2-4.3
Heat processing equipment must always be used with caution. Proper equipment
such as insulated gloves, safety goggles and tongs should be used for reaching
into hot equipment. Proper supervision is essential and only trained personnel
should be allowed to operate the furnace.
Always remember you are working with elevated temperatures.
-Do not touch surfaces - they could be hot and burns could result.
-Do not breathe hot furnace air. Heated air could burn lungs.
-Many items become dangerous when heat is applied. Explosion or fire
could result. Make sure you know what you are putting in the furnace can
be heated safely at the furnace operating temperature.
2-4.4
Furnace heating elements operate at line voltage. Do not touch them or allow
work to come in contact with the heating elements. A door interlock is provided to
disconnect power from heating elements when the door is opened. Do not defeat
the operation of this door interlock.
2-5.5
Disconnect power before servicing equipment. Furnaces operate under high
voltage and electrical shock is possible. Proper panel lockout procedures should
be followed.
2-4.6
Disconnect other sources of potential energy such as compressed air, before
servicing. Proper lockout procedures should be followed.
2-4.7
Do not operate mechanical or electrical equipment with guards removed.
Operating with guards removed could result in bodily injury.
2-4.8
Furnaces with vertical lift doors or top loading doors must be blocked open before
passing beneath them. A falling door may cause bodily injury. A safety pin, latch or
support strut is provided for this purpose.
2-5 MAINTENANCE AND INSPECTION
2-5.1
Regularly scheduled inspection and maintenance of all safety devices shall be
performed by user. Failure to do this may result not only in fire or explosion
damage, but also contribute to accidental shutdowns and loss of production. See
Section 7 - Maintenance and Appendix C - Minimum Periodic Maintenance Report.
2-5.2
Regularly scheduled inspection of the furnace interior, heat chamber and ductwork
shall be performed by user to determine need for cleaning and repair. Failure to do
this may result in internal fires or component failure resulting in furnace damage
and loss of production.
2-5.3
It shall be the sole responsibility of the user to establish, schedule and enforce the
frequency of and the extent of the inspection/maintenance program (as well as the
corrective action to be taken) because only the user can know what the actual
operating conditions are. Contact your insurance authority, Factory Mutual or the
National Fire Protection Association, whose addresses are listed in Appendix B, for
more information on inspection/maintenance programs.
2-5.4
It shall be the responsibility of the end user to determine that current processing is
within the scope of the original design of the equipment.
