Rajhans of Messrs H.M. Nelson and - Bendix Automotive of Canada Ltd. January 9 1979 , Comments to 1 According the Company the brakelinings contain between 50 to 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 e Location or Operation Type of Hood Face Opening Face ~Velocity FPM min Air Volume ; f CFM fmin Air Volum CFM in 1976 Grinder 1 Grinder 2 Grinder # Grinder 4 3/4 enclosed 3/4 enclosed 3/4 enclosed 3/4 enclosed 22 x 6 22 x 6 22 .6 22 x " 1200 1200 950 950 1100 1100 870 870 1100 1100 855 855 No fhaust 2 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 linings significant amount of dust is released Some fibers were also observed on the machines as rafter dust Although significant exposure is 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 - ' ~": 4. After the linings are drilled they are dropped on a grated table approximately 23 x 21 x 27 high remove the loose dust which is collected in a polyethylene bag tied under the grated exhausted surface This table is not 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 m ee n 72-71111 mortable vacuum cleaner No dry sweeping - Bendix Automotive of Canada Ltd. January 9 1979 6 One of the employees working on the rivetting machine was seen wearing an approved respirator 3M Co. Type 8710 7. 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 In my opinion the fibre concentration near the fountain is not likely to be significant as judged from the ventilation system and the results of previous surveys carried out near the dust producing operations In order to assess the exact level of asbestos hazard at this location air sampling will be carried out Further Action by O.H.B. will Personal and Area sampling for Asbestos near the following location be carried out 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 dissipate asbestos fibres are allowed to get airborne and 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 2 Further comments will be made after the air sampling results are known a > Amateur O.P.

P .a - Bendix Automotive of Canada Ltd. January 11 1979 General Bendix Automotive of Canada Ltd. has two plants in Windsor the Argyle Avenue plant and the Prince Road plant At the Argyle plant brake linings are drilled riveted to brake shoes and turned on grinding wheels to produce tapered ends The finished product stacked in incline chutes is shipped to the Prince Road plant where complete brakes are assembled At the Prince Road plant the maximum handling of asbestos brake lining is restricted to three categories of employees the employee transferring brake shoes from the chute to the conveyor the pin liner operator and the end of line inspector A total of 300 employees work at this plant but only about 100 of them handle asbestos brake shoes Comments 1. A small amount of dust containing asbestos accumulates at the bottom of each chute This means that the operator transferring brakes from the chute could be exposed to some asbestos fibres To measure the airborne concentration of asbestos area and personal sampling will be carried out by this branch 2 A small amount of what appeared to be very tihe dust containing some asbestos was observed on the work benches At these locations the exposure is expected to be low but will be quantified by air sampling to be carried out by this branch 3 The chutes benches and floor in this area are supposed to be vacuum cleaned but at the time of the visit the vacuum cleaner was out of order and the dust was being swept dry ' Recommendations . Although the airborne concentration of asbestos is not expected to exceed the Ontario interim standard of 2 fibres the best practice =: is to keep this concentration as low possible Vacuum cleaning is bence recommended and the dry sweeping should be discontinued Bendix Automotive of Canada Ltd.
