PROPER OVEN APPLICATION
2-1
GENERAL
2-1.1
W hile ovens are extremely versatile, they are usually purchased with a specific
application in mind. If your process has changed significantly or if you should have
reason to doubt that a specific application is a proper use of the equipment, consult
the factory before proceeding.
2-1.2
Explanatory Material (Annex A1.1) of the National Fire Protection Association
Publication 86 "Standard for Ovens and Furnaces" states; in part:
"Explosions and fires in fuel-fired and electric heat utilization equipment constitute
a loss potential in life, property and production.

Most failures can be traced back to human error. The most significant failures
include inadequate training of operators, lack of proper maintenance, and improper
application of equipment."
2-1.3
To protect the oven, oven contents, property and personnel, a responsible person
should be in attendance during operation.
Do not operate oven unattended
.
Special attention must be paid to:
-Setting correct temperature.
-Placing flamm able solvents in oven; these ovens are not designed for that
purpose.
-Placing combustibles in an oven that does not have adequate fire protection.
-Allowing the product to remain in the oven too long, thereby encouraging
combustion.
-Using an oven for a process other than that for which it was designed.

2-2.2
It shall be the user's responsibility to insure that flammable solvents are not placed
in the oven and the operating temperature does not exceed the m aximum rated
temperature of the oven.
