FIRE PREVENTION

Electrical Fire Power Plants में सर्वाधिक Common (40-50% Cases) है। कारण: (1) Heavy Electrical Load — Cables Overheat, (2) Aging Infrastructure — Old Insulation, (3) Transformer Oil — Highly Flammable, (4) High Fault Currents — Arc Flash, (5) Harmonic Distortion — Cable Heating। Prevention: (1) Thermographic Survey — Annual IR Scanning — Hot Spots की Early Detection, (2) Cable Loading — Derating Factor Apply करें, (3) Transformer Oil Testing — Dielectric Strength, Dissolved Gas Analysis (DGA), (4) Overload Relays — All Motors पर Set, (5) Fire Resistant Cables (FRLS/LSZH) — New Installations में, (6) Cable Tray Sealing — Zone-to-Zone Fire Barrier, (7) Fixed CO₂/Clean Agent System — Control Room और Data Centre। CEA और IE Rules की Annual Electrical Inspection। IR Thermography Report 3 साल रखें।

Coal Spontaneous Combustion (Self-heating) Coal की Chemical Property है। Process: Coal में Carbon Oxidation — Heat Release — Temperature बढ़ती है — Ignition। Conditions: Large Coal Piles, Poor Ventilation, Moisture, Fine Coal Particles। Warning Signs: (1) Unusual Smell (Sulfur), (2) Bluish Smoke, (3) Temperature Probes 55°C+ Show। Prevention: (1) FIFO Principle — 3 महीने से पुराना Coal पहले Use, (2) Coal Stack Height — Maximum 6-8 मीटर, (3) Temperature Probes — Regular Monitoring, (4) Water Spraying — Stack Temperature 55°C+ पर, (5) Compaction — Air Pockets कम करें, (6) Coal Segregation — Fine Coal अलग रखें। CEA Coal Handling Standards और NFPA 850 Reference। Once Ignited: Water से Control — Carbon Dioxide नहीं।

Practical Fire Extinguisher Training Essential है। Training Methods: (1) Propane Fire Training Pits — Controlled Fire पर Actual Practice, (2) Laser-based Training Extinguishers — No mess, Realistic Simulation, (3) Water Mist Extinguishers — Regular Water, Reusable, (4) PASS Technique Walk-through — Dummies के साथ Demonstration। Training Elements: (1) Extinguisher Type Identification, (2) PASS: Pull → Aim → Squeeze → Sweep, (3) Wind Direction — Always Attack from Upwind, (4) Exit Route Maintenance — Never Turn Back to Fire, (5) "When NOT to Fight" — Large Fire, No Exit, Unknown Material। Frequency: Annual Practical Training — NFPA 10 और CEA Reg. 55। Record: Training Attendance + Type of Extinguisher Practiced। Mock Fire Drill में Real Extinguishers Discharge कराएँ — Empty Cylinders Refill करें।

30-Minute Post-Hot-Work Fire Watch NFPA 51B का Minimum Standard है। Many jurisdictions और Plants इसे 60 मिनट तक extend करते हैं। Why 30 minutes? Smouldering Fire — Welding Spatter Wood/Insulation में Embed हो जाती है और धीरे-धीरे सुलगती है। Visible Flame तुरंत नहीं आती। Historical Incidents: (1) USS Forrester Fire 1967 — Hot Work Sparks + Fuel, (2) Multiple Industrial Fires globally, Post-Work। Best Practice: (1) Fire Watch 30 मिनट Minimum, Ideally 60 मिनट, (2) यदि Combustibles हटाए नहीं जा सके — 4 घंटे Watch, (3) यदि Material पर Water लगाया — 30 मिनट और, (4) Fire Watch Person का Name, Time PTW पर Record। CEA OSEP में Hot Work Incidents का Case Study Include करें।

Inspection Tag Fire Extinguisher की Maintenance History का Official Record है। Monthly Inspection Checklist: (1) Safety Pin/Tamper Seal — Intact है?, (2) Pressure Gauge — Green Zone (Operating Pressure), (3) Hose/Nozzle — Block नहीं, Cracks नहीं, (4) Label — Readable, Type Correct for Location, (5) Physical Damage — Dents, Corrosion, (6) Mounting — Secure Bracket, Eye Level 1-1.5 मीटर। Annual Inspection (Service): Internal Inspection, Refill/Recharge, Hydrostatic Test (5 वर्षों में)। Inspection Tag पर: Date, Inspector Name, Result, Next Due Date। CEA Audit में 3 साल का Inspection Record दिखाना होता है। IS 2190 — Fire Extinguisher के पास Red Arrow Sign और Location Marker।

Large Fire में RACE Protocol Follow करें: R — Rescue (लोगों को हटाएँ), A — Alert (Alarm Activate करें), C — Contain (Fire को Spread होने से रोकें), E — Extinguish (Small Fire) या Evacuate (Large Fire)। "When NOT to Fight" Rules: (1) Fire आपके आकार से बड़ी है, (2) Toxic Smoke है, (3) आपके पास Exit नहीं है, (4) आपको Training नहीं है। Large Fire में: (1) Evacuation Alarm Activate, (2) Plant Head और Fire Brigade (101) Call, (3) Power Isolate यदि Safe हो, (4) Gas Supply Isolate, (5) Evacuation Route से बाहर — Assembly Point, (6) Fire Team को Access दें — Route Clear, (7) Re-entry नहीं जब तक Fire Officer All Clear न दे। CEA Emergency Plan में Large Fire Protocol Documented होना चाहिए।

Transformer Oil Fire = Class B Fire — Flammable Liquid। Water क्यों नहीं: (1) Steam Explosion — Oil बहुत गर्म होता है, Water Steam बनती है और Explosion, (2) Electrical Conductivity — Live Transformer पर Water = Electrocution, (3) Oil Scatter — Burning Oil पानी से Spread होती है। Correct Options: (1) AFFF Foam — Foam Blanket O₂ Cut करती है — Transformer Oil के लिए Best, (2) DCP — Effective है लेकिन Equipment Damage होता है, (3) CO₂ — Small Electrical Fire के लिए, Large Oil Fire के लिए Insufficient। Best Practice (CBIP Manual): (1) Fixed AFFF Deluge System — Transformer Bay में Automatic Activation, (2) Oil Bund Wall — Burning Oil को Contain करे, (3) Oil Drain System — Remote Drain Valve — Cooling, (4) Mobile Foam Tender — Backup। Never use Water on Transformer Fire।

हाँ, Plant में Smoking को Strict Zones तक Restrict करना Legally Supported है। Legal Basis: (1) Factories Act Section 36B — Intoxicants on Duty — Management का अधिकार है Restrictions लगाने का, (2) COTPA (Cigarettes and Other Tobacco Products Act 2003) — Designated Smoking Areas Only, (3) CEA और NFPA — Fire Hazard Zones में Absolute No-Smoking, (4) Companies Act और Contract Terms — Safety Rules में Smoking Ban Include करें। Hazardous Area में Absolute Ban: Coal Handling, H₂ Storage, Fuel Oil Area, Chemical Store — यहाँ Smoking Fire का Direct Cause बन सकता है। Best Practice: (1) Designated Smoking Zones — Plant Boundary के पास, Fire-safe Location, (2) No-Smoking Signs — IS 9457 के अनुसार, (3) Lighter/Match Confiscation — Gate Check, (4) Violation = Disciplinary Action, Repeat = Termination। Legal Tip: Plant Safety Policy में Smoking Ban documented करें — Workers को Acknowledge कराएँ।
