Question

what is the criteria for a guard having to be used on a machine? select the best option. ○ guards on machines are unnecesary ○ only if you feel like a guard is needed ○ only if your employer decides a guard is necessary

Explanation:

The first option is incorrect as machine guards are often necessary for safety. The second option is wrong because safety criteria for machine guards aren't based on personal feelings. The third option is correct as employers, considering safety regulations and workplace needs, decide if a guard is necessary to protect workers from machine - related hazards.

Answer:

C. Only if your employer decides a guard is necessary (assuming the options are labeled A, B, C with A being "Guards on machines are unnecessary", B being "Only if you feel like a guard is needed", and C being "Only if your employer decides a guard is necessary")
