What are types of foam used on ships?

Types of foam available for marine use:
  1. Protein base ( PF)
  2. Flouro protein foam (FP)
  3. Film forming fluoro protein foam (FFFP)
  4. Synthetic detergent foam
  5. Alcohol resistant foam-chemical fires
  6. Aqueous film forming foam ( AFFF).
  1. Water and Foam

Water and Foam fire extinguishers extinguish the fire by taking away the heat element of the fire triangle. Foam agents also separate the oxygen element from the other elements.

Water extinguishers are for Class A fires only – they should not be used on Class B or C fires. The discharge stream could spread the flammable liquid in a Class B fire or could create a shock hazard on a Class C fire.
