taxis ) should certainly implement this on a regular basis.

“Catch them young!” – The sooner we do this in the life of a driver, the better it is.  This can be incorporated into the process to grant a driving license, and then at each renewal to help the driver re-calibrate.

If you have any suggestions, I would love to hear from you!

Vishing and Smishing

In our last post, we analysed the clickbait in phishing emails. In this article, we look at the 2nd part of cyber safety, Vishing and Smishing.

Vishing is voice phishing, the tactics that lead to sensitive information being obtained via phone calls. And Smishing is short for SMS phishing, when an ordinary looking SMS has a hook that snares the victim and leads him to share sensitive information. The prevalence of this phenomenon led to the creation of the series Jamtara – Sabka Number Aayega which dramatised some true stories.

Often, the fraudster poses as a person with some authority – from the bank, from the government, from the police, from the workplace, etc. – and the victim is convinced that it is right to share the information. People may be wary of another person calling with such authority, but there are other occasions where greed or fear lead to an error. Let us see some examples.

Vishing – Case 1
Mani put up a car for sale on an online website. He posted a few nice pictures of his car along with the expected sale price, and his phone number. Later in the day, he got a call. vishing1
“This is Colonel Rajendran. I am a ex- army officer, now in civil service after 18 years in the army. As an army man, I like dealing with honest people, so I am happy that you have posted about the small accident you had. I am keen to purchase it”.
Mani was very happy. He asked the Colonel to come over and check out the car.
The Colonel said, “For sure, I will do so. But I want to reserve the car. Hence, I want to pay you a token amount up front. I will transfer Rs 50,000.”
On the Colonel’s request, Mani shared the bank details to transfer the money.
vishing_qrWhile still on the call, the Colonel transferred Rs. 100 to Mani. “It was a trial transaction. I will now transfer the Rs 50,000”, he said, keeping Mani engaged on the call. A little later, he told Mani, “Since the amount is a bit high, the bank wants me to share a QR code for your authorization. I will share it on your email, and you can scan it with your banking app”.
Mani shared his email, and in a moment, he received the QR Code via an email that from col_rajendrann. Following the Colonel’s instructions, Mani opened his usual mobile banking app, and scanned the QR code. “I am approving it”, he told the Colonel. As soon as he had approved it, the phone got disconnected. Mani then noticed an SMS that his account had been deducted for Rs 50,000.

Note the modus operandi of the fraudster. He builds trust posing as an ex-army officer, and appealing to Mani’s honesty. And he keeps Mani distracted with his conversation while he sends the QR code. What did Mani miss? If you have paid using QR code in shops, you will realise that it identifies the entity receiving the money, and may embed the amount in it as well. The QR code is scanned by the person who pays, and not by the person who receives the money! This small detail would have alerted Mani.

Vishing – Case 2

Payal got a call in the afternoon. “Hi, this is Surya from xxxx.com. Am I speaking to Payal Sharma?”.vishing2 Payal confirmed. Surya’s voice was very enthusiastic, ”We recently held a lucky draw for our regular customers. I am happy to say you are one of the lucky winners! One amongst 10 lac! The prize is a gift coupon worth Rs 20,000! Congratulations!” Payal was very excited. She had never been so lucky before. Surya said, “I need to verify a few details to ensure that we are indeed sending it to the right Payal Sharma. Can you confirm your first name, last name, and your address?”. Payal did so.

Surya then said, “Our database says that you have used a Credit Card for your purchases. Can yovishing2_picu confirm the card details? Your card number, expiry and CVV should match our records”. Payal went ahead and shared that as well.
Surya said, “Thank you for your patience. All the details have verified OK. I am now going to initiate the process for the dispatch of the gift card. You will receive an OTP, once you confirm the same, the delivery will be completed.”
The next second, Payal received an OTP. She opened it, her eyes registered Rs 20,000 and xxxx.com. She read out the OTP.
Surya said, “Thank you. The gift card is on its way!” and cut the call.
Immediately after that, Payal noticed that her account had been debited by Rs. 20,000.

Note the modus operandi. The fraudster has dangled the carrot of a free voucher, appealing to the basic greed. Again, the fraudster is keeping her distracted, and creating a sense of urgency to share the OTP. In the process, Payal does not pay full attention to the OTP.
Here is a typical OTP one may receive for transactions:

vishing_otp
Note the specific mention that it is for a transaction, i.e. a Purchase! And that the purchase is on MMM merchant. Also, it explicitly ask the user not to share the OTP.

Smishing – Case 1
It was the month of March. There had been many reminders requesting PAN number to be linked with Aadhar. In the last week of March, Dinesh received an SMS
smishing_kyc
Dinesh was alert. He recognized this as a Smishing attempt. What did he see?smishing1
He checked that the SMS was sent from phone number 079854xxxxx. A bank will never send messages from a personal phone number. By regulation, such messages have to be sent using a registered identity so you will see the receiver being VM-AxisBk or AD-SBI, etc.
He noticed that the language was not refined and it had errors. Most importantly, Dinesh was sure that the bank will never solicit such KYC information on its own. KYC does not get “suspended”. He ignored the SMS as a fraud message and carried on.

Smishing – Case 2
In the same period, Paul got a SMS :

smishing_block

Paul was cautious, but curious. He called the customer care number listed. He heard the usual recorded message that AAA Bank played. Then the agent picked it up. “Hi, thank you for calling AAA Bank. This is Sunita. How may I help you?” When Paul asked about the message he had received, Sunita told him “Let me check.”, and after a pause, she said, “This is quite common, so the bank has created an app to help customers. I will share a link with you. You can download the program and do the KYC details yourself”. The call ended, and Paul received a link on his mobile.  smishing2

At this time, Paul became suspicious, and decided to do a further check. The SMS had come from phone number 63834xxxxx, so not a genuine message from the bank. Wisely, he chose not to click on the link.

This is an example of a clever attempt (and a 2-step mechanism) to get victims to download malware onto their devices. The malware can then capture lot of sensitive information, and relay back to the fraudster.

Higher level of Security with 2FA and MFA
The two-factor authentication (2FA) in India provides a second line of defence even when certain sensitive information is compromised. 2FA brings two elements together:
mfa* Something you know : eg. Password, PIN, Credit Card details, etc
* Something you have : a mobile device where the OTP gets delivered; a chip card in your hand

Thus, even if card details etc are shared, unless the transaction OTP is shared, the authorization is incomplete.

 

Stronger authentication mechanisms include “something you are” e.g. biometric, so no one else can impersonate you.  Other factors include Location and Time.
Multifactor authentication (MFA) uses 2 or more factors to further strengthen the security.

Be(a)ware!
There are many other examples – impersonating your friend, fake job portals, fake tech support, fake covid testing / vaccination sites, fake loans, fake insurance offers – the list of fraudsters is long. But luckily, we have a short list of precautions!
Whether it is phishing, vishing, or smishing, remember that
* The fraudsters will play on your psychology – greed, or fear
* They will speak with authority, with practised ease that wins your confidence, and create a sense of urgency
* They will entice you to share the 2nd element of the 2FA – the OTP – that will complete the transaction.

Remember
caution* Scan a QR code only when you want to pay a merchant
* Check the OTP message to confirm it is triggered by your action for purchase or registration. Do not share any OTP
* If in doubt, check directly with your bank or the said authority
* Set your transaction limits to contain the loss in case of any such event

 

* In an unfortunate event, if you face such a situation, report it to the nearest Cyber Crime Police Station and National Cyber Crime Reporting portal at https://cybercrime.gov.in

Helmet_QuestionMark

Helmet : To Wear or Not To Wear

helmet_farokh 

“In cricket, batsmen started using box guards from about 1878, but the helmets came on the scene only in 1978”, Farokh Engineer, India’s dashing wicketkeeper-batsman once joked. “It took us 100 years to realise that we need to protect the upper storey!”

Many people object to the use of helmets citing different reasons: they are cumbersome to carry, they strain the neck, they mess up the hair. They also feel that for short distances or intra-city commute, the helmet is not required. They do not want the law to force them to wear a helmet, it can be a choice.

Data published by the Transport Research Wing of the Government of India [1] shows that a whopping 37% of the fatalities on our roads – and we lose over 400 a day – were 2-wheeler riders, of which almost 30% were not using helmets.

helmet_graph

2-wheeler riders (drivers and pillion) are the most vulnerable because there is no protection around the motorcycle, and since it does not have the stability of a 4-wheeler, it can be thrown off-balance.

So let us take the help of some physics and some anatomy to understand what happens in a crash and how the helmet makes a difference.

Whether one is driving, or in a crash, the law of physics will apply [2][3][4].  Following Newton’s first law of motion, when the motorcycle’s motion is halted, the rider will continue to travel forward (after being thrown off) at the same speed until stopped by another object or the road.  A head-on collision or a T-collision can lead to more severe injuries at high speed. But even at low speed, there is a risk of injury.

helmet_road2

This is because of the vertical movement as the rider falls to the ground, and may hit the head on the side, the forehead, the back, the chin. This vertical movement is the same whether the whether the crash occurs at 20 kmph or at 60 kmph.  And so, the vertical component of the velocity will be roughly the same at the time of impact. The potential energy from the seated position is now converted to kinetic energy. An average adult head weighs about 5 kg. Considering a height of 4.5 to 5.5 feet above the ground, the energy will be about 66 – 80 J, and the head will hit the ground at 19-21 kmph!  Studies have shown that the human skull can crack if the impact energy is 14 – 65 J depending on the point of impact [5].

When the rider hits the ground, there is a sudden deceleration. The change in velocity is instantaneous: from 20 kmph down to 0 in a fraction of a millisecond. All the kinetic energy due to the motion is now dissipated instantly, resulting in injuries to the rider.

What does the helmet do?

helmet_schematic

 

The helmet shell prevents any pointed objects penetrating. It also protects the rider from the lacerations due to friction as the horizontal movement comes to a halt.

 

Part of the crash energy is dissipated by the outer shell. This breaks the bonds in the material, and the shell is broken or deformed. The shell also spreads the impact over a broader area. All of which helps protect the head from damage.

 

helmet_csfThere is more. Our brain sits inside our skull, suspended in the cerebro-spinal fluid, encapsulated by a thin layer of duramater [7].  In a crash, the outer shell comes to a halt the moment it hits the ground. But the head continues to travel and will hit the helmet inside. The brain is violently shifted inside and will hit the inner wall of the skull. This can lead to concussion. The angle of impact will determine whether the brain moves to-and-fro or also goes through some twisting, stretching movements. This can lead to damage to the brain cells, affecting cognition, memory, concentration.

This is where the layer of foam – the impact-absorbing liner – comes into play.

The laws of Physics [2][3][4] tell us that the force acting on the skull / brain will be related to the change in the velocity, and the time over which this change occurs.

F = m (Δv) /Δt

We cannot control the mass. The change in velocity is also roughly fixed: 20 kmph, instantaneously.  Therefore, to reduce the force, we must slow down the process to extend the time over which the head meets the helmet. The layer of foam has a “give” and since it gets compressed, it increases the time over about 6 to 10 msec. These pictures from lab tests [8] will give you an idea of the way foam slows down the change of velocity, and thus reduces the force of the impact.

helmet_labtests

helmet_damaged

 

The foam used in the liner can absorb a lot of energy. In the process, the foam itself gets crushed, and stays that way. If it were to rebound, the head would be tossed once again!

As you can see in the picture, the helmet itself takes a solid beating while it protects the head. Hence, we discard helmets that have been in a crash.

There is constant endeavour to improve helmets and rider safety using newer materials that are tougher but lighter, adding layers to the liner, arranging the internal structure to distribute the impact over an even greater area. And while improving safety, there is a simultaneous attempt to make it more comfortable with the padding and the ventilation.

There is a saying in Hindi : “sir salaamat toh pagadi pachaas!” which means that if the head is in good health, one can play many different roles with ease – in the family, in the professional circles, in the community.

So, strap on your helmet snugly whether you are riding in the driver’s seat or pillion. But may it never come into play! Ride Safely!

PS : Young students who are interested, can do an egg drop experiment to understand the effect of foam; and a melon drop test to understand the overall effect of the helmet. Ask your teachers!

Safety Quest 2021

This year, we conducted the Safety Quest online on the 13th of November. The poster above was used for the invitation along with an FAQ. Thanks to our partners, Walnut Knowledge Solutions, and several well-wishers, the word spread across the country and also beyond. We had students in grades 6-8 from over 70+ cities from India and UAE. The major cities being Bangalore, Chennai, Kolkata, New Delhi, Mumbai, Hyderabad, Patna, Chandigarh, and AbuDhabi, Dubai, Doha.

We had a total of 1234 registrations of which 350 participants joined in for the event.
For those of you who wish to experience the quiz, check this out https://kahoot.it/challenge/003952769

As usual we strive to bring awareness to the students in a fun way. This time we leveraged the Kahoot platform more effectively, and it allowed us to create questions in different formats :
1) Multiple choice questions – where there may be 1 correct answer, or multiple correct answers
2) Type your answer – we made it a one-word answer, and allowed for typing mistakes
3) Arrange the options in order – where the 4 options could be moved around to create the sequence
Another good feature of Kahoot is that it logs the time to answer, and thus there is an automated method of ranking the correct answers based on “fastest finger first”.
The gamification also ensures that each participant sees the top performers on the charts, and their individual position vis-a-vis the leaders. This was also useful in engaging and enthusing the participants.

Students learnt about various aspects of safety : Road, Electrical, Fire, Cyber, Health, Environment
They learnt about techniques : Distress Signals, CPR, Creating a Floatation Device, Using a Fire Extinguisher
We included questions on innovative ideas from young children to inspire the participants, to let them know that they can make a difference.
We used videos to reinforce the learning.

At the end of the quiz, we asked the children to answer in one word “What is the 1 new thing that they learnt today?”. This is what the children responded with :

The worthy winners of the quiz were Ritwik Choudhary, Saaliha Bilal, Sanath Kothari, Gia Goel, Aditya Rajiv Ratnam
and Vidisha Swaika. Congratulations to all the winners!

Here is some feedback we received, which we thought was very heartening :

Since many of the registered participants could not join us, we shared the link to the quiz https://kahoot.it/challenge/003952769
This has also been shared with the teachers who had helped us mobilize the students for the quiz. So far, 177 people played the quiz shared in this manner! We hope that anyone who comes across this blog post will do so as well.

A big shout out to Anagha Sridhar, Shrija Bhattacharya, N Shilpa of Walnut Knowledge Solutions. They played a big role in putting together the content for the quiz. And during the event, despite some technical glitches, they kept the show going, keeping the audience engaged all through!

We are grateful to Lakshmi Nair, and Underwriters Laboratories, who came forward to sponsor the prizes for the event. One of the core values of UL is that of safety science, and therefore we are especially pleased to have UL as a partner for SafetyQuest since 2017. A sincere Thank You!

Safety Quest at Shiv Shikshan Sanstha’s Global School, Sion

9 Jan 2021 : We hosted the first Safety Quest of 2021 online for the young students of grades 3,4,5 of the Shiv Shikshan Sanstha’s Global School, Sion.

For many of them, it was the first time to attend such an event online, and some of them also faced operational challenges. Despite this, the children were enthusiastic and engaged all through the event.

Congratulations to the Top5 winners ! Aditya Kadam, Shreedatta Patil , Arush, Aishwarya Prakash Vhatkar and Aarya Helkar will receive their QShala vouchers. We are sure it will be a great learning experience for them.

The children wrote back to share what they retained :

  • Wear a helmet on scooters, and in the car put on the seat belt even in the rear seats
  • We are aware of safety – to protect self and others
  • It was enjoyable for students to learn safety in this manner

Here is the testimonial from the school management(Mrs. Sunita Pant – Principal):

“It was a wonderful event and was very engaging. Most of the parents called me personally and appreciated the way the event was hosted and asked me to conduct such events in the future too. These kinds of activities help children in building their mind set and thinking way which will make them a better person in their life.”

Thank you Ma’am for giving us the opportunity and we hope the participants will be our Safety Ambassadors!

Here are a couple of screenshots of the participants.

On the occasion of Aru’s 30th Birthday

21 Nov 2020
This year we celebrate Aru’s 30th birthday by contributing a little to improve our road conditions.  We do this by encouraging Prakash Foundation founded by Dadarao Bilhore with a mission to make Indian roads safe, by mainly eliminating potholes. As you know, this is very close to our heart as well, and therefore we have made a small donation to fill potholes.
May no family lose a child like Dadarao or us.

SQ Online – Where there is a will

It’s been over seven months since a tiny virus entered countries and brought them to a standstill. What started as a trickle of cases in our country has now become a torrent. The students stay locked up in their houses and teachers are working extra hard facing innumerable challenges in continuing their duty of imparting knowledge. Parents are stressed with their work, looking after their homes and helping their children study besides facing the anxiety of keeping the family healthy and protected.

We have wondered how we can keep spreading the message of safety to the children and the public at large. We have now started taking our marquee Safety Themed quiz contest to schools and involving not just the students but entire families in this effort.

Along with our knowledge partners Walnut Knowledge Solutions, we have held two very successful events this month.

The first one was held for the students of Aaryan Study Circle, Goa on Friday 18 Sep. for the students of Grades 8-9-10. A total of 161 students from various schools from Goa , joined in and had a fantastic time learning some new safety related stuff and revising important messages. A big thanks to Vyankatesh Prabhudessai for helping us organize this event. The top 5 winners of this quiz were

  • Ashish Bhat
  • Adeep Kuncalienker
  • Lavanya Borkar
  • Suhaan Sharieff
  • Aastha L Amonkar

Some of the insights that we got were that about half the students were aware of the 20-20-20 rule. In these times of online classes, it would be appropriate to coach all the students to reduce eye strain.
Only 14% knew the steps of using the fire extinguisher. We certainly have to train our children better in these basic safety techniques.

The second session was held by Kohinoor International School, Thane, on 26 Sep.  and they had also invited students from other schools in Thane to participate. This was indeed a generous gesture on their part.  This was a first for us – a Safety Quest specially designed  for students from Grades 1-4. We had 211 students and their parents join us in this event. A big shout out to Deepali Nene, Principal, and Jignasa Gala who helped us organize the event and mobilise the participation. The image on top was the specially designed invite that Walnut Knowledge Solutions created for this event. Here are the top 5 winners and their details:

  • Anika Kajarekar
  • Saanchi Nangare
  • Dhyaara Jain
  • Atharv Golatkar
  • Hoorfatima

For both the events, the winners received gift vouchers for QShala sessions from Walnut Knowledge Solutions.

We received a good feedback from the participants/ parents. 73% felt that the format of the quiz was a very effective way to learn about safety.

Sharing a few comments here.
Thanks for an enriching session. -Saanchi Nangare
Wonderful session. – Anvay Gadgil
Quiz was amazing. – Vidhi Dessai
Really great session and worth spending time for awareness. – Tamanna Sinha & Anand Sinha
Super fun and it was learning for parents as well. – Naksh Makhija
Amazing and good initiative! – Atique Shagufta

It is heartening when we see that children have internalised some key messages. This is what they told us:
* Safety relates to both indoors as well as outdoor activities..
* Start a habit of using a checklist to reduce errors
* The importance of seatbelts, even in rear seats

Also, a big thanks to the team from Walnut Knowledge Solutions : Vaishnavi, Binila, Vindhya and Raghav.

Here are some pics.

Safety Quest Goes Online!

May 31, 2020 : Safety Quest Amidst The Lockdown

A tiny virus entered the human community, traveled countries through its people and turned the world upside down.
The world came to a standstill.

As schools, colleges, factories and offices closed down, we too cancelled all the awareness sessions we were scheduled to hold. Schools and colleges shifted to online classes and we wondered how we could still continue to spread our message of safety. Our knowledge partners, Walnut Knowledge Solutions had already taken a step to adapt to these circumstances and had started conducting online courses for their flagship Qshala program, which also engages families in quiz programs on weekends. And so, we decided to ride on the Qshala platform to conduct a safety-themed quiz, Safety Quest, online. It wasn’t our usual Safety Quest format. But the team from Walnut did a great job in adapting the content and format to this online medium! They also did a great job in researching the recent developments, and adding some interesting new material.

This is a first for us. Thanks to the Internet, we were able to take this message across the globe. The quiz was held on the national and international level this time! The 31st May turned out to be so special for us.

The Safety Quest received great response in each of our 3 sessions! We had 330 families in Junior, 205 in Sub-Junior and 45 in International round. We had participants from Chennai, Delhi, Bengaluru, Vadodara, Rohtak, Nagpur, Vellore, Cuttack, Navsari, Uttar Kashi, Bhopal, Kolkata, Madurai, Mysore, Pune, Patiala, Tripura, Thane and Mumbai. And international audience from Tokyo, Toronto, Bristol, Copenhagen, Atlanta, Bristol,Dublin, Muscat, Karlsruhe, London, Oslo, California. It was fantastic to see active participation from so many different places. Indeed, it gives us the confidence that we have a mechanism to take Safety Quest to other places very effectively! As per the norms followed for the QShala platform the prizes for the various winners will be shared via Walnut Knowledge Solutions.

What is so exciting is that since this is a family quiz, the parents also joined these sessions and we were able to share safety tips with parents too. There were a few adults, who love quizzes and joined to engage the child in them.

The online platform also gives us an opportunity to seek some feeback on the sentiments of the participants. 92% of the participants said they learnt something out of it! This is very heartening to us.

We received this lovely message from Shalaka Thakur from Mumbai.
“The Arundhati Foundation supported Qshala SafetyQuest today has changed the way my family and I look at safety. Apart from being extremely informative, the way the questions were designed, compel one to think of, not just answers, but the issues underpinning these questions. It made learning about safety fun and engaging. The Arundhati Foundations quiz has really turned around my idea of how Safety Awareness can be spread. Although it was primarily targeted to reach children, I think ( speaking from experience ) that adults would find it equally interesting.”

This is what Bhavani, Class 8 student of Shishu Mandir School, Hellanagar Bangalore had to say. “Having had the opportunity of Qshala workshops last year, I was extremely excited by the thought of joining it. The best thing about this quiz is that we learn without even realising it! The online quiz we attended was very interesting and fun. Safety is a very important topic about which we need to be aware. It was also a good way to spend our lockdown. I would like to thank Shishu Mandir, The Arundhati Foundation and Walnut Knowledge Solutions for this and look forward to attend more of such sessions.”

A few other comments
“Very well researched questions, and fun watching smart kids.” .. Ashok Gapchup
“It was a great program and appreciate the efforts in inculcating safety in children at the right age” .. Ashok R
“The quiz was very very interesting today” .. Akshayalakshmi
“Sorry for the family’s loss, and thanks to them for the wonderful work they are doing” .. Rajiv Ratnam

We, are ever so grateful to Sachin Ravi, Raghav Chakravarty and the entire team of Walnut Knowledge Solutions for the wholehearted support in collaborating with us to help us spread the message of safety.

Attached are screen captures of the various quiz sessions to give you a feel of the audience.
