You are the supervising manager for the 6 p.m. to 2 a.m. shift at a hotel. At 1 a.m. your maintenance crew chief reports the strong smell of something burning in the third-floor corridor. However, no guest has complained and the fire alarms are silent, with all sensors throughout the building, including the third floor, showing "green" for no problems. You must decide what to do next. Is your situation best described as an incident, an emergency, a crisis, or a disaster?
