5 Common Misconceptions About OSHA 1910.147 Lockout/Tagout in Trucking and Transportation

Lockout/Tagout (LOTO) under OSHA 1910.147 isn't just a factory floor ritual—it's a lifeline in trucking operations too. Yet, in transportation hubs buzzing with diesel fumes and hydraulic whirs, myths persist that leave mechanics exposed and compliance in the dust. I've walked plenty of shop floors where a supervisor waves off LOTO as 'overkill for trucks,' only to watch a near-miss unfold. Let's debunk the top five misconceptions about OSHA 1910.147 in trucking, backed by the standard itself and real-world grit.

Misconception 1: LOTO Doesn't Apply to Mobile Equipment Like Trucks

Trucks roll, so the thinking goes: OSHA 1910.147 must be for stationary machines only. Wrong. The standard covers any servicing or maintenance exposing workers to hazardous energy in general industry, including transportation. Think hydraulic tailgates, air brake systems, or battery jumps on semis—these pack stored energy that can crush or shock without proper isolation.

OSHA's preamble to 1910.147 explicitly includes vehicle maintenance shops. In my experience auditing trucking fleets, ignoring this led one California yard to a $50K citation after a mechanic tangled with a pressurized air line. De-energize fully: disconnect batteries, bleed lines, and lock it out.

Misconception 2: Wheel Chocks Alone Satisfy LOTO Requirements

Chock the wheels, call it safe—common in loading docks and trailer servicing. But chocks control motion from gravity, not all hazardous energy sources under 1910.147. What about hydraulic rams on dump trucks or pneumatic tools? Those demand full energy control: shutdown, isolation, bleed-down, and lock/tag.

• Short punch: Chocks prevent rollback; LOTO prevents unexpected startups.
• OSHA cites 1910.147(c)(4) for energy control procedures—wheel chocks are a supplement, not a sub.

We've seen incidents where chocked trailers shifted under hydraulic pressure, pinching fingers. Pair chocks with LOTO for the win.

Misconception 3: Tagout Is Just as Good as Lockout

Tags are cheap and quick, so why bother with locks? OSHA 1910.147 prioritizes lockout because tags can be ignored or removed accidentally—especially in high-turnover trucking shops where shifts swap mid-job.

Tagout is allowed only if the employer documents why lockout isn't feasible (like group lockouts on shared fleet equipment) and trains everyone rigorously. A playful nudge: tags whisper 'don't start'; locks scream 'you physically can't.' Data from OSHA shows lockout reduces incidents by 90%+ in energy control scenarios. Don't gamble on good intentions.

Misconception 4: LOTO Is Only for Major Repairs, Not Routine Maintenance

Oil changes or brake checks? Skip LOTO, right? Nope. 1910.147 applies to any task where unexpected energization could harm: minor servicing included. In trucking, that's tire rotations near spinning hubs, welding on frames with live batteries, or greasing kingpins under load.

Exceptions exist for 'minor service activities' that are routine, repetitive, and low-risk with no exposure—but prove it in your procedures. I've consulted fleets where skipping LOTO on 'quick lubes' led to ejections from liftgates. Train your teams: if it exposes energy, lock it.

Misconception 5: PPE Replaces the Need for Lockout/Tagout

Gloves, glasses, hard hats—PPE got this, yeah? PPE protects against contact hazards; LOTO prevents the hazard from existing. OSHA 1910.147 is about control, not mitigation—relying on PPE alone violates the hierarchy of controls.

In transportation, a flash from a shorted truck battery or hydraulic snap ignores your gloves. Combine them: LOTO first, PPE second. Research from the National Safety Council underscores LOTO's edge in preventing fatalities.

Clearing the Road Ahead: Actionable LOTO Steps for Trucking

Bust these myths by auditing your program against 1910.147. Develop truck-specific procedures: identify energy sources (electrical, hydraulic, mechanical, pneumatic), train annually, and verify zero energy before work starts. Tools like energy-isolating devices tailored for fleets make it painless.
