Wear gloves to prevent contact with the victim’s blood. Put on gloves before you begin first aid. If gloves are not available, use a thick dressing, clean cloth, or even the victim’s hand as a protective barrier.

If you are trained in CPR (cardiopulmonary resuscitation) to use chest compressions and rescue breathing, use a special facemask to give rescue breathing.

Wash your hands with soap and water right after giving first aid. Use an alcohol-based hand sanitizer if soap and water are not available.

Be alert for downed power lines, raging fire, fast-moving water, or hazardous materials, which may make it dangerous to offer first aid.

Call the professionals if the scene is dangerous.

Move toward the victim only if the scene appears safe.

Look for clues as you approach. Identifying the cause of the emergency may help you respond with the appropriate first aid.

Look for hidden victims. An infant or unconscious person can be easy to miss.

Call 911right away if you are not trained in first aid. If you are trained and giving first aid, clearly direct another person to call 911.

Contact emergency medical services right away if you’re not able to offer first aid or if serious injuries are present. In most parts of the country, calling 911 will connect you with an emergency services dispatcher.

Call zero (0) if 911 service is not available in your area. The telephone operator can connect you with fire and police departments and ambulance service.

Tell the dispatcher the following:

• Your exact location

• What happened

• The number of victims

• The condition of each victim

• Any first aid being provided

• Don't hang up unless you are told to

Speak to the victim and tap them on the shoulder. If the person does not respond, start rescue techniques immediately. If the person does respond, continue with the following steps.

• Control any severe bleeding. (Wear gloves or use other protection to avoid contact with the victim’s blood.)

• Look for medical alert tags around the victim’s neck, wrists, and ankles. These can let you know if a person has a health condition such as seizures or problems with blood sugar (diabetes). Knowing this can help you or other first responders apply appropriate aid.

• Check for other injuries.

• If it appears that the victim was in a traumatic accident, try to keep them from moving, especially the neck. The person may have an injury to the spine that could cause spinal cord damage if moved.
