This guide has been developed to address electric substation fire risk. The substation fire risk strategies in this document are based on industry standards and good practices. Lessons learned are incorporated from substation fires, research and testing, advancements in fire protection and environmental concerns.

This guide provides fire protection design guidance for substation engineers and others involved in substation fire safety and protection to reduce the risk of fire. Careful consideration of the consequences of a substation fire and alleviating those consequences throughout the planning and design process will help to mitigate the consequences of a fire in a substation. Properly designed substation fire protection can minimize the effect of component failure during a fire on overall reliability of the system supply. Having fire protection systems and processes will help minimize the asset and revenue losses from any fire.
