Certain portions of a commercial building may present greater risks due to the concentration of electrical systems or proximity to water sources. You should manage these places with extreme caution, and only authorized workers should access them. Additionally, use signage and barriers to alert people to the potential dangers.

Lockout/Tagout (LOTO) Procedures

What is Lockout/Tagout?

Lockout/tagout (LOTO) is a safety practice that ensures electrical systems are properly turned off and cannot be restarted until maintenance or repair work is completed. This eliminates accidental energization of electrical equipment, which could result in significant harm.

Steps to Implement LOTO Effectively

To implement LOTO effectively:

1. Identify all energy sources: Make sure all electrical energy sources are located and isolated.
2. Shut down equipment: Power off all machinery and equipment.
3. Lockout energy sources: Apply locks to energy-isolating devices.
4. Tagout equipment: Attach tags to indicate that the equipment is under maintenance.
5. Verify isolation: Ensure that the equipment cannot be re-energized.

Common Mistakes to Avoid

Common mistakes in LOTO procedures include:

• Failing to identify all energy sources: Missing even one source can be dangerous.
• Improper tagging: Tags should be clear and specific to prevent misunderstandings.
• Neglecting to verify isolation: Always double-check that the equipment is properly isolated before beginning work.

Electrical Testing and Verification

Testing Before and After Repairs

Electrical testing is an important step before and after repairs. Before beginning the repair, testing can assist in determining the exact problem and guarantee that the equipment is safe to operate on. Following repairs, testing confirms that the repairs were effective and that the system is safe to use.
