What are the ATEX zones?
ATEX
| Zone Classification for Gases | |
|---|---|
| Zone 0 | That part of a hazardous area in which a flammable atmosphere is continually present or present for long periods. |
| Zone 2 | That part of a hazardous area in which a flammable atmosphere is not likely to occur in normal operation and, if it occurs, will exist for a short period |
Is iPhone 11 intrinsically safe?

Zone 1: An area in which an explosive gas atmosphere is likely to occur in normal operation; Zone 2: An area in which an explosive gas atmosphere is not likely to occur in normal operation and, if it occurs, will only exist for a short time.
What is gas group IIA IIB?
– Group IIA—Atmospheres containing propane, or gases and vapors of equivalent hazard. – Group IIB—Atmospheres containing ethylene, or gases and vapors of equivalent hazard. – Group IIC—Atmospheres containing acetylene or hydrogen, or gases and vapors of equivalent hazard.

Which temperature class is better T3 or T4?
It is understood that equipment should not be installed in an explosive atmosphere where the surface temperature is greater than 80% of the auto-ignition temperature of the gas….Temperature Classifications.
| CLASS | SURFACE TEMPERATURE °C |
|---|---|
| T3 | <200 |
| T4 | <135 |
| T5 | <100 |
| T6 | <85 |
Is IIB better than IIA?
Gases in Gas Group IIA require a higher ignition energy than Gas Group IIB. Gases in Gas Group IIC require the lowest ignition energy to ignite. As the table below shows, there are only 5 gases in Group IIC. Certifying your product for Gas Group IIA & IIB is usually sufficient to cover 98% of the market.
Is gas Group IIC better than IIA?
Group IIC is the most volatile group and the gasses in this group can be ignited quite easily. Any equipment which is marked as IIC can be used in atmospheres that contain Group IIB and Group IIA gasses. Conversely equipment marked IIA cannot be used in IIB or IIC explosive environments.
