Final answer:
OSHA regulations require a safety harness to be secured to a support capable of holding 5,000 lbs to ensure worker safety.
Step-by-step explanation:
The Occupational Health and Safety Administration (OSHA) regulations are the American national standards developed to ensure workplace health and safety for all employees. OSHA's primary rule is that employers are obligated to provide a safe workplace environment.
According to OSHA regulations, a safety harness must be secured to a structural member above the worker that is capable of supporting a minimum deadweight of 5,000 lbs. OSHA standards ensure the safety of workers by requiring the use of appropriate personal protective equipment and fall protection systems, among other safety measures. This regulation is a part of the fall protection requirements that protect workers from fall hazards by ensuring the anchorage point for a fall arrest system is sufficiently strong.
