Caution signs should be pooted at all approaches to areas con taining excessive concentrations of airborne asbestos fibers. This is an OSHA requirements as set forth in the Code of Federal Regulations, and is listed heroin as a repeat recommendation dating back to our survey reports of August 14-18, 1972, October 2-6, 1972, and September 10-14, 1973 . 7C-9 Employees are not being notified of their own excessive exposure to airborne asbestos so that they can taka appropriate protective measures whether it be through the consistent use of respirators or core careful work habits. Employees should be notified in writing of their personal exposure as soon as practicable, but not later than 5 days of the finding. They shotild also be advised of the corrective action being taken. This is an OSEA requirement as s-et forth in the Code of Federal Regulations, and is listed herein as a repeat recommen dation dating back to our survey reports of August 14--18, 1972, October 2-6, 1972, and/ September 10-14, 1973. DISCUSSION During the survey, two or more short term samples were collectec at each of several operators, particularly in Book and Blok Preform, to obtain averages of levels throughout the day. These particular locations are listed below with the actuc 1 and averaged values. LOCATION ACTUAL LEVELS f jbcrs/ml AVERAGE fibers/ml Book Preform #19 Book Preform it2 Book Preform *4 Blok Preform 4-5 Blok Preform Blok Preform -77 . 3.78 and 4.26 4.41 and 6.G5 3.56 and 6.55 3.74 , 3.01, and 7.10, 4.41, and 5.42 and 6.75 5.19 5.33 4.02 5.63 5.05 5.65 5.61 6.1 It would have been ideal rf 5 separate samples could have bean taken at each location for purposes of closer averaging and to comply with OSHA sampling requirenents . However, in this instance, time vos United since Done asbestos counting was dona on site la addition to sample collection. The above data do show fluctuations, but none arc cortrcnc, and it i3 apparent that the averages are reasonably representative of actual 8 bom time weighted exposure levels. The short tern method of samp ling Is necessary when airborne particulate concentrations are elevated. Prolonged sampling at some locations overloads the filter, preventing accurate identification and sizing of fibers during microscopic examination, then this happens, erroneous fiber levels of from 10 to 100 times below actual concentrations may be reported. As indicated in Appendix No. 1, booh and blok preform samples continued to show elevated fiber levels, especially when re lated to the 2 fiber limit scheduled for adoption by OSHA in. July. Since ventilation changes have not resulted in notice able reduction from levels of December 16-20, 1574, it is apparent that sources or points of najor dust release at each blob and book, preform unit have not been adequately ventilated. Host past survey reports have stressed the need for proper exhaust enclosure of the mix buggies and hand transfer portions of the processes. This need is again reiterated. Xt is our understanding that engineering controls are to be installed at the mix buggy locations in Blok Preform in the near future. These plans should also include Book Preform where hooding installations have helped to reduce scattering and spillage, but have had moderate effect cn airborne fiber concentrations. A recent Industrial Hygiene Eurvey at Salisbury-FPG bas dis closed preform fiber levels ranging from 0.5 to 1-5 fibers/d. One or two locations were above 2 ffbors/nl, but the reasons for tha excursions were easily pinpointed and were attributable solely to poor work practices. The mix buggies and weigh scales are provided with exhaust ventilation at the Salisbury plant which appears to be containing effectively airborne asbestos levels, at least to the 2 fiber level. It Ih sugccstcc that FPG-hTincbester inspect tbs nix buggy enclosures at Salisbury and consider adopting some cr all of their principles of asbestos containment. There appears to be no clear pattern of aebsstos exposure os it relates to the type of nix being used at the individual work station. Careless work hobrts and/or excessive scatter ing of the nix can be assured to be a factor, but there are no pronounced variations except for airborne lead levels withru the eurvey data to cupport this contention. The operator at blok preform No. 5 was selected for sampling because c the presence of csbcstoa mix on floors, equipment, end clothing, end excessive dust generation during ccooping and weighing. The lovols during three different sampling periods were 8.74 fibers/ml, 3.01 fLbers/ml, and 5.19 fiber c/ml. These voluoa do not vary significantly from those encountered at core fastidious blok preform operations. This lack of effect of parsonal variables tends to further indicate that tbe source of excessive asbestos exposure is common in origin. Remain ing, heavy sources of exposure at t-oth book and blok preform are the mix buggies and the manual operations associated there with. ' In relation to the airborne lead results in Appendix No. 2, excursions above the 0.15 r*gAi3 Threshold Limit Value uera confined to two locations in Blok Preform. One of the loca tions was blok preform No. 5 (cample No. 25) which, sa pre viously stated, was selected for sampling because of excessive duct generation and poor housekeeping conditions. This opera tor also worked at Elok Preform No. 3 during the morning hours (sarcoLc No. 10) where airborne lead levels were high (.135 mg/l^) but not above the Threshold Limit Value. It would be aaviscable to provide this operator with instructions as to proper work habits and the need for consistent good housekeeping. Throughout tha plant, it was observed that only a few people were waaxing respirators. in known exposure areas, only one man was so equipped. This operator's respirator was not worn continuously during dusty operations, but was only worn when the operator himself felt that protection was warranted. I inspected the respirator after the operator had deposited it on a dusty ledge, and found it to be dirty, and smudged both Inside and out, and tha filter was thoroughly caked with asbestos fibers and particulates. It is imperative that a respiratory protection program be established in the plant v'vereby all exposed employees are provided with and required to wear approved, properly main tained respiretory protection. This recommendation has been sot forth in several previous reports. Although respirators are provided on a voluntary basis within the plant, this is not sufficient since virtually ail of the exposed employees remain unprotected. To have any positive or lasting effeens the program must be implemented cn a mandatory basin. In addition, the employees should ko thoroughly instructed in the use of the equipment, end a central maintenance; program should bo established. Maintenance is on important phneo of c.ny control procedure, and 1b aa true for respirator: os it is for ventilation equip-- rivent. No matter her; woll a rorpirator is designed, hew good it3 perforcanco, it cannot give satisfactory protection unless it i3 maintained in good condition. This la one of the moat frequently neglected factors, particularly with routinely used respirators. The operations of a maintenance program, including frequent inspections, cleaning, replacing, or re pairing worn or deteriorated parts, and storage, should be centralized. They should also be supervised carefully by a responsible and capable person since proper care and niaintensnce requires a thorough knowledge of the devices. All routinely used respirators should be inspected frequently. Tha tightness of connections 3hould be checked, as well as the condition of the facepiece. exhalation and inhalation valves, connecting tubes and/or cartridges, and cannisters. Respirators should be cleaned after each use, and they should be collected at a central point at the end of each shift for cleaning and inspection. Each employee's respirator should bear some sort of identification, such as his initials or clock number. When a worker receives a respirator, he should be briefed on the cleaning procedure and assured that he will always get the same device. If the respirators are serviced between shifts, only one respirator per worker is needed. If the cleaning is done during a shift, each worker will require two respirators. Tfhen not in use, the respirators should be stored in clean cabinets at convenient locations in the work area. As long as each respirator is assigned to only one person, there is no reason to require special sterilizing. Scrubbing with warm water and soap, rinsing, and air drying is adequate. When tha respirator is used by only one indivi dual, a practical method of cleaning is as follows* 1. Remove the filter or cartridge and discard. o 2. Wash m detergent or soap in warm water. 3. Rin3Q completely in clean, warm water. 4. ,? ir drv the device m e clean area. 5. Inspect the valves, beadstraps, end other pareaf replace with nr; parts if defective. 6. Insert new filters or cartridges; make Gure tho coal Is tight. 7. Place in a plastic bag for storaga. After cleaning, inspection, and necessary repair, the respira tors should be stored ir. dust proof containers, away from sun light, heat, extreme cold, and excessive moisture. Plastic bags are adequate for routinely used respirators. They chould not be stored in clothes lockers or tool boxes, care should be talcen to see that they arc packed or stored so that the rubber facepiece and exhalation, valve will rest in a normal position end function will not be impaired by the rubber set ring in a bent or twisted position. CCKCLU5IOMS Housekeeping had been improved at several locations through out the plant, particularly in Lower and Upper Compounding. Further improvement is needed in Elok and Book Freform. Significant asbestos exposures are limited to two departments where design and installation of exhaust equipment are under way. Efforts choulc bs concentrated or. ventilating mix buggies and ancillary manual operations In both Ecok and Elck Preform. Interim protection in the form of respirators should be provided for the operators. Use of the devices should be a condition of employment in these two areas. Isolated asbestos exposures at Disc Brake Inspection and the dry line operation in Lower Compounding require engineering control. Interim protection in the form of respirators should be provided for the operators.
