If you come upon an accident, activate the Emergency Medical System (EMS) to insure
prompt response. Then apply four first aid rules:
Protect yourself from possible injury or infection - use barrier devices
such as gloves and a mask.
Start the breathing. If the injured person has stopped breathing,
start artificial respiration right away. Do not stop until another qualified
person relieves you or the victim is breathing normally.
Stop the bleeding. Most bleeding can be stopped by pressing down
on the wound. If possible you should place a gauze pad, a clean cloth or even
your fingers (if wearing protective gloves) will have to be used. Bleeding
from an artery should always be stopped first. The blood from an artery will
be bright red and will come out of the wound in spurts. If the blood is darker
in color and flows evenly, it is from a vein. Once the gauze or cloth is in
place - DO NOT REMOVE IT.
Treat for Shock. Persons who have been injured may go into shock.
When someone is in shock, all of the body functions slow down. Shock can be
very serious. It can cause death. Shock may develop right after a crash or
later. Injured persons must be treated for shock regardless of whether or
not they appear to be in shock.
Reassure the injured person. Your calmness will help. Do not give them
anything to drink.
Cover the person with blankets or coats to hold body heat. Have the person
Keep onlookers back so that the injured person has air.
Keep their head as low as possible unless there is a head injury.
Loosen tight collars to make breathing easier.
DO NOT MOVE AN INJURED PERSON IF THE PERSON CANNOT MOVE OR
COMPLAINS OF PAIN IN THE BACK OR NECK OR HAS A HEAD INJURY.
DO NOT ATTEMPT TO REMOVE THE HELMET OF AN INJURED MOTORCYCLE RIDER.
USE PRUDENT CARE AND GOOD JUDGEMENT. WORK ONLY WITHIN THE SCOPE OF CARE YOU
ARE TRAINED TO PROVIDE.
