Health Risks:
Amosite asbestos has been banned in the UK and many other countries as the fibres and dust can cause serious lung conditions if inhaled. Any handling of material containing amosite asbestos should be done only by those who are trained and properly equipped in its handling and disposal.

Collectors who have small samples of Amosite or other asbestos minerals are advised to keep them in sealed plastic boxes where they are, of course, perfectly safe.
