As has been mentioned the GHS/HCS 2012 classification leads to
specified precautionary statements. However, there are options/choices within
some precautionary statements. C.2.4 Precautionary
statement text C.2.4.1 There are four
types of precautionary statements presented, "prevention," "response,"
"storage," and "disposal." The core part of the precautionary statement is
presented in bold print. This is the text, except as otherwise specified, that
shall appear on the label. Where additional information is required, it is
indicated in plain text. C.2.4.2 When a backslash or diagonal mark ( / ) appears in the precautionary statement text, it indicates
that a choice has to be made between the separated phrases. In such cases, the
chemical manufacturer, importer, or responsible party can choose the most
appropriate phrase(s). For example, "Wear protective gloves/protective
clothing/eye protection/face protection" could read "wear eye
protection". C.2.4.3 When three full stops (-) appear in the precautionary statement text, they indicate
that all applicable conditions are not listed. For example, in "Use
explosion-proof electrical/ventilating/lighting/.../equipment", the use of "..."
indicates that other equipment may need to be specified. In such cases, the
chemical manufacturer, importer, or responsible party can choose the other
conditions to be specified. C.2.4.4 When text in italics is
used in a precautionary statement, this indicates specific conditions applying
to the use or allocation of the precautionary statement. For example, "Use
explosion-proof electrical/ventilating/lighting/.../equipment" is only required
for flammable solids "if dust clouds can occur". Text in italics is intended to
be an explanatory, conditional note and is not intended to appear on the
label. C.2.4.5 Where square brackets ( [ ] ) appear around text in a precautionary statement, this
indicates that the text in square brackets is not appropriate in every case and
should be used only in certain circumstances. In these cases, conditions for use
explaining when the text should be used are provided. For example, one
precautionary statement states: "[In case of inadequate ventilation] wear
respiratory protection." This statement is given with the condition for use "-
text in square brackets may be used if additional information is provided with
the chemical at the point of use that explains what type of ventilation would be
adequate for safe use". This means that, if additional information is provided
with the chemical explaining what type of ventilation would be adequate for safe
use, the text in square brackets should be used and the statement would read:
"In case of inadequate ventilation wear respiratory protection." However, if the
chemical is supplied without such ventilation information, the text in square
brackets should not be used, and the precautionary statement should read: "Wear
respiratory protection."

Sullivan, Ph.D.
Are the Precautionary codes associated with a chemical
determined on a case by a case basis or are they the same for all chemicals
with the same combination of GHS Hazard codes?
Thanks for any
information on this.
