Control Measure – Direct Firefighting
Control Measure Knowledge
Direct firefighting is a means of extinguishing a fire, sometimes after the fire gases have been suppressed using gas cooling techniques and/or compartment boundaries have been cooled using indirect methods. However, firefighters should not become overly focused on, or distracted by, gas cooling techniques when the direct application of firefighting media is required to extinguish the fire.
Direct firefighting has the potential to generate large amounts of steam, as it involves applying a controlled amount of water directly to the seat of the fire. Firefighters should consider taking measures to ensure they are protected from steam burns and the increased heat in the fire compartment. For example, they could adopt defensive/safe positions behind substantial available cover (doors/walls) or use tactical ventilation.
Straight stream direct attack
A constant flow straight stream attack (jet) on the fire is traditionally the most common form of fire attack. In situations where a high-flow rate is required to overcome a high-energy fire, the direct attack is sometimes the only method that will achieve effective suppression and rapid knock down of the flame front.
