Lockout/Tagout Procedure Template

A machine specific energy control procedure is the written document that records how one piece of equipment is shut down, isolated from every energy source, locked, verified de-energized and returned to service. OSHA requires one per machine under 29 CFR 1910.147(c)(4). A facility-wide lockout/tagout policy is a programme, not a procedure, and does not satisfy the requirement.

Scope errors run both ways. Some facilities write procedures for equipment the standard never covered, burning effort that should have gone to the machines that could actually kill someone. Others assume an exemption applies and leave a real gap. Both show up in audits, and the second one shows up in incident reports.

The template has four sections. The first identifies the equipment, the second inventories energy, the third carries the mandated sequence and the fourth records coverage and sign-off. The middle steps are numbered because the regulation makes them a sequence: 1910.147(d) states the elements shall be done in the order given, and performing them out of order is itself a deviation.

1. 01

   Prepare for shutdown(d)(1)

   Record what the authorized employee must know before touching anything: the energy types present, their magnitudes, the hazards each presents, and the means of control. Note affected employees who must be told before controls go on, per (c)(9).

2. 02

   Shut down the equipment(d)(2)

   Specify the normal shutdown method for this machine. The standard calls for an orderly shutdown that avoids creating a new or increased hazard. Abruptly dropping power to a loaded conveyor or a heated vessel can be more dangerous than a controlled stop.

3. 03

   Isolate every energy source(d)(3)

   One line per isolating device, in the order they are operated, with the device identifier and location. Where the walk route matters, say so. A crew that isolates the main disconnect and misses the compressed air header has not isolated the machine.

4. 04

   Apply locks and tags(d)(4)

   Each authorized employee affixes their own device. Devices must be singularly identified, used for nothing else, standardized within the facility by colour, shape or size, and must indicate who applied them (c)(5)(ii). Where a tag cannot attach to the device directly, it goes as close as safely possible and in a position obvious to anyone about to operate it.

5. 05

   Relieve stored energy(d)(5)

   Name each stored energy source and the specific action that renders it safe: bleed the accumulator, block the ram, discharge the capacitor bank, chock the roll, allow the surface to cool below a stated temperature. Where energy can reaccumulate, (d)(5)(ii) requires verification of isolation to continue for the duration of the work.

   Most frequently omitted section in procedures we review.

6. 06

   Verify isolation(d)(6)

   State the verification method for each source and who performs it. For electrical, that means testing with a meter proven live-dead-live, not observing an indicator lamp. For pneumatic and hydraulic, a gauge reading at zero. For mechanical, an attempted start with controls returned to the off position afterward. Verify de-energized written without a method is the wording inspectors flag most often in this section.

1910.147 was issued in 1989 and its core text has changed little since. Two developments are worth tracking if you are writing procedures for automated equipment.

Nine of the ten findings above are not failures of safety knowledge. They are failures of follow-through: a procedure that never got revised, an inspection that slipped past its window, a training record with a gap. That is coordination work, and it is what the agents take off your team.

KnowSafe

Holds the procedure library keyed to your asset register, flags assets with no current procedure, and schedules the annual periodic inspection with the four required certification fields captured on completion.

KnowMaintain

Watches work orders and asset changes. When equipment is modified, it opens a procedure revision task and links it to the change, closing the gap that produces stale procedures.

KnowTrain

Maintains the authorized and affected employee roster with training certification by name and date, and triggers retraining when a procedure revision or job change occurs.

Ella

Coordinates the three, aggregates coverage and completion into one view, and holds every write for your approval before it touches a record.

Authorized employee

A person who locks or tags out equipment in order to service or maintain it. An affected employee becomes authorized when their duties include that servicing.

Affected employee

Someone whose job requires them to operate the equipment being serviced or work in the area. They do not apply locks but must be notified before and after.

Energy isolating device

A mechanical device that physically prevents transmission or release of energy: a breaker, disconnect switch, line valve or block. Push buttons and selector switches are excluded.

Energy source

Any source of electrical, mechanical, hydraulic, pneumatic, chemical, thermal or other energy, including stored and residual energy.

Capable of being locked out

An isolating device with a hasp or built in locking mechanism, or one lockable without dismantling or permanently altering it.

Lockout device

A device using a positive means such as a keyed or combination lock to hold an isolating device in a safe position.

Tagout device

A prominent warning device fastened to an isolating device. It warns; it does not physically restrain.

Servicing and maintenance

Constructing, installing, setting up, adjusting, inspecting, modifying and maintaining equipment, including lubrication, cleaning and unjamming. Sanitation falls inside this.
