2-3 COMBUSTIBLE MATERIAL
2-3.1 Introduction of combustible materials (such as paper, cardboard or wood) into the
oven should be avoided because it might cause a fire. Do not use combustible
racks, trays, holders, spacers, etc. Periodically, clean all combustible material
from non-combustible racks, trays, holders, spacers, etc. If combustible products
must be processed in an oven, extreme care must be taken to ensure that the
operating temperature does not exceed the ignition temperature of the product.
2-3.2 Ovens containing or processing sufficient combustible materials (including
consideration for combustible drippings or deposits) to sustain a fire shall either be
located in an area where a fire would not do damage or be equipped with an
automatic fire protection system including areas in exhaust ducts that could
accumulate combustible material. Fire protection systems should be installed in
accordance with the applicable National Fire Protection Guidelines:
-Sprinkler Systems in accordance with NFPA 13
-Water Spray Systems in accordance with NFPA 15
-Carbon Dioxide Extinguishing Systems in accordance with NFPA 12
-Foam Extinguishing Systems in accordance with NFPA 11
-Dry Chemical Extinguishing Systems in accordance with NFPA 17
-Water Mist Systems in accordance with NFPA 750
The extent of protection required will depend upon the construction and
arrangement of the oven as well as the materials handled. Fixed protection, such
as automatic sprinklers or other types of fire extinguishing systems, should be
designed and installed by a qualified contractor.
2-3.3 Drip pans shall be provided to collect any combustible materials that may
accumulate beneath the product. Drip pans must be a minimum of 2" above
perforated bottom of oven work space and allow 2" clearance around the edges. A
maintenance program must be developed to remove any such accumulation before
a dangerous build up occurs. If you cannot acquire drip pans locally, contact us for
a quotation.
2-4 PERSONNEL HAZARDS
1-3.1 Heat processing equipment must always be used with caution. Proper equipment
such as insulated gloves, safety goggles and tongs should be used for loading hot
equipment. Proper supervision is essential and only trained personnel should be
allowed to operate the oven.
Always remember you are working with elevated temperatures.
-Do not touch surfaces - they could be hot and burns could result.
-Do not breathe hot oven 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 oven
can be heated safely at the oven operating temperature.
2-4.2 Disconnect power before servicing equipment by unplugging from electric outlet.
Ovens operate under high voltage and electrical shock is possible. Proper lockout
procedures should be followed.
2-4.3 Do not operate mechanical or electrical equipment with guards removed.
Operating with guards removed could result in bodily injury.
