Carbon dioxide fire extinguisher. Pressurized canister containing liquid carbon dioxide (CO2) for extinguishing a fire. Since 1997, UK CO2 extinguishers are red with a black label. The pin (blue, top centre) is removed and the movable horn (upper left) is aimed at the base of the fire. Squeezing the trigger (top right) releases a cloud of CO2. The CO2 reverts to a gas at room pressure and cuts off the oxygen supply, smothering the fire. Unlike a water-containing fire extinguisher, this one may be safely used on an electrical fire. The horn must not be held during use as the rapid expansion to a gas greatly lowers surrounding temperatures.
Science Photo Library was founded in 1981 by Michael Marten, one of the authors of "Worlds Within Worlds", a book exploring different ways to observe the universe - from electron micrographs, to images of earthrise taken from the Apollo spacecraft. When Marten started receiving requests for the beautiful images in the book, he had an idea of setting up Science Photo Library.
Since then, Science Photo Library has continued to work alongside world acclaimed photographers and the leading science and medical experts to provide a central source of the best science and specialist imagery available. Although the collection started with scientific images, it has grown to encompass all aspects of science and their impact on everyday life.
