Fall protection safety products prevent people working at heights from falling or decrease the risk of injury if they do fall. On-body products, such as safety harnesses and connecting devices, are worn on or attach to the body to arrest falls or lessen the effects of a fall. Off-body products (such as guardrails, skylight guards, and confined space systems) install on physical structures to prevent falls. Tool tethering and dropped-object products secure tools to anchor points to help prevent injuries to workers and bystanders when objects are dropped from heights. Fall protection products are frequently used in industries where the risk of falling is high, including construction, mining, manufacturing, transportation, utilities, welding, and telecommunications.
