General Questions (4)
Our FAQ's section has been designed to help you find quick and accurate answers to the most common question in relation to asbestos.
If you require any further assistance with regards to answering questions in relating to asbestos then please do not hesitate contact us.
The purpose of an asbestos survey includes:
* Identify the locations of ACMs
* Quantify the risk
* Provide recommendations
· Unrestricted number of samples
· Certificate of analysis
· CAD drawings that indicate the locations of where the samples have been taken (reference numbers from the certificate of analysis) · Photographic evidence
· Surveyors recommendations
To avoid any caveats within a survey report you will need to plan the survey with your preferred consultant, ensure that they have planned the work that enables access to all parts of the building. You are at liberty to refuse an asbestos report if the survey is incomplete or has not met you project objectives.

3- Crocidolite (blue)
The peak use for asbestos was between the 1940s and mid 1980s and during that time new towns and cities we either constructed or regenerated this meant a huge demand for asbestos products.
Asbestos used for insulation materials was initially prohibited in 1985 (2 & 3) and then followed by the banning of Chrysotile (1) in 1999.
There is now a total prohibition on the use and re-use of asbestos within the European Union and other developed nations.
People who worked in shipbuilding, railway engineering and asbestos manufacturing have a higher risk of continues exposure.
Secondary exposure was through people that either lived or traveled with people that worked in an asbestos environment, such as manufacturing, installation and transportation of asbestos products.
There are three main conditions that can occur from exposure to asbestos:
Asbestosis - is a chronic lung disease in which there is scar-like tissue formed in the lungs (pulmonary fibrosis). This fibrosis decreases the elasticity of the lungs, making breathing more difficult. Shortness of breath is the most common symptom. Development of asbestosis usually requires several years of exposure to asbestos fibres. The development and progression of asbestosis varies from individual to individual. It is often slow with little changes over five, ten or more years
Plural Plaques - - Inhalation of asbestos fibres can also lead to four types of non-cancerous abnormalities in the lining of the chest cavity (pleura). In many cases, the development of pleural plaques is not seen for 20 to 30 years after exposure. Pleural effusions (excess fluid between the two membranes that envelop the lungs) usually occur within 10 years after exposure.
Mesothelioma - - Malignant mesothelioma is an aggressive, usually fatal cancer arising from the mesothelial cells that form the lining of the pleural (lung), peritoneal (abdominal) and pericardial (heart) cavities. For mesothelioma, the latency is generally 30-40 years, with the longer periods seen where there had been lower levels of asbestos exposure.
Other Questions (7)
The answers on most common questions are described bellow.
A control limit is enforced by the HSE, no person can be exposed to asbestos that exceeds the control limit of .01 f/cc averaged over a four hour period.
Planning work with asbestos will include an exposure assessment, the assessment will determine the required controls to work safely with asbestos.
Any work that is likely to result in exposures at or above the control limit should be considered high risk and undertaken by a licensed contractor using appropriate controls.
