What color should the glass-fronted box for the emergency valve be painted?

The glass-fronted box for the emergency valve should be painted red because the color red universally signifies urgency and danger. This color is an established standard in many safety protocols, signaling that the contents within the box are critical and require immediate attention in an emergency situation. Using red helps ensure that the box is easily noticeable and recognizable during times of crisis, which can be crucial for quick responses and safety measures.
