Drip torch is used for setting backfires from a fire barrier (control line) to burn the soil cover and litter to suppress fires, as well as to burn slash on logging areas, and also for agricultural and prescribed burnings.
When a ground fire grows to reach the medium or high intensity of burning with the flame height exceeding 1.5-2 m and the line edge advancing faster than at 3 m/min, it is impossible to suppress the fire by means of a direct attack on its head due to the high temperature from the thermal radiation and fast spread of the fire. The same pertains to crown fires when forest fuels are removed with the help of backfire from natural control lines (creeks, bogs, roads, trails) or fire-lines are established through scrapping or digging to the mineral soil using digging machines or hand tools at an estimated distance for the forest fire edge depending on forest site conditions, intensity and type of the forest fire. Upon preparation of a fire barrier, a backfire is undertaken to counter the fire edge.
Drip torch is designed for starting a backfire in a safe manner and it can be used for setting fire to burn the soil cover and forest litter for fighting forest fires by means of backfires and for preventive slash burning to clean cutting areas.
Drip torch may be also used to remove forest fuels via back burning to stop the spread of a fire as well as to set preventive (prescribed) burns and to burn slash in logging areas.
The drip torch is to be used by firefighting teams of the Ministry of Emergencies, forest management units and game management units for extinguishing fire outbreaks on their own. In the active heating zone, it is very dangerous to have a drip torch on the back, so, designers of the Lessnab Company made the drip torch as safe as possible for firefighters: the cylinder with highly inflammable liquid is to be in the hands, and should an emergency occur, the device may be thrown aside.
Advantages of the product
One of its comparative advantages is that the drip torch is made of high-resistance stainless steel instead of plastic or iron used to manufacture other similar products. The drip torch is a cylinder container with a handle; it also has an aluminum fuel feed rod, a spray nozzle and a fuse with built-in asbestos filler which is hermetically sealed on the neck of the container with a lid and a nut when set in the working position. The device has a probe with a rubber seal and a nut which enables to see how much of the fuel mixture is left in the container, to regulate access of air and to ensure metered flow of the mixture to the spray nozzle. In accordance with the effective regulations on firefighting tools, the case of the drip torch has gloss red powder coating like all other firefighting equipmemt.
Only lead-free gasoline may be used for the operation of the device; prior to commencing its operation, preseason maintenance services must be provided.
It is forbidden to transport drip torches filled with fuel mixture; and it is also forbidden to ignite the fuse without prior removal of fuel residues from the outer walls of the device upon its filling.
During the filling of the container with fuels, the minimum distance from fire sources must be 10 m. If a leak is detected, the devices may not be used, the flame must be immediately extinguished, and the fuel mixture must be removed from the device. The drip torch should be stored in premises compliant with respective fire safety regulations.
