Fire-Fighting Precautions in Power Substation

Introduction to Fire ProtectionFire Safety Considerations in SubstationsDesign For Effective Fire ProtectionThe layout of the plant and the design of the building play a major part in reducing the spread of fireand the effect of explosions. For example, equipment and buildings should be arranged to have vents which rupture rather than allowing an explosion to damage the main fabric.Site supervisors should ensure that these vents are never obstructed. In the prevention of fire, cleanliness and tidiness are very important, as is the careful maintenance of tools. The choice of fire-fighting equipment is dependent on its suitability for electrical fires but also on cost and the importance of the electrical supplies at the point in question. Portable manual types are as follows: halon gas of various kinds, carbon dioxide chemical foam and powder. Fixed systems use water sprinklers, carbon dioxide and halon gas. Both halon gas and carbon dioxide can suffocate personnel trapped in the discharge area. Strict precautions must therefore be taken to lock-off the equipment when staff are present. The...Get price

Types and Origins of Substation Fires

Fires in SubstationsSubstation HazardsSwitchyard HazardsControl and Relay-Building HazardsIndoor Station HazardsThe risk of fire in substations has been historically low, but the possible impacts of a fire can be catastrophic. Fires in substations can severely impact the supply of power to customers and the utility company’s revenue and assets. These fires can also create a fire hazard to utility personnel, emergency personnel, and the general public. The recognition of the fire hazards, the risks involved, and the appropriate fire-protection mitigation measures are some of the key considerations for the design and operation of new or existing substations. This article provides an overview to help substation designers identify fire hazards within a substation, identify appropriate fire protection measures, and evaluate the benefit of incorporating these measures. It is only an overview and is not intended to be all-inclusive or to provide all the necessary details to carry out a project.Get price
