Definition(s)
Hazardous Area
Three-dimensional space in which a combustible or explolsive atmosphere can be expected to be present frequently enough to require special precautions for the control of potential ignition sources
- Note: 1 to entry: Hazardous areas are typically defined by local, national or international standards (e.g. the National Electric Code (NEC) in the United States).
