Training objective
TARGET: Technical departments of machinery manufacturers.
OBJECTIVES: The training covers the entire AT 1 programme. It goes on to illustrate the methodology for correct risk analysis and reduction in the presence of a potentially explosive atmosphere. Electrical” protection methods such as intrinsic safety or explosion-proof enclosures are detailed. The risk of ignition due to shock, friction or electrostatic charge is also analysed.
DURATION AT 2: 8 hours (AT 1)+ 8 hours= 16 hours
