This testimony before the Subcommittee on Environmental Problems Affecting Small Business concerned the role of NIOSH in helping to establish safety in the workplace, including those operated as small businesses. The current appropriation for NIOSH was 36.5 million dollars, with 702 positions. Administrative headquarters were located in Rockville, Maryland with the main research/training/technical assistance facility being in Cincinnati, Ohio, and a field station in Salt Lake City, Utah. At Morgantown, West Virginia the research activities concerning with safety in coal mining were carried out. A wide range of research projects were conducted in house or through grants concerning the effects of exposure to toxic substances and harmful physical agents and to combinations of exposures. Instruments were developed to monitor levels of environmental hazards in the workplaces and develop personal monitoring devices for individual workers. The Health and Safety Act of 1970 required that research be conducted and industry wide studies be made on the effects of chronic or low level industrial exposures. A 2 year national occupational hazard survey was underway to assess potential health hazards in a sample of 8,000 representative workplaces to provide a national estimate of industrial health hazards based on Standard Industrial Classification codes. The development of Criteria Documents was also discussed, along with the interest of NIOSH in the educational aspect of safety for the worker, the employer, and the public.
