One of the ever-present features at a race meeting are the ambulance officers.  They are there to respond to any accidental injuries that might arise from the racing and/or handling of the horses.  At metropolitan tracks they also attend trackwork sessions each morning. 

On most occasions there are no incidents to respond to, but nonetheless they are always available should an incident arise.

In a similar way, much of the chaplain's role involves being available to respond as needs arise. In addition to this, an important part of the chaplain's role is to visit the injured and/or to provide other (non-medical) assistance when accidents happen.  The good working relationship that exists between chaplains and ambulance personnel is therfore a great bonus.
