Maintenance Responsibility
Proper maintenance is essential to safety. If you are a maintenance worker, you must
make safety a priority to effectively repair and maintain equipment.
Before removing, adjusting, or replacing parts on a machine, remember to turn off all
electric supplies and all accessory equipment at the machine, and disconnect and
lockout electrical and pneumatic power. Attach warning tags to the disconnect switch
and air shutoff valve.
When you need to perform maintenance or repair work on a temperature control unit
above floor level, use a solid platform or a hydraulic elevator. If there is a
permanently installed catwalk on your temperature control unit, use it. The work
platform should have secure footing and a place for tools and parts.
DO NOT
climb
on the temperature control unit, machines, or work from ladders.
If you need to repair a large component, use appropriate handling equipment. Before
you use handling equipment (portable “A” frames, electric boom trucks, fork trucks,
overhead cranes) be sure the load does not exceed the capacity of the handling
equipment or cause it to become unstable.
Carefully test the condition of lifting cables, chains, ropes, slings, and hooks before
using them to lift a load.
Be sure that all non-current carrying parts are correctly connected to earth ground
with an electrical conductor that complies with current codes. Install in accordance
with national and local codes.
When you have completed the repair or maintenance procedure, check your work and
remove your tools, rigging, and handling equipment.
Do not restore power to the temperature control unit until all persons are clear of the
area.
DO NOT
start and run the temperature control unit until you are sure all parts
are functioning correctly.
BEFORE
you turn the temperature control unit over to the operator for production,
verify all enclosure panels, guards and safety devices are in place and functioning
properly.
