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 valve regulated nickel-cadmium stationary batteries. Suggestions are made for drafting model codes. This recommended practice is intended to assist code-writing organizations. 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. New IEEE Standard - Superseded. Descriptions of products, methods, and procedures relating to stationary batteries, battery electrolyte spill mechanisms, electrolyte containment and control methodologies, and fire fighting considerations are provided.
