Abstract:
An air quality assessment visit was made to th above company and the attached tables summarize,the results of this visit.
Air samples for 1,1,1 Trichloroethane were taken by drawing air
I
through glass tubes containing charcoal, at an air flow rate of 100
millilitres per minute, using portable low^flow air sampling pumps.
Samples were taken sequentially.
Air samples for Zinc dimethyl dithlo carbamate were collected on tared 0.8 micron pore-size cellulose ester filters, using portable air sampling pumps, at an air flow rate of two litres per minute. The results of these samples are reported as total dust and zinc content (The laboratory was unabla to report total zinc dimethyl dithlo carbamate).

Degreasing of small parts, using 1,1,1, Trlchloroethane, by the stock man is performed only once or twice dally, at which time enough parts are prepared for the whole day's production. On the day of the visit, enough parts had been prepared for each line prior to our arrival. A simulation of this operation on line #2 was arranged to enable air samples to be taken. (Sample #104).
Air sampling for zinc dimethyl dithlo carbamate was done on two lines, #3 and #6, that were using diaphragms coated with the zinc diemthy1 dithlo carbamate, which has the appearance of a bluish bloom. (More recent purchases of diaphragms are from a new .supplier and no longer are coated in zinc dimethyl dithlo carbamate)* The union, however, were more concerned with a third type of diaphragm, on which the zinc dimethyl dithlo carbamate appears as a shiny needlelike crystalline deposit. These particular diaphragms were not in use at the time of our visit, therefore the assembly operation using these diaphragms was simulated by the operator removing diaphragms from the shipping case, placing them on the assembly block and returning them to another case (Sample #12). The two simulations described above were arranged between the area supervisors and the union safety representative*

C a r m ents:
.
1.
On May 2 air sairpling was done at this plant for : trichloroethane anl
total dust.
2.
The airborne concentrations of trichloroethane were within the
levels acceptable for occupational exposure in Ontario.
3.
From the total dust measurements it nay be concluded that, a person
could be exposed to an airborne concentration of 1.26mg/nr of
zinc dimethyl dithio carbamate at most. As stated in the discussions
with both Company and Union since a TLV does not exist for zinc
dimethyl dithio carbamate there is no standard with which to conpare
this exposure. However, it should be stressed that iru^cus membrane
and skin irritation nay occur with this substance.
4.
It is felt that the working environment is within acceptable
standards at this plant with regard to trichloroethane. For those
workers that are irritated by the zinc dimethyl dithio carbanate
protective equipment should be provided as outlined In the original
report.

SUPPLDiENTARY TO PREVIOUS REPORTS:
The attached Air Quality Report Ho. 1397 shove .that none of the sixteen samples taken from the above mentioned plant indicated asbestos concen tration in excess of the proposed Ontario Standard of 2 flbres/cc.
Comments:
1. One sample (08) representing the exposure to the vacuumer shove a concentration of 1.7 fibres/cc. Although this value is below the Ontario Standard of 2 fibres/cc, it should be realized that the standard is based on a time weighted average for 8 hours. The Job of vacuuaer is such that the asbestos exposure could vary significantly in space and time. In my judgement, the vacuuaer may sometimes be subjected to concentrations in excess of the standard in spite of the lower measurements
2. Asbestos concentration in one sample (#7) representing personal exposure of a hand liner assembler is found to be 1.8 flbres/cc. * This value is In contrast to 0.75 fibres/cc measured in another . sample (#6) from similar operation. The difference between the two may be due to variability in dust generation with different work practices, or different types of brake shoes.
- 2-
Hay 24, 1979
Although none of the samples show concentrations in excess of the Ontario Standard, the best practice is to keep the asbestos levels to as far below the Standard (2f/cc) as possible. ,
1. Adequate dust control measures should be provided at the hand linec '
assembly stations to ensure that the personal exposure to workers
does not exceed the standard of 2 f/cc. Until such measures are
,
provided, it is recommended that the hand liner assemblers should
wear approved respirators that provide protection against pneumoconiosis
causing dust.
,
2. Approved respirators that provide protection against pneumoconiosis
causing dust should be worn by the vacuumer.
Note :
In Ontario, the approval list of National Institute of Occupational Safety and Health Is normally accepted.

SUPPLEMENTARY TO PREVIOUS REPORTS:
The attached Air Quality Report No. 1398 shows that airborne asbestos c centration is below the Ontario Standard of 2 fibrcs/cc, in all the sac es.
During my last engineering visit, (O.H.3. #05773 KEOA), concern was exp that the water fountain is located in the same room where asbestos is h and employees from other areas of the plant have to come to this room t use the fountain, thus causing unneccesaary exposure. One sample taken near this water fountain (#14) shows fibre concentration of 0.44 fibres This concentration is not excessive and probably represents the backgro In my judgement, the exposure at the water fountain is minimal.
ssed died,
t. d.
However in view of the fact that asbestos is considered to be a carcino n, it is suggested that unnecessary exposure to asbestos be avoided.by relocating the drinking fountain elsewhere in the plant with no asbestc exposure.

SUPPLEMENTARY TO PREVIOUS REPORTS:
The attached Air Quality Report No. 1397 shows.that none of the sixteen samples taken from the above mentioned plant Indicated asbestos concen tration In excess of the proposed Ontario Standard of 2 flbres/cc.
-C-o-m-m-e-n-t-s-:--

.
>
.
1. One sample (#8) representing the exposure to the vacuumer shows a concentration of 1.7 flbres/cc. Although this value is below the Ontario Standard of 2 flbres/cc, it should be realized that the standard is based on a time weighted average for 8 hours. The job of vacuumer is such that the asbestos exposure could vary significantly in space and time. In my judgement, the vacuumer may sometimes be subjected to concentrations In excess of the . standard in spite of the lower measurement.-
2. Asbestos concentration in one sample (#7) representing personal exposure of a hand liner assembler Is found to be 1.8 flbres/cc. ' This value is in contrast to 0.75 flbres/cc measured In another .. sample (#6) from similar operation, the difference between the two may be due to variability in dust generation with different work practices, or different types of brake shoes. .

Recommendations:
Although none of the samples show concentrations In excess of the Ontario
I
Standard, the best practice Is to keep the asbestos levels to as far below
the Standard (2f/cc) as possible. ,
1. Adequate dust control measures should be provided at the hand liner
assembly stations to ensure that the personal exposure to workers
does not exceed the standard of 2 f/cc. Until such measures are
,
provided, It Is recommended that the hand liner assemblers should
wear approved respirators that provide protection against pneumoconiosis
causing dust.
2. Approved respirators that provide protection against pneumoconiosis
causing dust should be worn by the vacuumer.

In Ontario, the approval list of National Institute of Occupational Safety

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 sanpling will be carried out by this branch to measure the airborne concentration of asbestos.
Recommendations are made to confine and capture airborne asbestos at the grated table where drilled brakelinings are dropped to shakeout loose dust in the drilled holes. No directions are suggested to be issued.
***********************************
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 in previous field visit reports of Messrs. H.M. Nelson and G.S. Rajbans.

Bendix Automotive of Canada Ltd. January 9, 1979_________________ Coimtents:
i . According to 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 (tv 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 linings a 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.
4.
After the linings are drilled, they are dropped on 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.

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 in one corner of the room where asbestos is being handled and it may be a potential source of hazard for all workers in the plant.
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.
Personal and Area sanpling for Asbestos will be carried out
near the following location:

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).
2. Further comments will be made after the air sampling results
are known.

Brake shoes containing asbestos brake linings are used to assemble complete braking system for automobiles at the above referred plant. A small amount of asbestos fibres become loose during handling of the brake shoes. It is likely that some of these fibres could become airborne and be a source of potential hazard. However, personal and area sanpling for asbestos will be carried ou t by this Branch to measure the airborne concentration.
The hazard is assessed to be minimal and no directions are suggested to be issued at the present time. Reccrrmendation is made to practise vacuum cleaning instead of dry sweeping.

Bendix Automotive of Canada Ltd January 11 1979
General:
Bendix Automata.ve 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 couplete ' brakes are assembled. At the Prince Road plant, the maximum handling of asbestos brake lining is restricted to three categories of enployees: 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 o f what appeared to be very fil^e 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/cc, the best practice is to keep this concentration as low-as possible. Vacuum cleaning is bence recommended and the dry sweeping should be discontinued.
