THE DUTY TO MANAGE.....
The current 'Control of Asbestos at Work' Regulations (CAWR) have introduced the duty to manage asbestos risk in commercial, industrial or public properties.
The regulation requires those who own, occupy or manage premises  (i.e. any person by way of contract or tenancy who has an obligation of any extent in relation to the maintenance or repair of such premises) to develop strategies in regulating the risk of exposure to asbestos in the workplace.
