Vented batteries emit explosive gases when being charged. Ventilate the charging area. Never smoke or have open flames in a non-ventilated battery area. Explosive gases can be set off by a match, incorrect connection of battery cables, and careless use of tools around the battery. Use proper lifting techniques when moving batteries.
Batteries are small, but heavy and awkward to lift.
Back, shoulder and arm injuries are avoidable by using a battery carrying strap. When removing the battery from the buggy, slide it to a convenient spot, grasp firmly and lift with the legs. Lifting, while reaching over the side of the buggy can cause injury. When picking up a battery from the floor or low shelf, keep the back straight and lift with the legs.
