When checking for scene safety, the use of the acronym "ADD" can help identify dangers that would prevent the safe use of an AED.

A - Airway: Check for any obstructions in the person's airway, such as vomit or foreign objects. If the airway is blocked, it must be cleared before using an AED.

D - Danger: Look for any potential hazards in the environment that could pose a risk to the rescuer or the victim, such as live electrical wires, open flames, or traffic. If there is any danger present, it must be eliminated or mitigated before using an AED.

D - Device: Check the AED to ensure it is functioning properly and has sufficient battery power. If the AED is not working or does not have enough power, it cannot be used safely.
