When using harnesses, lifelines and lanyards, Cal/OSHA states that lifelines shall be secured above the point of operation to an anchorage or structural member capable of supporting a minimum dead weight of how many pounds?

When using harnesses, lifelines, and lanyards, it is essential that lifelines are anchored correctly to ensure the safety of workers who might be operating at heights. Cal/OSHA mandates that lifelines must be secured to an anchorage or structural member that can support a minimum dead weight of 5,000 pounds. This requirement is established to ensure that the anchorage point can withstand the forces that could be exerted in the event of a fall, providing adequate safety and preventing serious injury or fatal accidents.

The choice of 5,000 pounds is not arbitrary; it is based on rigorous safety analysis which considers the dynamics of a fall and the impact forces involved. This level of strength offers a significant safety margin during unexpected incidents.

The other options suggest lesser strengths, which do not meet the cal/osha standards for anchorage and could lead to unsafe conditions in a fall situation. Ensuring the anchorage is robust minimizes risks and provides essential protection for workers engaged in tasks at elevations.
