Fire Safety Solutions- Scope of Discussion
Fire Safety Solutions
• Fire is an accident
• Accidents can be prevented
• Accidents can be prevented by following rules of System
• By following rules of Process or Operation without deviation
FIGHT FIRE WITH KNOWLEDGE
• Fire as an accident can be controlled by FAULT TREE ANALYSIS
• By eliminating
system faults
• By reducing system faults and failures
FIGHT FIRE WITH KNOWLEDGE
Fire Safety Solutions
• Fire causes Losses – large and small
• It is possible to eliminate Losses from Fire
• Losses in Plant & Machinery
• Loss of Life
• Detect the Fire early and protect from it

Fire Detection System-
• Why Automatic Systems ?
• Automatic systems work without human intervention
• Precious time is lost when we wait for Fire Fighters to come Fight
FIGHT FIRE WITH KNOWLEDGE
Fire Safety Solutions
• Automatic Fire Detection & Alarm System gives out audible & visible Alarm in the area protected
• It displays place of
occurrence of Alarm
• Automatic Fire Detection & Alarm System sends out pre-recorded Alarm messages over phone, mobile mail to Fire Brigade
• It repeats Alarm to security
• Fire Detectors• Flame Detectors• Gas Detectors• All connected with
Transmitters & Controllers
• Controlled by PLC or without PLC
• Connected to Plant DCS & Shutdown System

Fire Detection System-Scope of Improvements
Conventional System
Addressable System
Automated System Integrated
Automated System• Case Study –
Augmentation project
Implemented at IOCL – Haldia Refinery
• Result –A) Display of fire incident location in large format makes it
easy for fire brigade operators to respond & report to the location quickly.
B) Total quantity of cables have been reduced to very minimum. As a result the nightmare for the electrical maintenance department is over. C) All incident records are transmitted by E-mail to the concern departments. They are all available in server for future reference .
Integration =Gas + Fire Detectors

Fire Protection System-Scope of Improvements
• Case StudyIOCL Paradweep Refinery
• Result – Low Maintenance Cost Effective Time Saving – as no Welding
required
Ordinary Coupling Grooved Coupling
Selection of Total Fire Protection System
• Fire Hydrant System must be automatic
• It is simple• When the Fire Fighter
opens the Fire Hydrant valve, water must come out at full force
• All it needs a good pressure switch and reliable panel to start Pump set at fall of line pressure
FIGHT FIRE WITH KNOWLEDGE
Fire Hydrant System for General IndustriesDifferent Components
Pump auto operation switches
FIGHT FIRE WITH KNOWLEDGE
• New Improvements• More efficient & reliable pumps• PLC based MCC & Cabinets• Piping material & coatings• Pipe fittings – grooved couplings• Clevis hangers
FIGHT FIRE WITH KNOWLEDGE
Fire Hydrant Systems
• Automatic Sprinkler System
• Best possible for Indoor Protection
• Water will come out and fight fire in the room where Fire has occurred and limit it to that room
FIGHT FIRE WITH KNOWLEDGE
Fire Sprinkler Systems
Grooved couplings connected piping
FIGHT FIRE WITH KNOWLEDGE
• Sprinkler System design• Fast Response Sprinklers• Large orifice sprinklers• Sprinkler drop lines• Grooved Couplings
Fire Sprinkler Systems- Scope of Improvements
FIGHT FIRE WITH KNOWLEDGE
• Automatic Water Spray System
• For High Hazard Risks of Refinery , petrochemical risks, Oil Terminals – MVWS
• For Power Industry, Large Power Transformers – HVWS
FIGHT FIRE WITH KNOWLEDGE
Water Spray Systems
• Water Spray system design• Improved nozzles• Improved Deluge Valves – skid mounted• Piping material with grooved ends• Stainless Steel / CPVC pipes
FIGHT FIRE WITH KNOWLEDGE
Water Spray Systems- Scope of Improvements
• Fixed Automatic Systems
• For very large Oil Storage Tanks with Foam Proportioning & Pumping System
• Supported by Rim seal System
• Semi-fixed Systems for most of the Storage Tanks - Fire Brigade vehicle comes and pumps foam – lot of expertise & skill needed for success
FIGHT FIRE WITH KNOWLEDGE
Foam Systems
• For very large generators
• For cable trenches
• Actuated by a very reliable Detection system with Cross-Zoning
FIGHT FIRE WITH KNOWLEDGE
