Occupational Head Protection
Each affected employee shall wear protective helmets when working in areas where there is a potential for injury to the head from falling objects. Protective helmets designed to reduce electrical shock hazard shall be worn by each such affected employee when near exposed electrical conductors which could contact the head.
Although the OSHA standards themselves do not identify specific occupations or applications where head protection is required, there are some examples:
Some examples of occupations for which head protection should be routinely considered are: carpenters, electricians, lineman, mechanics and repairers, plumbers and pipe fitters, assemblers, packers, wrappers, sawyers, welders, laborers, freight handlers, timber cutting and logging, stock handlers, and warehouse laborers.”
