As part of an asbestos management strategy, asbestos surveys are critical for assessing risks and preventing harm to persons who live or work in a building.
Asbestos Types Survey
Management surveys, pre-demolition surveys, and pre-refurbishment surveys are the three types of asbestos surveys.
Surveys of Management
This survey is useful for determining whether your facilities contain asbestos and developing an asbestos management plan. It does not
include any damage to the structure’s fabric, but it does include routine maintenance.
Specific invasive inspection points to impacted regions may be implemented during scheduled refurbishment works.
Surveys Prior to Demolition
When demolition work is planned on a property, pre-demolition surveys are required. To check for asbestos within the building fabric, a
fully intrusive inspection is required, as opposed to management surveys.
When a property is scheduled for refurbishment, pre-refurbishment surveys are conducted. This comprises a fully invasive inspection,
similar to pre-demolition surveys, although the scope of the work will be determined by the nature of the intended restoration.
An Asbestos Survey’s Methodology
An asbestos survey will begin with an initial walk-through during which the site will be risk assessed, plans will be examined, and any
other issues that may cause the project to stall will be found.
Asbestos surveyors utilise their knowledge to analyse the premises and locate any asbestos materials during a survey. This includes taking a sample to be tested in a lab and determining whether or not there is asbestos present.
Air testing may be performed as a precautionary step based on the results of an initial examination.
Reassurance air testing, background testing, and personal air testing are the three primary steps of an air testing procedure.
Reassurance air testing determines whether airborne fibres are present in a location following a specific operation.
Prior to the asbestos examination, background testing is performed to determine background asbestos levels.
Personal air testing must be approved by a trained asbestos consultant, who will establish whether or not the test is required based on work control procedures and risk assessments for the method.
Air tests are extremely useful because they detect asbestos-containing particles in the air by drawing in a known volume of air and quantifying the particles over time. Any airborne particles that are created in the filter are examined using microscopy.
