Conveyor Operation and Jam Clearing
Safe operation of powered belt, roller, and sortation conveyors covering the pre-start clear-the-line check and startup warning, emergency stop locations and testing, guarding of nip points and power-transmission components, the prohibitions on riding, crossing, and reaching into a moving conveyor, the bright line between clearing a jam from outside with the conveyor stopped and any clearing that requires reaching into the machine under full lockout, package handling at induction and takeaway points, and defect reporting with out-of-service tagging.
- Audience
- All warehouse associates who work on or near powered conveyors, conveyor and sortation operators, induction and takeaway station associates, area leads, and the maintenance technicians authorized to perform lockout

Conveyor Operation and Jam Clearing: 29 CFR 1910.212(a)(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.
| Standard | Title | What it requires |
|---|---|---|
| 29 CFR 1910.212(a)(1) | Machines: types of guarding | One or more methods of machine guarding must be provided to protect the operator and other employees in the machine area from hazards such as those created by the point of operation, ingoing nip points, rotating parts, and flying chips and sparks. On a conveyor the ingoing nip points at drive pulleys, tail pulleys, take-ups, transfers, and powered rollers are exactly the hazards this paragraph requires the employer to guard. |
| 29 CFR 1910.212(a)(2) | Machines: general requirements for machine guards | Guards must be affixed to the machine where possible and secured elsewhere if for any reason attachment to the machine is not possible, and the guard must not offer an accident hazard in itself. |
| 29 CFR 1910.219(e) | Mechanical power-transmission apparatus: belt, rope, and chain drives | Drive belts must be guarded where they run within reach of employees: where both runs of a horizontal belt are seven feet or less from the floor level, the guard must extend to at least fifteen inches above the belt, and vertical and inclined belts must be enclosed by a conforming guard. This paragraph governs the drive belts that power a conveyor, not the conveying surface itself, and the duty applies only where such a drive is present and within seven feet of the floor or working platform. |
| 29 CFR 1910.219(f) | Mechanical power-transmission apparatus: gears, sprockets, and chains | Gears must be guarded by a complete enclosure or another conforming guard, and all sprocket wheels and chains must be enclosed unless they are more than seven feet above the floor or platform. Conveyor drive chains and sprockets at motor couplings and between powered rollers fall under this paragraph when they sit within seven feet of the floor. |
| 29 CFR 1910.147(a)(2)(ii) | Control of hazardous energy: application to servicing during normal production operations | Servicing or maintenance that takes place during normal production operations is covered by the lockout standard if an employee must remove or bypass a guard or other safety device, or must place any part of the body into an area on the machine where work is actually performed on the material being processed or where an associated danger zone exists during a machine operating cycle. An exception exists only for minor tool changes and adjustments and other minor servicing activities that are routine, repetitive, and integral to the use of the equipment for production, and only when the work is performed using alternative measures that provide effective protection. Reaching into a conveyor to free wedged product does not meet that exception at this facility and is performed only under lockout. |
| 29 CFR 1910.147(c)(4) | Control of hazardous energy: energy control procedures | Documented energy control procedures must be developed and used for the control of potentially hazardous energy, and must clearly and specifically outline the scope, purpose, authorization, rules, and techniques to be used, including the specific steps for shutting down and isolating the equipment, the steps for placing and removing lockout or tagout devices, and the requirements for testing to verify the effectiveness of the energy control measures. |
| 29 CFR 1910.147(d) | Control of hazardous energy: application of control | Lockout or tagout must be applied in sequence: prepare for shutdown with knowledge of the energy present, shut the equipment down by its normal stopping procedure, operate all energy isolating devices needed to control the energy, affix lockout or tagout devices so they hold the isolating devices in a safe or off position, relieve or restrain all potentially hazardous stored or residual energy, and verify that isolation and deenergization have been accomplished before servicing begins. |
| 29 CFR 1910.145(f) | Accident prevention tags | Tags must be used to warn employees of hazardous conditions, equipment, or operations that are out of the ordinary, unexpected, or not readily apparent, and must remain in place until the identified hazard is eliminated or the hazardous operation is completed. Each tag must carry a signal word readable at a minimum distance of five feet and a major message understandable to all exposed employees, employees must be informed of the meaning of the tags, and tags must be affixed as close as safely possible to the hazard by a positive means such as string, wire, or adhesive. |
Compliance checklist
What an inspector looks for
Every ingoing nip point at drive pulleys, tail pulleys, take-ups, transfers, and powered rollers within reach of employees is guarded, and no guard is missing, open, or defeated
29 CFR 1910.212(a)(1)
Guards are affixed to the conveyor where possible, are secure, and do not create a hazard themselves
29 CFR 1910.212(a)(2)
Drive belts within seven feet of the floor or a working platform are guarded, and vertical and inclined drive belts are enclosed
29 CFR 1910.219(e)
Drive chains, sprockets, and gears within seven feet of the floor or platform are enclosed
29 CFR 1910.219(f)
Jam clearing that requires removing or bypassing a guard, or placing any part of the body into the machine or its danger zone, is performed only under lockout by an authorized employee
29 CFR 1910.147(a)(2)(ii)
A documented machine-specific energy control procedure exists for each conveyor system, including the stored energy sources such as belt and take-up tension and gravity on inclines
29 CFR 1910.147(c)(4)
Lockout is applied in sequence with all energy sources isolated, stored energy relieved, and zero energy verified by an attempted start before anyone reaches in
29 CFR 1910.147(d)
Out-of-service conveyors are tagged with a danger tag carrying a signal word readable at five feet and a clear major message, attached by a positive means, and the tag remains until the hazard is corrected
29 CFR 1910.145(f)
Emergency stops are unobstructed, known to every associate assigned to the area, and function-tested on the documented schedule
Startup follows a clear-the-line check and warning, and no conveyor is started to test whether a problem has cleared
No employee rides a conveyor, crosses except at a designated crossover, or reaches into, over, or under a moving conveyor
