LOCK OUT

When a system emits some energy, that complete system must be given care in all the matters including the space provided, ventilation, tidiness, environment and its surroundings. Lock out is a term used in Canadian standards which is for the control of Hazardous Energy. Lock out is the place at which lock is placed at the system so that the system is completely isolated with no escaping energy. This energy is known for hazardous energy. If the lock out is placed for an equipment or for a system, no energy escapes from it and is completely in safe mode. The locking device may be of any type but the only reason that is concerned here is the energy allowance.

TAG OUT

After lock out process is complete, tag out is done. Tag out is a labelling process that is used as an indicator or a measure to the user following the instructions for the lock out. The Tag out may include the reason of the lock out like repair or maintenance, time period of the lock out, time at which the lockout has been placed, the name of the authorized person who fetched and attached the lock and tag to the system.

Lock out and Tag out is used primarily for safety purposes. If the system working is defective and must be reviewed it will be locked out and tagged out to prevent the use of the system. This is also to protect the workers working at that system and to prevent the failure of the system.

There must be separate written documents for the lock out and tag out of any system or any equipment. The document must be paper work and must provide all the reasons like the exact reason for isolation, how the lock out devices are installed, when the lock out devices are installed and where the lock out devices are installed. It must also contain the process how the equipment or system will be de-energized and controlled, and again put the system in to work. A Separate organization will be employed to look after all the procedures.
