This document outlines several risks associated with filming in an underground parking garage and proposes mitigation strategies. It notes that the cold temperature could cause hypothermia or pneumonia if characters are thinly clothed. To address this, filming is limited to less than an hour and coats are worn during sitting scenes. Being locked in could also be dangerous if the cold exposure was prolonged, but the filming time is kept short. Phones allow contact with the person who holds the exit key. Dragging a character across the concrete floor risks injury, so a coat is worn to prevent skin damage from friction. Fake violence scenes between characters also carry injury risks, so soft landing areas and controlled force are used.
