Regulatory references

Forklift Maintenance, Repair, and Return to Service: 29 CFR 1910.178(p)(1)

Every SOP generated from this template cites the paragraphs below, with a plain-language summary of what each one requires. Citations are informational and are not legal advice.

StandardTitleWhat it requires
29 CFR 1910.178(p)(1)Powered industrial trucks: trucks found in need of repair or unsafeIf at any time a powered industrial truck is found to be in need of repair, defective, or in any way unsafe, the truck must be taken out of service until it has been restored to safe operating condition. The rule is triggered by the finding itself, at any time and by anyone, not by a supervisor's agreement that the defect is serious enough.
29 CFR 1910.178(q)(1)Powered industrial trucks: removal from service and authorized repairsAny power-operated industrial truck not in safe operating condition must be removed from service, and all repairs must be made by authorized personnel. In a warehouse this means a truck with a reported defect leaves the fleet immediately, and no operator, lead, or unauthorized helper performs the repair, however small it looks.
29 CFR 1910.178(q)(2)Powered industrial trucks: locations where repairs are prohibitedNo repairs may be made in Class I, Class II, and Class III locations, that is, locations made hazardous by flammable gases or vapors, by combustible dust, or by easily ignitible fibers or flyings. A truck that fails inside such an area is moved or towed out of it before any repair work begins.
29 CFR 1910.178(q)(4)Powered industrial trucks: battery disconnected before electrical repairsTrucks in need of repairs to the electrical system must have the battery disconnected prior to those repairs. The disconnect happens before the technician opens the electrical system, not partway through the job.
29 CFR 1910.178(q)(5)Powered industrial trucks: replacement partsAll parts of an industrial truck requiring replacement must be replaced only by parts equivalent as to safety with those used in the original design. A part that merely fits, or that was salvaged from a different model, does not satisfy this paragraph unless it is equivalent as to safety.
29 CFR 1910.178(q)(6)Powered industrial trucks: alterations and additional counterweightIndustrial trucks must not be altered so that the relative positions of the various parts are different from what they were when originally received from the manufacturer, and must not be altered by adding extra parts not provided by the manufacturer or by eliminating any parts, except as this section provides for approved fuel conversion. Additional counterweighting of fork trucks must not be done unless approved by the truck manufacturer.
29 CFR 1910.178(q)(7)Powered industrial trucks: examination before being placed in serviceIndustrial trucks must be examined before being placed in service and must not be placed in service if the examination shows any condition adversely affecting the safety of the vehicle. The examination must be made at least daily, and where trucks are used on a round-the-clock basis they must be examined after each shift. Defects when found must be immediately reported and corrected.
29 CFR 1910.178(a)(4)Powered industrial trucks: modifications affecting capacity and safe operationModifications and additions which affect capacity and safe operation must not be performed by the customer or user without the manufacturer's prior written approval, and capacity, operation, and maintenance instruction plates, tags, or decals must be changed accordingly. Approval comes first and in writing, and the updated plates are part of completing the work, not an optional follow-up.
29 CFR 1910.145(f)Accident prevention tagsTags must be used to warn employees of hazardous or potentially hazardous conditions, equipment, or operations that are out of the ordinary, unexpected, or not readily apparent, and must remain in use until the identified hazard is eliminated or the hazardous operation is completed. Each required tag carries a signal word and a major message, the signal word readable at a minimum distance of five feet, the major message stating the specific hazardous condition or the instruction to be communicated, with examples given in the standard such as Do Not Start and Do Not Use. The signal word and major message must be understandable to all exposed employees, all employees must be informed of the meaning of the tags used in the workplace, and tags must be affixed as close as safely possible to the hazard by a positive means such as string, wire, or adhesive that prevents loss or unintentional removal.

Compliance checklist

What an inspector looks for

  • A truck found in need of repair, defective, or in any way unsafe is taken out of service at once and stays out until it has been restored to safe operating condition

    29 CFR 1910.178(p)(1)

  • Trucks not in safe operating condition are removed from service, and every repair is made by personnel on the authorized list

    29 CFR 1910.178(q)(1)

  • No repair work is performed in a Class I, Class II, or Class III location; disabled trucks are moved out of classified areas before work begins

    29 CFR 1910.178(q)(2)

  • Fuel and ignition system repairs that involve fire hazards are conducted only in the locations designated for those repairs

    29 CFR 1910.178(q)(3)

  • The battery is disconnected before any repair to the truck's electrical system

    29 CFR 1910.178(q)(4)

  • Replacement parts are equivalent as to safety with the parts used in the original design

    29 CFR 1910.178(q)(5)

  • No truck is altered in the relative position of its parts, by adding parts the manufacturer did not provide, or by eliminating parts, and no counterweight is added without the truck manufacturer's approval

    29 CFR 1910.178(q)(6)

  • Modifications and additions affecting capacity and safe operation are made only with the manufacturer's prior written approval, and capacity, operation, and maintenance instruction plates, tags, or decals are changed accordingly

    29 CFR 1910.178(a)(4)

  • A truck is examined before being placed in service and is not placed in service if the examination shows any condition adversely affecting its safety; defects found are immediately reported and corrected

    29 CFR 1910.178(q)(7)

  • Out-of-service tags carry a signal word readable at five feet and a major message such as Do Not Start, are affixed by a positive means, and stay in place until the hazard is eliminated

    29 CFR 1910.145(f)

  • The key or operator access token of a tagged truck is held in key control so the truck cannot be driven while it waits for repair, and only the maintenance group that resolved the defect removes the tag

  • Each repair is recorded with the unit number, defect, cause, parts used, checks performed, and technician signature, and any manufacturer written approval is filed with the unit record
