t*// Ct'/y /t,
(1) Permissible concentrations of asbestos fibers
(2) Methods of compliance
(3) Warning signs & labelling
(1) Monitoring
(5) Medical examinations
(6) Record keeping
1 - Permissible concentrations of asbestos dust
jThe limit of occupational exposure to eight hours of asbestos dust

ten fibers are permitted up to fifteen minutes/hr.)

To determine what the asbestos dust exposure is in pipe coverer's
work areas, a 9L4g work order is being processed to purchase a
Bendlx Cl 15 Personnel Monitor. This sampler is recommended by
Frank Fuller, ESD, and is available thru the Polymer Intermediates
Dept, of the Company at a 10% price discount. Delivery Is estimated
at three weeks.
2 - Methods of compliance Reducing the creation and dispersion of asbestos dust Is the best method of compliance. To achieve this reduction the following Items
are proposed:
A f Wearing of respirators by all maintenance personnel when working with (or In the immediate area of)
