When to seek emergency care

Call 911 or your local emergency number if the injured person experiences:

  • Severe burns
  • Confusion
  • Difficulty breathing
  • Heart rhythm problems (arrhythmias)
  • Cardiac arrest
  • Muscle pain and contractions
  • Seizures
  • Loss of consciousness

Take these actions immediately while waiting for medical help:

  • Turn off the source of electricity, if possible. If not, move the source away from you and the person, using a dry, nonconducting object made of cardboard, plastic or wood.
  • Begin CPR if the person shows no signs of circulation, such as breathing, coughing or movement.
  • Try to prevent the injured person from becoming chilled.
  • Apply a bandage. Cover any burned areas with a sterile gauze bandage, if available, or a clean cloth. Don't use a blanket or towel, because loose fibers can stick to the burns.
