What should be the first action taken if asbestos is suspected in a building?

The initial action when asbestos is suspected in a building should involve conducting a risk assessment and testing. This step is crucial because it allows for the identification and evaluation of potential asbestos-containing materials (ACMs) in the structure. Before any further action is taken – including renovations, notifications, or emergency responses – it is essential to confirm the presence of asbestos and assess its condition.

Testing will not only determine if asbestos is present but will also evaluate whether it poses a risk to health, particularly if the materials are disturbed or deteriorating. This scientific approach ensures that decisions are based on solid evidence rather than assumptions, which is vital for ensuring the safety of workers and occupants. After the assessment, informed decisions can be made about appropriate handling, abatement strategies, and communications to those potentially affected.

The other options would be premature and could potentially exacerbate safety risks. Continuing renovations without understanding the risk may disturb ACMs and release fibers into the air, calling the fire department may not be relevant unless there is an immediate threat, and notifying building tenants before confirming the presence of asbestos could cause unnecessary panic without factual basis.
