What is the primary fire concern for blast furnaces?

Explosion hazards from water contact with molten metal and fire hazards from hot surfaces and hydraulic oils. (Refer to clauses on specific plant areas).

What type of extinguisher is used for metal fires?

Class D fire extinguishers using specialized dry powders are required for combustible metal fires. (Refer to clause on fire extinguishing appliances).

Are sprinklers required everywhere in a steel plant?

No, they are recommended for specific high-risk areas like cable galleries and conveyor belts, but are unsuitable where water can cause a dangerous reaction, e.g., near molten metal. (Refer to clause on fire protection systems).

What is the recommended spacing for external hydrants?

45 meters, positioned so that all sides of a major building are accessible. (Refer to Clause 6).

Practical Notes

Focuses heavily on plant-specific hazards like coke ovens, blast furnaces, and rolling mills which are not covered in general fire safety codes.

Emphasizes the importance of a dedicated, well-trained plant fire brigade due to the specialized nature of fires (e.g., metal fires).

Special attention should be paid to the recommendations for managing coal dust and flammable gases, which are primary fire and explosion risks.
