Battery room hazards include; electrical, chemical, fire, respiratory, ergonomic, and sheer weight of the battery jars.  Addressing each of these concerns is critical to battery room safety.  In-house maintenance personnel, AC electricians and fly-by-night battery installers often do not have the training, experience, and correct tools to work with these systems according to published battery room safety standards.  It is for this reason that using a professional company that specializes in industrial battery installation, removal, and maintenance is the safest choice for this specialized work.

Battery safety standards that cover working safe in battery rooms include;

This standard covers basic OSHA safety requirements for employees who work on or near electrical systems.  It addresses training, live work, lockout, approach distances, equipment requirements, grounding, protective insulation, signage, barricades, etc…  It is however not battery specific.

This standard for general industry addresses battery ventilation to prevent explosion.

This standard for construction addresses battery ventilation, racking, battery room floors, PPE, safety eye wash location distances, safety shower location distances, and battery charging safety requirements.
