      For combating large hydrocarbon fires particularly in a contained area like storage tank, foam has proved useful for its inherent blanketing ability, heat resistance and security against burn-back. 2 BY CRAIG H. SHELLEY E verY sIx months or so I reaD In eIther a news-paper clipping or trade journal about a petroleum product storage tank fire occurring in the.

    Foam - A fire fighting agent made by mechanically mixing air with a solution consisting of fresh or salt water to which a foam liquid concentrate has been added. Foam Concentrate - The liquid foaming agent as received from the manufacturer and used for mixing with the recommended amount of water and air to produce foam.   Class A foam works in several ways to increase firefighting capabilities when combating ordinary combustible fire. Similar to an industrial detergent, Class A foam concentrate reduces water surface tension. This allows the foam solution to penetrate exposed fuel cracks and crevices for more effective moisture penetration and fuel cooling.

Extinguishing foams are commonly used for extinguishing fires of flammable liquids, whereby their insulating, choking and quenching effects are exploited.

In an attempt to contain petrol fires, locally produced red palm oil was used to synthesize environmental friendly fire-fighting foam agent which is less dense than petroleum motor spirit (PMS).

The results of the experiments contained in this report suggest that, when foam is applied at a rate higher than the critical rate, its ability to combat a petrol fire is a function of its water content and of its ability to flow over the petrol surface.

Foam was produced by early compressed air foam systems that used an air compressor mounted on board the fire apparatus to aerate a solution of water and foam concentrate.

These early CAFS units were mechanically troublesome but very effective at study of mechanically produced foam for combating petrol fires.

book grass and brush fires. So he invented fire-fighting foam, which was successfully tested in several experiments in In Loran patented his invention, and developed the first foam extinguisher the same year.

The original foam was a mixture of two powders and water produced in a foam generator. • Foam does have a limited life (approximately 15 to 20 years). Therefore, disposal of fuel soaked foam will be an environmental issue. Foam Pro ducts Military aircraft are highly vulnerable to fires and explosions resulting from combat threats such as gunfire.

REFINERY AND PETROCHEMICAL PLANT FIRE PROTECTION By Barry Lee, Former Fire Protection Association Australia Board Member and National President Introduction In the midth century oil was used primarily to produce kerosene for lamps.

Later events, particularly the spectacular development of the automotive and. Fire Triangle.- The starting of a fire involves three elements - fuel, oxygen, and ignition temperatures. These elements may be compared to the three legs of a triangle (fig.

1), for fire cannot occur until all three are brought together. Figure 1. - Fire triangle The following is a common cause of fires in terms of the fire triangle. foam and of Tuve [5] on mechanical foams for he1 fire extinguishment. Welker et al. [6] carried out work on effectiveness of fire control agents on chemical fires, highlighting future tests that should establish scaling parameters to allow use of smaller surface areas for the comparative effectiveness tests.

Types of Foam particular qualities: • Protein foam, one of the earliest foams, is produced by the hydrolysis of protein material such as animal hoof and horn. Stabilizers and inhibitors are added to prevent corrosion, resist Fire Fighting Foam Principles and Ethanol-Blended Fuel.

Regular Protein (RP) foam is the direct descendant of the original protein firefighting foam that was first developed in the s.

RP foam has slow knockdown characteristics but provides superior. Firefighting foam has been around for many years, from the powder foam to protein foam to the synthetic foam in use today.

Originally designed to extinguish simple hydrocarbon-based fuel fires, today’s foams can be used on Class A fires and alcohol-based fuel fires and, of course, foam is still used for hydrocarbon fuel fires.

flammable liquid (Class B) fires. Foam has also been used successfully on Class A fires where the cooling and penetrating effect of the foam solution is important. Foam Concentrate Water Air Mechanical Agitation FOAM TETRAHEDRON Suppresses Vapor FUEL Excludes Oxygen VAPORS Cools 2.

MID-EXPANSION – Expansion ratio from to Medium. The foam they produced was not stable. Desania and Yandisa went on to produce a product which uses vinegar, water, sodium bicarbonate and dish-washing liquid for a foaming agent. This product can be used on Class A fire (ordinary com-bustibles such as wood and cardboard) and Class B fire (flammable liquids such as petrol and paraffin).

This is necessary, as some foam concentrates are not suitable for use on the Polar solvent/Alcohol type fuel spills or fires. Following is a list of mechanical foam concentrates that are the most common types currently used by fire fighters today. Aqueous Film Forming Foam (AFFF) Alcohol Resistant (AR-AFFF).

“The light, voluminous foam blanket produced by our high-expansion foam systems can quickly obtain great heights, reaching elevated flammable materials (such as on storage racks). The foam blanket efficiently transports small amounts of water to the fire, encapsulating the flammable vapors and causing suppression and extinguishment.

fires occur at sea they must remain onboard and cope with these incidents to the best of their own abilities. These efforts, often because of lack of knowledge, training, and experience, have produced less than satisfactory results and at times have resulted in tragedy.

Because of the many technological advances in ship design and operation.Firefighting foam is a foam used for fire role is to cool the fire and to coat the fuel, preventing its contact with oxygen, resulting in suppression of the -fighting foam was invented by the Russian engineer and chemist Aleksandr Loran in The surfactants used must produce foam in concentration of less than 1%.

Other components of fire-retardant foams are.supply and manufacture of fire fighting foam concentrates and the laboratory testing of produced foam and foam concentrates.
