Industrial safety sign with text 'BEFORE SAMPLING', 'ENGINE MUST BE OFF', 'DRIVER MUST EXIT THE VEHICLE', and an icon of a truck with a driver exiting and a crossed-out key.

Create a professional industrial safety sign in portrait orientation (A4 ratio). White background with a thick black border. At the top, a red banner spanning the width of the sign with large, bold, white uppercase text: BEFORE SAMPLING Below the banner, centered in very large, bold, black uppercase letters: ENGINE MUST BE OFF DRIVER MUST EXIT THE VEHICLE Between the two text sections, include a simple black silhouette safety icon showing a truck with the driver standing outside next to the open door. Add a red "engine off" symbol (key off or engine crossed out) beside the vehicle. Use a clean OSHA/ISO-style safety sign design with high contrast, sans-serif font (Helvetica or Arial Bold), ample spacing, and a layout suitable for printing on workplace signage. The overall appearance should be professional, highly legible, and compliant with industrial safety signage standards Ver mais
