词条 | External water spray system |
释义 |
An External Water Spray System (EWSS) is a domestic external fire sprinkler system designed to protect homes from bushfires and wildfires. While external spray systems have long been used in fire protection for buildings and facilities{{Citation needed|date=February 2009}}, EWSS refers to domestic bushfire/wildfire systems. UsageThe types of systems vary greatly from a single impact sprinkler placed on a roof, systems installed during construction with sprays on all windows and doors, and small sprays damping gutters{{Citation needed|date=February 2009}}. Some are installed using copper piping and sprays while others use common PVC piping. Usage depends on type of risk and belief of effectiveness. Copper piping is used to withstand high temperatures that may be experienced during a fire front or for higher reliability{{Citation needed|date=February 2009}} for in ceiling installations. External PVC piping is used where failure with exposure to high radiant heat is acceptable{{Citation needed|date=February 2009}}, as at the time the system is considered have "done its job". This is a matter of personal judgment. IssuesThere is a lack of scientific research regarding EWSS. Other issues that may affect the effectiveness of an EWSS:
Types
Commercial sprays designed for EWSS are available{{Citation needed|date=February 2009}}, but most systems use commonly available irrigation sprinklers/sprays. ResearchExternal spray systems for buildings are well documented for protection from fires in adjacent buildings{{Citation needed|date=February 2009}}. However, up there is little published scientific research on scientific information pertaining to the effectiveness of EWSS under varying wildfire conditions.[1] See also
