Fall arrest system
A personal fall arrest system (FAS) is a system designed to minimise injury if a worker should fall from a significant height and experience impact. The purpose of the system is not to stop the fall (that is the purpose of a fall restraint system or fall prevention system), but to limit the injuries that could happen to a worker as a result of the fall's impact.
These systems must be professionally installed and should be regularly inspected to ensure compliance with health and safety and CDM regulations (Construction Design and Management) regulations. These can be internal inspections carried out by the contractor, third party audits or external inspections by the Health and Safety Executive.
Fall arrest systems should be replaced when necessary. Training is required for proper usage.
