Requirements for Handling Corrosive Gases

Requirements for Handling Corrosive Gases

The room must be free from corrosive gases, such as SO2, H2S, and NH3. Table 2-15 lists the requirements for corrosive gas concentrations. For details, see the indoor requirements specified in the GR-63 standard.
Table 2-15 Requirements for corrosive gas concentrations

Chemically Active Substance

≤ 50

H2S

≤ 500

Cl2

≤ 5

Take the following measures to ensure that the preceding requirements can be met:
  • Avoid constructing the equipment room near a place where there is a high concentration of corrosive gases, such as a chemical plant.
  • Ensure the air intake vent of the room is always upwind of the pollution source, and is far away from any sewers.
  • Use environmental protection decoration materials. For example, use the Polyethylene Foam (PEF) to replace the rubber and plastic foam.
  • Do not place batteries together.
  • Monitor the corrosive gas concentrations regularly.
