Readings under 9mg per 100ml of breath = OK to work
              Readings between 9mg - 15mg = Return for re-breathalysing in 2 hours – no site work to be carried out in this time.
              If after 2 hours, the result being blown is still over 9mg, no work to be carried out that day and worker to be given 1 strike. 
              Readings of 16mg and over = No work for the day and worker to be given 1 strike. 
              Each strike is recorded in the log and the individual should report to their Manager of AO. 
An accumulation of 3 strikes against one person will result in their dismissal.
