While the provided documents do not specify the exact height for AED box placement, they do offer some general guidance on accessibility and safety regarding electrical equipment that may be helpful when deciding on the height placement of an AED.

Consider these points:

• Accessibility: Ensure the AED is readily accessible to those who need it. Consider the reach of potential users [1], and ensure the height is suitable for a wide range of individuals.
• Clearance: Maintain adequate clear space around the AED to allow for easy operation [1]. The documents specify minimum clearance around electrical equipment to allow for safe operation and maintenance 1, 8, 9. While an AED is not electrical equipment, similar principles of clear access could be applied.
• Guarding Live Parts: If the AED or its related electrical components have any exposed live parts, ensure they are guarded against accidental contact, especially by unqualified persons [2]. One method of guarding is elevation of 8 feet or more above the floor 1, 20.
• Warning Signs: If the AED is placed in a location with potentially exposed live parts, ensure there are conspicuous warning signs 17, 20.

It would be best to consult local regulations or guidelines for specific requirements on AED placement in your area.
