Subscribers to the Council data sheet maintenance service will receive a copy in the next quarterly mailing. Introduction 1. Industrial dusts, mists, and fumes, their hazards and their con trol, are discussed in this data sheet.' The general principles presented can be applied to evaluate most .in dustrial situations involving these air contaminants and to determine the need for controls. This data sheet is intended to guide employers, plant safety engineers, personnel manogers. and supervisors. 2. A plant manager who believes that he has a toxic or irritating dust problem should consult u competent industrial hygienist. Such help may be obtained from his own company, insurance .carrier, private consul tants, or ' state - health or labor agency. 3. To protect the health of em ployees who work where a dust, fume, or mist created by a manufac turing process is released into the at mosphere. a control program may be required. In such a case, three steps must be taken: a. The properties ofthc specific dust. ` fume, or ' mist and its possible physiological effects on employees must be ascertained. ~Thii data sheet coven toxic and itrilaling air contaminants encountered In industry..It docs not include a discussion of the explosive properties of such air borne particulate matter. . This deto *h**f Is on* of o sarltt published by th* Nctlonot Softly Council, reflecting experience from many sources. Not every accept able safety procedure in this . field It necessarily included. TWi data sheet should net bo con fused with American Safety Stand ards, federol taws, insurance re quirement!, stale lowi. rules; reg ulations or municipal ordinances. b. The particular exposure must he evaluated by dun counts or by . chemical analyses of air samples. . and a step-by-step analysis of the operations must be made to find the areas where employees are ex posed to hazardous amounts of the material. The operational anal ysis also should determine how the dust. fume, or mist is dispersed. Appropriate methods of control must be provided where indicated. The type and extent of controls wilt depend upon the physical, chemical, and toxic properties of the dust. fume, or mist, thq evalua tion made of the exposure, and the operation that disperses the con taminant. The extensive controls needed for lead oxide dust, for example, would not be needed for limestone dust, since much greater quantities of limestone dust can be tolerated. 4. Except for the skin diseases, most occupational diseases are ac quired by inhalation of material. Lung,tissue is byfar the most efficient medium the body possesses for ab sorbing materials. In addition, the surface area of this lung tissue aver ages 53 square meters or about 590 square feet. 5. Certain dusts that reach the lungs can pass directly into the blood stream and be absorbed over a fong period of time. Others may stay in the lungs and set up local irritant or dam aging action. .. _ 6. Toxic and irritant dusts can also be ingested in amounts that may cause trouble. If toxic dust swal lowed with food or saliva is not sol uble in body fluids, it is eliminated directly through the intestinal tract. Toxic materials that are readily sol uble in body fluids can be absorbed in (he digestive system and picked up by the blood. 7. A third way in' which toxic and irritant substances may enter'the system is skin absorption. Many or ganic compounds, such as TNT. cy anides. and most aromatic amines, amides, and phenols, can produce systemic poisoning by direct contact with the skin. Contact of toxic and irritant dusts with the skin also may result in skin irritation. S. As compared to' inhalation. National Safety Nows, Juno 1963 . 89
