Photograph of a sign hanging in a window by an entryway of the Edith O'Donnell Arts and Technology (ATEC) building at the University of Texas at Dallas (UTD). The sign is blue with divided colored sections in order from top to bottom: red, orange, yellow, green. The red section reads "high risk of transmission," the orange section reads "extreme caution," the yellow section reads "proceed carefully," and the green section reads "new normal until you're vaccinated." The top of the sign contains white text in capital letters that reads "Today's COVID-19 risk level" and the bottom of the sign contains white text in lowercase letters that reads "dallascounty.org/covid-19/" as well as a small black and white logo.

Photograph of a stand up sign with a large poster attached that is turquoise colored and features dark green text in capital letters, an orange header with white text in capital letters, and a dark green footer with white and orange text in capital letters and the University of Texas at Dallas logo. The large poster shows a faceless cartoon person with dark hair and a white face mask. The large poster reads, "For your health, we encourage everyone to wear a mask indoors." Behind the large poster, the image reveals a white building interior with a staircase and large windows in the distance. To the right of the sign in the image, there is a smaller A4 size paper sign posted to the wall with the image of a cartoon hand and a hand sanitizer disposal underneath the sign. The small paper sign reads "Please use hand sanitizer before entry."
