8 Emergency Operating Procedures
8.1 Lockout and Tagout
This procedure is designed to prevent injuries caused by the unexpected start-up or movement of a
machine. These procedures are to be followed every time a machine is to be cleaned,maintained,
adjusted or repaired. When used as intended, Lockout also protects personnel from energy stored
in devices such as springs, accumulators, batteries, hydraulic systems, etc.
Where the lock out and tagout symbols (Reference: Chapter 2) appear on a safety sign it indicates
that the machine must be switched off and locked out before any work is carried out.

WARNING
Never give your key to anyone else and where more than one person is working on the equipment
they must fit their lock also.
(1) Before Carrying Out Any Work on the Machine
NOTICE
Depending on the type of machine, there can still be several kinds of energy remaining after the
power is turned off. Secondary energy sources are hydraulic (fluid under pressure), pneumatic
(air under pressure), kinetic (force of moving parts) and potential (force contained in weights that
have been raised).
If, the machine will not be used for periods longer than 24 hours, the machine must be locked
out and tagged out until further use is required.
After, key off the isolator switch must remain in the “ON” position for a minimum of 20 seconds
to allow all systems to shut down properly.
