and power stations. Expansion was rapid with the wartime demand for fire-fighting equipment, and production of projectiles. A major contract was one from the Air Ministry to supply airfield crash tenders. In 1950, a new factory was opened in Ferndale, South Wales for the manufacture of fire extinguishers. The Pyrene Manufacturing Company of Canada, the CO2 Equipment Company of Canada and the American Pyrene Company were all acquired during 1953–54. Also in these years the company received commissions from the UK Atomic Energy Authority at Harwell to develop mediums for extinguishing sodium and lithium fires, which they produced under the Pyromet brand-name. The fire extinguisher manufacturer Minimax Limited, was purchased by Pyrene in 1955. During 1955 the FB5X foam making branch pipe was introduced and the Pyrene ED-HOL system in ships, which recycled the ship's own inert exhaust gases to fight fires in the hold, was developed. Over the years Pyrene fire fighting systems were installed in a number of the world's largest passenger liners including the , and . Other important contracts undertaken by the company during the late 1950s included a smoke detection system at the BBC TV Lime Grove Studios in London, smoke detectors for the Bristol Britannia aircraft, CO2 fire-fighting systems for a number of British Rail diesel locomotives, and supplying fire detection and CO2 systems for Lloyd's of London. Pyrene Panorama Ltd Pyrene Panorama Ltd was established in 1959 when Pyrene purchased the business of Panorama Equipment Ltd, which itself dated from 1941. This company was originally formed to manufacture an industrial wide-field vision safety goggle which gave rise to the name-"Panorama". Also in 1959, Pyrene acquired Roberts McClean, who in 1931, introduced self-contained compressed air breathing apparatus to the UK and these two companies merged under the Pyrene Panorama brand. Pyrene was taken over by Chubb and Sons in 1967 and continued to operate under the name Pyrene Panorama. In 1971 Chubb Fire Security Ltd was formed. In that same year a Bristol Britannia aircraft, flown by test pilot Donald Chubb, landed on a carpet of Pyrene foam at Manston. In 1976 Fireward Ltd, manufacturers since 1964 of plastic-bodied portable dry-powder fire extinguishers, also merged with Pyrene Panorama, to form the new company, Chubb Panorama. A further addition to the group in 1976 was the acquisition of Submarine and Safety Engineering Ltd, specialists in self-contained under-water breathing apparatus and diving equipment.
