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

The PBPK model introduces a new scientific approach to determine safe exposure limits to halocarbons
The PBPK model is specified in the NFPA 2001 Standard, Edition 2004
At the concentration of use NAF S 125® allows a safe exposure time limit of 5 minute

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
