Study Notes
Fire Precautions
- Electrical Staff Duties: Railway officers and supervisors are responsible for ensuring installations, offices, shops, and rolling stock are protected from fire, equipped with appropriate fire-fighting equipment, and staffed with well-trained personnel for fire response.
- Fire Prevention: Most fires are preventable through security-minded checks of installations and prevention of debris buildup.
- Periodical Checks: Inspections should confirm that fire-fighting appliances are in working order, staff are trained, and proper liaison with fire fighting organizations is maintained. Drill registers confirm last fire drill dates.
- Fire Classification: Fires are classified into A, B, C, and D types.
Fire Classification
- Class A: Organic materials (wood, paper, plastics) requiring water for extinction.
- Class B: Flammable liquids (petroleum products) needing blanketing agents for extinction.
- Class C: Flammable gases (liquefied gases) needing agents to inhibit burning.
- Class D: Reactive metals (magnesium, aluminum). Requires special media and techniques for extinction.
Fire Precautions in Electrical Equipment
- Water-based extinguishers ineffective: Water spray and foam extinguishers are unsuitable for electrical fires.
- Extinguishment methods: Employ insulating agents like sand, carbon tetrachloride, carbon dioxide, or halon for electrical fires.
- Preventing electrical fires: Ensure proper electrical equipment installation, maintenance, and operation to prevent arcing, sparks, or overheating.
- Handling electricity: Do not store combustible materials near electrical equipment and ensure electrical parts are properly earthed.
Fire Prevention and Extinguishment
- Prevent fires on vehicles: No smoking or open flames is permitted around fueled vehicles. Cleanliness is essential around areas where paints, varnishes are stored or used.
- Special Fire Considerations: Ensure safety measures in oil storage areas, battery rooms, and places harboring combustible materials. Maintain well-kept clearances of trees and rank vegetation from substations. Check for flammable materials in welding zones.
- Electrical Equipment Maintenance :Inspect electrical equipment for faults, check insulation strength, and document temperature and loading conditions. Ensure electrical lamps, cables, and battery rooms are free from flammable materials.
- Fire Safety Organization: Railway organizations have specific fire fighting organizations for major incidents, with responsibilities given to the Chief Security Commissioner.
- Fire Investigations: Investigate every fire, major or minor, and analyze causes for improvement.
- Training: Drivers, motormen, and other staff involved in operations must be trained on locating, operating, and using fire suppression equipment, according to the necessary regulations.
Staff Training and Responsibilities
- Fire fighting staff training: Supervisors, staff, and skilled artisans of various sections must be trained in fire fighting equipment operation, location, and safety procedures.
- Maintenance Personnel Training: Specific staff for inspection, testing, and maintenance of fire extinguishers must be trained. Maintaining and inspecting fire equipment is mandatory, with specific intervals.
- Annual Inspections: Fire extinguishers are to be inspected and maintained annually.
Fire Extinguishers
- Suitability of extinguishers: Table 1 provides suitability ratings for various extinguisher types on the different classes of fires. Certain extinguishers, based on the type of fire, are more effective.
- Safety in Electrical Equipment Fires: It is important to recognize that electrical fires require particular attention to the use of water or other non-conductive extinguishing media.
- Prevention strategies: Maintenance and inspection of the extinguishers are important. Procedures for maintenance are provided.
