Introduction to Clean Agent Systems

Where did we come from?

How did we get here?

Halon 1301

• In 1947 that research by the Purdue Research Foundation and the U.S. Army resulted in the discovery of two effective low toxicity Halons: 1211 and 1301.

• It was introduced as an effective total flooding gaseous fire suppression agent in the 1960s

– aircraft, – mainframe computers, – telecommunication switching centers

• Halon 1301 is also used in the F-16 fighter aircraft to prevent vapors in the fuel tanks from becoming explosive. Upon entering areas with possible unfriendly fire, Halon 1301is injected into the fuel tanks for one-time use.

Montreal Protocol

• An international treaty designed to protect the ozone layer by phasing out the production of a number of substances believed to be responsible for ozone depletion.

• The treaty was opened for signature on September 16, 1987, and entered into force on January 1, 1989. Approximately 196 states have currently signed it.

• The Montreal Protocol required that all production of new Halon cease by January 1, 1994. Recycled Halon and inventories produced before January 1, 1994, are now the only sources of supply.

Support and Availability

• Number of existing Installed Halon 1301 systems is not clear

– HTOC report - Approx. 76,200 installed systems

• Manufacturer support across all companies is waning

• Halon 1301 availability in future is uncertain.– Plentiful vs. limited supply (3 to 20 year supply?)– Surplus from Europe sustaining current demand– US base of Halon 1301 demand is consistent regardless of

price per lb.

Understanding the Need for Clean Agents

Choosing the Kidde Engineered System

• Business interruption– Recent events prove proactive risk management

saves money– Cost of downtime often astronomical

System vs. Agent

• Agent– One component in the overall suppression (or

protection) system– Typically viewed as the most important component– Often sole focus of decision making or specification

creation

System vs. Agent

• System– Incorporates dozens of components– Detection system(s)

- Conventional / intelligent / HSSD / water / heat– Control system(s)

- Fire alarm / suppression release / monitoring– Suppression system(s)

- application specific

Total Flooding Suppression Systems

• A system consisting of an agent supply and distribution network designed to achieve a minimum agent concentration through the hazard volume

Local Application Suppression Systems

• A system consisting of a supply of extinguishing agent arranged to discharge directly on the burning material.

• Concept derived from NFPA-12: Carbon Dioxide

• Currently no Kidde Fire System carries approval or listing for Local Application

– Design Challenges– Approval Procedures

What are HALOCARBON Agents?

• NFPA 2001: An agent that consists as primary components one or more organic compounds containing one or more of the elements fluorine, chlorine, bromine, or iodine.

• Typically heavier than atmosphere… descending layer interface which requires room integrity to maintain concentration levels

• Electrically non-conductive HF production when in contact with a flame sheet

• Visible obscuration during discharge

• Most are suitable for Class A, B, and C Fires

What are INERT Gases?

• NFPA 2001: An agent that contains as primary components one or more of the gases helium, neon, argon, or nitrogen. Inert gas agents that are blends of gases can also contain CO2 as secondary component

• Same density as the atmosphere…will mix with the air and hold concentration levels

• Does not conduct electricity

• No toxic by-products when exposed to heat

• No visible obscuration during discharge or residue after discharge

• Suitable for Class A, B & C Hazards. Stored and Discharged as a Vapor (Gas)

Fire Protection At-A-Glance

• The marketers of IG-55 claim that CO2 is not required to help a person breathe in a >12% O2 environment, as concentration levels are below the NOAEL.

• US EPA position

FE-25 (HFC-125)

“Rumors” to the next best clean agent

• It’s a drop in replacement for 1301

• It’s better

• It is very “green”

• It does everything

• It’s cheaper

• It can . . .

Some History

• In the early 90’s there were a lot of births

• One was named FE25

• At birth FE-25’s parents said:– “…the higher concentrations required to effectively extinguish fires

can, based on our recently completed testing, lead to cardiac

sensitization problems. Therefore, FE-25 (HFC-125) is no longer

considered a viable alternative for Halon 1301 in occupied spaces.

– Dupont Fire Extinguishants News, Volume 1, No.3, Fall 1992

Some interesting facts

• The exact same chemical that was introduced in the early 90’s

• It can be used now because of change in NFPA standards

• It can be used on Class A fires in occupied spaces

• It can not be used on Class B fires in occupied spaces

• It can be used as a “drop in” replacement for 1301 in very limited circumstances

FE-25 Strengths

• It uses less agent, for Class A hazards, than is necessary with FM-200

• It is UL Listed and FM Approved

FE-25 Weaknesses

• Single source supplier

• Toxicological issues

• Field recharge capability

• Liability issues
