Maximum Arresting Force (MAF)
Definition - What does Maximum Arresting Force (MAF) mean?
Maximum arresting force (MAF) is the peak dynamic force exerted on a body while a fall is being arrested. It is used in OSHA regulations to determine the safe use of harness equipment.
Safeopedia explains Maximum Arresting Force (MAF)
Maximum arresting force is determined by the weight of the worker, the length of the lanyard, the distance of the free fall and ability of the fall arrest system to absorb the energy associated with the fall. By minimizing the arresting force, there is a minimized potential for injury. As an example, OSHA standard 1926.502(d)(16)(ii) states that the maximum arresting force for a worker in a safety harness weighing up to 310 pounds shall not be exposed to a maximum arresting force in excess of 1,800 pounds.
