The answer is C: 400 lbs.
A safety net can absorb the force of a 400 pound bag which is equivalent to 180 Kgs. This much weight is tested from the highest level of height from which the potential fall might occur and from which employees are exposed to fall hazards. This net shall be capable of absorbing an impact force that is equal to that produced by the drop test. All this is a requirement for the safety and health regulations for construction (fall projection). The 400 pound bag is 28 to 32 inches in diameter.
