Lightning Safety Quiz

Today is the last day of lightning safety week for 2014. Before you quiz yourself on your lightning safety knowledge, please take a look at this presentation on Lightning Myths.  While the information presented isn’t in the quiz, it just might save your life.

Lightning Safety Quiz

Question 1
A person who has been struck by lightning...
A
...has very little chance of survival.
Hint:
Contrary to the common crispy critter image of people who have been struck by lightning, about 90% survive.
B
...should be administered CPR if they are unconscious and not breathing.
Hint:
Correct. Way to go! If you don't have CPR training, consider getting it. Your community Recreation Department or Red Cross may have training available.
C
...should not be touched for at least 60 seconds because his/her electrified body may shock you as well.
Hint:
While the human body is about 60-70% water and is a good conductor of electricity, IT DOES NOT STORE a charge. People who have been struck are safe to touch and should be helped immediately!
D
...is affected by both their electrified body and have little chance of survival.
Hint:
These are the two myths often associated with lighting! About 90% survive a lightning strike and the body DOES NOT STORE a charge!
Question 1 Explanation: 
CPR should be administered AS QUICKLY AS POSSIBLE! You will not be shocked because the human body DOES NOT STORE an electric charge.
Question 2
How much energy does the AVERAGE lightning bolt carry?
A
30 million volts/100 thousand amps
Hint:
Too high for the AVERAGE lightning bolt.
B
1 thousand volts/30 million amps
Hint:
Way too low!
C
30 thousand volts/1 million amps
Hint:
Too high!
D
100 million volts/30,000 amps
Hint:
Yes!
E
Lightning is too powerful to measure accurately
Hint:
Try again. Energy of a lightning bolt is measurable.
Question 2 Explanation: 
However, it can carry up to a BILLION volts and 300,000 amps!
Question 3
You observe a lightning flash and then hear thunder 10 seconds later. How far away was the lightning bolt.
A
5 miles
Hint:
It's closer than that. Have you taken appropriate shelter?
B
2 miles
Hint:
Yes! Have you taken appropriate shelter?
C
10 miles
Hint:
It's closer than that. Have you taken appropriate shelter?
D
3 miles
Hint:
It's closer than that. Have you taken appropriate shelter?
Question 3 Explanation: 
Two miles is very close. The next lightning strike will be within 2-3 miles of the previous one so it could be near you. Take shelter!
Question 4
What are your odds of being struck by lightning?
A
1:600,000
Hint:
Good guess, but not the right answer. What factors might decrease your odds of being struck by lighting?
B
1:750,000
Hint:
Good guess, but not the right answer. What factors might decrease your odds of being struck by lighting?
C
1:3,000,000
Hint:
Good guess, but not the right answer. What factors might decrease your odds of being struck by lighting?
D
1:2,000,000
Hint:
Good guess, but not the right answer. What factors might decrease your odds of being struck by lighting?
E
No single answer can be applied to everyone
Hint:
Good job!
Question 4 Explanation: 
Your odds of being struck depend on several different factors, and these vary from person to person. It is impossible to assign one single probability to every person on the planet.
Question 5
30 seconds between the flash of lightning and first sound of thunder indicates the bolt was _________ miles away.
A
3
Hint:
Too close. Remember - when thunder roars, go indoors!
B
10
Hint:
Too far. Remember - when thunder roars, go indoors!
C
30
Hint:
Too far. Remember - when thunder roars, go indoors!
D
6
Hint:
Correct! Remember - when thunder roars, go indoors!
Question 5 Explanation: 
Remember, each five seconds from flash to sound represents one mile. 30 seconds divided by five seconds per mile equals six miles.
Question 6
Which of the following can you depend on to protect you from lightning?
A
A small cluster of trees
Hint:
Putting yourself near or making yourself the tallest object in the area only increases your chances of being struck.
B
A convertible automobile
Hint:
At 50,000 degrees Fahrenheit, lightning will vaporize your convertible top. Contrary to popular belief, those rubber tires will NOT insulate you from a strike. If you use a vehicle to protect yourself from lightning, make sure it's a hardtop!
C
A picnic shelter or pavilion
Hint:
Picnic shelters and pavilions have open walls and are highly susceptible to ground streamers and side flashes
D
A baseball dugout
Hint:
The open front of the dugout makes it susceptible to ground streamers and side flashes.
E
None of the above
Hint:
Correct.
Question 6 Explanation: 
A sturdy building with plumbing and electrical wiring (like your average house) is the best place to go. An all-metal vehicle makes a decent alternative if no buildings are nearby.
Question 7
What should your lightning safety plan take into account?
A
Where they will evacuate to
Hint:
Knowing where to evacuate to is important but there is more.
B
How many people will have to find shelter
Hint:
Certainly you need to know how long it will take to get everyone to shelter but that alone is not enough.
C
How long it will take them to get there
Hint:
Obviously, the greater numbers of people will require greater evacuation times, which in turn will determine when your lightning safety plan should be put into effect. But there is more to know and be apart of your safety plan.
D
The latest weather forecast.
Hint:
It is true that weather can change quickly and sometimes unexpectedly. Keeping abreast of the latest conditions will reduce your chances of being caught off guard. But just getting the latest forecast is not enough.
E
All o f the above
Hint:
Yes!
Question 7 Explanation: 
Weather can change quickly and sometimes unexpectedly. Keeping abreast of the latest conditions will reduce your chances of being caught off guard. Greater numbers of people will require greater amounts of space. Evacuating to a shelter that provides no protection from lightning defeats the entire purpose of a lightning safety plan to begin with! Greater numbers of people will require greater evacuation times, which in turn will determine when your lightning safety plan should be put into effect.
Question 8
Thunder...
A
...travels about one mile, or about one and one half kilometers, every second.
Hint:
This is a potentially fatal error because it will cause you to grossly overestimate your distance from a lightning strike: Using the flash-to-bang method, if you count ten seconds from a lightning flash to the subsequent bang of its thunder, the lightning DID NOT hit ten miles away...
B
...travels about one mile every 5 seconds, or about one kilometer every 3 seconds.
Hint:
Excellent!
C
...can easily be heard from a storm more than 10 miles away.
Hint:
On clear nights with no wind, thunder can be heard beyond 10 miles. But in the vast majority of cases, the atmosphere will absorb the sound wave well within the 10 mile range.
D
...is a loud, but completely harmless side effect of lightning.
Hint:
In most cases, thunder is harmless. However, if you are within the immediate strike zone, it can be loud enough to permanently damage your hearing.
Question 8 Explanation: 
You can estimate your distance from a lightning strike by using the "flash-to-bang" method: Count the seconds from a lightning "flash" to the subsequent "bang" of its thunder, and divide by 5 (for miles) or by 3 (for kilometers).
Question 9
The sound of thunder from a lightning bolt one mile away will typically have a ______________ sound.
A
low rumbling
Hint:
Try again.
B
soft rumbling
Hint:
Try again.
C
dull booming
Hint:
Try again.
D
sharp crackling
Hint:
Yes.
Question 9 Explanation: 
The sharp sound comes from the distinct shock wave. The farther the sound travels, the less defined the shock wave becomes dulling its impact.
Question 10
Lightning is the first thunderstorm hazard to arrive, and the last to leave.
A
True
Hint:
Well done!
B
False
Hint:
Lightning can strike more than 10 miles from its parent thunderstorm, while tornadoes, hail, micro-bursts, and heavy rain are limited to the storm boundary.
Question 10 Explanation: 
If you hear thunder, you are close enough to be struck by lightning. Seek indoor shelter immediately!
