Read the flight attendant manual for the type of plane on which you will be flying. Each plane has different levers, slides and numbers of doors.
Ask the head flight attendant if you have any concerns or questions about the doors. The head flight attendant, or "lead," has logged a certain number of hours on the plane according to the airline's regulations.
Approach the lead flight attendant for assignment during cross-check when the pilot requests everyone "prepare for cross-check." The lead will assign a flight attendant to do the initial check and another to follow behind to double-check the doors. For larger planes and larger crews, a few doors might be assigned to two flight attendants and the other doors to two other attendants. Often, these are divided between the front and the rear of the aircraft.
Check all your assigned doors upon landing or just before take-off. Before take-off you will ensure the slides are attached and the doors locked. Upon landing, you will detach the slides so when the door is opened at the gate the slide does not deploy.
