Steffey - Ponca City, Oklahoma November 4, 1976 PROCEDURES TO BE USED FOR MONITORING BY THE OCCUPATIONAL SAFETY AND HEALTH ADMINISTRATION Attached to this communication is a general policy for procedures which will be followed by OSHA for monitoring for substances in the workplace. Attention should seriously be given to this since your area of operations will be subject to such scrutiny, and hopefully we will know and should be aware of the status of the conditions as related to materials present, used or manufactured in the workplace. We would invite your comments, questions, or discussions concerning these important coming requirements which will potentially effect every work place. This communication is supplemental to previous information which has for the past year been issued by the medical department concerning requirements of the joint QSHA-NIOSK Standards Completion Project.

Steffey Industrial Hygienist rla Att. vvc OOQOlQi NEW HEALTH STANDARDS - PROCEDURES FOR MONITORING A list of standards to be issued within the next three months and new procedures for monitoring by Occupational Safety and Health Administration industrial hygiene officers have been announced. The coke oven emissions standard should be issued soon and others shortly following will include noise, rules on cotton dust, lead, mercury, silica, ketones, sulfur dioxide, and ammonia. Each standard will include new rules on recordkeeping procedures and on physical examinations for employees. On the new monitoring procedures the OSHA Field Operations Manual will be revised. The provisions will provide general policies on inspections of plant operations for potential health hazards in the workplace. The national office will coordinate this program among the OSHA regions and an industrial hygienist will be appointed for each region. Consul tation and technical assistance will be made available to these regional hygienists. An OSHA program for training industrial hygienists will include the education of some 400 personnel over the next three or four years. This will involve a thrce-vear training program and the trainees will accompany senior hygienists on some inspections during that period. Responsibilities of the senior industrial hygienist will include providing guidelines for determining non-compliance, contested case information preparation, and training for use of equipment. The industrial hygienist, in making inspections, will be checking for such potential hazards as eye irritations, visible clouds from ventilation systems, visible fumes released in the workplace, a noise level which causes raised voices, chemical handling techniques, and workers' comments or symptoms. If an industrial hygienist finds a potential hazard, he must report the name of the plant, the location of the hazard, the reasons for suspecting the hazard, comment by employer and employees, and samples. Details of industrial hygiene inspections will include checking the requirements for recordkeeping, engineering controls, work practice controls, protective devices, and housekeeping practices. yVC 0000101 Dow tests show HCBD is carcinogenic, but there may be threshold limits Tests at Dow's toxicology labs indicate there is a threshold limit for carcino genic effects of hexachlorobutadiene (HCBD). Dosages of 20 mg./kg. of ani mal body weight per day caused multiple toxicologic effects, including kid ney cancer, in rats tested. But dosages of 2 mg./kg. caused damage that was considered reversible, and dosages of 0.2 mg./kg. caused no adverse effects. Dow reports. Other tests showed no effects on reproduction. HCBD is a ma jor component of the tarry wastes from the manufacture of trichloroethy lene. perchloroethylene and carbon tetrachloride. Reviews of health data on workers in areas where HCBD has been found indicate no abnormalities or deaths that could be attributed to the chemical. The company says concen trations of HCBD in its commercial products is well below 1 ppm. Bayer waste treatment method makes better use of oxygen in air Bayer has developed a new method of treating waste water. Air is injected through spray nozzles into towers up to 60 ft. high. Purpose: to get better uti lization of the oxygen, which sustains life of the bacteria that consume the organic wastes. Bayer researchers say that of the 21% oxygen in air. only 5r7 is actually utilized in conventional waste-water treatment in which aeration takes place in relatively shallow lagoons or holding basins. The company says its method, which it calls tower biology, uses 13% of the oxygen in the air. Result: less air has to be blown in. so energy costs can be cut as much as 50%. Bayer also claims space requirements and capital cost savings. The company plans to build a tower biology unit at the treatment plant adjoining its giant Leverkusen works. ERDA and USDA to test use of power plant wastes for agricultural purposes Can power plant wastes be used as fertilizer? The Energy Research and De velopment Administration and the Agriculture Dept, are cooperating in a SI.7-million, five-year study of the use of solid wastes from coal-fired boilers that burn coal mixed with limestone in a fluidized bed for fertilizers and soil treatment. The project will include chemical and physical analysis of the combustion wastes, followed by studies of the materials in greenhouses, growth chambers and fields. Field studies will evaluate use of curving amounts of the waste on marginal soils and land areas. The wastes will also be tested for possible role in neutralizing acidity in strip-mined land. Reflux refining will be tested to make lead A new lead refining process will be tested in a I-metric-ton/hour pi lot plant being built by Broken Hill Associated Smelters at Port Pirie. Australia. The process, called "reflux refining," was developed by the government-run Commonwealth Scientific and Industrial Research Organization (CSIRO). The Australians think it shows promise of making a lead product with fewer impurities than current commercial processing. Moreover, it uses less energy and can recover valuable by-products. CSIRO's experiments have shown that lead ingots containing 1.700 ppm. of silver can be processed to contain only 0.5 ppm. of silver. At the same time, the other main impurity, bismuth, can be reduced from 320 ppm. to 80 ppm. In comparison, the existing pro cess at Port Pirie leaves 1.8 ppm. of silver in the lead without reducing the bismuth concentration. 64 CHEMICAL WEEK September 8. 1976 vve 000010108 2 orpiQ* lrv-6^-------- b j e^oT // ' i ~$/J -- /^: , (/ t 'rt<zA~t>r^ - ticA^r^ ** j /'fQfrMQjy ^7. ^ i ~jo i- K / * ^9/ / r* i-- TiJK V, \U.

The> document recommending a revision of the1 standard noted that "available informationi indicates that large doses of eplchlorohydr.nl induce antUertility effects or rats; however,; no effects on potency have been found." | Research on Mice | __ The research of Dr. Benjamin L. Van Du-| uren. professor of environmental medicine; at New York University Medical Center. - . was submitted to the institute's review com mittee. Dr. Van Duuren injected epichioroh- ydrin under the skin of 30 mice, and as a re* --- -- suit, two developed malignant tumors. 1 **Thee results create concern," he said. Dr. j Van Duuren said his research on epichioroh- j * .............. ydrin was an outgrowth of his work on 313 j Cchloromethyli ether in the l&60s. ! Inhalation tests were begun last year alt ...... ` the medical center under contract from the* National Cancer Institute. Sidney Laakin. afr V.__. . pharmacologist and director of the study, f said it will be a year or two before test re- suits are available. "But preliminary tests ----------------- have shown that epichlorohydrin is a muta gen and carcinogen," he said. The institute reviewed the environmental ------------------limits on epichlorohydrin as part of its mis sion under the Occupational Safety and Health Act, which calls for it to set exposure stan. dards fQr ^ ufetimeof workers. The institute J has turned over its recommended standard! on epichlorohvdnn to the Occupational Safety > " and Health Administration. { *\Vc don't have a complete set of epide-j ..... ....... --.. . miologlcal data," said Jerome Chandler, a; biochemist at the institute. "Every occupa-j tional standard is a theoretical extrapolation! -- from a more limited set of data. But we dot know epichlorohydrin induces mutation and! reacts with DNA in lower organisms. We. ............ ;------- recognize these bits of data as tips of thei iceberg of an unknown size." * I - <. VVC 0000X0110 4 /fodJ9'T&ek.
