I know that this includes all employees but we are a Work Based Learning Training Provider in Engineering Apprenticeships and have learners who are employed by other companies but who attend our workshops and participate in work based activities for a minimum of one day every week. For example at one centre we have three trainers who tutor at least ten learners per day (i.e. 50 learners per week), giving me an exposure element of 112.5 hours per week for employees and 375 hours for learners employed by other companies.

If a learner were to encounter an injury whilst on our premises it would count in our statistics - therefore I would assume that their exposure hours would also count when calculating accident statistics. We have had several Health & Safety Managers over the past couple of years who have had varying opinions on this issue.

I would be interested in feedback with your opionion on this issue.
