NEW FEDERAL ASBESTOS STANDARD PROMULGATED
'OSfTA has dI cover! that c u rre n tly e ffe c tiv e 'sta n d a rd s for" ASBESTOS DUST cunceivtratlonfi are dangerous to on employee's health and ha Instituted a new emergency standard to reduce the ALLOWABLE CONCENTRATIONS OF THIS HAZARDOUS SUBSTANCE.
The o ld standard vas up to iz f ib e r s duet per m ill l i t t e r of atmosphere ( I t the fibers,are* groater thBn 5 microns In length') f o r an elpht-heur time-weighted average.
.Thd haw emBrgencv standard Immedletely' e ffe c tiv e has reduced
the parmtcslblo as not to exceed {? fib e rs par m illilit e r for
the same sized p a rticle s. Employers most provide engineering
controls to abate excessive dvst concentrations and provide
respiratory equipment share t he controls are not feasible or
capable o f controlling th& dqsf le v e l* . Requirements, have
also been established for the asp o f dvst col reefing devices
bend type end paver tools end for gathering-end disposing
of asbestos dust.
