FIRE TESTS OF SHIPPING CONTAINERS AND COBALT-60 TELETHERAPY HEAD
Fire tests of several isotope shipping containers and a cobalt-60 teletherapy head were conducted under controlled conditions equivalent to similar tests conducted upon record protection equipment such as safes and filing cabinets. Fire test exposures were limited to 1 hr maximum time and test furnaces were controlled to produce interior temperatures in accordance with the Standard TimeTemperature Curve adopted by United States Fire Protection authorities, also as set forth in proposed Part 72 of Federal Regulations. The lead-shielded devices failed to comply with the proposed Regulation because of melting of the lead shielding, rupture of the steel body shells enclosing and supporting the shielding material and consequent loss of the shielding media. The all-steel shipping container, which can be used for the shipment of liquids, failed by destruction of the sealing gaskets. (auth)
