Jobsite AED Programs

Sudden cardiac arrest can strike any worker. Chances of survival drop about 10 percent for every minute without CPR and a shock from an automated external defibrillator (AED). On sites far from help, a prepared AED program can mean the difference between life and death.

• Employers
• Safety Managers
• Crews

Do you need one?

• OSHA does not generally require AEDs, but recommends them in many workplaces. Some states, cities or contracts do require them for certain buildings and sites.
• If workers are far from medical help, or the work is strenuous, hot or around electricity, an AED is a strong choice. See Remote Site Emergencies.
• OSHA's first aid rule says that if medical help is not nearby, someone must be trained in first aid. See First Aid vs. Medical Treatment.

Program elements

• Choose approved devices with simple voice prompts. Make sure pads fit adults and, if needed, children
• Place AEDs where they can be reached within about 3 minutes (a few minutes' walk) from any work area, visible and unlocked or in an alarmed cabinet, with signs. On sites, put them in trailers and keep them with crews in vehicles
• Train workers in CPR and AED use, and refresh as required. Include shift coverage, subcontractors and supervisors
• Maintain devices: check the readiness light or status indicator regularly, expiry dates for pads and batteries, and extreme temperatures. Keep a log. Keep spare pads, a razor, trauma shears, gloves and a towel
• Have a written response plan: who calls 911, who gets the AED, who starts CPR, who meets responders and how to give directions. See Emergency Action Plans
• Notify local EMS of the AED, where required, and report any use
• Check state law and medical oversight or registration rules

Using an AED

1. Check the scene is safe, check responsiveness and breathing. Call 911 and send someone for the AED.
2. Start CPR: push hard and fast in the center of the chest, 100 to 120 compressions per minute. See CPR & AED.
3. Turn on the AED and follow the voice prompts. Remove clothing from the chest, dry it if wet, and apply the pads as shown.
4. Stand clear while the AED analyzes and, if advised, delivers a shock. Resume CPR immediately.
5. Continue until emergency responders take over or the person responds.
