In Part 2 we discussed how water mist foam systems such as those utilized in our Robotic Parking Systems apply extinguishing water and foam in a fog so that the total surface area of the mixture is multiplied many times. The mixture absorbs heat, evaporates more quickly and impedes the supply of oxygen to the fire. The cooling and smothering effect is extremely effective in fire fighting.
Water mist foam systems are used to protect ships and offshore facilities such as oil platforms. Effective fire extinguishing systems are a must at sea where people cannot quickly escape in case of fire and immediate fire fighting help from outside cannot be expected.
Additionally, a key factor for fire extinguishing systems on a ship is minimizing the space and weight of materials and equipment. The water mist foam systems uses up to 85 to 90 percent less water in comparison with a conventional sprinkler system.
Since water mist foam systems came into use there has been only one ship fire on a vessel built after 1995 — the Star Princess.
This Star Princess fire is believed to have been caused by a cigarette left burning on a balcony. The fire became hot enough to melt the highly combustible balcony divides made of polycarbonate, polyurethane deck tiles and the plastic furniture. Plus, there was no detection or fire suppression system on the balcony.
After installing water mist foam fire suppression systems on ship balconies, there have been ZERO ship fires reported.
This same highly effective system is utilized in our automated parking facilities to extinguish fires before they spread or fire fighters are required on the scene.
Take a look at the photograph shown below.
By using the fine water mist foam system, potential fires are extinguished completely so it becomes unnecessary for fire fighters to enter the building to extinguish the fire.
