[quote=benedict]One word on respirators: Be sure to match the respirator to the job. I know this is common sense, but I've seen people painting with a dust mask on, assuming it'll cut the fumes. I've also seen people using an acid gas / organic vapor cartridge in a respirator when they're sanding, assuming it'll cut the dust. If you're generating dust, use a dust mask or have a dust filter in your cartridge. If you're using volatiles, an organic vapor or acid gas / organic vapor cartridge is called for.
In ALL cases, your best bet is to ventilate very very thoroughly. Respirators can only work up to a given concentration level in the air. Past that they're not doing much for you. So if you lower the concentration through ventilation, your respirator won't have to work as hard and will be more effective overall.
