At what height should medical emergency symbols be attached to the hoistway door frame?

Medical emergency symbols should be attached to the hoistway door frame at a height no less than 66 inches. This height is designed to be prominently visible and easily identifiable by emergency responders, ensuring that they can quickly locate the elevator in case of an emergency. Placing the symbols at the specified height helps to standardize the visibility across various elevator installations, making it easier for first responders to recognize potential medical emergencies that may occur within the elevator system. Ensuring that such critical information is positioned at an accessible and observable height can significantly enhance the safety measures within the building's infrastructure.
