An article in the 'Evening Chronicle' appeared in 1928 stated that it was a legal necessity for motorists to have their garages equipped with fire extinguishers or to empty their petrol tanks each time they put their cars away. In 1929 the Duke of York's household was protected by Read and Campbell extinguishers and precise instructions on fire drill procedure were printed. In the same year the Athenaeum Club, the National Gallery and the Victoria and Albert Museum were equipped with Read and Campbell extinguishers. During the Second World War, Read and Campbell continued to manufacture extinguishers, both for civilian and military use. In 1948 the company was awarded the contract for supplying extinguishers to London Transport. The Read and Campbell copper shell extinguisher was installed in the Royal Automobile Club in London. This pure copper extinguisher was very popular where appearance was important. The business was acquired by Chubb and Sons in 1964 but continued to operate from Horsham as Read and Campbell until the formation of Chubb Fire Security Limited in 1971.
