0.4.2.2 Fire Safety During Maintenance and
Repair
Observe all regulations on fire safety. Sources for
fires include, but are not limited to the following:
– Sparks from grinding.
– Flames and molten metal from welding or
torching.
– Electrical arcing.
– Spontaneous combustion.
– Smoking.
Before starting any work take the following steps to
prevent a fire hazard:
– Properly dispose of rags with combustible
material to avoid spontaneous combustion.
– Move flammable materials 10 m (33 ft) or
more away from any fire hazard.
– Clean up all debris.
– Clean up all oil spills and leaks.
– Remove any source of flammable gases,
liquids or solids.
– Use proper electrical grounding
techniques for welding.
– Provide adequate fire extinguishing
equipment; inspect such fire equipment
regularly.
– Arrange for qualified personnel to guard
against fire while welding, cutting, or
heating operations are being performed, as
well as a sufficient period of time after the
work is completed.
– Protect yourself and others from sparks
with proper personal protective equipment
and clothing.
0.4.2.3 Preventive Maintenance
Preventive maintenance will both increase safety
and be economically beneficial. It is more safe and
economical to replace a worn part during a
scheduled shut-down than to repair a broken device
in the middle of a production cycle. A machine or
device that is not in proper condition, and that has
been left without regular maintenance and
inspections, is a safety risk to its user. For instance,
without lubrication a bearing may fail, bringing a
production line down. Furthermore, the hot bearing
may present a fire hazard or cause skin burns.
Some preventive maintenance suggestions for a
machine include:
– Observe the maintenance and lubrication
instructions of the machine and equipment
suppliers.
– Keep the machine and surrounding area
clean and orderly.
– Monitor the vibration levels of the
machine to help detect loose or worn parts
or impending bearing failure.
– Monitor the power consumption of motors
to help detect early failures.
– Repair all leaks as soon as possible to
prevent more serious conditions. Repair
fuel leaks immediately.
– Monitor the condition of pipes and tubes
enclosed in ducts; repairing possible leaks.
0.4.2.4 Confined Spaces
A confined space means a space that:
– is large enough and so configured that a
person can enter and perform assigned
work; and
– has limited or restricted means for entry or
exit (for example, the crushing cavity,
tanks, vessels, silos, storage bins, hoppers,
vaults, and pits are spaces that may have
limited means of entry); and
– is not designed for continuous employee
occupancy.
Certain confined spaces may require an entry
permit program to allow entry. Be sure that all
applicable procedures are followed. If you have
questions contact your Crushing Plant supervisor
for more information.
