SAFETY LOCKOUT.

Lockout-tagout (LOTO) or lock and tag is a safety procedure which is used in industry and research settings to ensure that dangerous machines are properly shut off and not started up again prior to the completion of maintenance or servicing work. It requires that hazardous power sources be "isolated and rendered inoperative" before any repair procedure is started. "Lock and tag" works in conjunction with a lock usually locking the device or the power source with the hasp, and placing it in such a position that no hazardous power sources can be turned on. The procedure requires that a tag be affixed to the locked device indicating that it should not be turned on.                                        

Disconnecting or making safe the equipment involves the removal of all energy sources and is known as isolation. The steps necessary to isolate equipment are often documented in an isolation procedure or a lockout tagout procedure. The isolation procedure generally includes the following tasks:

1. Identify the energy source(s)
2. Isolate the energy source(s)
3. Lock and Tag the energy source(s)
4. Prove that the equipment isolation is effective.

The locking and tagging of the isolation point lets others know not to de-isolate the device.

Modern machinery can contain many hazards to workers, from things like electrical, mechanical, pneumatic or hydraulic sources.

For example a typical industrial machine may contain things like hot fluids, moving presses, blades, propellers, electrical heaters, conveyor belts with pinch points, moving chains, ultraviolet light, etc.

The Five Security Rules

According to the European standard EN 50110-1, the security procedure before working on electric equipment comprises the following five steps (clause 6.2 Dead working):

1. disconnect completely;
2. secure against re-connection;
3. verify that the installation is dead;
4. carry out earthing and short-circuiting; and
5. provide protection against adjacent live parts.

PREVENTION IS BETTER THAN CURE...........
