Battery acid and lead compounds and the risk of explosion due to the build up of explosive gasses should be discussed. The hazards with nickel cadmium batteries, which contain highly corrosive potassium hydroxide and give off hydrogen, should be discussed. No persons should be allowed to enter a battery room without the correct clothing.
The employer must know, document and train the employee for the assigned task and exposed risks. It is a requirement to have all the documentation in place prior to authorized personnel entering a battery room to perform a specific work task on a battery system under normal operating conditions.
Fully detailed information can be found in International Standards such as BS EN 50272-2:2001. This article gives an overview only to the more important subjects. Battery rooms can be a hazardous place and all persons entering must be aware of the dangers. All too often, inexperienced people enter a room without receiving any safety information.
Common standards in the battery room include those from American Society of Testing Materials (ASTM) and Institute of Electrical and Electronic Engineers (IEEE). Model codes are standards developed by committees with the intent to be adopted by states and local jurisdictions.
Battery rooms should be designed with an adequate exhaust system, which provides for continuous ventilation of the battery room to prohibit the build up of potentially explosive hydrogen gas. During normal operations, off gassing of the batteries is relatively small.
Battery room layouts should be clean and designed to maximize space usage. Proper code clearances must be maintained in and around battery strings for required maintenance support and life safety systems. Egress aisles, exit ways, and maintenance aisles also must be maintained.

Get PriceBattery rooms must be equipped with exhaust means, which is usually a fan exhausting air to the outside of the building. Local and regional fire codes will set the requirements. Because air exchanges in most computer rooms far exceed the ventilation of a normal work environment, placement of battery cabinets in a computer room is rarely a problem.
