Polycarbonate spray nozzle with handle for 2.5" hose, QST (Quebec) thread, fog stream, full stream or complete shut-off

Fog Nozzle With Handle for 2.5 in Hose, QST (Quebec) Thread

The nozzle with handle for 2.5 in hose is moulded in polycarbonate and fitted with a QST thread, the standard threading in Quebec. It projects a fog spray, a full stream or closes completely, making it a versatile tool for firefighters. The fog stream quickly brings fires under control by creating a water mist that cools the affected area, reduces smoke and lowers the amount of oxygen available to the fire. The nozzle also creates a water barrier that protects the responder from flames and heat. Its handle makes it easier to grip and helps the user move forward. An economical nozzle, it is sold individually.

Polycarbonate was chosen for its light weight and impact resistance : it lightens the nozzle without sacrificing strength, which makes handling easier during a prolonged response. The maximum flow reaches 150 U.S. gallons per minute at 100 psi. Note : this nozzle covers class A and B fires only and is not ULC approved.

Benefits of the 2.5 in QST Fog Nozzle

Beyond its versatile stream, this nozzle stands out for its Quebec threading and its handling.

Three Modes: Fog, Full Stream, Shut-Off

The nozzle projects a fog spray, a full stream or performs a complete shut-off, allowing the stream to be matched to the situation right at the nozzle.

QST Thread and Ergonomic Handle

The QST thread matches the Quebec standard, and the handle makes it easier to grip and helps the user move forward during fire attack.

Thread Types of 2.5 in Hoses in Canada

In Canada, the threading of 2.5 in hoses varies by province or territory. The following table presents the main thread codes, their region of application, their outside diameter (ODM) and their number of threads per inch (TPI) :

Restrictions and Special Features of the Fog Nozzle

QST fog nozzles are not suitable for all fire types. In particular, they should not be used on combustible metal fires such as magnesium, titanium, sodium and potassium. It is important to know how to handle a fog nozzle correctly and not to fight a fire if you are unsure of what to do. QST threading is found mainly in Quebec, but you may sometimes come across equipment with other thread types.

Application Tips for the Fire Nozzle

Here are some general tips for using a fire nozzle safely and effectively :

1. Make sure the hose is connected to a reliable water source and that the pressure is sufficient to supply the nozzle.
2. Aim at the base of the flames rather than the flames themselves, to put out the fire faster.
3. Use the right stream type : a full stream to reach a distant area, a diffused stream to cover a wider area.
4. Keep a safe distance from the fire to work efficiently and reduce the risk of injury.
5. Be ready to adjust your strategy if the situation changes (rapid spread, position change).

Other QST Nozzles and Maintenance

Equivalent versions exist for other provinces, available on request through customer service : IBPL-250CSA (CSA thread, Ontario), IBPL-250BAT (AMA/BCT threads, Western Canada and British Columbia) and IBPL-250NS (NS thread, Nova Scotia). For maintenance, clean the nozzle after each use with a soft, damp cloth, without harsh chemicals or abrasives, and store it in a dry place away from direct light and extreme temperatures.
