reg 5 Assessment of risks
In the case of any activity likely to involve a risk of exposure to asbestos, the employer must— (a) in carrying out the risk assessment required by regulation 7 (risk assessment) of the General Duties Regulations— (i) determine the nature, degree and duration of the workers' exposure in order to make it possible to assess any risk to the workers' health or safety and to lay down the measures to be taken, (ii) in assessing the risk of such exposure, take account of all routes of exposure, and (iii) give particular attention to any effects concerning the health and safety of workers at particular risk and take account of the desirability of not employing such workers in areas where they may come into contact with asbestos, and (b) review the assessment regularly and in any event where there is reason to believe that it is incorrect or when any change occurs in the conditions which may affect workers' exposure.
