You are advised to ask a professional organization to
monitor the particle contaminants in the equipment room.

Corrosive
Airborne
Contaminants
l
Copper corrosion rate: less than 300 Åb/month per ANSIc/
ISAd-71.04 severity level G1.
l
Silver corrosion rate: less than 200 Åb/month per ANSIc/
ISAd-71.04 severity level G1.
l
You are advised to ask a professional organization to
monitor the corrosive airborne contaminants in the
equipment room.
l
The following is an example of initial evaluation for
environmental corrosion risks.
–
Whether the equipment room is near any sulfurous gas
emission sources, for example, porcelain factories,
rubber plants, tire factories, chemical factories, sewage
plants, power stations, paper mills, smelters,
automobile factories, coal mines, electroplating
factories, food factories, and tanneries? If yes,
environmental corrosion risks may exist.
–
Whether the equipment room is near the sea, saline,
sewer outlets, sewage treatment tanks, and industrial/
heating boilers? If yes, environmental corrosion risks
may exist.
–
Whether the equipment room was decorated in the
latest six months? If yes, environmental corrosion risks
may exist.
–
Whether batteries are stocked in the equipment room?
Whether the storage battery leaks? If yes,
environmental corrosion risks may exist.
–
Whether the equipment room is closed tightly?
Whether the room windows and doors are always
closed? If no, environmental corrosion risks may exist.
