OSHA Conveyor Safety Standards: Guarding, Lockout, and Penalties

OSHA conveyor safety standards do not exist as a single, unified rule for general industry. Compliance requires piecing together several regulations in 29 CFR 1910, most importantly the machine guarding rules in Subpart O and the lockout/tagout standard at 1910.147. Both of those consistently land on OSHA’s annual list of most frequently cited standards, which tells you where employers keep getting conveyors wrong.¹

Which Regulations Apply to Conveyors

If you’re searching for a regulation titled “Conveyor Safety,” you won’t find one in general industry. Construction has a dedicated conveyor rule at 29 CFR 1926.555, but general industry employers have to work from several standards at once:²

29 CFR 1910.212 — general machine guarding requirements that cover all machines, conveyors included.
29 CFR 1910.219 — mechanical power-transmission apparatus rules for pulleys, belts, chains, and gears.
29 CFR 1910.147 — lockout/tagout procedures for controlling hazardous energy during service and maintenance.
29 CFR 1910.132–138 — personal protective equipment requirements.

Where none of those specifically addresses a hazard on your conveyor, OSHA can still cite you under the General Duty Clause of the OSH Act, which requires employers to keep the workplace free of recognized hazards likely to cause death or serious harm.³

Guarding Every Exposed Moving Part

Every exposed moving part on a conveyor that can injure someone needs a guard. Under 29 CFR 1910.212, employers must protect workers from the point of operation, nip points, and rotating parts using barrier guards, electronic safety devices, or other effective methods.⁴ A nip point is any spot where a body part can get caught between moving components, such as where a belt wraps around a pulley or where two rollers meet. Those are the spots that cause the worst injuries, and they’re often the ones that go unguarded because they look minor until someone loses a finger.

Guards have to be strong enough for normal operating conditions, securely attached to the machine or a nearby fixed structure, and built so workers cannot reach around or through them into the danger zone. A guard an employee can easily remove or bypass defeats the purpose. The guard itself also cannot create a new hazard, like sharp edges or fresh pinch points.

Pulleys, belts, chains, gears, and sprockets that transmit power to the conveyor fall under 29 CFR 1910.219, which sets its own detailed guarding rules for those components.⁵ Where a conveyor passes over work areas, aisles, or walkways, guards must be installed underneath to catch falling materials, and any spot where employees need to cross a moving conveyor requires an elevated walkway with guardrails.² Stepping over or ducking under a running conveyor is the kind of shortcut that feels reasonable in the moment and accounts for a disproportionate share of injuries.

Emergency Stops and Startup Warnings

Every conveyor system needs a way for workers to shut it down immediately. Emergency stop devices must be arranged so the conveyor cannot restart automatically once activated. After an E-stop is triggered, someone has to physically reset the switch and then initiate the normal startup sequence before the conveyor moves again.² The stop control must be available at the operator’s station, and if the operator works remotely from the motor, a stop control also has to be at the motor itself.

For long conveyor runs, industry consensus standards recommend pull-cord E-stops along the full accessible length so a worker can shut things down from any point on the line. No specific general industry OSHA regulation names pull cords, but ASME B20.1 addresses them, and OSHA can enforce recognized practices through the General Duty Clause.

Conveyors must also be equipped with an audible warning signal that sounds immediately before startup.² OSHA does not specify a duration for the signal, though many facilities use three to five seconds as a practical standard. The requirement matters most for conveyors with automatic or remote start capability, where no one standing near the equipment may know it’s about to move. In high-noise environments, ASME B20.1 addresses visual signals such as flashing lights alongside the audible alarm.

Lockout/Tagout for Service and Maintenance

Any time someone services, maintains, or clears a jam on a conveyor, 29 CFR 1910.147 applies. The regulation exists to prevent the one scenario responsible for the most severe conveyor injuries: the machine unexpectedly starting while someone’s hands are inside it.⁶

Employers must develop, document, and implement written energy control procedures for each conveyor. The written procedure has to account for every energy source on the system, not just the obvious electrical supply. Conveyors often carry hydraulic pressure, pneumatic energy, spring tension in take-up mechanisms, and the gravitational energy of material sitting on an inclined belt. Miss one and the lockout is incomplete.

Before maintenance begins, the machine must be isolated from all energy sources and rendered inoperative. The authorized employee performing the work places a personal lock on each energy-isolating device, and nobody else can remove that lock. In group maintenance, each worker applies their own lock to a group lockout device and removes it only when their part of the job is finished.

Energy control procedures must be inspected at least once per year. The inspection has to be performed by an authorized employee who does not routinely use that particular procedure, which brings fresh eyes to habits that drift over time. Where lockout is used, the inspector reviews responsibilities with each authorized employee. The employer must certify that inspections occurred, documenting the machine, date, employees involved, and inspector.⁶

Training Three Categories of Employees

OSHA recognizes three distinct categories of employees around lockout/tagout, each needing a different level of instruction.⁶

Authorized employees, who perform lockout/tagout, must be trained to recognize all hazardous energy sources on the equipment they service, understand the type and magnitude of that energy, and know the specific methods for isolating and controlling it.
Affected employees, who operate the conveyor or work near it, must understand the purpose of energy control procedures and know not to attempt restarting equipment that has been locked or tagged out.
Other employees who simply work in areas where lockout/tagout might be in progress must be instructed on the procedure and told never to tamper with locks or tags.

All employees who operate or work near conveyors also need training on conveyor-specific hazards: pinch points, entanglement risks, and the dangers of loose clothing, jewelry, or long hair near moving parts. They must know what startup warning alarms mean, and they must understand that riding on a conveyor is prohibited.

Initial training is not enough. Retraining is required whenever a job assignment changes, new equipment or processes introduce different hazards, or energy control procedures are revised. It’s also triggered when a periodic inspection reveals employees have deviated from procedures or show gaps in knowledge. The employer must certify training with each employee’s name and training dates.

PPE Around Conveyor Operations

Where hazards cannot be fully eliminated through guarding or other engineering controls, OSHA requires personal protective equipment. Under 29 CFR 1910.132, the employer must conduct a hazard assessment of the workplace and select PPE that addresses the specific risks each employee faces.⁷ For conveyor operations, that typically means hard hats where there’s risk of falling objects from overhead conveyors, safety glasses where flying particles are present, and appropriate gloves for material handling. OSHA guidance specifically identifies “working around or under conveyor belts which are carrying parts or materials” as a situation requiring head protection.

One nuance matters here: loose gloves, baggy sleeves, or dangling lanyards near moving conveyor components can create the entanglement hazard PPE is supposed to prevent. The hazard assessment needs to address that tradeoff and specify close-fitting alternatives where appropriate.

The General Duty Clause and ASME B20.1

Because OSHA’s general industry standards don’t address every possible conveyor hazard, the General Duty Clause fills the gaps. Section 5(a)(1) of the OSH Act requires a workplace “free from recognized hazards that are causing or are likely to cause death or serious physical harm.”³ OSHA can use it when no specific standard covers a hazard, provided the hazard is recognized and a feasible fix exists.

That is where ASME B20.1, the Safety Standard for Conveyors and Related Equipment, becomes practically enforceable. OSHA’s construction conveyor standard explicitly incorporates ANSI B20.1 by reference, and in general industry, OSHA points to ASME B20.1 as evidence that a hazard is recognized by the industry.² If B20.1 calls for a specific safeguard and you haven’t implemented it, OSHA has a straightforward path to a citation. Treating ASME B20.1 as a voluntary reference document you can ignore is a common and expensive mistake.

Penalties for Non-Compliance

OSHA adjusts civil penalties annually for inflation. As of the adjustment effective January 2025, the maximum penalty for a serious violation is $16,550 per violation, and the maximum for a willful or repeat violation is $165,514 per violation.⁸ Those figures will be adjusted again in early 2026. A single conveyor with missing guards, no lockout/tagout procedures, and untrained workers can generate multiple citations, each carrying its own penalty.

Machine guarding and lockout/tagout appear on OSHA’s top 10 most cited standards year after year.¹ That persistence means inspectors know exactly what to look for on a conveyor, and the common findings are predictable: guards removed for maintenance and never replaced, lockout/tagout procedures that exist on paper but aren’t followed, and employees who were never trained on the equipment they operate daily. The financial penalties sting, but the real cost of a conveyor safety failure is measured in amputations and fatalities that were entirely preventable.
