Completing the Lockout/Tagout

Completing the Lockout/Tagout
Before affected employees can reenter the area, the authorized person must:

Make sure tools, spare parts, and debris are removed
Make sure parts, especially safety parts are correctly reinstalled
Remove locks and tags from energy isolation points
Re-energize equipment
Inform affected employees that they can return to work
Lock and Tag Requirements
Locks secure energy isolation points so equipment can’t be energized. Tags draw attention to the fact that the equipment is locked out. Tags should always be used with locks. Never remove locks or tags that you did not install. Locks must withstand all work conditions. Tags must be legible and have warnings like “do not start,” “do not energize” or “do not operate.” The tag’s fastener should be made of non-reusable material that can withstand at least 50 lbs., usually a nylon zip tie. Attach locks and tags to energy isolating devices securely.

Groups and Shift Changes
When a group is working on a piece of equipment, special measures must be taken. During a group lockout procedure, designate one authorized person to oversee safety. Each authorized worker must have locks for his or her individual job. A group lockbox which holds keys helps avoid confusion. Take special care during shift changes. Outgoing and incoming authorized employees must coordinate a smooth exchange of lockout/tagout devices

Summary
The Occupational Health and Safety Administration estimates that lockout/tagout systems prevent 120 deaths and 50,000 injuries every year. It can’t be emphasized enough how important it is to follow lockout/tagout procedures. Know what part you play and never tamper with locks and tags, especially when they’re being used. A person’s life and limbs could depend on it.
