SOPs Required
: The oven manufacturer cannot anticipate all baking applications or
processes that this oven may be used for. Specific, written SOPs are required for each
application the oven is used for at your site. These must be written by someone:
o Who is familiar with your site.
o Who is knowledgeable about each application or process the oven will be used for.
o Who knows the safety requirements applicable to your hazardous location and the
oven explosion protection systems.
•
SOP Language:
SOPs must be written and available to all operators in a language they
understand.
•
Competency : Oven operators must be competent to work in your hazardous location
type.
•
Material Properties
: The authors of your site SOPs and all oven operators must be
knowledgeable of the chemical and physical properties of any potentially explosive or
flammable materials being extracted or outgassed in the oven or any such materials
present in the hazardous classified location. This includes the auto-ignition temperature of
all substances used in your application.
•
Approved Substances Only: Oven operators and SOP authors must verify that only
approved hazardous substances will be placed in the oven chamber. These substances can
only belong to the hazardous materials groups described in the Installation chapter
11T11T11T
Allowed Hazardous Materials and Temperatures
11T11T11T
entry in this manual. See page 27.
•
Toxicity and Other Hazards : The oven operators and SOP authors must also know the
potential toxicity and other health hazards associated with solvents or other volatiles used
in your baking application. The oven does not safeguard against toxicity hazards.
•
PPE
: Oven operators and other personnel in the workspace must be trained to utilize
appropriate PPE for applicable toxicity, explosion, and flammability hazards.

SPHYXIATION
H
AZARD
Gas Nitrogen used in the purge and pressurize process or for backfilling the oven chamber can
create a significant asphyxiation hazard by crowding out oxygen in the room atmosphere. The
onset of asphyxiation can be difficult to detect until personnel lose consciousness or suffer
cognitive impairment.
•
The workspace ventilation system must provide a minimum of 6 air changes per
minute . This helps protect the operator in the event of a gas system leak or if several
backfilled ovens are opened in a short period, releasing a large, combined volume of inert
gas.
