If you cannot, stay in your room and call the operator or security to let them know you are in your room. • Put your hand on the room door to see if it is hot before opening it. If it is, do not open it quickly. Open it just a crack to see what is on the other side and be prepared to slam it shut quickly if necessary. “Diseases may not be fashionable topics in this world • If you leave the room, take your room key with you! of perennial beauty, but they are real, and this book Shut your room door to keep smoke out.
