Where is the Mulsifyre method used?
Oil Fire
Wood Fire
Gas Fire
Paper Fire
Oil Fire
Quick Summary: The Mulsifyre system is a specialized fire protection system designed to extinguish oil fires by emulsification. It works on the principle of turning the oil surface into a non-combustible emulsion using high-velocity water sprays.
The Mulsifyre system is a specialized fire protection system designed to extinguish oil fires by emulsification. It works on the principle of turning the oil surface into a non-combustible emulsion using high-velocity water sprays.
E=VwaterVoil — Emulsification efficiency ratio
The system utilizes discharge projectors that deliver water in a high-velocity, fine atomized spray (mist). When this mist impacts the surface of the burning oil, it creates an oil-in-water emulsion. Since the oil is emulsified and the water spray provides cooling and oxygen displacement, the combustion process is terminated effectively.
Specifically designed for Class B fires (liquid hydrocarbons).
Uses high-pressure water projection to create a stable emulsion.
Commonly installed in oil-filled transformers and switchgear cubicles.
The process relies on the physical mixing of water and oil droplets.
Rapidly extinguishes large surface area oil fires.
Reduces heat intensity via latent heat of vaporization.
Non-toxic and environmentally safe extinguishing medium.
Requires high water pressure to be effective.
Not suitable for fires involving delicate electronic equipment due to water damage.
Risk of conductivity if used near energized HV components without proper insulation/clearance.
Power Transformers
Oil storage tanks
Switchgear rooms
Turbine lubrication oil systems
Mulsifyre is a trade name frequently associated with Grinnell Fire Protection systems.
Option B (Wood Fire) typically requires Class A foam or water jets, not emulsification systems.
Option C (Gas Fire) usually requires dry chemical powder or CO2 to avoid explosive flashback.
A is correct — The Mulsifyre method is a specialized fire suppression technique used specifically to extinguish oil fires by creating a non-combustible emulsion.
In power systems, remember that Mulsifyre is standard for oil-filled transformers, while CO2/Halon systems are preferred for control rooms where water damage must be avoided.
