First Aid, CPR, and Aviation Emergency Response

Why First Aid and Emergency Response Matter in Aviation Maintenance

Aviation maintenance shops contain rotating machinery, high-voltage ground power units, flammable fuels, pressurized systems, and heavy components. A coworker can go from healthy to in cardiac arrest or severe hemorrhage in seconds. The FAA does not certify first aid skills directly, but OSHA requires employers to ensure prompt first aid is available, and every A&P technician is expected to act safely and competently in an emergency. Earning a recognized CPR/First Aid card from the American Heart Association (AHA) or the American Red Cross is your proof that you can.

Cardiac Arrest and the Chain of Survival

Cardiac arrest means the heart has stopped pumping effectively. Brain damage begins within minutes without oxygen delivery. The AHA describes a Chain of Survival: recognize the emergency and call 911, begin CPR immediately, use an AED as soon as one is available, and transfer care to advanced responders. Every link matters. If you skip the AED step because you do not know where the unit is, survival odds drop sharply. Know where your shop's AED is mounted before an emergency happens.

Hands-Only CPR vs. Full CPR

Hands-only CPR is appropriate for adult bystanders who witness a sudden cardiac arrest. Push hard and fast in the center of the chest—AHA guidance calls for a rate of 100–120 compressions per minute and a depth of at least 2 inches (but no more than 2.4 inches) for adults. Do not stop except to use the AED.

Full CPR with rescue breaths adds a 30:2 ratio—30 compressions followed by 2 breaths—and is recommended when you are trained and willing, especially for children, drowning victims, or anyone whose arrest was not witnessed. For a child (age 1 to puberty) compress at least one-third the depth of the chest, roughly 2 inches. For infants use two fingers and compress about 1.5 inches.

Allow full chest recoil between compressions. Incomplete recoil reduces the heart's refill and lowers output.

AED Operation

An Automated External Defibrillator analyzes heart rhythm and delivers a shock if a shockable rhythm is detected. Turn the unit on, follow its voice prompts, attach pads to bare dry skin (upper right chest, lower left side), ensure no one is touching the patient when it analyzes and shocks, and resume CPR immediately after each shock. AED trainer units provide the same prompts and feedback on compression depth and rate without delivering real electricity—use that feedback during practice to correct your technique before you need it on a real person.

Severe Bleeding Control

Uncontrolled hemorrhage is a leading cause of preventable death in trauma. The national Stop the Bleed initiative teaches three techniques:

1. Direct pressure – pack the wound with gauze or clean cloth and press firmly without releasing.

2. Wound packing – for deep wounds (stab injuries, shrapnel), push gauze into the wound cavity and maintain hard pressure for at least three minutes.

3. Tourniquet application – for life-threatening limb bleeding that direct pressure cannot control, apply a commercial tourniquet (such as a CAT or SOFT-T) two to three inches above the wound, tighten until bleeding stops, note the time on the tourniquet, and do not remove it. Target application within two minutes.

In a shop environment, a coworker's hand or arm can be caught in tooling. Know where your first aid kit and tourniquet are located.

PPE and Safety During Response

Blood and body fluids are potential biohazard exposures. Always don nitrile gloves before making contact with a patient if gloves are available. A face shield or pocket mask protects you during rescue breathing. After the emergency, follow your shop's exposure control plan for disposing of contaminated materials and reporting potential exposure. Remove gloves carefully (peel, do not snap) to avoid self-contamination.

Aviation Hangar Emergency Specifics

A hangar scenario adds hazards that a standard first aid course may not cover:

• Auxiliary Power Units (APUs) and ground power produce exhaust fumes and noise. Move the patient away from running equipment if it is safe to do so, or have a bystander shut down the APU using the established procedure.
• Jet fuel and hydraulic fluid on the floor create slip hazards for responders rushing to help.
• Crowd management – assign a specific person to call 911, a second person to retrieve the AED, and keep others back. Giving direct individual tasks prevents bystander paralysis.
• Aircraft doors and ladders may block EMS stretcher access; know alternate entry routes in your hangar.
• Communication – report to EMS the nature of the emergency, location in the facility, patient's approximate age and condition, and any hazardous materials present.

Earning Your Card

Your accredited provider (AHA or Red Cross) will evaluate your compression depth and rate (often using the AED trainer's feedback display), your AED steps, and your bleeding control technique. You must pass all required skill stations and a written or verbal knowledge check. The card you receive is your record; keep it and renew before it expires, typically every two years.
