Speaking of being only slightly killed, there was a post above about spraying near a space heater. If it has an open flame or even red-hot electric elements I reckon the outcome could be unhappy. Several years ago a house painter was spraying with lacquer inside a house under construction in my neighborhood. The fumes ignited, the entire house exploded in flames, the painter was killed, and the house burned to the ground. Apparently a gas heater element ignited the mix. This is one reason I paint outdoors, since the water heater and furnace in my garage are both natural gas powered and have open flames when they kick on. Better to have some bugs in the finish than be dead.
