Final answer:
OSHA requires fall protection measures when workers are exposed to falls of 6 feet or more to a lower level, which can include harnesses, safety lines, or guardrails.
Step-by-step explanation:
Fall protection measures are required when workers are exposed to a possible fall of 6 feet or more to a lower level. According to the Occupational Safety and Health Administration (OSHA), employers must provide fall protection for their employees who are performing work at heights.
This can include safety measures such as harnesses, safety lines, or guardrails. The requirements not only apply to construction industries but also to general industries, maritime work, and agriculture when such risks are present. Furthermore, employers are required under the General Duty Clause of the OSHA to maintain a workplace environment free of recognized hazards that could cause serious harm or death, even if no specific standard applies.
