Tagouts If a machine or item of equipment has a hazardous condition, a way to inform people is to place a tag on it that clearly identifies the hazard. That way, someone does not inadvertently use or work on the machine or item without knowing the danger. When working on electrical systems and equipment, workers need to use both lockout and tagout procedures concurrently. In addition, if equipment always has a known hazard, it may need a permanent label identifying the hazard. 

Lockout and Tagout Procedures During setup, maintenance, or cleaning, workers must lock out and tag out a machine before beginning service. This will prevent anyone from activating it inadvertently or while someone else expects it to be de-energized.

High-powered microwave equipment must be grounded to reduce electrical hazards. Metal objects may build a charge from the electrical field of the microwave equipment. Interlocks on doors protect access to hazardous microwave locations. The interlocks prevent unauthorized access to hazardous microwave locations. The interlocks require frequent inspections and testing to ensure they are working properly. Lockout and tagout procedures are important for servicing of microwave equipment. 

The workers must reduce the energy level and apply lockout and tagout procedures. 

Another hazard of confined spaces is a pressurized atmosphere. When someone opens a pressurized container, the door may fly open causing injury. Confined spaces may contain moving parts that can cause injury. The moving parts may need to follow lockout and tagout procedures and other procedures that remove or restrain stored energy. There may also be hazards from electrical equipment or dangers from ducts, pipes, or drains that connect to sources of hazardous materials. 

Lockout and tagout procedures are special procedures for working on normally energized equipment. The energy may involve electricity, steam, mechanical, or other forms of power or energy. Employers must ensure that any individual involved with a lockout/tagout procedure knows the details of the procedure. 

Those involved in work that is not part of normal operations, such as maintenance and cleaning of machines and equipment, must learn special safety techniques. Maintenance and cleaning may require removal of guards or testing machine performance. The workers may need to implement lockout and tagout procedures, but certain tasks require machine operation. These workers may have exposure to hazards during normal operations. 

Prevent energy releases. Lockout and tagout procedures and interlocks apply here.

Supportive safety procedures are utilized to ensure that there are necessary controls in place for safe maintenance and repairs that importantly includes nonroutine hazardous work. These procedures encompass rules governing lockout and tagout, confined space entry, elevated work, electrical work, etc. The committee found some minor problems in these supportive procedures and differences among the sites, especially when some of the work is done by subcontractors, who may have their own practices. 

After several fatiguing hours of work on a maintenance project, it was time to lockout and tagout the electrical power, for which a detailed procedure was in place. An employee, feeling the pressure to get the job done immediately so that production could be recommenced, chose not to follow the procedure. He was electrocuted. 

Whenever outside personnel are to be engaged in activities covered by the scope and application of the lockout/tagout procedure, the utility and the outside contractor shall inform each other of their respective lockout or tagout procedures. The utility shall ensure that their employees understand and comply with the restrictions and prohibitions of the outside contractor s energy control program. 

When outside servicing personnel are involved in activities covered by this procedure, the outside employer shall be informed about this procedure and shall inform the safety manager of its lockout or tagout procedure. If such personnel fail to foUow the procedure, they must be instructed to follow it. Subsequent failure to follow this procedure should be enforced by stem measures, up to and including removal of the personnel from the facility.

The development and implementation of safety procedures for non-routine work are required by OSHA and EPA. These specifically include hot work (such as welding), lockout or tagout, line-breaking, and confined-space entry. Other examples of non-routine work for which procedures should be developed would be excavation, electrical hot work (on energized conductors), hot-tapping (on pressurized piping), and, in some instances, personal protective equipment. 

Nomoutine work which is conducted in process areas needs to be controlled by the employer in a consistent manner. Hie hazards identified involving the wmk that is to be accomplished must be communicated to those doing the work, but also to those operating personnel whose work could affect the safety of the process. A work authorization notice or permit must have a procedure that describes the steps the maintenance supervisor, contractor representative, or other person needs to follow to obtain the necessary clearance to get the job started. The work authorization procedures need to reference and coordinate, as applicable, lockout/tagout procedures, line breaking procedures, confined space entry procedures, and hot work authorizations. This procedure also needs to provide clear steps to follow once the job is completed in order to provide closure far those that need to know the job is now completed and equipment can be returned to normal. 

The SNL ES H Manual Supplement, Lockout/Tagout Procedure for the Contro of Hazardous Energy, (SNL 1998b) prescribes lockout/tagout (LOTO) procedures during maintenance, repair, adjustments, and installation of hydraulic, pneumatic, thermal, chemical, mechanical, or electrical equipment or of systems that, if unexpectedly energized, could harm people or property.
