Water remains one of the most effective fire-extinguishing agents we have, from the humble fire bucket to today’s more sophisticated water fire extinguishers. Water extinguishers should only be used where they work best, on Class A fires, sometimes called ordinary combustible fires. Paper, wood, fabrics, furniture, indeed most things you’ll have stored in your home or office, will provide the fuel for a Class A fire. Water conducts electricity, so water fire extinguishers should never be used in a situation where there are live electricity cables or electrical appliances. They are best paired with another extinguisher that is suitable for use on electrical equipment fires, such as a CO2.  

Fire hose reels are located to provide a reasonably accessible and controlled supply of water to combat a potential fire risk. The length of a fully extended fire hose is between 18 and 36 meters with a diameter of 13 or 19mm internal diameter. These appliances are designed to deliver, at a minimum, 0.33 litres of water per second. A control nozzle attached to the end of the hose enables the operator to control the direction and flow of water to the fire. All fire hose reels come with a unique ball or gate valve shut off device, a plastic or solid brass hose reel nozzle, and mounting bracket.  

  Foam fire extinguishers have come a long way in 30 years. The original foam was thick, gloopy and smelled appalling, due to its high animal protein content. Modern Aqueous Film Forming Foam (AFFF) fire extinguishers are another breed altogether, one of the best all-round units available. Foam extinguishers are red with a cream panel above the operating instructions. Foam is extremely effective on Class A fires, involving paper, wood, etc, so they are a good choice for a general office or location fire extinguisher. They are particularly great on man-made furnishings, where the fibres in the fabrics might otherwise liquify in the heat of the fire. When used on flammable liquid fires (Class B), the foam forms a film that prevents re-ignition of the flammable liquids by sealing the liquids away from oxygen in the air.

  CO2 (Carbon Dioxide) fire extinguishers are the only fire extinguishers recommended for fires involving electrical equipment. CO2 is safe to use on and around electrical equipment, as the gas itself is non-conductive, and once used, there is no sticky foam or messy powder left behind. They are also effective on Class B fires (flammable liquids). Carbon dioxide fire extinguishers are painted bright red with a black panel above the operating instructions. They have a distinctive horn-shaped nozzle at the side on the smaller models with 5 kgs and above having a hose and horn. CO2 fire extinguishers should not be used on Class D fires, involving flammable metals. The CO2 gas can react with some volatile metals, and as with other non-D rated extinguishers, can also blow burning metal over a wide area, making the situation worse. CO2 extinguishers are the most popular with film units, due to the low secondary damage caused when used. If paired with a foam extinguisher, 4 out of 5 fire categories are covered.

Dry powder fire extinguishers are excellent all-round fire extinguishers, often recommended for use on vehicles and in homes. All powder fire extinguishers are red with a blue panel, are either ABC or BC rated and are safe to be used on fires involving electrical equipment. Dry powder extinguishers are not suitable for use in enclosed spaces such as offices, hotels, schools, etc, as the fire-fighting agent creates a cloud that can obscure vision. The contents may also create breathing problems. Unfortunately, the additional benefit of ABC rated dry powder fire extinguishers being able to tackle flammable gas fires also has a major drawback. Ammonium phosphate can react with any water present to form phosphoric acid, which is corrosive and can seep into even the slightest cracks in equipment. For this reason, dry chemical ABC rated fire extinguishers should not be used on sensitive electrical equipment such as computers, switch installations, scientific instruments or aircraft, if other fire extinguishing options are available. In the event of an emergency when only a dry powder fire extinguisher is available, however, always remember that electrical equipment can be replaced, a human life cannot.

  The landing valves are designed to be an efficient part of the total hydrant system. These are meant to be freeze-resistant and applicable to fire situations. The quality standards are dedicatedly met with, as per Govt. regulations. These models could also come in models that regulate water pressure through the outlet with varying pressure through the inlet, as required in typical installations.
