Lockout/Tagout is required by the Occupational Safety and Health Administration, or OSHA for short. The Code of Federal Regulation (CFR) 1910.147 titled "Control of Hazardous Energy Lockout/Tagout," describes the OSHA lockout/tagout regulations.

This rule includes information on:

• The application of procedures
  
• Servicing and maintenance operations
  
• Requirements and inspections
  
• Removal of locks and tags and other related issues

OSHA requires employers to provide adequate training to ensure employees understand the purpose and function of the lockout/tagout program. And that employees possess the knowledge and skills required for the safe application, usage, and removal of locks and tags.
