Question

Walkways must have handrailsWhen at ________ or more above lower level.

Option 1: 3 feet
Option 2: 5 feet
Option 3: 7 feet
Option 4: 10 feet

Answer 1

Walkways must have handrails when they are 4 feet or more above a lower level for safety. When dropping objects from heights, safety protocols such as keeping a safe distance from edges and avoiding dropping objects over populated areas are crucial.

Step-by-step explanation:

Walkways must have handrails when they are at 4 feet or more above a lower level. This is a safety regulation to ensure that individuals are protected from falls when using walkways that are significantly elevated above the ground or another surface. When conducting experiments that include dropping objects from different heights, safety precautions are particularly important.

Make sure to stay a safe distance from the edge to prevent any risks of falling, do not lean over railing too far, and take care not to drop objects into areas where they could cause harm to people or vehicles. Such experiments may require marking out distances at intervals, like a line of one foot, two feet, and so on, to measure the dropping distances accurately.
