Asbestos is a naturally occurring mineral that was commonly used in the construction industry up until the late 1990s. It was prized for its resistance to heat and fire, as well as its insulating properties. However, over time it has become clear that asbestos is also extremely hazardous to human health if it is inhaled. Asbestos fibres are very fine and can easily become airborne, where they can be breathed in by anyone nearby. Once in the lungs, these fibres can cause a range of health issues including lung cancer, asbestosis, and mesothelioma.
