Lockout/Tagout Procedure
This lockout/tagout procedure is designed to protect all employees from injuries caused by the
unexpected energizing or startup of the machine, or the release of stored energy during service
and maintenance.
This is accomplished with energy isolating devices that prevent the transmission or release of
energy. An energy source is any source of electrical, mechanical, hydraulic, pneumatic,
chemical, thermal, or other energy source that could cause injury to personnel.
A lockout device utilizes a lock and key to hold an energy isolating device in the safe position
and prevents the machine from being energized. A tagout device is a prominent warning device
that can be securely attached to the machine warning personnel not to operate the energy isolating
device. This procedure requires the combination of a lockout device and a tagout device.
The lockout/tagout procedure applies to any employee who operates and/or performs service or
maintenance on the machine. Before any maintenance or repairs are performed, the machine
shall be isolated, and rendered inoperative as follows.
1. Shut down the machine by pressing the stop button, and open the high pressure cutting
water valve to bleed the water and hydraulic pressure from the system.
2. Disconnect, lockout and tag the main, customer supplied, power source.
3. Lockout and tag the circuit breaker/disconnect on the electrical enclosure door.
4. Close, lockout and tag the manual shutoff valves for all service connections: cutting water
in, cooling water in and out, and air.
Warning Labels
Warning labels are posted on the machine to indicate potential hazards. The operator and service
personnel shall pay particular attention to these warning labels. Table 1-2 describes the necessary
precautions and provides the part number required to order replacement labels.
