Exposure Standard Documentation - Safe Work Australia
To minimise sensory irritation to most workers, the Exposure Standards Working Group recommends for xylene (o-, m-, p-isomers) a time-weighted average exposure standard of 80ppm and a STEL of 150ppm . These levels should also be low enough to protect the workers from narcotic and other chronic health effects. REFERENCES 1.
