Safety Manual for Coal Handling Plant
The coal handling plant (CHP) is a critical facility in thermal power stations, responsible for receiving, processing, storing, and feeding coal to boilers. Due to the inherent hazards associated with coal handling, strict safety protocols must be followed to ensure the well-being of personnel and the integrity of equipment. This manual outlines essential safety measures to mitigate risks such as fires, explosions, dust inhalation, and mechanical accidents.
General Safety Guidelines
1. Personal Protective Equipment (PPE): All personnel must wear appropriate PPE, including hard hats, safety goggles, gloves, dust masks, and steel-toe boots. High-visibility vests are mandatory in operational areas.
2. Training: Workers must undergo regular safety training covering emergency procedures, equipment operation, and hazard recognition. Only trained and authorized personnel should operate machinery.
3. Housekeeping: Maintain cleanliness to prevent coal dust accumulation, which poses fire and explosion risks. Spills should be cleaned promptly, and walkways kept free of obstructions.
4. Signage: Clearly mark hazardous zones with warning signs indicating risks such as moving machinery, high voltage areas, or confined spaces.
Fire and Explosion Prevention
Coal dust is highly combustible; even small sparks can trigger explosions. Implement the following measures:
- Regularly inspect and clean dust extraction systems to minimize airborne particles.
- Prohibit smoking or open flames in CHP areas. Use intrinsically safe tools where necessary.
- Install fire detection and suppression systems, including sprinklers and extinguishers rated for Class A (solid combustibles) and Class B (flammable liquids) fires.
- Conduct routine checks on electrical equipment to prevent short circuits or overheating.
Mechanical Safety
Moving machinery like conveyors, crushers, and stacker-reclaimers pose entanglement or crushing hazards:
- Ensure all guards and interlocks are in place before operating equipment. Never bypass safety devices.
- Follow lockout/tagout (LOTO) procedures during maintenance to isolate energy sources completely.
- Use designated walkways and avoid crossing conveyor belts unless absolutely necessary via approved crossover points.
Emergency Preparedness
1.Establish clear evacuation routes with illuminated exit signs.Conduct regular drills simulating scenarios like fires,dust explosions,and equipment failures.Maintain first aid kits stocked with burn dressings,dust flush solutions,and other essentials.Train staff in basic first aid CPR,and rescue techniques.For major incidents activate onsite emergency response teams
