This recommended practice discusses factors relating to electrolyte spill containment and management for vented lead-acid (VLA)@ valve-regulated lead-acid (VRLA)@ vented nickel-cadmium (Ni-Cd)@ and partially recombinant Ni-Cd stationary batteries. Purpose This recommended practice is intended to educate those who are responsible for battery system design@ operation as it relates@to environmental and health practices. It seeks to develop a full understanding of and describe some electrolyte spill containment and management issues related to stationary battery systems@ and the ways in which battery chemistry and construction can influence requirements for spill containment and neutralization.
