HSR1 Courses As with Amy, I teach the HSR 1 & 2 courses, and have had a number of students who have done the course before come back, either through choice or through instruction by their company. If they are in a new role, and especially if they are in a new company then a lot of the course would be valid and interesting as they are applying their new situation to the activities and case studies. If they are in the exact same role, and especially if they have done both HSR 1 & 2 during the past 3/4 years, then I would look for another training course to send them on, for example Incident Investigation, Manual Handling, Managing Contractors, Mental Health & Wellbeing etc.
