Lockout/ Tagout Sounds Ominous!

by Glenn Miller

What is Hazardous Energy All About?

Energy sources including electrical, mechanical, hydraulic, pneumatic, chemical, thermal, or other sources in machines and equipment can be hazardous to workers. During the servicing and maintenance of machines and equipment, the unexpected startup or release of stored energy can result in serious injury or death to workers.

What are the harmful effects of hazardous energy?

Workers servicing or maintaining machines or equipment may be seriously injured or killed if hazardous energy is not properly controlled. Injuries resulting from the failure to control hazardous energy during maintenance activities can be serious or fatal! Injuries may include electrocution, burns, crushing, cutting, lacerating, amputating, or fracturing body parts, and others.

  • A steam valve is automatically turned on burning workers who are repairing a downstream connection in the piping.
  • A jammed conveyor system suddenly releases, crushing a worker who is trying to clear the jam.
  • Internal wiring on a piece of factory equipment electrically shorts, shocking worker who is repairing the equipment.

Craft workers, electricians, machine operators, and laborers are among the 3 million workers who service equipment routinely and face the greatest risk of injury. Workers injured on the job from exposure to hazardous energy lose an average of 24 workdays for recuperation.

What can be done to control hazardous energy?

Failure to control hazardous energy accounts for nearly 10 percent of the serious accidents in many industries. Proper lockout/tagout (LOTO) practices and procedures safeguard workers from hazardous energy releases. The OSHA standard for The Control of Hazardous Energy (Lockout/Tagout) (29 CFR 1910.147) for general industry outlines measures for controlling different types of hazardous energy. The LOTO standard establishes the employer’s responsibility to protect workers from hazardous energy. This includes requiring that employers have a Written LOTO Program on which they train each worker to ensure that the employees know, understand, and are able to follow the applicable provisions of the hazardous energy control procedures:

  • Those actually servicing or maintaining machines and equipment (Authorized Personnel) must know the proper lockout/tagout (LOTO) practices and procedures to safeguard workers from the release of hazardous energy. These workers must be trained in the purpose and function of the energy control program and have the knowledge and skills required for the safe application, usage and removal of the energy control devices.
  • All employees who are authorized to lockout machines or equipment and perform the service and maintenance operations need to be trained in recognition of applicable hazardous energy sources in the workplace, the type and magnitude of energy found in the workplace, and the means and methods of isolating and/or controlling the energy. Specific procedures and limitations relating to tagout systems (where they are allowed) must also be clearly understood.
  • All employees who work in an area where energy control procedure(s) are utilized (Affected Personnel) need to be instructed in the purpose and use of the energy control procedure(s), especially prohibition against attempting to restart or reenergize machines or other equipment that are locked or tagged out.
  • Retraining of all employees is required, as needed, to maintain proficiency or introduce new or changed control methods.

If you are uncertain whether or not you need a LOTO Program and/or refresher training, contact the experts.  Your life (or the life of your co-worker) may depend on it!
