  • 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...
