Lockout/Tagout on Demolition Equipment: What NJ Contractors Need in Writing
A machine that has been shut down may still move or release stored energy. Before clearing a jam or servicing an attachment, identify what can move and the procedure for that machine.
Start with the rule that fits the task
29 CFR 1910.147 excludes construction employment from its scope. Construction standards address particular tasks and equipment: 29 CFR 1926.417 covers tagging controls and de-energized circuits, while 29 CFR 1926.702(j) requires locking and tagging potentially hazardous energy sources before maintenance or repair of specified concrete and masonry equipment when inadvertent operation could injure someone. Check the rule that fits the machine and task; one general-industry procedure does not apply to every construction machine.
Plan for the work, not just the shutdown
Clearing a jam or working on an attachment can expose a worker to stored or unexpected energy. Identify each source and how it will be controlled before anyone starts hands-on work.
Make any written steps fit the equipment
Start with the manufacturer’s instructions, the task and the construction rule that applies. Where a written procedure is required by the applicable standard or employer program, make it specific to the equipment, energy sources, isolation points and how the worker will verify the required controls.
- What energy sources and isolation points need to be addressed for this machine and attachment?
- Who is authorized under the employer’s procedure to apply, verify and remove locks or tags?
- How will the worker verify the machine cannot move or release energy before hands-on work?
- If several people are exposed, how will each person’s protection and any shift handoff be managed?
- Has the procedure been reviewed after a change to the equipment or the work?
- What task-specific instruction do the involved employees need under the applicable rule and employer procedure?
- If a lock or tag must be removed while the person who applied it is unavailable, what does the employer’s procedure require?
Before service begins
Use the procedure that applies to the equipment and task. Identify the energy sources, follow the required isolation steps and verify the controls before reaching into, under or against a machine.
