Introduction
A lockout tagout procedure template is one of the few safety documents where the regulator has effectively written your table of contents for you. OSHA's control of hazardous energy standard, 29 CFR 1910.147, spells out what an energy control procedure must contain — and OSHA estimates that compliance with the standard prevents roughly 120 fatalities and 50,000 injuries every year. The standard also appears in OSHA's ten most frequently cited violations year after year, and the most common citation is exactly the topic of this article: failing to develop machine-specific written procedures.
This guide gives you the template structure, walks the six steps of lockout, and fills the template in for a hydraulic press so you can see what a finished, auditable LOTO procedure looks like.
What OSHA 1910.147 Actually Requires
The standard requires an energy control program with three parts: written energy control procedures, employee training, and periodic inspections. The written procedure must specifically outline the scope, purpose, authorization, rules, and techniques for controlling hazardous energy — including the steps for shutting down and isolating equipment, placing and removing lockout devices, and verifying isolation.
One narrow exception exists: a machine can be exempt from a written procedure only if it meets all eight conditions of the standard's exception — including a single energy source that is readily identifiable and isolable, complete deactivation by that single isolation, and no stored or residual energy. Very little real production equipment qualifies. Assume you need a written, machine-specific procedure unless you can document otherwise.
Key Elements of a Lockout Tagout Procedure Template
1. Machine Identification and Scope
Equipment name, asset number, location, and the specific tasks the procedure covers (die change, unjamming, blade replacement). One procedure per machine or per group of genuinely identical machines — "see maintenance department" is a citation waiting to happen.
2. Energy Source Inventory
Every energy type present with its magnitude and isolation point: electrical (480V panel disconnect D-12), hydraulic, pneumatic, mechanical, thermal, chemical, and gravity. Missed secondary energy sources — a raised ram, a charged accumulator — are the classic cause of LOTO fatalities.
3. Notification and Preparation
Who must be notified before shutdown (affected employees, supervisors), and what the authorized employee must know before starting: the energy types, their hazards, and the isolation methods. This is step one of the six-step sequence.
4. Shutdown Sequence
The normal stopping procedure for the machine, in order. Shutting down out of sequence can itself create hazards, so the template should list the exact controls in the exact order.
5. Isolation Points and Methods
Each isolation device, its location, and its safe position: disconnect switches to OFF, valves closed, lines blanked. Include a diagram or photo of each isolation point — this is the section that makes the procedure genuinely machine-specific.
6. Lock and Tag Application
Who applies devices (only authorized employees), the one-lock-one-person rule, and tag content requirements. Tags alone are permitted only where a device cannot be locked out, and then only with demonstrably equivalent protection.
7. Stored Energy Release
The steps to relieve, disconnect, restrain, or otherwise render safe all stored and residual energy: bleed hydraulic pressure, vent air lines, block raised components, allow hot surfaces to cool, discharge capacitors. If re-accumulation is possible, the procedure must require continued verification.
8. Verification of Isolation
Try the start controls with everyone clear, test with appropriate instruments, and return controls to neutral. "Try before you rely" is the single most important step in the sequence — and the one most often skipped.
9. Return to Service
Inspect the work area, confirm tools and blocks are removed, verify all personnel are clear, notify affected employees, then remove devices — each lock removed only by the person who applied it — and re-energize in the specified order.
10. Group Lockout and Shift Change Provisions
For multi-worker jobs, designate a primary authorized employee and use a group lockbox or hasp so every worker attaches a personal lock. For shift changes, define the orderly transfer of devices so protection is never interrupted between outgoing and incoming crews.
Training Levels: Authorized, Affected, and Other
The standard defines three training tiers. Authorized employees — those who perform the lockout — need training on energy types, isolation methods, and procedure execution. Affected employees — operators of the equipment being serviced — need to recognize when LOTO is in effect and understand they must never touch a lock or attempt a restart. Other employees who work in the area need awareness of the program and the prohibition on disturbing devices. Retraining is required whenever job assignments, machines, or procedures change, or when an inspection reveals deviations.
The Annual Audit Requirement
At least annually, an authorized employee other than the one using the procedure must inspect each energy control procedure — watching it performed, reviewing responsibilities with each authorized employee involved, and certifying the inspection with the machine, date, employees included, and inspector. This periodic inspection is a distinct, frequently cited obligation: a perfect written procedure with no annual audit trail is still a violation.
Worked Example: Hydraulic Press Lockout
Abbreviated to show how the template fills in:
- Machine: Hydraulic press HP-03, Bay 2. Covers die changes and any work inside the point of operation.
- Energy sources: Electrical — 480V, panel disconnect D-07. Hydraulic — system pressure plus accumulator. Gravity — ram may drift down.
- Shutdown: Complete or safely abort the current cycle, then press the stop control at the operator station.
- Isolate: Turn disconnect D-07 to OFF. Close the hydraulic supply valve V-2.
- Apply locks: Each authorized employee applies a personal lock and tag to D-07 and V-2 (hasp if multiple workers).
- Release stored energy: Bleed the accumulator via valve V-4 until the gauge reads zero. Lower the ram to its mechanical stop or install the safety block.
- Verify: Press the cycle start with all personnel clear — no response. Confirm zero on the pressure gauge. Return controls to neutral.
- Return to service: Remove tools and safety block, confirm guards are replaced and personnel clear, remove locks (each by its owner), open V-2, close D-07, and notify affected employees before the first cycle.
Step-by-Step: Building Your LOTO Procedure Library
- Inventory every machine and its energy sources. Walk the floor with maintenance — the accumulator nobody mentions is the one that matters.
- Apply the exception test honestly. Document which machines (if any) genuinely qualify; write machine-specific procedures for everything else.
- Draft from this template with photos. Photograph each isolation point with the device in the safe position.
- Validate by performing the lockout. An authorized employee follows the draft literally; every hesitation is an edit.
- Train to the three tiers and document it. Names, dates, content, and trainer for authorized, affected, and other employees.
- Schedule the annual inspections. One certified inspection per procedure per year, by someone not using that procedure at the time.
Common Mistakes to Avoid
One generic procedure for the whole plant. The absence of machine-specific procedures is the most cited element of the standard. Generic documents do not tell anyone where valve V-2 is.
Missing stored energy. Electrical disconnection is the easy part; accumulators, springs, and suspended loads are what the template's energy inventory exists to catch.
Skipping verification. Applying a lock without trying the start controls defeats the entire exercise.
Borrowed locks and shared keys. One person, one lock, one key. Supervisor removal of another worker's lock is allowed only under a strict, documented exception process.
No annual audit trail. Certified periodic inspections are mandatory. Put them on the maintenance calendar like any other PM.
