1. LED explosion-proof lamps with appropriate explosion-proof levels should be selected in different environments, and different explosion-proof measures should be taken to ensure environmental safety. Firstly, distinguish the size and level of hazardous environments.

2. According to the degree and duration of the mixture in the hazardous gas, the ventilation conditions in the hazardous area, the characteristics of the release source, and the performance parameters of the hazardous materials.

The hazardous area is divided into three zones: Zone 0, Zone 1, Zone 2, Zone 10, and Zone 11.

1. Zone 0 refers to an area where explosive gases, vapors, or mist occur continuously or frequently for a long time or in a short period of time during normal operation. Except for enclosed spaces with hazardous substances, there is rarely a zero zone.

2. Zone 1 refers to the area where periodic or occasional occurrence of harmful gases, vapors, or mist is expected during normal operation.

3. Zone 2 refers to an area where harmful gases, vapors, or mist do not appear during normal operation, and even if they do, they only occasionally appear in a short period of time.

4. Zone 10 refers to the area where Baoza dust and fibers frequently appear continuously, for a long or short period of time during normal operation.

5. Zone 11 refers to an area where explosive dust and fibers do not occur during normal operation, but only occasionally occur during abnormal operation.
