Massachusetts Hoisting License Practice Test

What height must fences used as barricades around trenches be, according to regulations?

1. At least four feet high

2. At least six feet high

3. At least eight feet high

4. Any height as long as they fulfill visibility requirements

The correct answer is: At least six feet high

Fences used as barricades around trenches must be at least six feet high, as this height is specified to provide adequate protection and prevent accidental falls into the trench. The six-foot requirement helps ensure that individuals cannot easily climb over the barricade and minimizes the risk of unauthorized access to the hazardous area. This regulation is in place to enhance safety on construction sites and protect workers and the public from potential injury caused by trench hazards. The other heights provided in the choices do not meet the safety standards set by regulations, as four feet may not offer sufficient deterrence and visibility for workers, while eight feet is excessive and unnecessary for the purpose of barricading trenches. Allowing any height as long as visibility requirements are met would also compromise safety, as visibility alone does not provide the physical barrier needed to protect against accidental entry or falls.
