TECHNICAL INFORMATION
SYSTEM DESIGN AND CONFIGURATION
In case of fire in a container, the NFF XFLOW water mist lance and the water monitor can be used together or independently.
The water mist lance tool case contains a battery operated drill, a fire hose and the lance itself.
The equipment can easily be carried, mounted and operated by one person. The lance is connected to the fire main using the hose in the tool case, and water is released by pushing the valve handle. With the drill, it is easy and fast to drill a hole in the container wall, preferably quite high up on the wall.
The lance is then inserted in the hole, and the groove in the fixing sleeve fastens in the container wall. It can operate unattended as long as needed.
The monitor can be placed on deck or other horizontal surface without any straps or fastening devises. It is however fitted with a strap that can be used if the ship is rolling or pitching in heavy seas.
The monitor is connected to the fire main with a standard fire hose, and start operating as soon as the hydrant valve is opened. The angle of the water jet is easily adjusted by a turning wheel, from 0° to 90%, and the direction is set by turning the monitor. The monitor stays stable by itself, and can operate as long as needed unattended.
Extinguishing fire using water
The NFF XFLOW water mist system creates a mist of fine water droplets. Droplets in variable sizes circulate in the airflow, suppressing the supply of oxygen and absorbing the heat energy, and thereby breaking the chain of combustion.
Water is an effective agent for fire fighting as it is readily available and environmentally friendly. When water is added as mist it is most efficient at reducing and dissipating heat and thereby controlling, suppressing and extinguishing a fire.

RULES AND REGULATIONS
Both the NFF XFLOW mobile water monitor and the NFF XFLOW water mist lance are type approved according to IMO regulations under SOLAS II-2/10.7.3 and the mobile monitor is tested and approved to meet the SOLAS regulations IMO MSC.1/ Circ. 1472.
The new regulation states that vessels carrying containers on or above the weather deck, constructed on or after January 2016 shall carry at least one water mist lance. Regulation states that vessels designed to carry five or more tiers of containers on or above the weather deck, shall carry a number of mobile water monitors in addition to the water mist lance(s):
Min 2pcs when ship breadth <30 meters
Min 4 pcs when ship breadth >=30 meter
The water mobile monitor is subject to onboard testing and approval to verify that the water jet of the mobile monitor reaches the top tier of containers when all required monitors and fire hoses are operated simultaneously.
Regulation background
Ships are constantly growing in size, so are container ship fleet sizes. Thus, the number of fire accidents on board container ships is also increasing. As a result of the Formal Safety Assessment (FSA) provided to the Marine Safety Committee (MSC) at the IMO, it was agreed that fire protection of new cargo ships with containerised cargo on deck should be improved. Therefore additional firefighting equipment is required to be carried on board as specified by SOLAS reg. II-2/10.7.3.
