Firelance is designed to give firefighters an effective tool for knocking down fuel restricted compartment fires and oxygen restricted fires with minimal water usage, while remaining outside of the compartment, safe and sound, when operating the Firelance.
The main objective of Firelance is to utilise as much of the heat as possible by wetting all burning surfaces within the compartment, creating steam and thus effectively absorbing large amounts of energy with low water usage.
Firelance uses around 107 L/Min, at 10 bar pressure. It produces a plane of water around its head, which rotates around its own axis. Firelance’s application of water fog and direct stream inside a burning compartment effectively utilizes the four extinguishing mechanisms of water.
- Cooling of fuel and potential fuel to stop the pyrolysis
- Decreasing the oxygen percentage (inerting) with water in the form of steam
- Cooling of hot fire gases
- Absorption of radiant heat
Given its features, it is highly effective at combating flashovers and fully developed fires.
