Available Capacities : 1kg, 2kg, 4kg, 6kg & 9kg
ALSO GLORIOUS AS
AFFF foam hearth extinguishers
Spray foam hearth extinguishers
FOAM DEVICE USES
Fires involving inflammable solids, like paper, wood, and textiles (‘class A’ fires)
Fires involving some inflammable liquids, like gas, diesel, and paint (‘class B’ fires)
Fires involving electrical appliances IF the device has passed the 35kv conduction check
PLEASE NOTE
Foam extinguishers don’t seem to be expressly designed to be used on electrical fires.
The 35kv conduction check is an extra preventive measure meant to safeguard users UN agency accidentally use a foam device on the associated electrical hearth – there’s a risk to employing a foam device this fashion, together with the chance of obtaining an electrical shock.
We powerfully advocate solely employing a carbon dioxide {extinguisher|fire device|asphyxiator|device} or a Dry Powder extinguisher for electrical hearth risk. p>
DO NOT USE FOAM HEARTH EXTINGUISHERS FOR
cookery fires involving oil and grease, like chip pan fires (‘class F’ fires)
Fires involving inflammable gases, like alkane and alkane (‘class C’ fires)

HOW FOAM HEARTH EXTINGUISHERS WORK
Foam hearth extinguishers add two ways in which.Firstly, they’re in the main water-based and then have an equivalent cooling impact as water extinguishers, golf stroke the hearth out by lowering the temperature.
Secondly, they contain ‘Aqueous Film Forming Foam’ (this is why they’re conjointly called AFFF foam extinguishers).
AFFF works by dyspnoeal the hearth and protection within the inflammable vapors. This prevents the hearth from re-igniting. It conjointly permits foam hearth extinguishers to place out inflammable liquid fires, by making a barrier between the liquid’s surface and therefore the flames.
PROS AND CONS OF FROTH HEARTH EXTINGUISHERS
Pros : non-toxic, non-damaging to most materials, for the most part, safe if accidentally used on electrical fires (although this is often not recommended), designed to forestall the re-ignition fires, lighter in weight than the equivalent water device.
Cons : damaging to electrical appliances. Dangerous if used on cookery fires or inflammable gas fires.
WHO WANTS FOAM HEARTH EXTINGUISHERS
Foam hearth extinguishers square measure the perfect extinguishers for premises with multiple health risks, such as:
Offices
Warehouses
Factories
Garages
Hotels
In fact, most premises take pleasure in having foam extinguishers and these square measure often suggested, particularly once paired with carbon dioxide extinguishers to be used on electrical fires.
HOW TO USE A FOAM HEARTH EXTINGUISHER
Foam hearth extinguishers the way to take away the security pin Removing a security pin
Foam hearth extinguishers ought to be used otherwise, counting on the sort of fireside.
In all cases, first of all, take away the security pin to interrupt the anti-tamper seal, and stand well back from the hearth.
FLAMMABLE LIQUIDS FIRES
Don’t spray directly at the hearth, this could cause it to unfold to close surfaces
Wherever The Liquid Blazing Is Contained, Purpose The Device At The Within The Fringe Of The Instrumentality
If it’s not contained, spray with a delicate, sweeping movement across the highest of the hearth, or against the associate adjacent surface
This Fashion The Froth Can Sink And Decide On The Highest Of The Burning Liquid
FLAMMABLE SOLIDS FIRES
Aim at the bottom of the hearth
Keep the device moving forward and backward across the flames as you spray
ELECTRICAL FIRES (NOT RECOMMENDED)
Treat an equivalent means as inflammable solids fires
Confirm You’re Standing A Minimum Of 1m Aloof From The Flames To Reduce The Chance Of Electrical Shocks
