  1. Fire Suppression Systems AssociationPRESENTS: S.H.A.P.E. presented by Your name here Your company here

  2. Special HazardsAwareness Promotion & Education

  3. Special Hazards • Definition: • Any area containing equipment or processes of exceptionally high value. • Any area containing unique or irreplaceable assets. (Museums, Art Galleries, Records Storage) • 3. Any area or process where the revenue produced is of greater value than the equipment itself.

  4. CLEAN AGENT FIRE SUPPRESSION SYSTEMS • Definition: • 1. A Fire Suppression System whose means of extinguishment does not cause damage in addition to that which was caused by the fire itself.

  5. Fire Protection Systems • Safety • Occupants, respondents, surroundings • Damage Control • Buildings, equipment, data • Business, operations, revenue

  6. Special Hazards • High value assets • Areas where water is not appropriate as the first and only means of fire protection

  7. Special Hazards • FACT: Fire Sprinklers Save Lives • FACT: Fire Sprinklers are an essential part of a building’s total fire protection • FACT: Fire Sprinklers protect STRUCTURES – NOT CONTENTS • FACT: Fire Sprinklers meet MINIMUM Code Requirements

  8. Special Hazards • Risks of improper fire protection • Downtime • Business closure • Insurance coverage • Legal liability • Personal injury

  9. Special Hazards • Data processing • Rooms and Subfloors • Tape vaults • Robotic storage units • Telecommunications • Switch facilities • Cell sites • Battery storage

  10. Special Hazards • Healthcare • MRI / CT / Radiography • Data and Records storage • HIIPA regulations • Historic/Cultural Properties • Libraries • Museums • Art galleries • Vaults and Safes

  11. Special Hazards • Power Generation • Turbine enclosures • Generator sets • Electrical/motor control rooms • Marine • Machinery spaces • Pump or generator rooms • Cargo holds

  12. Special Hazards • Industrial Applications • Process control rooms • Motor control rooms • Flammable liquid storage • Specialty Applications • In-cabinet • CNC Machines • Performance vehicle • Fume Hoods

  13. Special Hazards Systems • Five types of systems • Foam • Carbon Dioxide • Dry Chemical • Water Mist • Clean Agents

  14. Foam Systems • How they work • Separates fuel from oxygen • Blankets fuel creating barrier • Cools fuel • Suppresses flammable vapors

  15. Foam Systems • Types of Systems • Protein foam • Fluoroprotein foam • Aqueous film forming foam (AFFF) • Applications • Airports, refineries, manufacturing, etc… • Flammable liquids

  16. Carbon Dioxide Systems • The original gaseous suppression system: • Used since 1910 • Rapid discharge and extinguishment • No clean-up • Will not damage electronics • Toxic at design concentrations

  17. Carbon Dioxide Systems • Applications • Best suited for unoccupied areas • Commonly used in “Local Applications”

  18. Carbon Dioxide Systems • Several System Types • Total flooding • High pressure cylinders • Low pressure, refrigerated bulk tank • Local Application • Hose reel applications

  19. Dry Chemical Systems • Ideal for industrial applications • Coats the surface of fuel material • Separates fuel from oxygen • Reduces chance of re-flash

  20. Dry Chemical Systems • Applications • Flammable liquid storage areas • Dip tanks • Mechanical rooms • Exhaust ducts • Quench tanks • Coating equipment

  21. Water Mist Systems • Water based technology in special • hazards fire protection • Fine water droplets turn to steam • Increases in volume 1,760 times • Extinguishes by heat absorption and localized oxygen displacement

  22. Water Mist Systems • Applications • Turbine hoods • Flammable liquid storage • Machinery rooms • Incinerator installations • Emergency generator rooms • Switch gear rooms • Engine rooms

  23. Clean Agent Systems • Waterless technology - objectives • Detect and suppress fires rapidly • No additional damage to equipment • Eliminate down time for unaffected equipment • Environmentally friendly • Require no clean-up • Safe for Personnel

  24. Clean Agent Systems • History Lesson • Halon was the standard for Clean Agent Fire Suppression • US EPA banned production of NEW Halons as of 12-31-93 • US EPA Developed “SNAP LIST” • (Significant New Alternatives Policy) • 21 Agents/Compounds approved • Six Agents currently available in US

  25. Halons • Halon 1211 and 1301 were highly • successful suppression agents • Fast suppression • Minimal damage • Br and Cl are ozone depleting • Production banned by EPA • Only available in recycled form • Limited supply

  26. US EPA - SNAP • Significant New Alternatives Program • Program evaluates new suppression agents • Human health considerations • Environmental considerations • Approved agents: • Have similar suppression qualities as Halon • Non-ozone depleting • Not harmful to people • Not harmful to the protected space

  27. NFPA 2001 • Standard on Clean Agent Extinguishing Systems • Revised in 2004 • Safety • Components • System Design • Inspection • Testing • Maintenance

  28. The Next Generation • Clean agents for the 21st Century • Fluorine based agents • Chlorine and Bromine generally avoided • Zero ozone depletion potential • Heat absorption mechanism • Inert gas agents • Various combinations of naturally occurring inert gases (N2, Ar, CO2) • Oxygen reduction mechanism

  29. NFPA 2001 listed agents (abb)

  30. NFPA 2001 listed agents • Fluorine based agents • Suitable for class A, B, C hazards • Primary mechanism is removal of heat (NOT oxygen depletion) • Design concentrations: 4%-9% v/v • Safe for occupied areas • Zero ozone depletion potential
