Foam Concentrates for Fixed Fire extinguishing Systems

Fire fighting foam suppresses fire by creating a “blanket” over the liquid fuel preventing the element (oxygen) it
needs to burn. Each type of foam concentrate has various features and benefits, applications and limitations.
Fixed foam firefighting system non-lethal in nature and can be used even when there are human present
inside the fire affected room/room. This makes the initial time duration for application of fire fighting system
shorter as compared to the CO2 system which requires evacuation of personnel before operation.
When the system is to be operated, first of all, both the linked valves are opened. The mixing of the foam
producing compounds and water is carefully metered using a automatic inductor unit. Once the mixing is done,
air under pressure in forced into the tank to produce foam. The foam is then pumped out using fire pumps. It is
of utmost importance that both, the fire pumps and compound tanks are located away from the engine room
and at a well protected area.

Our Role is to assist the Ship Operators in implementing the best Maintenance Program and follow up
anniversary intervals so that all equipment is in good working condition as necessary
*either for emergency event or for improving their Safety Management System along with the constant training
and updating of their crew onboard.
