Sampling guide for air contaminants (8th Edition)
| |
Cited as a reference document in the Regulation respecting occupational health
and safety (RROHS), this guide describes the strategy and methods for
measuring workers' exposure to gases, fumes, vapours or dusts so that means of
control can be implemented. The modifications and additions to this eighth
edition take into account the recent evolution in workplaces and the Québec
health and safety regulations. The Sampling Strategy chapter has been enhanced
by the addition of new references and reorganized to make its content comply
with the RROHS. In the Instruments and Sampling Techniques chapter, a new
section called Compliance with the RROHS's permissible exposure values (PEVs)
clearly states the invariable nature of PEVs in relation to temperature and
pressure. This change led to substantial modifications to the chapters on pumps,
flowmeters and calibration. The sections on direct-reading instruments, analysis
of respirable compressed air, microbiology and surface tests were also updated.
