Red Seal Electrician Practice
Safety and work practicesQuestion 667 of 1506

An electrician says that normal shoes will protect against a shock from the ground. What does the text say about this?

  1. Most soles are too thin and unsuitable, and moisture makes it worse.
  2. Any shoe with a rubber heel gives full protection at any voltage.
  3. Wet leather insulates better than dry leather does.
  4. Shoes only matter when the voltage is DC and not AC.
Show answer

Correct answer: Most soles are too thin and unsuitable, and moisture makes it worse.

Only shoes made for electrical work, kept clean and dry, can be counted on to insulate.
