Also, samples were taken for asbestos during the Inspection. The following persons were contacted: (a)Dave Turner- Safety Director :: (b) Tom Bixler- Union (U.A.W. )Health and Safety Repres entation (c) Dr. John Blackwood, company physician Samples were taken using MSA personal sampling pumps plus AA (0.8 micron) filters, open face.cassettes. The results are ilsted on the accompanying table listing work site concentration (employees exposure) current Thres hold Limit Values (TLV's) from the American Conference of Governmental Industrial Hygienist, 1974 Handbook, and the Federal Register OSHA, 1910.93(a) asbestos regulation. Based on the findings of the survey, the current TLV for asbestos was not exceeded. However,' this Is not to say there Is no problem with handling asbestos throughout. As you know, I had sampled only a small segment of the total operation. And without further samplin&of other operations Involved in the cutting, handling, etc.^qf asbestos, it is hard to determine the extent of the employees exposure to asbestos. Threshold Limit Values (TLV's) refer to airborne concentra tions of substances and.represent conditions under which it is believed thatinearly.all workers may be repeatedly exposed .day'^after,.day.fwithout adverse effects.-- Because of wlde-variations< in^individualy susceptibility,-however .expos- <U>' conditions, or an occupational lllners. Many TLV's are and do not necessarily represent prolonged exposures after many years of working. The following recommendations are offered for consideration. A.I suggest reading the entire asbestos regulation found in the Federal Register 29CFR, 1910.93a Asbestos paying close attention to 1910.93a (c) (1)(1), (c)I ii(a) and (b) and (c) (1) ill, 1910.93a (2)(i) and ii and iii; 1910.93a (d) the entire section, plus methods of measurements, caution signs and labels, housekeeping, record keeping and especially medical examinations. If you should have any questions in regards to these sections, please feel free to contact me. B. I felt that one reason why the last asbestos count was low is because of the practice of wet handling of the asbestos material was used when said material was being stripped from the bin. Whenever possible, the method of working with asbestos wet with approved respirators should be Instituted, however, I should caution you that periodic monitoring should be instituted to determine if the above method is working satisfactorily. When it is not possible to handle asbestos material wet then local exhaust ventilation (See 29CFR 1910. 93a (c) (1) or Type "C" supplied air respirators, continuous flow or pressure demand class. Again, monitoring should be instituted to determine if instituted methods are effective. Concurrent with the inspection, I was informed that at times, welders will enter "confined spaces, boilers, bins, etc., for repairs. I am enclosing a copy of a Confined Space Entry Procedure, and suggest that it is read carefully and approp riate action be taken. 0SHA has regulations in regards to welding in confined spaces 29CFR 1910.1910 252 (f)(4) i,ii, iii, iv, v, I suggest that you review them. Lastly, I would like to direct your attention to the fact that effective July 1, 1976 the 8 hour'time weighted average for asbestos will be 2 fibers per cubic centimeter as required by OSHA. If the Division can be of further assistance to the company, please feel free to contact us. DS:bs Dale Selchan Industrial Hygienist Enclosures Confined Space Entry
