“FDA issues warning on masks worn for COVID protection. Someone’s face got burned”
“The FDA issued a safety warning about masks on Wednesday, specifically for people having an MRI during the pandemic: If the mask has metal in it, don’t wear it during the screening.
Someone has already come out of a neck MRI with facial burns.
“The report describes burns to the patient’s face consistent with the shape of the face mask,” the alert said. “Burns from metal objects worn by a patient during an MRI exam are a known issue, and patients should not wear any metal during an MRI.”
Before you dismiss the warning, check out the many places your mask might have metal beyond the nose clip.
In addition to the nose clips or wires, the FDA notes, “nanoparticles (ultrafine particles), or antimicrobial coating that may contain metal (such as silver or copper), may become hot and burn the patient during an MRI.”’
Contamination by respiratory viruses on outer surface of medical masks used by hospital healthcare workers
“Respiratory pathogens on the outer surface of the used medical masks may result in self-contamination. The risk is higher with longer duration of mask use (> 6 h) and with higher rates of clinical contact. Protocols on duration of mask use should specify a maximum time of continuous use, and should consider guidance in high contact settings. Viruses were isolated from the upper sections of around 10% samples, but other sections of masks may also be contaminated. HCWs should be aware of these risks in order to protect themselves and people around them.”
