Class l Groups:
  • Group A: Acetylene
  • Group B: Hydrogen
  • Group C: Ethylene
  • Group D: Propane and Methane (mining)

Division 2: A location where a classified hazard does not normally exist but is possible to appear under abnormal conditions.

Temperature Classifications:
  • T3A: Max Surface Temperature – 180°C (356°F)
  • T3C: Max Surface Temperature – 160°C (320°F)

ETL Listed Mark: The ETL (Electrical Testing Laboratories) Listed Mark is a widely-recognized proof that products have been independently tested and meet the applicable published standards (per Intertek).
