There are some serious things to consider when setting up an area that is “explosion proof”. Is the fan motor going to be exposed to the fumes/vapors? If yes then it must be explosion proof. How are you lighting the area? This must also be explosion proof along with the switches. You need to look at how the chemicals/paints are moving in the spray lines and how you transfer the chemicals.. This will create a static charge and can ignite in an explosive area. This is a very serious issue and needs to be taken seriously. I work in Industrial Safety and have read many fatal reports of people burning up when the atmosphere that they are working in explodes. All of the safety rules and laws out there are written in the blood of others. Don’t end up a statistic.
