Very open ended question.
Are you "producing paint", or are you "using paint to paint something else"?
What kind of paint? Combustible, flammable? Liquid? Powdercoat? Urethane? What's the MSDS say?
How are you applying it? Sprayed on with compressed air? Electrostatic spray gun, or conventional HVLP? By people, or by robots?
High production volume and usage (e.g. a car body every 60 seconds), or piddly nothing (e.g. someone squirting paint on a little piece in a spray booth every now and again)?
