Personal protective equipment – including N95 masks – for healthcare professionals are in short supply, and some nurses in Michigan are attempting to address the shortfall by supplying their own masks – but, their employer, The University of Michigan Health System, is saying no, reports Michigan Live.

“Because we cannot guarantee PPE acquired elsewhere is clean, properly fitted, and meets FDA requirements, Michigan Medicine will not permit our team members to use masks brought from home in our facilities,” according to Mary Masson, a spokeswoman for the hospital.

Union leaders are working to ensure more PPE is allowed into the hospital regardless of source. “We have had many, many people who have been willing to go out and with their own funds, spend a lot of money to purchase equipment, so that they can take care of these patients,” says Katie Oppenheim, the nurses’ union chairwoman. “Because of course, that’s what we want to do. We want to take care of these patients, nobody’s saying they don’t want to do it, they just want to be safe.”
