Special provisions in Schedule 1

Special provision means an item of Schedule 2 referred to in Column 5 of Schedule 1.

Schedule 2 gives the text of the special provisions that apply to dangerous goods; the numbers of the special provisions in Schedule 2 correspond to the numbers in Column 5 of Schedule 1. Each UN number that has the special provision against it is included in italics at the end of each special provision.

When there is a special provision in Schedule 2 for dangerous goods, that special provision applies.

If there is a conflict between a special provision in Schedule 2 and other provisions in the regulations, the special provision applies.

When the regulations do not apply to specific dangerous goods, then Schedule 2 does not apply.
