This image displays an industrial construction hoist door, branded "ALIMAK," integrated into a concrete wall at a construction site in Aulnay-sous-Bois, France. The door comprises four rectangular, perforated orange metal panels within a grey metal frame. The upper left door panel features a safety poster titled "UN IMPRÉVU ? STOP!", depicting illustrated safety steps. The upper right panel bears a white sign in French, stating, "PLEASE REPORT TO THE SECURITY POST FOR THE OPENING OF THIS DOOR." Below this sign, a grey electrical control panel with green, black, and a red emergency stop button, along with associated black wiring, is mounted. A metal chain hangs from the right side of the door frame, and a yellow padlock secures a bracket on the adjacent concrete wall. To the left of the door, a circular sign with a crossed-out flame symbol prohibits "lift" use in case of fire. Faint grey markings resembling "H2O-S08" are visible on the concrete wall. Red electrical conduits are present above the hoist opening. The immediate ground in front of the door is a light grey concrete floor with minor debris. No individuals are present in the scene.
