Prior to each flight a safety check is conducted to ensure all equipment such as life-vests, flashlights and firefighting equipment are on board, in the right quantity, and in proper condition. Any unserviceable or missing items must be reported and rectified prior to takeoff. They must monitor the cabin for any unusual smells or situations and maintain certain precautions such as keeping doors disarmed or open during fuelling on the ground. They assist with the loading of carry-on baggage, checking for weight, size and dangerous goods. They then must do a safety demonstration or monitor passengers as they watch a safety video demonstrating the safety features of the aircraft. They then must "secure the cabin" ensuring tray tables are stowed, seats are in their upright positions, armrests down and carry on stowed correctly and seatbelts fastened
prior to takeoff. All the service between boarding and take-off is called Pre-Takeoff Service.
