Management must develop, document, and make sure employees use specific written LOTO procedures to control potentially hazardous energy.
The employer doesn't need to develop and use a written LOTO procedure for servicing or maintenance on a particular machine or equipment, but only when all of the following eight elements exist:
If the employer can't meet the above exception criteria, written LOTO procedures must be developed and used. The procedures for equipment with one or more sources of energy must outline the scope, purpose, authorization, rules and techniques that the employer will use to control hazardous energy. The scope might be limited to a single or group of similar pieces of equipment or machinery. The purpose of the procedures is to ensure the unexpected energization/startup or shutdown does not occur during servicing or maintenance activities. The responsible manager authorizes the procedures and ensures specific rules/techniques are listed within the procedures.
The procedures must state the means to be used to enforce compliance. Typically, this requirement is met by stating the procedure is mandatory and may result in disciplinary action if not followed.
At a minimum, the procedures must include the points listed below.
This is very important to remember: if an energy isolating device is not capable of being locked out, the employer's energy control program must use a tagout system.
If an energy isolating device is capable of being locked out, the employer must use a lockout system unless the employer can demonstrate that the tagout system will provide full employee protection. The employer may choose to use a tagout system as long as the requirements for additional training and periodic inspections are met. You'll read more about "full employee protection" in a later module.
There are a couple requirements for the use of tagout devices when lockout devices aren't capable of being used. Below is a list:
The employer must demonstrate the protection achieved using the tagout program is equivalent to the level of safety obtained by using a lockout program. So, how do they do it? They must comply with all tagout-related provisions and also use additional safety measures that provide a level of safety equivalent to that obtained by using lockout.
All new machines and equipment, or all machines and equipment that undergo major repair, renovations or modification, must be equipped with energy-isolating devices capable of accepting a lockout device.
After January 2, 1990, whenever replacement or major repair, renovation or modification of a machine or equipment is performed, and whenever new machines or equipment are installed, energy isolating devices for such machine(s) or equipment must be designed to accept a lockout device.
