Reversing Blind Spot — India में Power Plants की सबसे Common Fatal Accident है। Problem: Large Dump Truck में Rear Visibility Almost Zero। Mirrors Insufficient। Solutions — Multiple Layers: (1) Spotsman System — Trained Ground Person रहे पीछे। Red Flag Signal = Stop Immediately। Radio Contact। (2) Reverse Camera — CCTV Display in Cab। (3) Reversing Alarm — 85 dB+ Audible। (4) Radar/Sonar — Proximity Detection Device। (5) Exclusion Zone — Reversing Area में No Personnel। (6) Reversing Route — Pre-planned। Fixed Reversing Lanes। (7) Spotsman PPE — Hi-Vis Class 3 + Helmet + Safety Shoes। Emergency Action: यदि Worker हो — STOP, Sound Horn, Spotter Call। Never assume "nobody behind।" CEA Best Practice: Dumping Zone के लिए Dedicated Spotsman + Camera System = Mandatory।

HV Line Contact — Life-threatening Emergency। Operator for Survival: (1) DON'T JUMP OUT — जब तक Line Attached हो — मशीन Energized है। (2) Stay in Cab — Rubber Tyres/Tracks = Insulation। (3) Horn Press करें — Others को Alert करें। (4) Slowly move Excavator Away from Line — यदि Possible। (5) यदि Machine cannot move और Fire Risk हो — Jump with Both Feet Together — No Ground Touch — होप करते हुए बाहर जाएँ। Ground Action: (1) Others को 15 मीटर दूर रखें। (2) Power Company को Call — Emergency। (3) Power OFF होने तक Machine को Touch नहीं। (4) Ambulance Call। Prevention: (1) Site Entry — HV Line Map Provided। (2) Proximity Warning Device on Crane/Excavator। (3) Permit — HV Near Work। (4) Morning TBT — HV Lines Briefing।

Ash Dyke — Unique और Extremely High-Risk Environment। Special Hazards: (1) Soft Ash Ground — Truck Sink। Unexpected Settlement। (2) Dyke Edge — No Barrier। Rollover = Ash में डूबना। (3) Dust — Zero Visibility। (4) Pipe and Cable — Ash Area में। (5) Access Road — Narrow, Wet, Unstable। Safety Requirements: (1) Berm / Edge Protection — Minimum Half Wheel Height Earthen Berm। (2) Ground Bearing Check — Soft Areas में Plate Test। (3) One-way Traffic — Ash Dyke पर।(4) Dust Suppression — Water Tanker Spraying। (5) Dumping Protocol — Operator gets out, walks to Edge, checks, then moves Truck। (6) Wheel Chocks — यदि slope। (7) Emergency Rescue — Ash में Sunken Vehicle। (8) DGMS Ash Dyke Safety Guidelines Follow करें।

Lift Plan — Crane Accident Prevention का Core। CEA और IS 3938 — Written Lift Plan Mandatory। Types of Lifts: Simple Lift — Standard Lifts, Well within SWL। Critical Lift — SWL का 75%+, Near HV Lines, Personnel Overhead, Multiple Cranes। Lift Plan Content: (1) Load Weight — Exact (Not Approximate)। (2) Crane Capacity at Required Radius — Load Chart। (3) Ground Conditions — Bearing Capacity, Outrigger Pads। (4) Rigging — Sling Type, Size, Angle, SWL। (5) HV Lines Distance — Clearance Calculation। (6) Personnel — Signal Person, Rigger, Banksman। (7) Emergency Plan — What if Sling Breaks? When Plan needed: Every Non-routine Lift। Critical Lifts = Engineer Signed Lift Plan। Routine Repetitive Lifts = Generic Procedure + Daily Review। Risk: Crane Accidents = 10-50 m Fall। Lift Plan = Life-saving Document।

Traffic Management Plan (TMP) — Power Plant Safety का Core Document। DGMS और CEA Requirements: Document Contents: (1) Site Map — All Roads, Vehicle Routes, Pedestrian Paths। (2) Traffic Flow Diagram — One-way Routes, Roundabouts। (3) Speed Limits — Zone-wise। (4) HV Crossing Points। (5) Pedestrian Crossing Locations। (6) Vehicle Operating Hours — Different Zones। (7) Hazardous Goods Routes। Implementation: (1) Road Signs — DGMS/IS Standard। (2) Road Markings — Yellow Lines, Stop Lines, Crossings। (3) Barriers — Jersey Barriers, Traffic Cones। (4) Traffic Marshals — Intersections, Reversing Areas। (5) Speed Bumps — Near Buildings, Crossings। Review: Monthly Review — Incidents, Near Misses। Annual Audit — Compliance Check। New Work = TMP Update। Note: Coal Handling, Ash Handling Area = Separate TMP। Monsoon = Additional Measures।

Forklift-Pedestrian Collision — Warehouse और Store में सबसे Common Fatal Accident। Engineering Solutions: Physical Separation: (1) Yellow Physical Barriers — Racks, Walls के सहारे। (2) Pedestrian Gates — एक ही Entry Point। (3) Floor Markings — Yellow Lines, Hatched Areas। (4) One-way Aisles — Minimum Width 3.6 मीटर। Technology Solutions: (1) Forklift Blue Safety Light — Floor पर Projection = Warning। (2) Proximity Sensors — Personnel Detection — Forklift Slow। (3) CCTV + AI — Worker Detection। (4) Speed Governors — Zone-wise। (5) Pedestrian Tag + Forklift Alarm — RFID System। Administrative: (1) Forklift Hours — Specific Time Windows। (2) Personnel Hours — Different। (3) Permit to Enter — Active Forklift Zone। (4) Buddy System — Warehouse में। Speed Limits: Indoor = 8 km/h। Near Pedestrians = 4 km/h (Walking Speed)।

Pre-shift Inspection — Equipment Safety का First Line। OSHA और IS Standards: Walk-around Inspection (Before Start): (1) Tyre — Pressure, Cuts, Wear, Flat Tyre। (2) Engine — Leaks, Hoses, Belts, Fluid Levels। (3) Safety Devices — ROPS Condition, Mirrors, Horn। (4) Lights — Headlights, Reverse Light, Warning Flasher। (5) Hydraulics — Cylinder Rods, Hose Condition, Leaks। (6) Undercarriage — Tracks/Tyres, Sprockets (Excavator)। (7) Cab — Seatbelt, Windows Clear, Fire Extinguisher। Start-up Check: (1) Warning Lights — Check all Clear। (2) Brake Test — Parking + Service। (3) Steering — Full Lock। (4) Hydraulics — Raise/Lower Cycle। (5) Horn, Lights — Function Test। Record: Pre-shift Checklist Sign। Defect = Write और Report = Equipment parked। Benefits: 80% Mechanical Failures are Detectable During Pre-shift। Prevents In-service Failure।
