First aid is a skill for life. As its name implies, first aid is the help that you might give anyone who is injured or who suddenly becomes ill before the "second aid" arrives. The "second aid" refers to First Responders, Emergency Medical Technicians, paramedics, doctors, etc. EH&S recommends that all laboratories have a first aid kit, as it allows for the immediate care of the sick or injured person.
FIRST AID DOES NOT REPLACE A PHYSICIAN’S CARE. IF EMERGENCY ASSISTANCE IS NEEDED, NEVER HESITATE TO CALL 911.
