Glovebox - Hazardous Materials Work

Hazardous Materials Work

At the now-deactivated Rocky Flats Plant, which manufactured plutonium triggers, also called "pits", production facilities consisted of linked stainless steel gloveboxes up to 64 feet, or 20 meters, in length, which contained the equipment which forged and machined the trigger parts. The gloves were lead-lined. Other materials used in the gloveboxes included acrylic viewing windows and Benelex shielding composed of wood fiber and plastic which shielded against neutron radiation. Manipulation of the lead-lined gloves was onerous work.

Some gloveboxes for radioactive work are under inert conditions, for instance, one nitrogen-filled box contains an argon-filled box. The argon box is fitted with a gas treatment system to keep the gas very pure to enable electrochemical experiments in molten salts.

Gloveboxes are also used in the biological sciences when dealing with anaerobes or high-biosafety level pathogens.

Gloveboxes used for hazardous materials generally are maintained at a lower pressure than the surrounding atmosphere, so that microscopic leaks result in air intake rather than hazard outflow. Gloveboxes used for hazardous materials generally incorporate HEPA filters into the exhaust, to keep the hazard contained.

As demonstrated on an episode of the television show Mythbusters, gloveboxes can also be used to manipulate objects in a vacuum chamber.

Famous quotes containing the words hazardous, materials and/or work:

    Falling in love with a United States Senator is a splendid ordeal. One is nestled snugly into the bosom of power but also placed squarely in the hazardous path of exposure.
    Barbara Howar (b. 1934)

    Our job is now clear. All Americans must be prepared to make, on a 24 hour schedule, every war weapon possible and the war factory line will use men and materials which will bring, the war effort to every man, woman, and child in America. All one hundred thirty million of us will be needed to answer the sunrise stealth of the Sabbath Day Assassins.
    Lyndon Baines Johnson (1908–1973)

    What is history? Its beginning is that of the centuries of systematic work devoted to the solution of the enigma of death, so that death itself may eventually be overcome. That is why people write symphonies, and why they discover mathematical infinity and electromagnetic waves.
    Boris Pasternak (1890–1960)
