The preamble of the Occupational Safety and Health Administration’s (OSHA) final rule that established the powered industrial truck (PIT) standard describes a PIT as, “any mobile power-propelled truck used to carry, push, pull, lift, stack, or tier materials.”
Powered industrial trucks can be ridden or controlled by a walking operator. Earth-moving and over-the-road haulage trucks are not included in the definition. Equipment that was designed to move earth, but has been modified to accept forks, is not included.
OSHA’s current standard for PITs requires the equipment to be designed, constructed, maintained, and operated in accordance with the American National Standards Institute (ANSI) B56.1-1969, Safety Standards for Powered Industrial Trucks. In addition, the standard requires that operators be competent to operate a forklift safely, as demonstrated by the successful completion of the specified training and evaluation.
Requirements of the Standards
The standard requires employers to develop and implement a training program based on the general principles of safe truck operation, the types of vehicles being used in the workplace, the hazards of the workplace created by the use of the vehicles, and the general safety requirements of the OSHA standard. Formal (e.g., lecture, video, etc.) and practical (e.g., demonstration and practical exercises) training is to be provided.
Employers also are required to certify that each operator has received the training and to evaluate each operator at least once every three years. Prior to the employee operating the truck in the workplace, the employer is required to evaluate the operator’s performance and determine the operator to be competent to safely operate a PIT. Refresher training is needed whenever an operator demonstrates deficiency in the safe operation of the truck.
All training and evaluation should be conducted by persons with the necessary knowledge, training, and experience to train PIT operators and evaluate their competence. An example of a qualified trainer is someone with:
• A recognized degree, certificate, or professional standing.
• Extensive knowledge, training, and experience who has demonstrated the ability to train and evaluate PIT operators.
Considerations in the Operation of PITs
A counterbalanced PIT typically has a three-point suspension system, meaning the vehicle is supported at three points. This is true even if the vehicle has four wheels. The truck’s steer axle is attached to the truck by a pivot pin in the axle’s center. When the points are connected with imaginary lines, this three-point support forms a triangle called the stability triangle (see Figure 1 at left.)
When the vehicle’s line of action, or load center, falls within the stability triangle, the vehicle is stable and will not tip over. However, when the vehicle’s line of action or the vehicle/load combination falls outside the stability triangle, the vehicle is unstable and may tip over, as shown in Figure 2 on p. 49.
• Always operate the PIT according to the manufacturer’s instructions.
• Always wear a seatbelt when the forklift has one.
• Never exceed the rate load and ensure the load is stable and balanced.
• Do not raise or lower the load when traveling.
• Keep a safe distance from platform and ramp edges.
• Be aware of other vehicles in the work area.
• Have clear visibility of the work area and ensure proper clearance when raising, loading, and operating the PIT.
• Use proper footing and handhold, if available, when entering the lift.
• Use horns at cross aisles and obstructed areas.
• Watch for pedestrians and observe the speed limit.
• Do not give rides or use the PIT to lift people.
