ENVIRONMENTAL IMPACT
PYROSHIELD agent is a mixture of two naturally occurring gases; nitrogen and argon. As PYROSHIELD agent is derived from gases present in the earth’s atmosphere, it exhibits no ozone depleting potential, does not contribute to global warming, nor does it contribute unique chemical species with extended atmospheric lifetimes. Because PYROSHIELD
agent is composed of atmospheric gases, it does not pose the problems of toxicity associated with the chemically derived Halon alternative agents.
PRODUCT DESCRIPTION
The PYROSHIELD Fire Suppression System, manufactured by AST (PTY) LTD, is an engineered system utilising a fixed nozzle agent distribution network. The system is designed and installed in accordance with the National Fire Protection Association (NFPA) Standard 2001, “Clean Agent Fire Extinguishing Systems”. When properly designed, the PYROSHIELD system will extinguish surface burning fire in Class A, B, and C hazards by lowering the oxygen content below the level that supports combustion.
PYROSHIELD agent is a mixture of two inerting (oxygen diluting) gases: 50% nitrogen, 50% argon. PYROSHIELD gas extinguishes fire by lowering the oxygen content below the level that supports combustion. When PYROSHIELD agent is discharged into a room, it introduces the proper mixture of gases that still allow a person to breathe in a reduced oxygen atmosphere. The normal atmosphere in a room contains 21% oxygen. If the oxygen content is reduced below 15%, most ordinary combustibles will cease to burn. PYROSHIELD will reduce the oxygen content to approximately 12.5%.
Basic Use
– The PYROSHIELD system is particularly useful for suppressing fires in hazards where an electrically non-conductive medium is essential or desirable; where clean up of other agents present a problem; or where the hazard is normally occupied and requires a non-toxic agent.
All normally occupied or unoccupied electronic areas where equipment is either very sensitive or irreplaceable
