If a bed is temporarily downgraded from B to C should sampling continue until compliance with Class B criteria is met?
When a bed is temporarily downgraded under the third tier action state, two subsequent samples should be taken seven days apart. If these results are unsatisfactory (i.e. remain above 4600 but below 18000) then the bed will be placed on the three-month monitoring period. During this period sampling will revert to monthly monitoring. A risk assessment on the bed would need to be made if results above 4600 continue for the duration of the action state.
