Step-by-step solution for: Are You Safety Savvy? - Electrical Safety Foundation
Here are the correct answers for the safety quiz, with a brief explanation for each to help you understand why.
1. False
Using a corded telephone is dangerous during a storm because lightning can travel through the phone lines and shock you. Wireless or cell phones are safer.
2. b. The third prong is the “ground”
The round third prong on a plug connects to the ground wire in your house. This provides a safe path for electricity to escape if there is a short circuit, preventing shocks.
3. e. All of the above
All the listed steps are important safety rules. You must keep generators outside to avoid carbon monoxide poisoning, use a transfer switch to protect utility workers, and ensure the generator is grounded.
4. d. construction
The construction industry has high rates of electrical accidents because workers frequently interact with temporary power sources, exposed wiring, and heavy machinery near power lines.
5. c. the equipment malfunctioned
While wet conditions are dangerous, the most common cause of electrocution from power tools is when the tool itself breaks or malfunctions (for example, if the internal wiring becomes exposed).
6. c. year
Smoke alarm batteries should be tested monthly and replaced at least once a year. A good habit is to change them when you change your clocks for Daylight Saving Time.
7. d. All of the above
Swimming near docks is risky because boats might not see you, there could be sharp hooks on the bottom, and stray electricity from boats can electrify the water.
8. c. 75%
Studies show that young children (ages 2-4) are very quick and dexterous; about 75% of them can remove plastic outlet covers in less than ten seconds. This is why locking outlets are recommended.
9. a. 23 seconds
Fire spreads incredibly fast. In the U.S., a fire department responds to a fire roughly every 23 seconds.
10. b. shuffle away with small steps, keeping your feet together and on the ground at all times
If a power line falls, it creates an energy field in the ground. If you take big steps, one foot might be in a high-voltage area and the other in a low-voltage area, causing electricity to flow through you. Shuffling keeps your feet at the same voltage level.
11. a. True
Electricity can "arc" or jump through the air from a power line to a conductive object like a tree trimmer, even if they aren't touching directly.
12. a. True
Button-cell batteries contain strong chemicals. If swallowed, they can burn through tissue in the esophagus in just two hours, which can be fatal.
13. d. Adults over 65
Statistically, adults over the age of 65 have the highest risk of dying in a fire, often due to mobility issues or slower reaction times.
14. b. The unique skin on the feet of birds protects them
Birds can sit on wires safely because their feet have a special insulating layer. Also, since they only touch one wire, the electricity has no path to flow through them to the ground.
15. d. b and c
When new electrical codes are adopted, they usually apply immediately to new buildings and any renovations or updates being done to existing buildings.
