Birck Safety Protocols

It is very gratifying to see our research community back ‘in business’ doing leading-edge research in our center after the long pause we all experienced this Spring.  But at the same time we want to remind our entire user group of the critical importance of following the COVID safety protocols while using our facilities.  If an outbreak of COVID exposures should happen at Birck there is a real possibility that we may need to close the facility again.  So please read and support the following…..

…..Some of our approved users are holding the doors open for others to enter the building.  This may very well be a gesture of politeness to assist another, but it also can be perceived that non-approved people are entering our building with the assistance of one of our approved users.  Additionally it does not allow us to have an accurate accounting of who is entering our building by evaluating card-swipe data.  So everyone should swipe into Birck and not be let in by someone holding the door open.

…..Face masks are required while in Birck.  Approved users have been, and continue to be, strongly encouraged to bring their own face mask for their personal use while in the facility.  At the entrances we have supplied quantities of disposable face masks for emergency use, but our supplies of these disposable masks are being depleted at the high rate of 300 – 400 masks per week.  This rate of use seems exceptionally high when personal masks are strongly recommended.  Please only take one mask from the supply, and only when you’ve forgotten your personal mask.

….Social distancing continues to be a challenge.  This is a difficult habit to develop and groups of people have been seen clustered around a tool, or having a hallway conversation, and not adhering to the 6’ spacing rule.  Please continue to maintain at least 6’ spacing between yourself and the nearest other person.

Please stay vigilant in promoting and supporting these safety protocols.  If we each do our part we will continue to stay open and conduct state-of-the-art research in our great facility.
