Fire extinguisher CO types have the test information stamped on the cylinder, all other types get a sticker on the back of the cylinder. Once dry, the units are recharged. Unlike the UK, the US does not rebuild extinguishers and replace valves at specific intervals unless parts are found to be defective, with the exception of halon. Halon types are often given new o-rings and valve stems at every internal maintenance to minimize any leakage potential. OEM equipment must be used for replacement parts for the extinguisher to maintain its UL rating. If parts are unavailable, replacement is recommended, keep in mind
Cutting extinguisher Svenska AB was founded in 1988. The origins of the company was in water jet cutting but in cooperation with Räddningsverket (today the Swedish Civil Contingencies Agency (MSB)), the coldcut Cobra cutting extinguisher was developed in the mid-1990s with the first commercial cutting extinguisher available in 2000. In 2008, Saab acquired a 27% stake in the company. Local adoption has been enthusiastic. Of the over 750 coldcut Cobra systems delivered so far, about 150 are in Sweden and the same amount in the UK. The Cobra has also been sold to fire services in many other countries including Norway, Denmark,
