A class C hard cap will suffice, as long as you are not exposed to electrical hazards in the job. A class C hard cap offers protection against falling objects, bumps and minor hits against walls or low roofs, but does not offer any kind of electrical protection.
According to the Occupational Safety and Health Administration, there are 3 scenarios in which you should wear a hard cap at work.
- 1. If it is likely that falling objects strike you.
- 2. If you could hit yourself in the head against fixed objects, walls, platforms.
- 3. If you are exposed to any kind of electrical damage.
Since you will only be exposed to minor bumps, the Class C will be enough to keep you safe from harm.
