Battery cabinet safety distance requirements

According to NFPA 855, individual energy storage system units should generally be separated by at least three feet, unless the manufacturer has conducted large-scale fire testing (part of UL 9540A) to prove a smaller distance is safe. This prevents a fault in one unit from spreading. . Batteries of the unsealed type shall be located in enclosures with outside vents or in well ventilated rooms and shall be arranged so as to prevent the escape of fumes, gases, or electrolyte spray into other areas. According to UL 9540 the separation between batteries should e 3ft (91. UL 9540 also provides that equipment evaluated to UL 9540A with a written report from a nationally recognized testing laboratory (NRTL), such as ETL, can be permitted to be installed with less than 3ft. . That is where Article 320, Safety Requirements Related to Batteries and Battery Rooms comes in. Its electrical safety requirements, in addition to the rest of NFPA 70E, are for the practical safeguarding of employees while working with exposed stationary storage batteries that exceed 50 volts. However, the concern is elevated during times of heavy recharge or the batteries, which occur immediately following a rapid and deep. .
