Flammable Area Classification

Flammable Area Classification is the process of categorizing areas where flammable gases, vapors, or dusts are present, allowing for the implementation of safety measures based on the frequency and duration of their presence. This process is essential for minimizing ignition risks in hazardous environments.

Key Elements of Flammable Area Classification:

  • Classification System:
    • Classes – Based on the type of flammable material (e.g., gases, dusts, fibers).
    • Zones – Based on the likelihood of a flammable atmosphere forming.
  • Zone Definitions:
    • Zone 0 – Explosive atmosphere is present continuously or for extended periods.
    • Zone 1 – Explosive atmosphere is likely to occur during normal operations.
    • Zone 2 – Explosive atmosphere is unlikely in normal operations but may occur briefly.
  • Industries Where It’s Applied:
    • Chemical processing plants – Identifying hazardous areas around storage tanks and processing equipment.
    • Oil & gas refineries – Classifying zones where flammable gas leaks could occur.
    • Paint manufacturing – Identifying hazardous areas around spray booths and mixing stations.
