Question

1. contact with a current of just ____ can cause extreme pain, respiratory arrest severe muscular contractions, and could even be fatal.

a) 5–10 milliamps
b) 120 milliamps
c) 1,000 milliamps
d) 1 milliamp

1. employers are responsible for verifying that all tool plugs and extension cords

Explanation:

Question 2

To determine the correct current range, we recall electrical safety knowledge: A current of 5 - 10 milliamps can cause extreme pain, respiratory arrest, severe muscular contractions, and be fatal. 1 milliamp is too low, 120 milliamps and 1000 milliamps (1 amp) are much higher and would cause more severe immediate effects, but the range 5 - 10 mA is known to cause these symptoms.

Employers are responsible for electrical safety of tools. Intact ground prongs in plugs/cords are crucial for grounding (preventing shocks). Waterproofing is not a standard verification for all tools, while intact ground prongs are a key safety check.

Answer:

a) 5 - 10 milliamps

Question 3 (assuming the options are about electrical safety for tools):

(Note: Since the options are partially visible, but based on common electrical safety for employers: Employers verify that tool plugs and extension cords have intact ground prongs for safety (to prevent electrical shocks via grounding). Waterproofing is not the main verification here, and other options (if visible) likely don't fit as well as intact ground prongs for electrical safety of tools. If the option is "b) have intact ground prongs", then:
