Detenbeck Abstract An engineering visit was made to assess the asbestos exposure to approximately_ 10 to 12 employees involved in drilling rivetting and grinding of asbestos containing brake linings at the above mentioned plant The grinding wheels and drilling machines are adequately exhausted but some concern of exposure is expressed at the rivetting operation where no mechanical local exhaust is provided | Air sampling will be carried out by this branch to measure the airborne concentration of asbestos Recommendations are made to confine and capture airborne asbestos at dust the grated table where drilled brakelinings are dropped to shakeout loose ot in the drilled holes No directions are suggested to be issued REREEKRURRRAIREERRERRERREARRERRERERE In the above mentioned plant brakelinings are received in a shaped form are drilled and rivetted to brake shoes They are finally tappered by turning on the face of grinding wheels A detailed description of the process is described G.S. Rajhans in previous field visit reports of Messrs H.M. Nelson and 2 Bendix Automotive of Canada January 9 1979 Ltd. Comments to 1 According the Company the brakelinings contain between 50 60 chrysotile asbestos The asbestos content of a particular batch depends upon the supplier of the linings Local mechanical exhaust is provided at the two most dust producing operations drilling two machines and grinding four grinding wheels . Air velocity measurements were made using a velometer and are listed in the table below .

At the rivetting machines no local mechanical exhaust is provided Concern was expressed that some loose dust in the drilled holes gets airborne during rivetting The amount of dust in these holes appeared quite small but the workers informed me that with certain types of brake liningsa significant amount of dust is released Some fibers were also observed on the machines as rafter dust Although significant exposure is not expected air sampling at or near the rivetting operation will be carried out by this branch 3. The drilling operation is enclosed and it was not possible to measure the exhaust rate However the mechanical exhaust appeared to be quite effective oo 4. After the linings are drilled they are dropped a grated table approximately 23 x 21 x 27 high to remove the loose dust which is collected in a polyethylene bag tied under the grated surface This table is not exhausted and some of the loose dust gets airborne as drilled linings are dropped The concentration of airborne asbestos did not appear to be excessive as most particles - . were quite coarse However air sampling in the vicinity will be ; carried out to evaluate the airborne concentration of asbestos 5 Floors and machines are vacuum cleaned using a NILFISK pump type GA 73-7111 portable vacuum cleaner No dry sweeping is permii n tt he t asbe estd os handling area wt +4 ve er Bendix Automotive of Canada Ltd.

Concern was expressed that the water fountain is located one corner of the room where asbestos is being handled and it be a potential source of hazard for all workers in the plant in may not and In my opinion the fibre concentration near likely to be significant as judged from the the results of previous surveys carried out the fountain is ventilation system near the dust producing operations In order to assess the exact level of asbestos hazard at this location air sampling will be carried out , eee , ~ Further Action by O.H.B. Personal and Area sampling for Asbestos will be carried out . near the following location i Rivetting machines Drilling machines Grinding machines Near the water fountain Recommendations When dealing with hazardous substances such as asbestos the best practice is to keep their airborne concentration as low and as confined as possible At the grated table see comment 4 asbestos fibres are allowed to get airborne and dissipate in the room In order to confine and capture these fibres it is recommended that the grated table should be enclosed e.g. a hood with one side open and adequately exhausted ( 150-200 CFM per sq foot of the face of hood _ comments sampling 2 Further are known will be made after the air results mahir > O.P.
