FIGHT FIRE WITH KNOWLEDGE

• Fire Safety Solution with emphasis on Technology & how it benefits CUSTOMER

• Major advances in Fire & Gas Detection• Integration of Safety & Security Systems• Integration of Fire & Gas & Security

systems• Large Scale Networking with Fibre Optics• Alarm System Management – monitoring

of large no. of Alarm Panels


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


• Fire as an accident can be controlled by FAULT TREE ANALYSIS

• By eliminating

system faults

• By reducing system faults and failures



• 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 causes losses

– Effects of Fire Fire Risk Analysis

• Risk Containment & Risk Transfer

• Risk Containment by providing Protection Systems

• Risk Transfer by Fire Insurance


Design & Planning for Fire Safety

• Automatic Fire Detection and Alarm System

• Automatic Fire Protection Systems

• Best solutions – must be most reliable appropriate with minimum

investmentFIGHT FIRE WITH KNOWLEDGE


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



• 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 & Gas Systems

Gas Detector

Flame Detector

Fire Panel


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



Copper Wire Optical Fibre

• Case Study –Augmentation Project Implemented at IOCL – HaldiaRefinery

• Result – Cost effective for

systems covering Long Distance

Selection of Wires



• Case Study –IOCL – Panipat ,

JalandharPipelines

Division

• Result – Reliable Advanced system User Friendly Cost Effective

Integration =Gas + Fire + Flame

Detectors



• Case Study –

IPPL – Ennore

• Result – Reliable Advanced system User Friendly Cost Effective Touch Screen Based

Integration =Gas + Fire + Flame + CCTV

Detectors


Fire Protection System-Scope of Improvements

• Result – Reduces corrosion Increased Life Expectancy of Pipes Low Maintenance Cost Effective

Ordinary Pipes

Epoxy Coated Pipes

Selection of Pipes



• Case Study IOCL BPCL

• Result – Low Maintenance Cost Effective Time Saving

Regular Deluge Valves

Flangeless Deluge Valves

Selection of Deluge Valves



• 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


Fire Hydrant System for General IndustriesDifferent Components

Pump auto operation switches


• New Improvements• More efficient & reliable pumps• PLC based MCC & Cabinets• Piping material & coatings• Pipe fittings – grooved couplings• Clevis hangers


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


Fire Sprinkler Systems

Grooved couplings connected piping


• Sprinkler System design• Fast Response Sprinklers• Large orifice sprinklers• Sprinkler drop lines• Grooved Couplings

Fire Sprinkler Systems- Scope of Improvements


• Automatic Water Spray System

• For High Hazard Risks of Refinery , petrochemical risks, Oil Terminals – MVWS

• For Power Industry, Large Power Transformers – HVWS


Water Spray Systems

• Water Spray system design• Improved nozzles• Improved Deluge Valves – skid mounted• Piping material with grooved ends• Stainless Steel / CPVC pipes


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


Foam Systems

• For very large generators

• For cable trenches

• Actuated by a very reliable Detection system with Cross-Zoning


Automatic CO2 Systems

• Designed system based on flow analysis• On line weighing & alarm system• Discharge Panels

Automatic CO2 Systems- Scope of Improvements


• Control Rooms for Refineries, Power Stations

• Server Rooms for large Corporate Houses

• Must be automatic


Clean Agent Systems

Hospitals – lot of combustible

materials and patients with impaired mobility

• Automatic Hydrants• Automatic Alarms• Automatic Sprinklers• Exit Paths• Trained attendants

Hotels - lot of combustible

materials and guests in unfamiliar surroundings

• Automatic Hydrants• Automatic Alarms• Automatic Sprinklers• Guided Exit Paths• Trained attendants


Special Risks

• Fire Brigade

• Large Fire Hydrant , Pumping system and

Water Storage

• Fire Alarm –

Wireless Fire Alarms


For Large Plants and Cities



Thank You ……Your Queries

please…

Mesh Network for Wireless Nodes can cover a Steel Plant or a CityEach Node is a Transceiver – it receives and transmits and establishesa path over the shortest route to the Central Receiver in the Fire Station
