To determine the correct Hazard Level has been assigned.

To ensure that there are suitable storage facilities.

To ensure that the location and facilities where it will be used are suitable for the hazards it presents.

To consider impact on existing waste streams.

Budget Holder must ensure that there are sufficient storage facilities for working with the material, that the environment is suitable for their use and that local rules are established and followed.

For all Departments (except Chemistry):

For MEDIUM and HIGH Hazard materials, the Specialist Approver must obtain assurance that the checks stated have been made by the Budget Holder. This may involve confirming that the facilities are suitable and sufficient and that local rules are in place or are in the process of being drafted by the Budget Holder.

The Specialist Approver will only be required to undertake the above checks for HIGH Hazard category items in the Chemistry Department.

Finance Officers to ensure authorised 'named' Budget Holders are.....

Chemistry Department: the Head of Department of Chemistry can authorise 'named' Budget Holders to approve requisitions of LOW and MEDIUM Hazard Level Chemicals.

In all other Departments the Head of Department can authorise 'named' Budget Holders to approve requisitions of LOW Hazard Level Chemicals only. Specialist approval to be used for MEDIUM and HIGH Hazard Level requisitions.
