    Automatic Doors and COVID-19

    Automatic doors serve an essential purpose in healthcare facilities and more broadly across our communities: providing touch free access and egress. As the COVID-19 crisis unfolds, this purpose is even more critical. Through our joint efforts of providing, maintaining, and servicing automatic door equipment, our industry is helping to minimize the transmission of this and other harmful viruses which could otherwise be spread through the touching of contaminated door knobs, handles, etc.

    Automatic Door Technicians, particularly AAADM Certified Automatic Door Inspectors, are on the front lines of ensuring proper operation and maintenance of these critical touch free access devices – working in healthcare facilities and other high-traffic areas where the risk of COVID-19 transmission may be elevated.

All individuals are expected to take actions to reduce risk of transmitting the COVID-19 virus, and we thank the automatic door technicians for their key role in ensuring proper operation of touch free automatic door access devices.
