Every demo super I talk to has a story about a mechanic who got caught reaching into a shear head or a pulverizer while somebody else was still in the cab. Most of those stories end with a close call, not an incident report — but the ones that don't end that way are the reason I keep bringing this topic up. Lockout/tagout on demolition equipment doesn't get the attention it deserves in this industry, and I think I know why: contractors assume OSHA's LOTO rule doesn't really apply to them the way it applies to a manufacturing plant. That assumption is half right, and it's the half that gets people hurt.
Why LOTO Falls Through the Cracks on Demo Sites
Here's the nuance nobody explains clearly enough. 29 CFR 1910.147, the general industry Control of Hazardous Energy standard, does not technically apply to construction work. Construction has its own rule, 29 CFR 1926.417, and it only covers lockout and tagging of electrical circuits — not the mechanical, hydraulic, and stored-energy hazards on an excavator, a high-reach, a concrete pulverizer, or a wire rope crane. So a lot of contractors read that gap as "we don't need a LOTO program." OSHA doesn't see it that way. When a compliance officer finds a mechanic servicing hydraulic attachments without isolating the energy source, they cite it under the General Duty Clause, Section 5(a)(1), or under 1926.20(b)(4) and manufacturer service specs incorporated by reference. I've seen it happen on a demo job in Newark. The absence of a construction-specific mechanical LOTO standard is not a loophole — it's just a different legal path to the same citation, and a heavier one, since general duty citations tend to carry higher penalties when there's an injury attached.
Where the Real Exposure Sits
On a demolition site, the hazardous energy isn't just electrical. It's hydraulic pressure trapped in a shear or pulverizer boom, it's a raised attachment held up by cylinder pressure with no mechanical stop, it's rotating cutting wheels on a wire-pulling rig, and it's stored energy in springs and accumulators on newer high-reach machines. A mechanic climbing up to change a shear tooth or clear a jam needs the same three things every time: the machine shut down, the energy source isolated, and a way to verify zero energy state before hands go near the point of operation. Verbal agreements between the operator and the mechanic — "I'll wait here, don't move it" — are not a program. I see this exact setup fail during preventive maintenance more than during any other task on a demo site, because it happens fast, off to the side, and often without a second set of eyes.
Building a Program That Actually Holds Up
A written energy control program for demolition equipment doesn't need to be complicated, but it needs to be specific to each machine class you run — excavators with attachments, cranes, aerial work platforms, and any powered hand tools used in the demo sequence. It needs machine-specific procedures because a wheeled loader and a 90,000-lb high-reach don't isolate energy the same way. And it needs a person authorized to perform the lockout, not just whoever's standing closest when something jams.
- A written, machine-specific energy control procedure for every class of equipment on site — excavators, high-reach demolition machines, cranes, aerial lifts, and attachments like shears and pulverizers
- Individually assigned locks and tags, with a documented list of who's authorized to apply and remove them
- A verification step before any hands-on work — confirming zero energy state, not just assuming the machine is off
- Group lockout procedures for jobs where more than one trade or crew member is working on the same piece of equipment
- Annual inspection of the energy control procedure itself, not just the equipment — OSHA expects the program to be reviewed, not written once and filed away
- Training records showing authorized employees actually know the specific procedure for the machine in front of them, not a generic LOTO briefing
- A documented process for what happens when a lock has to be removed by someone other than the person who applied it (shift change, no-show, etc.)
What This Looks Like in Practice
The contractors I work with who get this right treat mechanical energy control the same way they'd treat fall protection: written into the site-specific safety plan, tied to the equipment inventory, and reinforced at the toolbox talk level before hydraulic attachment work starts. It's not about paperwork for its own sake. It's about making sure the guy under the shear head isn't trusting a verbal agreement to keep him alive.
This is exactly the kind of gap I help NJ and NY demo contractors close — building energy control procedures that match your actual equipment fleet, not a boilerplate template that doesn't hold up when OSHA asks for it. If your written program hasn't been touched since you bought your current fleet, it's worth a conversation before your next preventive maintenance cycle, not after an incident.
