– Area that is close to heat sources.
– Area that produces substances such as sulfuric
gas, chlorine gas, acid, and alkali. It may cause
corrosion of the pipings and brazed joints.
– Area that can cause leakage of combustible
gas and suspension of carbon fibers,
flammable dust, or volatile flammables.
– Area where refrigerant leaks and settles.
– Area where animals may urinate on the
product. Ammonia may be generated.
