Presented to FPE March 2014

Aerosol Technology - How it Works - Codes & Standards

Definition per NFPA 2010 Standard on Aerosol Fire-Extinguishing Systems

Solid particles > 10 Microns will tend to settle to form residue Solid particles < 10 Microns will tend to remain suspended in air

Particle Median Size Comparisons: Purple-K Dry Chemical Agent ~ 20 Microns High Pressure Watermist Droplet ~ 50 to 120 Microns Aerosol Agent < 1- 2 Microns

RELEVANT STANDARDS: NFPA: NFPA 2010 Standard on Aerosol Fire-Extinguishing Systems (2010 ed.) NFPA 70 National Electrical Code NFPA 72 National Fire Alarm and Signaling Code

CEN/ISO: CEN/TR 15276-1 Fixed Firefighting Systems Condensed Aerosol ISO 15779 Condensed Aerosol Fire Extinguishing Systems

AGENCIES: UL 2775 Fixed Condensed Aerosol Extinguishing System Units CSIRO ActvFire

Aerosol fire suppression systems are designed as: Engineered total flooding fire detection and fixed suppression systems Self-activating or remote (manual) operated fixed fire extinguishers c/w high

temperature fire detection

AEROSOL SYSTEM

WHAT IT IS Total flooding system for enclosed spaces

Listed extinguishant for Class A (surface), B,

C fire hazards

Aerosol with ultra-fine solid particles mixed with and propelled by low pressure N2 inert gas

Fire detection & extinguishing system (with FACP or stand-alone)

Environmentally friendly o zero ODP, ~zero GWP, zero ALT

EPA SNAP listed as a halon 1301

replacement for normally unoccupied areas

WHAT IT IS NOT NOT NFPA 17 Dry chemical system (>20m)

NOT NFPA 2001 Clean agent system

NOT HFC halocarbon gas

NOT suffocating gas

NOT pressurized storage gas system with

distribution piping network

NOT refillable

NOT listed for Class D fires

NOT toxic when designed as a total flooding system

Aerosol Fire Suppression Technology

Aerosol Agent & Inert Gas

Actuator Signal (electric, thermal,

or manual)

How a Generator Works 1) Signal energizes Actuator 2) Agent Compound reacts with Oxidation Block, generating 3) Aerosol agent and Inert Gas pass through Cooling Block, and out generator Exit Ports 4) Stat-X Agent suspension fills hazard area, suppressing fire

Fire Tetrahedron

Primary Extinguishing Mechanism: Aerosol free radicals react with flame free radicals and interfering with chemical reactions taking place in the fire

Huge population of suspended aerosol particles < 2m with very large total surface area to absorb heat

How Aerosol Agents Suppresses Fire 1) Aerosol Agent & Inert Gas Suspension discharge fills hazard volume (particle size 1-2 micron) 2) Potassium Radicals from Aerosol Agent mix with free radicals generated by combustion 3) Potassium chemically joins with Combustion Free Radicals, interrupting the fires reaction pathway and creating Stable Molecules 4) The interrupted fire reaction pathway can no longer sustain combustion and the fire is suppressed.

Stable Molecules

Condensed aerosol agent is ultra-fine particles propelled by self-generated inert gas

Agent Effectiveness: More Efficient

21

US Naval Research Lab performance fire tests show that aerosol fire suppression systems can outperform equivalent water mist systems in extinguishment time for all sizes of fires and at a fraction of the system weight.

Cost-Effective to Own No agent level checks

or container weighing No disassembly and

vessel hydro-testing Hermetically sealed,

tough stainless steel Stable, long-lived agent

(10+ years) Keep spares handy to

Restore system fast after fire is suppressed

No waiting for resupply when at sea or remote sites
