Information to assist the Shopper, Budget Holder and Specialist Approver determine the appropriate Hazard Levels for requisitions made on behalf of the University. This page also explains what checks should be carried out by both the Budget Holder and the Specialist Approver as part of their responsibilities for managing the introduction of lab and workshop equipment and machinery which have hazard potential into the University. The hazards in particular include lasers, X-rays, electromagnetic radiation (EMF) and sealed sources (internal standard).
|Low||Medium||High||Budget Holder Responsibility||Specialist Approver Checks||Pre-release checks|
Lab or workshop equipment that contains a sealed source (e.g. as an internal standard);
X-ray generating equipment from main suppliers;
Class 1, Class 1M, Class 2 Lasers
Static magnetic field <2 Tesla external to the source
Magnetic flux density <0.4 mTesla external to the source
Class 1 Laser Product;
Class 2M and Class 3R Lasers;
Static magnetic field >2 Tesla external to the source;
Magnetic flux density >0.4 mTesla external to the source
X-ray Generators designed and/or built by staff or by small suppliers;
Class 3B or Class 4 Lasers;
Static magnetic field >5 Tesla external to the source;
Magnetic flux density >1.2 mTesla external to the source.
To determine the correct Hazard Level has been assigned.
To ensure that the space that the equipment is to be located is suitable and that any additional safeguards such as interlocks, etc have been considered.
To ensure that in-house design mitigates risks to health, safety and the environment.
To ensure that persons that will be involved in the use of the equipment become suitably trained.
To consider future disposal implications.
Budget Holder must ensure that there are local rules established and followed.
For HIGH Hazard Level requisitions, formal documentation will need to be submitted to the Radiation Protection Officer.
To obtain assurance that the checks have been made by the Budget Holder. This may involve confirming that the proposed location for the equipment is suitable and that local rules are in place or are being drafted by the Budget Holder.
The Specialist Approver to consult if necessary with the Radiation Protection Officer for HIGH Hazard requisitions.
Normal workflow including Specialist Approval.
