freedom from ambiguity and contradiction as possible. As a result, they are expressed in a number of ways, though this number has been kept to a minimum. It is necessary to keep this variety of expression in mind when searching or interpreting Schedule entries.
Firstly, poisons are scheduled individually using their approved names wherever practicable although exceptions are necessary in some cases. Some of those are mentioned below. Older group entries are revised and replaced by individual entries as time permits, although in some of these cases a group term has also been retained to deal with any members of the group or class that may have escaped attention but should be scheduled.
Secondly, Schedule entries have been expressed in either positive or negative terms and care must be taken to distinguish between the 2 different forms of expression. Thus, selenium is in Schedule 6 only when one of the clauses in this Schedule entry applies, while fluorides are in Schedule 6 unless one of the exempting clauses applies.
Where exceptions are included in an entry, these have been emphasised by printing the word "except" in bold type.
Where the Schedule entries for a poison make a specific exclusion or exemption, the requirements of this instrument do not apply to that poison within the constraints of that exclusion or exemption although controls under other legislation, such as pesticide registration, may apply.
Where a Schedule entry for a poison requires a specific statement to be included on a label as a condition for a product to qualify for an exemption ("reverse scheduling"), then in cases where it is impracticable for a supplier to use the exact wording of such a statement, its wording may be varied provided that the full intent and meaning of the statement is not changed.
Where a poison has been included in more than one Schedule, the principal entry, where practicable, has been included in the most restrictive Schedule with references to the other Schedule(s) involved.
It is important to remember that a Schedule entry includes preparations containing the poison in any concentration and all salts and derivatives of the poison unless it specifically states otherwise (see section 7).
It is important to note that a substance is not classed as a derivative on the basis of a single, prescriptive set of criteria. Classification of a substance as a derivative of a scheduled poison relies on a balanced consideration of factors to decide if a substance has a similar nature (e.g. structurally, pharmacologically, and toxicologically) to a scheduled poison or is readily converted (either physically or chemically) to a scheduled poison. However, a substance is only considered a derivative of a scheduled poison if it is not
