AED Signs | Clarion safety Systems

Q: "What does an AED sign look like?"

"The international AED sign shows a white heart with a lightning bolt on a green square, standardized as symbol E010 in ISO 7010. A red heart version following NFPA 170 emergency symbol conventions is also common in North America."

Q: "Are AED signs required?"

"Requirements come from state AED laws, building codes and facility policies rather than a single federal rule, and they vary by location and occupancy type. Wherever an AED is installed, clear location signage is the recognized best practice, since the device only saves lives if it can be found quickly."

AED Signs That Make Defibrillators Findable in Seconds

When someone suffers sudden cardiac arrest, the people nearby have minutes to find and use the automated external defibrillator. AED signs exist for exactly that moment: marking the device's location so a stranger under stress can spot it from across a room, down a corridor or through a crowd. Clarion Safety's AED signs are available in the two standardized designs used across North America and worldwide, in wall-mount, projecting and flag-style formats that keep the location visible from every approach.

The ISO AED Symbol and the NFPA Red Heart: Two Standardized Designs

The green ISO sign uses the AED symbol standardized as E010 in ISO 7010: a white heart with a lightning bolt on a safety green square, the international safe condition color

The red heart sign follows the emergency symbol conventions of NFPA 170, the Standard for Fire Safety and Emergency Symbols, common in North American buildings

Both designs identify the same device; consistency within your facility matters more than which you choose. Placement follows the same logic as fire equipment signage: mount signs above the AED cabinet with clear sightlines, and add directional signs where the device serves large or divided areas. AED signs belong to your broader emergency wayfinding system alongside emergency signs and safety equipment location signs.
