Batteries of the unsealed type are to be stored in well-ventilated rooms or in enclosures with outside vents.
Batteries being charged must be in a well-ventilated open or outside area. Vent caps must be functioning properly and in place. Fumes must not be allowed to migrate into confined rooms or spaces.
There must always be a means in the immediate vicinity of charging operations to adequately wash out eyes and flush skin with water. An appropriate fire extinguisher must also be located in the vicinity of all battery charging operations.
