I don't no the use besides storage. The hangers are 20 feet high by 45. Are lights, Receptacles and switches fall under the Art 513. Also their is a Motor controller setup for bi-fold doors.

513.3 tells you what you are looking for.

513.3(A) and (B) tell you everything on/below floor level is classified up to 18 inches above the floor.

513.3(C) gives you additional classified areas within the aircraft vicinity, main emphasis is on the location of power plants and fuel tanks. second part is for a hanger where painting activity will occur.

Ventilation and methods of cutting off the area to effectively make a different space can come into play in defining classified areas.

Lights, switches, receptacles in a common storage hanger only present problems if below 18" above the floor or if they are too close to power plants/fuel tanks, I would think they mean where the usual storage location of the plane is when determining the location. If you have a plane that barely fits into the hanger (not uncommon at small rural airports) - you need to watch more closely where the hazardous location is, if they are not trying to stuff the plane into a tight box - your overhead dimensions are the main ones that can get you.

Why Would You Need an Explosion Proof Package?

Knowing whether your project falls under division 1 or 2 can save you time and money in the long run. It ensures that you will receive the correct electrical package for your shelter.  If you try to use one switch, fixture or receptacle that does not have the appropriate hazardous location rating, it negates the hazardous location rating of all the other components in the system and compromises the safety of your project.

At Shelter Works, it’s our job to ensure something like that never happens, so we want to hear all about the applications, environment and/or special circumstances for your next project.  Let one of our sales engineers help you ensure the safety and compliance of your most critical field equipment sales.
