I thought a little more about what you said about gas fumes, I assume you mean gasoline fumes. You are very correct. If you store gas, or are working with gas, fuel system, where fumes may be present, thinners, or cleaning solvents that are flammable. The best policy (safety wise) is to turn off all heat sources. Now commercial shops where they have high ceilings, normally use hanging heaters, well above floor level and fumes. My advice where alot of us are working in small garages, with low ceilings is to be extremely careful with any type of heaters when working with anything that may produce combustible fumes. When I paint inside and it's cold I heat up garage and turn off all heat, even water heater, which has a closed combustion chamber. Electric heaters, (radiant type) are just as dangerous as gas or oil fired heat. In a small garage probably the safest heater is a sealed oil filled electric heater. But in the presence of fumes even a light switch can be dangerous. That is the main reason I keep gas cans, and most thinners out of the garage. Period............
