The Impulse Fire Extinguishing System (abbreviated IFFS) is a series of firefighting equipment that uses small amounts of water fired in high-velocity bursts to put out fires. Water droplets are shot in vaporous bursts that can travel up to 120 metres per second (390 ft/s) and provide a large surface area for cooling.
Dry chemical powder is used on all classes of fires. Dry chemical powder puts out the fire by coating the burning material with a thin layer of dust, thereby separating the fuel from the oxygen in the air. The powder also works to interrupt the chemical reaction of fire, so these extinguishers are extremely effective at putting out the fire.
Relationship of the atmosphere and ionosphere. The ionosphere (/ aɪ ˈ ɒ n ə ˌ s f ɪər /) [1] [2] is the ionized part of the upper atmosphere of Earth, from about 48 km (30 mi) to 965 km (600 mi) above sea level, [3] a region that includes the thermosphere and parts of the mesosphere and exosphere. The ionosphere is ionized by solar ...
The Pyrene Company Limited from their beginning in 1914, until 1971 when they became Chubb Fire Security Limited, were among the world's leaders in the manufacture of fire fighting equipment. The name Pyrene was epitomised by their famous 'pump' extinguisher which was installed on public transport, commercial and private vehicles throughout the ...
Fire tetrahedron. Hot, condensed aerosol fire-extinguishing agents act on both physical and chemical levels. They leverage four methods to extinguish fires, for they act on the four elements of what is known as the fire tetrahedron. These four means of fire extinction are: Reduction or isolation of fuel; Reduction or isolation of oxygen ...
The F region of the ionosphere is home to the F layer of ionization, also called the Appleton–Barnett layer, after the English physicist Edward Appleton and New Zealand physicist and meteorologist Miles Barnett. As with other ionospheric sectors, 'layer' implies a concentration of plasma, while 'region' is the volume that contains the said layer.
The preserved Art Deco gateway from the factory overlooking 'Minimax Corner' Minimax Limited was a British manufacturer of fire extinguishers founded in England in 1903. . Their unique conical fire extinguisher was known as 'The Min
