Asbestos Risk Management
During a survey, an Asbestos Risk Assessment is carried out to assist in deciding the most appropriate action and in formulating a management plan. Initially, a Material Assessment is undertaken to assess the condition of the asbestos containing material and the risk it presents in releasing fibres if disturbed. Then a Priority Assessment is carried out to take into account maintenance activity, human exposure potential, occupant /visitor activity and subsequent likelihood of disturbance. Algorithms are used to score each factor which then results in an overall risk assessment score.
Asbestos (Material)Assessment Algorithms
Each factor is given a score; the value assigned is added to give a score of between 2 and 12. Materials attracting scores of 10 or higher are considered as having a high potential to release fibres and are therefore hazardous. Scores between 7 and 9 are considered as medium potential and scores between 5 and 6 as low. 4 and below offer a minor risk of contamination.
Asbestos (Priority) Assessment
Factors – location of materials, volume/extent, occupancy, use of area and maintenance profile.
