MONTREAL: "The Quebec government is asking school boards, daycares and health networks to stop using a type of mask that Health Canada warned can be toxic to the lungs. People have even been asked to "immediately store the boxes of masks in a secure and isolated location" after the alarming warning.

The grey and blue masks are identified by the code SNN200642 and are from the supplier Metallifer, the province said. According to a statement provided to CTV News, the province distributed 30.6 million SNN200642 masks to networks under the ministry of family, education and higher education. Since January, the province has distributed 116 million masks to the school network, 4.6 million of which were of the SNN200642 line.

In a notice Thursday, a Health Canada director wrote of "a potential emerging risk" with face masks coated with nanoform graphene materials. The agency "identified a potential for early pulmonary toxicity associated with the inhalation of nanoform graphene," it wrote. It considers the risk the masks pose to be "unacceptable." In a statement, Metallifer said its company does not manufacture the masks, and that when it imported the products from China, they "were fully qualified at the time."
