Part II CONCENTRATION LIMITS TO BE USED IN APPLYING THE CONVENTIONAL METHOD OF ASSESSING HEALTH EFFECTS IN ACCORDANCE WITH PART I OF THIS SCHEDULE WHERE NO SUCH LIMITS ARE GIVEN IN THE APPROVED SUPPLY LIST

An assessment must be made of the health effects that the use of a substance or a preparation might entail. For that purpose the dangerous health effects have been subdivided into:—

• acute lethal effects;

• non-lethal irreversible effects after a single exposure;

• severe effects after repeated or prolonged exposure;

• corrosive effects;

• irritant effects;

• sensitizing effects;

• carcinogenic effects;

• mutagenic effects; and

• teratogenic effects.

The systematic assessment of all the dangerous health effects is expressed by means of concentration limits in conjunction with the classification of the substance, i.e. the symbol and risk phrases which are assigned to each substance under consideration.

In relation to solid and liquid preparations references in this Part to percentage concentrations shall be treated as references to those concentrations on a weight/weight basis.
