GUIDE TO GOOD PRACTICES FOR

LOCKOUT AND TAGOUT

1. INTRODUCTION

This Guide to Good Practices is written to enhance understanding of, and provide direction

for, Lockouts and Tagouts, Chapter IX of Department of Energy (DOE) Order 5480.19,

"Conduct of Operations Requirements for DOE Facilities." The practices in this guide

should be considered when planning or reviewing lockout and tagout programs. Employers

at DOE facilities are advised to adopt procedures that meet the intent of 29 CFR (Code of

Federal Regulations), Parts 1910 and 1926 (OSHA) and DOE Order 5480.19.

DOE Order 5480.19 and this Guide to Good Practices provide a set of guidelines and good

practices for lockout/tagout from an operational standpoint. However, employers should be

aware that there are further details in other sources (e.g., OSHA) which deal more

specifically to lockout/tagout requirements from a personal safety standpoint. Employers

should refer to these other sources for additional insights to requirements and good practices

for the implementation of lockout and tagout programs at their facilities. If conflicts arise

between OSHA and DOE Order 5480.19 or this Guide, OSHA shall take precedence.

Public Law 91-596, dated December 29, 1970, established OSHA, which had as its main

purpose to ensure "so far as possible every working man and woman in the Nation safe and

healthful working conditions." As part of this effort in the late 1980s, OSHA reviewed

materials from many different sources to gather information on accidents that were caused

by failure to properly lockout and tagout hazardous energy sources. As a result of the

reviews, OSHA began to establish standards dealing with lockout/tagout of hazardous

energy sources.

The first standard became effective in January 1990. Standard 29 CFR 1910.147, "The

control of hazardous energy (lockout/tagout)," deals with servicing and maintenance of

machinery and equipment. This standard was followed in December 1990 by 29 CFR

1910.333, "Safety-Related Work Practices," which addresses exposure to electrical hazards

from work on, near, or with conductors. In May 1994, 29 CFR 1910.269, "Electric power

generation, transmission, and distribution," became effective and established locking and

tagging procedures for the deenergization of electric energy sources used for purposes of

generation, transmission, and distribution, as well as equivalent installations of industrial
