The objective of this Standard is to specify minimum requirements for the installation of vented leadacidbatteries and vented alkaline batteries to ensure safety from fire and electric shock.
Both the ampere-hour capacity and voltage of battery installations have increased to the point where some voltages now border on the medium and high voltage range. Even in extra-low voltage installations, the low internal resistances of batteries under short-circuit conditions can cause severe injuries to staff working on a battery or cell, or cause fire and explosion.
Tests have shown that batteries of 24 V d.c. and above may present problems in breaking fault currents and that additional precautions need to be taken to reduce the possibility of accidental short-circuits.
In preparing this Standard, the Committee considered the requirements of both vented lead-acid cells and vented alkaline cells.
