Materials Descriptions and Hazard Level

When preparing a requisition, or approving a requisition on the OPeRA system, (or other accepted procurement method), it is important that the hazard potential or Hazard Level of the item being ordered is considered at the requisition stage and that the risks are duly managed once the item is introduced into the University.

Training in the use of the OPeRA system and access to a Full User Manual can be obtained from the OPeRA pages within the IT Services webpages.

A 'walk through guide' has also been prepared to show you how to alter the relevant Hazard Level and assign the relevant Material Code within the OPeRA system.

The following table will assist anyone to determine the Hazard Level for Material Descriptions which have been identified within the OPeRA system as having a hazard potential and should be used to support decision making at the requisition and approval stages withn the OPeRA workflow:
