Hill sprints can be very extreme and tough training.
Experience in running/sprints/conditioning etc will be required to be ready for hill sprints. If in very bad condition or having any other health related problems, hill sprints are not where to start.

Check the surface before running (smooth without stones or holes in it) Always warm up properly with jogging, muscle activation/dynamic exercises...
Next step is a few warm up sprints (not full intensity). Then ready to go!
