Asbestos Diagnosis Before Work or Demolition

Within the framework of work or demolition, it is a question of carrying out a specific identification which consists in identifying the materials of lists A, B and C. The search for these materials can be done by destructive sampling or dismantling.

Various mandatory diagnoses adapted to each situation.

As soon as real estate transactions (sale, rental), property management activities (condominiums, professional premises) or renovation/rehabilitation or demolition works are undertaken, it is essential to detect asbestos by means of asbestos diagnoses which differ according to the context but which are all intended to protect the population from any exposure risk.


In all cases, each asbestos search, i.e. detection of asbestos and control of its state of conservation if necessary, is oriented on one or more lists of materials and products containing asbestos appearing in the Public Health Code.




Important to know about the DTA

The DTA must be kept up to date and available for consultation by any person occupying the building. The Asbestos Technical File (DTA) must also be given to any company intervening for work before the intervention in order to protect its staff.
