What is the difference between Division 1 and Division 2 hazardous locations?

What will be an ideal response?


Hazardous locations are divided into two divisions that depend on the likelihood of the hazard being present. Division 1 locations are areas considered to be hazardous at any or all times during normal operations. Division 2 locations are areas that could become hazardous through a foreseeable accident. For example, an area in which gasoline is manufactured would be considered Class I, Division 1. An area in which maintenance is done on trucks that transport the gasoline would be Class I, Division 2.
