This list may be broad or very niche and will determine what control measures you put in place.
Consider not just committee but all attendees, volunteers, members of the public, etc. Consulting with members or staff can help to identify who is at risk.
Certain hazards may pose more risk to certain groups of people e.g. those with medical conditions, pregnancy, under 18’s. You may wish to consult with your members about how best to approach a certain risk to enable them to participate in an activity.
