What is the formula for determining Working Load Limit (WLL)?

The formula for determining the Working Load Limit (WLL) is WLL = BLL / Safety factor. This reflects a crucial concept in safety practices related to lifting and rigging operations.

The Breaking Load Limit (BLL) is the maximum load that a piece of equipment can withstand before failure occurs. The Safety factor is a crucial multiplier that accounts for uncertainties in the application of the equipment, such as dynamic loads, wear and tear, and environmental conditions. By dividing the BLL by the Safety factor, you are effectively reducing the maximum safe load the equipment can handle in practical applications to ensure safety. This approach is essential in preventing accidents and ensuring the equipment is not overloaded during use, which is vital in both industrial and construction contexts.

In contrast to this, other options suggest adding or subtracting the safety factor, which would not yield a safe or accurate representation of the WLL.
