Why LOTO is Important
Picture yourself working inside a huge machine, tending to its maintenance. Suddenly the machine springs to life, powerful metal gears grinding around you, placing you in mortal danger. That is exactly the sort of terrifying scenario that lockout/tagout is meant to prevent. Lockout/tagout is a procedure to disable equipment to protect workers from either an unexpected release of energy or an accidental start-up while performing job activities.
Why LOTO is Critical Per OSHA
•average of 24 lost workdays per worker
•10% serious accidents
Outcomes ◦ Cuts
◦ Amputations
◦ Crushing injuries
◦ Fatalities

How You Keep Your Employees Safe
By establishing an energy control program consisting of:
1. Written Program
2. Energy control procedures for every type and piece of equipment
3. Employee training as appropriate
4. Annual written assessments to ensure accuracy and compliance
What is Hazardous Energy? •Electrical
•Mechanical – springs, gravity, counterbalance, pressure
•Hydraulic
•Pneumatic
•Chemical
•Thermal – result from radiation, chemical, mechanical work, electrical resistance
•Others
•During the servicing and maintenance of machines and equipment, the unexpected startup or release of stored energy could cause injury to employees.

Machine Specific Example handout
Applying lockout/tagout
Applying Lockout/Tagout: An authorized worker should notify others in the area that lockout/tagout procedures will be taking place. After listening to instructions given by the authorized worker, all unauthorized personnel should move to a safe location, away from the equipment.

Servicing and repair
Servicing and Repairing Equipment: Unauthorized personnel should stay away from the equipment while the authorized person is working on it. At this time, the equipment is at its most vulnerable to the unexpected release of hazardous energy.
Returning to operation Returning Equipment to Proper Operation:
During this phase, the authorized worker should tell others in the area when locks and tags will be removed. Workers should stay clear of the area while locks and tags are removed and the equipment is prepared for normal operation. All personnel should be informed when lockout/tagout is complete.

Lockout/ Tagout Restarting Equipment
Inspect machine/equipment and make sure:
All tools and rags are removed
Machine fully reassembled
Guards and safety devices are in place
Verify that controls are in “neutral” position
Notify all affected employees, and make sure they are safely positioned
Remove lockout device and restart equipment
Lockout Locks & Procedures
Authorized Employees
Must have or have access to enough locks for all energy sources.
No sharing of locks/keys with other employees, contractors, etc.
The authorized employee must remove any locks they apply personally.

Shift and Personnel Changes
During shift or personnel change
Personal locks must be changed.
Employee that is leaving MUST takes off lock.
Employee starting the shift applies lock.
Equipment Protection for Extended Time
Use asset locks not individual lockout tagout equipment.
Maintenance manager or department holds keys to asset locks.
Never leave individual workers LOTO equipment on the equipment for days, weeks or months.
