Pollution control hierarchy and equipment
The selection and deployment of environment protection equipment and techniques is based on breaking the source–pathway–receptor linkage. At any potentially polluting incident there may be opportunities for positive intervention aimed at disrupting this linkage.
In most circumstances the hierarchy of pollution control aims to contain polluting materials at the earliest opportunity to minimise the quantities lost and spread of contamination. This is used to bring order and control to an event using wherever possible existing resources and facilities at the incident with the deployment of carefully selected pollution control equipment. The principle behind this approach is that the more dispersed the pollutant, the more difficult it will be to recover.
ll five stages of the hierarchy require a dynamic risk assessment to be undertaken within the parameters of an appropriate safe system of work and appropriate personal protective equipment (PPE) being worn as recommended by the Emergency Action Code system.
