a 25 minute slot within a staff awareness day is not by any stretch "training." You'd do well to cover fire safety, housekeeping standards and availability of Risk Assessments for significant activities across all Departments. Introduce yourself and cover your role, and your expectations of those you work with. Keep it light and use lots of pictures.

Hi I work in a Uni too, each year for staff training I have to bring something for 20 Mins. This year I took a small section of a topic on housekeeping. I got staff to go round the halls of residence and collect all shoes and anything left on the corridors. Then they thought I had put them in a smoke filled corridor in which I asked them to walk through. (I had really put them in a bedroom on that corridor). But we had fun. Now residential staff ask students to keep corridors clean reducing trip hazards. In the past I have done the evacuation chair, and got staff to have a go. I have done the importance of hand washing ( especially during first term when illness flood the halls of residence) I have borrowed equipment to show staff how who have not washed properly. I done epidemiological studies and presented PowerPoint graphs. I have even done a quiz.
