If you become trapped in the lift press the bell button which will connect you by phone to the lift maintenance contractor [24/7/365]. Due to the height of the buttons above the floor smaller children should not use the lift alone. The button also rings a bell in the Ground floor lobby.
Do not hold the lift by blocking the door! It prevents use by others and may cause damage to the door mechanisms. Contractors working in your flat must be told not to overload the lift. If they use the lift for materials the interior of the lift must be protected against damage and cleaned after use.
