Three basic data are required to define the necessary protection.
In which there are potentially explosive atmospheres.
Based on the gases or dust potentially present, the vehicle should be protected to ensure it does not reach detonation temperature.
This maximum surface temperature does not depend on the classified Zone, but rather, on the gases or dust present.
GROUP OF GASES
The gases that can be found in the industry today are divided into three groups, based on their physical properties; for example: minimum ignition energy, etc.
