 HOW CAN I IMPLEMENT THE LOTO (Lock-Out, Tag-out) FOR ELECTRICAL WORK SAFETY?

Introduction

This document provides a way to prevent safety accidents using the Lockout Tagout (LOTO) procedure during electrical work Failure to perform LOTO during installation, inspection, and maintenance of electrical equipment may result in electric shock and power failure, so LOTO procedures must be followed for safe electrical work. The LOTO procedure consists of nine steps, each of which presents a specific method for safe operation

Key Contents

1. The importance of LOTO work

The importance of LOTO work is highlighted as the number of workplaces and associated personnel increases during electrical work

Accidents that occur during electrical work are often caused by communication errors and arbitrary manipulation, so the person responsible for the work should be careful when LOTO is released

The LOTO procedure consists of nine steps

Step 0: Staff training and energy control procedures required before LOTO is performed

Step 1: In case of equipment/machine interruption, the relevant personnel are notified

Step 2: Identify work procedures and hazards, identify energy types, sizes, hazards, control methods, etc.

Step 3: Installation/machine stop: Use the method of pressing the STOP button, turning off the switch, closing the valve, etc.

Step 4: Isolation from Energy Source: Energy Isolation Unit Used, ON/OFF and STOP buttons are not appropriate

Step 5: Apply LOTO Device: Use Lockout and Tagout

Step 6: Check residual energy: Remove residual energy from the capacitor, spring, etc

Step 7: Check isolation: Check isolation when operating the facility, using the ON button or other controls

Step 8: Installation restart: Work area clean-up, check the neutral position of all controls, and notify the operator of completion after removing the LOTO device
