The
Western workplace labelling system involves the use of
a commercially available label which is coded according
to the Hazardous Materials Identification System. The
codes are interpreted by referring to the Workplace
Labels for Hazardous Materials Protection Index. (see
diagram below) A wall chart of the Protection Index
is available from OH&S.
Labels are available from commercial suppliers such
as VWR, Fisher, etc., Occupational Health and Safety
(OHS) has samples. The information
required to determine a rating for health, flammability
and reactivity as well as the personal protection is in
the MSDS for the chemical. Personnel in OHS can be consulted
to assist with the determination of a rating from the MSDS information.
The best information can be obtained from the MSDS on the manufacturer’s
website. The following websites are excellent alternative
sources for MSDS information. CCOHS
