Lotto Procedure Preparation
Systematic Documentation of Energy InsulationPreparing a specific LOTO procedure for each piece of equipment is a fundamental requirement of OSHA 1910.147, and improperly prepared procedures hold the employer liable for worker injuries. At AES Innovation, we prepare detailed, OSHA-compliant LOTO procedures for all equipment in your facility.
Lottery Procedure Preparation:
Initial Stages and Inventory Creation
LOTO procedure preparation, step-by-step, involves meticulously documenting the insulation process during maintenance and repair of equipment containing electrical, mechanical, hydraulic, and thermal energy sources.
The LOTO procedure preparation process begins step-by-step with, first, taking inventory of all the equipment at the facility:
Creating an Equipment Inventory: All Welded Devices
All equipment in the facility is classified according to its energy type (electric, gas, steam, compressed air, hydraulic). The name, location, energy source, and year of manufacture of each piece of equipment are recorded. Missing or forgotten equipment may result in LOTO non-compliance.
Energy Resources Mapping: Creating Flowcharts
The energy sources of each piece of equipment are graphically mapped (flowcharts, electrical diagrams, P&ID). Which switch, valve, or device can cut off the power is clearly indicated.
Identifying Stored Energy Sources
Sources that store energy even after being switched off, such as capacitors, accumulators, pressure tanks, and spring mechanisms, are identified. The safe discharge of the stored energy must be described in the procedure.
Energy Control Documentation:
Content of the Written ProcedureEnergy control documentation according to OSHA standards requires that each LOTO procedure document include the following information:
- Equipment name and locationCookies
- Energy sources: Detailed explanation of electricity, gas, etc.
- Energy checkpointsWhich switches/valves will be closed (e.g., “Main breaker, Circuit 7, Valve A-2”)?
- Isolation stepsThe procedures to be followed for each energy source (e.g., “1. Turn off the main unit. 2. Wait 5 seconds. 3. Click the discharge button 3 times”)
- Stored energy release: Discharging method for capacitors, accumulators, etc.
- Verification procedureTest equipment and control method
- Re-energizingEnergy restoration sequence and warnings.
- Hazard warningsRisks of unexpected energy release.
- Authorized person: The engineer who prepared and revised the procedure.
- Revision dateProcedure drafting and update dates
- Electrical controlVerify 0V using a voltmeter or multimeter.
- Mechanical control: Confirming the equipment's unresponsiveness by operating the buttons/control sticks.
- Pressurized systemsVerifying that the pressure is 0 bar using a manometer.
- Signature by the testerThe person conducting the check assumes responsibility by signing the document.
Verification Test Procedure:
Zero Energy Certification: The verification test procedure for zero energy involves testing that the energy sources are completely isolated.
Re-energizing Steps:
Secure Retrieval ProcedureThe re-energization steps are the procedure for safely returning equipment to operation after maintenance is complete.
- Isolation verification: To ensure maintenance is complete.
- Stored energy control: Ensure that the emptying is complete.
- Area cleaning: Checking that no one remains around the equipment.
- A warning is issued.: "Equipment is being energized" warning
- Lock/tag removal: Remove the locks one by one
- Return to normal operationTurn the switches on and verify that the system is functioning.
