Answer 1

The correct answer to the question on ladder safety is that an employee is not allowed to stand or work on the top three rungs of a ladder without a personal fall arrest system.

Step-by-step explanation:

The question asks about safety regulations concerning the use of ladders in a workplace. According to most safety standards, such as those set by the Occupational Safety and Health Administration (OSHA), unless an employee is protected by a personal fall arrest system, no one should stand or perform work on the top three rungs of a ladder. This rule is in place to prevent falls and injuries that may occur when someone is working from an unstable position at the top of a ladder. Therefore, the correct answer is C) Three.
