  • Occupational Exposure to Asbestos Occupational Safety

    Aug 10, 1994· In 1986, in its list of activities considered "small-scale, short-term," OSHA listed some which are neither small-scale or short-term, but were regarded as lower risk, such as roofing work. To cure this confusion, OSHA proposed, in 1990 to limit the "small-scale, short duration" exemption to a subset of renovation, removal and demolition

  • Development of testing procedure for ceramic disc filters

    Jul 01, 2011· The main principle of the test procedure applied to conventional rotary vacuum disc filters is that a small filter element, a leaf, is used for simulating a section of the full-scale filter disc. This means that the first requirement for successful tests is that the properties and structure of the leaf are exactly identical to the full-scale discs.
