Forty seven questionnaires were received from companies, in all of the categories listed above, though not all of the specific types of product were covered by the replies. One of the questionnaires was incomplete and so the results from this have not been included. Two companies sent two completed questionnaires from different employees, and one manufacturer sent three completed questionnaires from different employees, since the replies in each case were slightly different, none of these questionnaires have been removed from the results.
