What Are Lockout Tags and Why Are They Required?

Lockout tags, also called lock out tags, LOTO tags, or lockout tagout tags, are warning devices attached to energy isolating equipment (such as circuit breakers, valves, or machinery controls) to alert workers that the equipment has been locked out of service during maintenance or servicing.

Under OSHA standard 29 CFR 1910.147 (The Control of Hazardous Energy), employers are required to have an energy control program that includes written procedures, employee training, and the use of energy isolating devices, including properly labeled lockout tags. Failure to comply can result in fines of up to $15,625 per violation and, more importantly, serious injury or death.

Frequently Asked Questions About Lockout Tags

1. What are lockout tags used for?

Lockout tags are warning devices used in Lockout Tagout (LOTO) procedures to communicate that equipment has been intentionally de energized and locked out during maintenance or servicing. They identify the authorized worker who applied the lockout, the date, and the reason, preventing accidental re energization that could cause serious injury or death. OSHA requires lockout tags as part of every energy control program under 29 CFR 1910.147.

2. What is the difference between lockout and tagout?

Lockout uses a physical locking device (such as a padlock and hasp) to prevent energy isolating equipment from being operated. Tagout uses only a tag, without a physical lock, to warn workers not to operate the equipment. OSHA requires lockout whenever possible because it provides a greater level of protection. Tagout only programs are only permitted when the equipment cannot be locked out and requires additional safety measures.

3. Are lockout tags required by law?

Yes. OSHA standard 29 CFR 1910.147 requires employers with workers who service or maintain equipment to implement a written energy control program that includes lockout or tagout procedures. Lockout tags must be used as part of every LOTO procedure. Violations can result in fines up to $15,625 per violation, with repeated or willful violations up to $156,259.

4. What materials are lockout tags made from?

Lockout tags are most commonly made from vinyl (flexible and moisture resistant, best for harsh industrial environments), synthetic paper (durable, tear resistant, and writable), and card stock (economical, suited for lighter duty applications). The right material depends on the environment; vinyl is preferred where chemical exposure, moisture, or heavy wear is expected.

5. Can lockout tags be reused?

Most pre printed lockout tags are designed for single use to prevent unauthorized removal and ensure a fresh, legible tag is applied each time. Blank or write in lockout tags can be reused if they remain legible and undamaged, but best practice is to use a new tag for each lockout event. Custom durable tags (e.g., laminated or engraved) can be designed for repeated use in specific LOTO stations.

6. How do lockout tags differ from warning signs?

Warning signs are permanently affixed to equipment or locations to communicate ongoing hazards. Lockout tags are temporary, applied only during active LOTO procedures to identify that a specific piece of equipment has been intentionally de energized by a specific authorized employee. Lockout tags are personalized (they include the worker's name and date) while warning signs carry general hazard information.

7. What are color coded lockout tags and why are they used?

Color coded lockout tags use different colors to identify the type of hazard, department, shift, or employee applying the tag. For example, some facilities assign red tags to electrical hazards, blue to mechanical, and yellow to hydraulic/pneumatic systems. Color coding speeds up identification during audits and helps workers instantly recognize the type of energy being controlled.

8. What size lockout tags does Masterman's carry?

Masterman's carries lockout tags in two standard sizes: 6 inch by 3 inch (compact, for tight equipment spaces) and 11.25 inch by 3.25 inch (standard LOTO tag size, for high visibility identification). All EZ Hang Tags at Masterman's are the 11.25 x 3.25 inch size and come pre punched for quick attachment to padlocks and lockout devices.
