Atmospheric samples were collected to determine the airborne concentration of asbestos fib^r present in various warehouse locations. The results of these tesLc in conjunction with procedural observations, were used as criteria to establish guidelines and prescribe recommendations to help insure a health- ful work environment. ^|OTP* '' ! OSD METHODOLOGY Personal and/or fixed location samples were collected in several warehouses where asbestos was stored. In order to assess employee exposure to the contaminant during handling operations, two mock operations were conducted. At the Marlon Depot, the potential exposure for the lift-truck operator, checker and inspector were determined for an operation involving the re-location of palletized asbestos packaged in burlap bags. Ac Fort Wayne (Ccsad Depot), samples were taken of a cleaning operation involving the patching of corn burlap bags and Che vacuuming of the bags.

For ell ocher locations at both Depots, area samples were taken during dormant conditions. Only in section 4, Warehouse T-214 (Casad Depot), was'there any activity (lift-truck activity in adjacent section approximately 20-30 feet from asbestos stacks). NO . '". Atmospheric samples for asbestos were collected on 0.8 micrometer tyi) pore si2fe nixed cellulose filters with a diameter of 37 millimeters (am). The filters were incased in a three piece plastic cassette with the face piece removed (open faced) during sampling. Battery powered Mine Safety Appliance (MSA) gravimetric pumps. Type G, equipped with pulsation dampeners were used to draw air through the filters at a rate of 2.0 liters per ninutu (1pm). Personal samples were collected by having the employee wear th.- pump with the attached filter positioned within his breathing zone. Area samples, placed in proximity of the asbestos stacks.,, were- '^.\X) taken using the same equipment. - The samples were analyzed at the Salt Lake City Laboratory. The procedure consisted of counting fibers greater than 5 jx in length at I 400-450 magnification, using phase contrast Illumination, with the sample * negated in a high-viscosity solution of membrane filter material.

Their chief characteristic is a structure composed of long, parallel, flexible fibers, capable of re- * petted longitudinal subdivision. The nost widely used form in the United States is chysotilu, a fibrous form of serpentine. Ocher types Include amoslte, crpcidolite, tremolite, anthophyilite and actinolite. Prolonged inhalation of asbestos fibers may result in a fora of pneumoconiosis known as asbescosis. The fibers, upon deposition in the terminal bronchioles, initiate: a tissue response which results in the coatiug of' the fiber with the ultimate production of what is known as the asbestos "body". If large quantities of the fibers arc inhaled over a prolonged period, the tissue reaction progresses until a gen eralized, diffuse fibrosis becomes evident. This fibrosis is first seen in the lower lobes of the lungs but eventually, if exposure continues, appears In the other lubes as well. Respiratory insufficiency end cardiac failure may supervene due to the impaired oxygen transfer across th--: alveolar membranes.

Along with ar.bcstrjsis, recent studies have indicated a relationship between inhalation of asbestos and cancers of the bronchi, pleura and peritoneum.- However, data is not conclusive to define the association of each type of asbestos to the formation of the mesothelioma. FEDERAL STANDARD The existing standard for asbestos (29 CHI 1910.93a) based on an eighthour time-weighted average (TWA)* shall not exceed 5 fibers longer than 5 micrometers per cubic centimeter (u/cc) of air, with a coiling value of 10 fibers longer chan 5 u/cc of air. Effective July 1, 1976, the Department of Labor (CSiiA) Standard will be 2 fibers/cc. DISCUSSION CF RESULTS AND RECOMMIEIDATIOXS At the lisrioa Depot the checker's exposure to asbestos was close to but below the proposed standard effective July 1, 1976. Samples collected in warehouses with little or np activity yielded results below the analytical of detection (Tabic 1). weighted average (TWA) exposure during any 8-hour shift of a 40-hour work wve!;.

Vacuuming a.:d repairing of acbcr.toi; filled bags were the most hazardous operations evidenced during the survey, (Table 2). Personal samples taken on two of the three fort*, lift operators during asbestos bag vacuuming and repairing were iu excess of proposed standard. In view of the sampling results, the hazardous properties of asbestos, and the effective date of the new standard, it would be advisable to implement the U.S. Department of labor's proposed standard at this time. Basic guidelines sited herein are from the Occupational Safety and Health Act of 1970 (29 CFR, 1910.93a Volume 39, June 27, 1S7A) and the `.IIOSII Criteria Document HSl'l 72-10267. Attention should be given to employee education or awareness programs, improved hygiene and work practices, medical examinations and a respirator program as discussed in the following paragraphs. Bach employee exposed to asbestos s0hould be advised of all hazards and precautions concerning use or exposure. Each exposed worker should bo informed of the information applicable to a specific product or material containing 52 or more asbestos. The information should be kopje on flic and readily accessible to the vorUur at all places of employment where asbestos materials are used in unit processes and operations.

V'hcn the limits of exposure to asbestos dust cannot be net by engineering controls or administrative techniques, an employer must utilise a program of fespiratory protection and furnish protective clothing to effect the required protection of every worker exposed. A. Respiratory Protection For the purpose of determining the.class of respirator to be used, * the employer must measure the atmospheric concentrations of airborne asbestos in the workplace initially and thereafter whenever process, work site, climate or control changes occur which are likely to affect the asbestos concentration. The employer shall test for respirator fit and/or make asbestos measurements within the respiratory inlet covering to insure Chat no worker'is being exposed to asbestos in excess of the standard either because of improper respirator selection or fit. 1.

Instructions on the adjustment of the equipment and methods of replacement of parts are necessary for the user. 3. Respirators shall be inspected periodically and cleaned after each use. Face pieces shall be cleaned in warm soapy water and disinfected with hypochlorite solution. Replacement of filters may be necessary following excessive breathing resistance, or when worn or deteriorated parts are noticed. * A. Respirators shall be stored in dust proof containers or their own cartons. Rubber parts should not be stored in a crushed position as distortion of the face piece may occur. Equipment for emergency work shall be stored in locations easily accessible. 5.

KFOTCAL SURVEILLANCE NOTE: NOT CC ,, Medical surveillance is required for all workers who are exposed to asbestos as part' of their work environment. The major objective of such surveillance will be to ensure proper medical management of individuals who show evidence of reaction to past.dust exposures, either due to <p:ccslve exposures or unusual susceptibility. Medical management may range from recommendations ns to job placement, improved work practices, cessation, of smoking, to specific therapy for asbestos-related diseased or its triplicationTM.

Do not hand stack asbestos in railroad shipping cars unless each bag is sealed.in a plasrie wrapping. Uand stocking of burlap bagged asbestos in the confined space of a railroad car con cause excessive concentrations of asbestus dust. 13. Engineering controls should be installed to reduce asbestos exposure to within safe limits. If engineering controls are not feasible. administrative control and/or personal protection is required.
