Measurements
Campaigns to measure the air concentration of asbestos fibres on and around the Hénâ slag heap are regularly carried out by the independent company SGS. The conditions imposed by the permit are 10 times more restrictive than those required by Belgian legislation. All measurements carried out to date show that the results comply with the imposed criteria.
