Want some tips for staying safe while riding in an elevator? Harvard Chan School environmental health expert Joseph Allen recommends that when riding an elevator, you should: (1) wear a mask, (2) load in a checkerboard pattern and maximize space, (3) face forward, (4) announce your own floor, (5) let one person push the buttons, (6) don't talk, (7) try not to sneeze or cough, (8) if you do, turn toward the wall and sneeze into your elbow, (9) move aside to create a clear exit for others. | Harva
