PIMEX for efficient working methods in the aluminium industry
July 2006 - December 2012
The HAPPA project has shown that the main part of total exposure for employees mainly happens in short periods of the working-day. This happens when dust and gas concentrations reach high values when the cells are opened for anode changing, by gas skirt changing and many other jobs. The behaviour based attitude of executing the jobs is assumed to give great difference in exposure. The exposure may be reduced considerably by regarding that such high concentrations occur. An educationally good method to analyze the job execution is important to obtain best practice.
In the proposal to framework directives from the Directorate of Labour Inspection in Norway to reduce the numbers of cases with potroom asthma, it is stressed as important to implement best practice and other organizing actions to reduce the exposure.
PIMEX has been used for production of a general training material focusing on dust exposure control in collaboration with WHO.
