FP350 C6

3% Cost Effective FluoroProtein Foam Concentrate (FP)

FP350C6 is a cost-effective FluoroProtein (FP) fire fighting foam concentrate for extinguishing and securing flammable hydrocarbon liquid fires.

Its unique formulation is based on advanced protein foam technology. The protein base provides a tough cohesive foam blanket with high resistance to heat that quickly smothers, cools, and seals the risk. Fluorochemical surface active agents combined with the protein base increase the fluidity and fuel repellency of the foam.

  • Stable long-lasting foam blanket for unsurpassed burnback resistance and post-fire security.
  • Highly fluid foam for rapid fire knockdown and extinguishment.
  • Detergent-free for high resistance to fuel pick-up.
  • Excellent sealing action on hot metal surfaces.
  • Foam blanket re-seals when ruptured by personnel or equipment.

Performance Approvals                      

  •  FP350C6 is measured primarily against Underwriters Laboratories Standard UL 162 (7th Edition).

Environmental Impact       

FP350C6 is biodegradable and virtually non-toxic to aquatic organisms. It is based on a natural protein foaming agent and contains no harmful synthetic detergent or glycol ether.

Applications       

FP350C6 is the ideal fire fighting foam to use in situations where hydrocarbon fuels such as crude oil, gasoline, and fuel oils are stored, processed or transported. It is used extensively by major world oil and petrochemical companies for hydrocarbon storage tank fire protection. Other typical applications include process areas, road/rail loading racks, power stations, marine terminals and airports.

FP350C6 provides a vapour-suppressing foam blanket on unignited hydrocarbon spills.

Proportioning    

FP350C6 is intended for use as a 3% solution in water (3 parts concentrate to 97 parts water) at low expansion, and as a 6% solution in water at medium expansion.

It is readily proportioned using conventional foam proportioning equipment such as portable and fixed in-line foam venturi proportioners, handline nozzles/branchpipes with pick-up tubes, balanced pressure variable flow proportioners, balanced pressure bladder tank proportioners and around-the-pump proportioners.

FP350C6 should be used with air aspirating discharge devices such as low expansion branchpipes, monitors, top pourer sets, rimseal foam pourers, and foam/water sprinklers. It also produces top quality medium expansion foam when applied through medium expansion branchpipes and bund pourers.

As with any foam FP350C6 is best applied gently on to the burning liquid surface. However, its exceptional resistance to fuel contamination enables it to withstand vigorous mixing with fuel.

This makes it ideal for forceful application on to storage tank fires from ground-based mobile monitors or through base (sub-surface) injection systems.
