"IEEE 980 replaces IEEE 80." Fact: No. IEEE 80 is for high-voltage substations (above 69 kV). IEEE 980 is for industrial and commercial power systems (typically below 69 kV).
The standard was revised in 1996 (IEEE Std 980-1996) to address the growing popularity of VRLA (sealed) batteries. While VRLA batteries promised "maintenance-free" operation, they introduced new risks, such as thermal runaway and the potential for case rupture under pressure. The 1996 revision was a significant update, acknowledging that "sealed" did not mean "safe." ieee 980 pdf

standard, officially titled the IEEE Guide for Containment and Control of Oil Spills in Substations
If you design, inspect, or operate substations with oil-filled equipment, IEEE 980 is not optional background reading—it is a practical, prescriptive guide to preventing your next project from becoming an environmental disaster. It bridges the gap between civil engineering (containment), electrical engineering (equipment layout), and environmental science (spill control).
