BOC FS125The Fire Extinguishing Solution

Background - Montreal Protocol

• With the introduction of the Montreal Protocol in 1987, Halon is no longer available in most countries and alternatives must be found.

• Halon will be phased out by 2010 and suitable replacements are required for both existing installations and new projects.

• The replacement agents are required to be more environmentally friendly

• Current alternatives for Halon 1301 include both HFC‟s and Inert gas systems such as FM200, Argonite, Inergen, etc.

BOC Introduces…BOC FS125

A patented Product manufactured by Safety Hi – Tech, Italy• A mixture of Pure HFC 125 & Additive

• Chemical name : Pentaflouroethane (99.85%) & „d‟ Limonine (0.15%)

• Extinguishes the Fire by Chemical reaction & Cooling effect.

• Additive increases the Extinguishing performance compared to Pure HFC 125 due to additive.

• Additive reduces the production of decomposition – by – products.

•Can operate from a temperature of - 18 0C to +54 0C

NAF S 125® Extinguishing and Design Concentrations in accordance with NFPA 2001 (2004 Edition)

Extinguishing concentrations:

Class A fires* (wood crib, sheets of ABS, PMMA and Polypropylene plastic): 6,7 % v/v - 364 g/m³ @ 20 °C

Class B fires (0,25 m² heptane pan): 8.7 % v/v - 483 g/m³ @ 20°C

Design concentrations:

Class A fires*: 8,0% v/v - 441 g/m³ @ 20 °C

Class B fires : 11,3% v/v - 645 g/m³ @ 20 °C

*Class A fuels represent most common applications protected by halocarbons, such as computer rooms, control rooms, electrical rooms, archives and museums

NAF S 125® is similar to Halon 1301

It distributes quickly and homogeneously inside the protected enclosure, reducing extinguishing times, decomposition by-products and damage

Being “Lighter” than Halon 1301, it maintains the concentration even in the upper part of the protected enclosure, avoiding stratification and possible re-ignition

The Difference with BOC FS125

BOC FS125 has better extinguishing performance

- 20% Less agent required than FM200 (HFC227ea)

- 32% Less agent required than FE13 (HFC 23)

•BOC FS125 has been approved to operate from a temperature of -18 0C to +54 0C

•The addition of d-Limonene increases the extinguishing performance compared to pure HFC 125

• d-Limonene reduces the production of any decomposition by-products

The NAF S125 blend is patented because it contains an innovative detoxifying additive

Advantages of NAF S125 versus Inert Gases

• Fewer cylinders are needed to extinguish the same fire compared to inert gas systems

• Less cylinders means:• Lower system cost • Less storage space required• Low maintenance costs

• Fast extinguishment (Discharge in 10 seconds compared to 60 seconds for Inert gases)

• Faster discharge = Less damages caused by the fire
