In dimly lit areas, OSHA requires auxiliary lighting on PITs
The hazards commonly associated with powered industrial trucks (PITs) vary depending on the vehicle type as well as the work environment. Even though OSHA does not specify that PITs must be equipped with operating lights, employers must ensure they are equipped with appropriate lighting if the operating area is dimly lit.
In the context of lighting, it’s all about lumens. A lumen is “a unit of luminous flux equal to the light emitted in a unit solid angle by a uniform point source of one candle intensity.” In other words, lumens equal brightness. A typical 60 watt incandescent bulb has brightness equivalent to approximately 800 lumens. Keep in mind that more efficient bulbs (e.g., LED, CFL, halogen) use fewer watts but have the same brightness.
OSHA’s regulation for Powered Industrial Trucks, 1910.178 (h)(2), states: “[w]here general lighting is less than 2 lumens per square foot, auxiliary directional lighting shall be provided on the truck.” The precursor to 1910.178 is American National Standard for Powered Industrial Trucks, Part II, B56.1-1969, which is incorporated into the standard by reference. The latest version, B56.1-2020, Safety Standard for Low Lift and High Lift Trucks, Warning Device 4.10.2 also mentions that the PIT be equipped with lights when operating conditions indicate.
Facilities that are unable to produce a brighter work environment (e.g., operating at night or outdoors) must ensure their PITs are equipped with auxiliary lighting. Auxiliary lighting means a light other than standard equipment lighting. This can include headlights, taillights, directional signals, brake lights, and clearance lights that are used to increase the PIT operator’s visibility to other operators and pedestrians.
Most manufacturers equip PITs with headlights, as well as taillights. However, if your PIT does not come from the factory with this type of auxiliary lighting, you’ll want to equip it with additional sound-producing and visual devices (such as lights or blinkers) where feasible.
While 1910.178 standard does not specifically require flashing lights or back-up beepers, adding these visual and audible warnings can help reduce collisions. Any forklift operations expose workers to hazards, including but not limited to struck by, caught-in-between and crushing by the forklift. The Safety Standard for Low Lift and High Lift Trucks shows that industry recognizes this hazard and that equipping trucks with sound-producing and visual devices are feasible means to abate this hazard. An employer whose workplace presents this hazard and has not taken feasible steps to mitigate it may be in violation of the General Duty Clause.
As a continuous demonstration of a commitment to safety, employers should strive to ensure their employees are operating in a well-lit environment. It is also imperative that employers equip their PITs with sound-producing and visual devices where feasible to abate any potential hazards.
Key to remember: An employer whose workplace presents a hazard caused by a forklift lacking headlights, taillights and/or back-up beepers, may be in violation of the General Duty Clause.
