Step 3: Energy Control Point Identification

The third step of a lockout program is to identify all energy control points with lockout/tagout tags, labels or signs.

In Section 1910.147(C)(5)(III) ‘ENERGY SOURCE IDENTIFICATION’, OSHA requires facilities to locate and mark all electrical energy isolation points (; eg.switches, breakers and plugs).

Energy control points should be marked with permanently placed labels or tags that warn against hazardous conditions if the machine or equipment is energized.

OSHA 1910.333(e) and (f) requires that all disconnecting means show the magnitude and be legibly marked to indicate the purpose, unless located and arranged so the purpose is evident.

Additionally, ANSI Z244.1-2003 for the Control of Hazardous Energy states that all energy isolation controls, including valves, should be adequately labeled or marked. Identification shall include the following:

• Machine, equipment, process supplied
• Energy type and magnitude
