Does Class 1 Div 2 require explosion proof?
While Division 1 motors in Class I locations must be explosion-proof, Class II, Division 1 motors must be dust- ignition-proof. One important distinction is that the enclosure of a dust-ignition- proof motor is designed to exclude hazardous materials.
What is class1 luminaire?

What is a Class 2 hazardous location?
Class II Locations The second type of hazardous location is called a “Class II Location”. This classification is created by the presence of combustible dust in the air in sufficient quantities to be explosive or ignitable.
What makes a light explosion proof?
To be certified, explosion-proof lights typically will be made of durable, non-sparking material, a very thick glass globe over the bulb, and other features to ensure that the worker and the surrounding environment remains safe should an ignition occur inside the light.
