Diving Helmet - Modern

Modern

An alternative to the diving helmet that allows communication with the surface is the full face diving mask. These cover the diver's face and are held onto his head by adjustable straps.

"Diving helmet" sometimes means a hard safety helmet like a workman's helmet that covers the top and back of the head, but is not sealed. These may be worn with a full-face mask to provide impact protection.

During the First World War the British Army used a few diving helmets out of water as emergency protection from mustard gas.

Famous quotes containing the word modern:

    In an age robbed of religious symbols, going to the shops replaces going to the church.... We have a free choice, but at a price. We can win experience, but never achieve innocence. Marx knew that the epic activities of the modern world involve not lance and sword but dry goods.
    Stephen Bayley (b. 1951)

    Not “Seeing is Believing” you ninny, but “Believing is Seeing.” For modern art has become completely literary: the paintings and other works exist only to illustrate the text.
    Tom Wolfe (b. 1931)

    It was announced that the trouble was not “malignant.”... It was a typical triumph of modern science to find the only part of Randolph that was not malignant and remove it.
    Evelyn Waugh (1903–1966)
