NIOSH Testimony on Requirements for Approval of Flame-Resistant Conveyor Belts by R. W. Niemeier, March 26, 1993.
NIOSH 1993 Mar:3 pages
These comments from NIOSH supported the efforts by the Mine Safety and Health Administration (MSHA) to promulgate a new testing procedure for conveyor belt flammability. Three areas of concern to NIOSH were presented, including the effect of frictional heating on belt fire resistance, the small sample size used in the comparison between the new small scale test and the large scale flammability test, and the issue of the relative toxicity of the products of the fire from the belt formulations required to pass the new test. NIOSH recommends that the MSHA standard should include a friction heating test. Large scale testing should continue in addition to small scale testing for comparison purposes. The health effects of combustion products from belt formulations which pass the new test should be assessed.
