AED Placement on Evacuation Plans: Travel Distance, Signage and Integration with Emergency Response

Automated External Defibrillator placement is governed by a patchwork of standards. The American Heart Association's 2015 Guidelines for CPR and ECC recommend that AEDs be placed where the expected response time from collapse to defibrillation is 3 to 5 minutes or less. The Occupational Safety and Health Administration (OSHA) does not directly mandate AEDs but encourages workplace AED programs in its 2001 Best Practices Guide. State laws vary widely: California (AB 658), New York (General Business Law Section 627-a), Illinois and many other states require AEDs in specific occupancy types — health clubs, schools, sports facilities, public buildings — and provide Good Samaritan immunity to AED users. The ADA requires accessible mounting. Federal Aviation Administration requires AEDs on commercial aircraft over a certain size. The International Building Code does not require AEDs, but the IFC and NFPA 1 are starting to reference them. For evacuation planners, the standard is to follow the AHA 3-minute response-time recommendation and any applicable state mandate, treating the AED as an essential piece of life-safety equipment that belongs on the posted plan.

The 3-minute response time is the total elapsed time from cardiac arrest collapse to first AED shock delivery. The components are: bystander recognition and call for help (~30 seconds), travel to retrieve the AED, travel back to the victim, AED setup and pad placement (~30 seconds), AED analysis and shock decision (~10 to 15 seconds). For AED travel time, the typical walking speed is 200 to 250 ft/min in an unobstructed corridor. Allowing roughly 60 to 90 seconds for the round trip to retrieve the AED, the AED should be located within approximately 1.5 minutes round-trip walking time of any expected cardiac arrest location — typically 150 to 250 ft along the path of travel from any point in the building, with a single AED per floor for small buildings and multiple AEDs strategically located in large buildings. Mall and large public-assembly AED placement is typically calculated for the worst-case foot-traffic location, often near food courts, escalators or entrance lobbies. The plan should mark each AED location and, ideally, the responder should be able to identify the nearest AED at a glance from any location on the plan.

AEDs are typically mounted in dedicated AED cabinets at 48 inches above the floor to the handle — within the ADA reach range and accessible from a seated position. Cabinets are usually wall-mounted in alcoves or shallow recesses that do not project into the egress corridor. Many cabinets have an integral alarm that sounds when the cabinet is opened, alerting nearby staff that a cardiac event is in progress. Signage is critical: the international AED symbol (ISO 7010 E010 — green square with white heart and lightning bolt) is the universal mark, and AHA recommends a high-mounted directional sign visible from across the room or down the corridor so the AED can be spotted from a distance. Many facilities supplement with a 'AED Inside' sign on the cabinet face, plus arrow signs at corridor intersections pointing toward the AED. AED cabinet manufacturers offer through-the-wall recessed cabinets that maintain rated wall assemblies without protruding into corridor egress width — important in fire-rated corridors where ADA protrusion limits also apply (4 inches maximum projection).

AEDs require routine maintenance: monthly visual inspection of the readiness indicator, replacement of pads at expiration (typically every 2 years), replacement of batteries at expiration (typically every 4 to 5 years), and post-use inspection and supply replenishment. AEDs that have been used must be returned to ready status immediately. Many states require facility AED programs to maintain documentation including the placement plan, maintenance log, training records of designated responders, and the medical-direction agreement with a physician overseer. Some AED programs use cellular-connected AEDs that auto-report battery and pad status to a centralized dashboard, alerting facility management when maintenance is required. The posted evacuation plan does not include maintenance status, but it should reflect the actual current AED locations — if an AED is added, moved or retired (after a use or end-of-life), the plan needs to be updated. AED relocations are particularly common after a facility renovation, when an AED that was previously in a now-defunct corridor needs a new home; the plan must follow.

AEDs are typically co-located with comprehensive first aid kits and bloodborne pathogen (BBP) cleanup kits, since cardiac events often have an associated mess (vomit, blood from a fall) that responders need to manage and clean up after EMS arrival. OSHA 29 CFR 1910.151 requires first aid supplies in workplaces where no infirmary is nearby (Appendix A references ANSI Z308.1 first aid kit content). The first aid station, AED and BBP kit form an integrated emergency-response package that should be located near high-occupancy areas (cafeterias, gyms, large open offices, entrance lobbies). The posted plan should mark all three with the appropriate icons (AED — green heart-and-lightning-bolt; first aid — green cross; BBP — biohazard symbol). Eye-wash stations, emergency showers and AED locations often coincide in industrial and laboratory occupancies — the plan should show them all so responders can find both the cardiac and chemical-exposure equipment in one place. In healthcare occupancies, code-blue carts (which include AED capability) replace standalone AEDs and have their own placement standards driven by Joint Commission and CMS requirements.

Although AEDs are designed for laypersons and Good Samaritan laws cover untrained users in most U.S. jurisdictions, organized facility AED programs typically maintain a roster of designated responders — staff who receive CPR + AED training and respond to medical emergencies in the building. The AHA's BLS for Healthcare Providers and Heartsaver CPR/AED courses are the standard credentials. State law in some jurisdictions (e.g., New York Section 3000-b) requires that AED programs maintain a list of trained users, designate a physician medical director, and report each AED use to the medical director and local EMS for quality review. Many corporate facilities run quarterly AED drills alongside fire drills, simulating a cardiac arrest and timing the AED retrieval and pad-placement sequence. The posted evacuation plan should identify the AED locations clearly enough that even an untrained bystander can find the nearest AED quickly — the icon plus a high-mounted directional sign in the actual building is the typical solution.

EvacPlan Generator (www.evacplangenerator.com) provides an AED icon in the medical-equipment category of the standard symbol library, plus icons for first aid stations, emergency showers, eye-wash stations and BBP cleanup stations. The planner places one AED icon at each installed AED location on the floorplan. The 150-to-250-foot travel-distance check (the practical proxy for the 3-minute response time) can be performed visually by inspecting that no point on the floor is more than that distance from an AED icon, walking along corridors rather than measuring in a straight line. The MAP KEY automatically includes AED in the legend once an AED icon has been placed on the plan, so a viewer of the plan immediately knows what the green heart-and-lightning-bolt icon represents. For multi-floor facilities, each floor's plan shows that floor's AEDs, and the planner can include a note in the legend pointing to the stairwell for cross-floor access if needed. When AEDs are added, moved or retired, the plan can be updated and reprinted in minutes — the same revision workflow that handles fire extinguisher and pull station changes handles AED changes seamlessly.
