Tension Limiter Systems help reduce injury during recovery and retrival operations. Common applications for Tension Limiters include construction sites, offshore oil rigs, refineries, and wastewater management plants. Hoist tension limiters are connected between a worker and the winch hoist line. If the worker to be rescued experiences excessive loading, the system applies a clutching or braking action that reduces the potential for bodily injury.

- Personal fall arrest systems are rigged in such a manner that the employee cannot free fall more than 6 feet (1.8 m) or contact a lower level. A free fall may be more than 6 feet (1.8 m) provided the employer can demonstrate the manufacturer designed the system to allow a free fall of more than 6 feet and tested the system to ensure a maximum arresting force of 1,800 pounds (8 kN) is not exceeded. 1910.140(d)(3)
- Body belts. Body belts are prohibited as part of a personal fall arrest system.
