LOTO was #4 on OSHA's Top 10 most-cited standards in FY2025 with 2,177 citations — and at a steel plant where a single rolling mill drive can have 12 simultaneous energy sources (electrical, hydraulic, pneumatic, thermal, gravitational, mechanical), a missing or inadequate written procedure doesn't just create a citation. It creates a fatality. The OSHA standard is unambiguous: every machine requiring energy isolation must have its own written machine-specific procedure. A single generic procedure covering all equipment is a willful violation. Annual inspections of every procedure, performed by an authorized employee other than the one using it, must be documented and certified. And every authorized employee must have documented training. This free LOTO procedure template — PSSR-linked and CMMS-integrated through Oxmaint — gives your steel plant machine-specific procedures for every major asset type, with built-in energy isolation step sequences, verification fields, group lockout protocols, and annual audit certification records that satisfy every element of 29 CFR 1910.147.

VERTICAL STEP FLOW with alternating colorsOSHA 1910.147 REQUIRED LOTO PROCEDURE SEQUENCE — STEEL PLANT STANDARD
01
Notify Affected Employees
Inform all affected workers that the equipment will be shut down and locked out. Log names and time of notification in Oxmaint work order.
02
Review Written Procedure
Authorized employee reviews the machine-specific LOTO procedure in Oxmaint mobile — identifies all energy sources, isolation points, and verification methods.
03
Shut Down the Equipment
Normal shutdown sequence per operating procedure. All moving parts at rest. Controls returned to neutral/off position.
04
Isolate All Energy Sources
Operate all isolation devices — breakers, valves, disconnects — to the OFF/CLOSED/OPEN position per the written procedure sequence. No steps skipped.
05
Apply LOTO Devices
Each authorized employee applies their own personal padlock to every isolation point hasp. Each worker's lock is unique — no shared locks. Tags applied with worker ID.
06
Release / Restrain Stored Energy
Bleed hydraulic/pneumatic lines to zero. Block gravity-loaded components. Allow thermal dissipation. Release spring tension. Document method used per energy type in procedure.
07
Verify Zero Energy — The "Try" Step
CRITICAL — most-cited gap. Attempt to start or energize the machine. Press start button. Test circuits. Verify no movement. Return controls to OFF. Document verification method and result.
08
Perform Authorized Work — Document Closure
Work begins. On completion: inspect for tools/personnel clear, remove locks in reverse order per procedure, notify affected employees, verify safe restart. Close LOTO record in Oxmaint.

Oxmaint sends inspection summary notification to all employees linked to the procedure record
"We had 34 rolling mill assets with no individual written LOTO procedures — just a generic plant-wide form that OSHA called out as a willful violation during our last inspection. After deploying Oxmaint's LOTO library, every machine has its own procedure with the specific energy isolation sequence, stored energy release method, and verification step. Annual inspections are auto-scheduled in the CMMS, and the inspector can't close the work order without the certification fields completed. We went from a $68,000 citation to zero LOTO findings in the next inspection."

Frequently Asked Questions
Q1 Does OSHA 1910.147 require a separate written procedure for every machine at a steel plant?
Yes — 1910.147(c)(4) requires machine-specific written procedures for each piece of equipment where unexpected energization could cause injury. A single generic LOTO procedure covering all equipment is explicitly cited as a willful violation. Steel plants with 30 or more distinct machines requiring energy isolation need 30 or more individual written procedures in their LOTO library.
Q2 What is the "try step" and why is it the most commonly cited LOTO gap?
The try step — Step 7 in the 8-step sequence — requires the authorized employee to attempt to start or energize the machine after locks are applied, confirming that the isolation is effective. OSHA cites this as one of the most frequently skipped steps, because workers assume the locks are effective without verifying. In Oxmaint, the try-step verification is a mandatory checklist field — the LOTO work order cannot close without a documented zero-energy confirmation.
Q3 How does group lockout work at a steel plant with multiple authorized employees?
Under 1910.147(f)(3), when two or more workers are servicing the same equipment, each must apply their own personal lock to a group hasp device. The equipment cannot be re-energized until every worker removes their own lock — no supervisor can remove another worker's lock. In Oxmaint, group LOTO work orders track each individual lock application and removal, creating a complete record of every participant's isolation confirmation.
Q4 What must a 1910.147 annual LOTO inspection certification include?
Per 1910.147(c)(6)(ii), the certification must identify: (1) the machine or equipment on which the procedure was inspected, (2) the date of inspection, (3) the employees included in the inspection, and (4) the name of the authorized person performing the inspection. The inspection must be performed by an authorized employee other than the one who uses the procedure, and must include a live demonstration of the procedure with each authorized employee.
Q5 Does LOTO apply to crane maintenance in a steel plant?
Yes — crane maintenance is covered by both OSHA 1910.147 (general industry LOTO) and 1910.179 (cranes and hoists), which specifically requires crane switches to be open and locked before any preventive maintenance or repair begins. Oxmaint's LOTO library includes pre-built crane procedures that satisfy both standards simultaneously, with pendant control isolation, main switch lockout, and suspended load blocking steps as mandatory checklist items.
Q6 How does Oxmaint handle LOTO for equipment with multiple energy sources?
Oxmaint's machine-specific LOTO procedure records list every energy source on the equipment independently — with the isolation device location, isolation method, stored energy release requirement, and verification method for each source as separate checklist items. The procedure cannot be certified as complete until every individual energy source on the list has been marked isolated and verified, preventing the "missed energy source" failure mode that causes most steel plant LOTO incidents.
Q7 How should thermal energy be controlled during EAF or furnace maintenance?
For thermal energy isolation on EAF furnaces and reheating furnaces, the LOTO procedure must close all gas and oxygen supply valves, lock out combustion air blowers and burner controls, and specify a minimum cool-down time or temperature threshold before access is permitted. Verification requires a contact thermometer reading below the safe-entry temperature — typically below 50°C for body contact surfaces — documented in the LOTO completion record.
Q8 Can Oxmaint link LOTO procedures to PSSR requirements for equipment modifications?
Yes — when a modification triggers a PSSR under OSHA 1910.119(i), Oxmaint's PSSR workflow Area 2 (procedures) requires confirmation that the LOTO procedure for every affected machine has been updated to reflect the modification scope. The PSSR sign-off requires the current LOTO procedure document version number, creating a direct link between the MOC process and the LOTO library that prevents workers from using outdated energy isolation procedures on modified equipment.
