A potentially explosive atmosphere exists when a mixture of air, flammable gas/vapor/mist or dust is present in such a way that it may ignite under certain operating conditions. In such flammable atmospheres, special attention should be paid to equipment and protective systems used for operational purposes, as they may cause explosions through friction, hot surfaces and many other methods. While they are everywhere, we can identify them and apply appropriate controls.

Zhunyun consultants can carry out ignition source assessment in accordance with EN13463, NFPA77 and other standards.

Ignition source categories include:

1. Hot surface

2. Open flames and hot gases (hot particles)

3. Mechanical spark

4. Electrical equipment

5. Stray Currents and Cathodic Protection

6. Electrostatics

7. Lightning

8. Low-frequency electromagnetic waves

9. Medium-Frequency Electromagnetic Wave

10. ionizing radiation

11. Ultrasound

12. Adiabatic compression and shock waves

13. Exothermic reactions including spontaneous combustion of dust
