OSHA advises drivers to protect themselves from falling in the event that they would have to adjust, tarp, or remove tarp from a load.
In order to protect oneself, drivers could utilize a beam and trolley system, an automated tarping system, horizontal lifeline systems, access platforms, or personal fall-arrest/restraint gear. The driver’s employer is responsible for providing appropriate fall protection.
OSHA also advises that it’s best to use systems that keep the driver off of the truck – eliminating the chances of a fall altogether.
In the event that a driver is working at a host employer’s facility, the fixed-site employer is responsible for providing fall-protection for drivers on-site, and those untarping, or tarping loads.
If fall protection systems are not readily accessible – such as when a driver is on the road, OSHA urges that worker use safe practices.
