Focus Hands On Practical Module

Foreword

The decontamination of buildings from CBR contamination requires specially trained and extremely competent technicians and contractors. The safety, speed, economics and clearance procedures require universal training and understanding well outside the usual parameters of contracting and management. This module provides the technician with hands on practical training which can only be undertaken following successful completion of relevant technical and academic modules.
