Screw Jack System Hazards: Manual Adjustments and Worker Safety

What are the potential hazards related to adjusting the struts of a screw jack system?

a) Stand clear of the trench

b) Enter the trench

c) Use heavy machinery

d) Work at night

Answer:

The correct answer is: a) Stand clear of the trench

When operating a screw jack system, the manual adjustment of struts poses potential hazards for workers. The manual adjustment requires the worker to stand clear of the trench to ensure safety. This is important because entering the trench or using heavy machinery can increase the risk of injuries.

In heavy machinery applications, such as backhoes, screw jack systems are used to lift and support heavy loads. However, adjusting the struts of the system manually can be dangerous. Workers need to be cautious and follow safety protocols to prevent accidents.

By standing clear of the trench during the adjustment process, workers can minimize the risks associated with operating a screw jack system. It is crucial to prioritize safety and avoid unnecessary hazards in the workplace.
