I am heating up my pressurized storage tank for the first time. As the tank heats up I am noticing some new aromas. Some of the smells are to be expected as the tank heats up for the first time. I have not insulated yet because I am waiting to make sure all the connections hold as the pressure increases with temps. I temporarily have some fiberglass bat's laid on top of the tank to help retain some heat (this may be contributing to some of the problem). Anyway, the new smells have me wondering if the paint can be toxic as it heats up? The tank was hand painted and I have no way of knowing how old the paint is or if it has lead in it. I have the basement open and ventilating. I am hoping if anything toxic does come off the tank it will vent outside on the initial heating of the tank. Should I be concerned long term?
