Acknowledgement
The writer visited the plant on April* 8'1982* and-met with Mr. John Pacheco, Safety Coordinator and Hr. Clovis Gauthier, Co-Director of Energy Conservation and Security.
...Purpose
Honor a management request to evaluate* the-hazard potential to talc dust at the packing station for the mill conveyor in Department 11.
Limitation
Neither the visit of our -representative under the* terms of our policy nor the making of this report constitute an undertaking* to determine or warrant that your premises or operations are safe.

Conclusion
' __
Talc dust appeared to be controlled at. the subject work station under conditions extant at time of visit.
. .. ... Description of Operation Relating to Talc Dust Exposure
Strip rubber from the rubber' mill passes- through^a^trough of talc and water mixture then by conveyor to air dry before being hand^packed in transport con tainer for further processing. Some of the talc adhering to the rubber is dislodged during' the packing operation and becomes airborne. Respiratory pro tection is worn during packing.

Method of Sampling and Analysis
A personal sample was obtained in the breathing zone of the packer using an MSA Gravimetric pump and millipore filter. The sample was analyzed for talc concentration by light field microscopy in American Mutual's Industrial Hygiene Laboratory which is accredited-by. the American Industrial Hygiene Association.
The Threshold Limit Value for non-asbestiform talc is 20 million particles per cubic foot of air. See attached Air Analysis Table for laboratory findings.
Comment
Management is currently anticipating the installation of a drying tunnel for the rubber strip material andean -automatic reel revind at the packing ^station. 'This will not-only-further-reduce :talc dust build-up in the area but greatly reduce any worker exposures.
