Hazardous area industries are classified based on the presence of potentially explosive atmospheres due to gases, vapors, dusts, or hybrid mixtures. Here to deal with Ex compliance is a must have and immediate responsibility of all involved.
1. Oil and Gas Industry
• Gas Hazards: Methane, propane, butane, hydrogen sulfide.
• Dust Hazards: Not common.
• Hybrid Mixtures: Possible in processing plants where both gas and dust might be present.
2. Chemical and Petrochemical Industry
• Gas Hazards: Various flammable gases and vapors like ethylene, propylene, benzene.
• Dust Hazards: Not common.
• Hybrid Mixtures: Possible in certain manufacturing processes.
3. Pharmaceutical Industry
• Gas Hazards: Solvent vapors such as acetone, ethanol.
• Dust Hazards: Powdered raw materials and products.
• Hybrid Mixtures: Possible in manufacturing and mixing processes.
4. Mining Industry
• Gas Hazards: Methane, hydrogen sulfide.
• Dust Hazards: Coal dust, metal dust.
• Hybrid Mixtures: Likely in underground mining environments.
5. Food and Beverage Industry
• Gas Hazards: Carbon dioxide, ammonia (E.g in refrigeration systems).
• Dust Hazards: Flour, sugar, starch.
• Hybrid Mixtures: Possible in production areas with both gas and dust.
6. Agriculture Industry
• Gas Hazards: Methane from manure, ammonia from fertilizers.
• Dust Hazards: Grain dust, feed dust.
• Hybrid Mixtures: Likely in storage and processing facilities.
7. Woodworking Industry
• Gas Hazards: Not common.
• Dust Hazards: Sawdust, wood shavings.
• Hybrid Mixtures: Uncommon but possible in specific circumstances.
8. Textile Industry
• Gas Hazards: Solvent vapors.
• Dust Hazards: Fiber dust.
• Hybrid Mixtures: Possible in specific manufacturing processes.
9. Metalworking Industry
• Gas Hazards: Hydrogen, acetylene, welding gases.
• Dust Hazards: Metal dust, grinding dust.
• Hybrid Mixtures: Possible in certain operations like cutting and welding.
10. Paper and Pulp Industry
• Gas Hazards: Chlorine, chlorine dioxide.
• Dust Hazards: Paper dust, pulp dust.
• Hybrid Mixtures: Possible in processing areas.
11. Waste Treatment and Recycling Industry
• Gas Hazards: Methane, hydrogen sulfide.
• Dust Hazards: Various dust types depending on materials.
• Hybrid Mixtures: Possible in waste processing facilities.
12. Paint and Coatings Industry
• Gas Hazards: Solvent vapour.
• Dust Hazards: Powdered pigments.
• Hybrid Mixtures: Possible in manufacturing and application processes.
Each of these industries needs to manage their specific risks related to gas, dust, or hybrid mixtures to prevent explosive atmospheres and ensure safety.
