Signs of Snake Bite

First Aid

Workers should take these steps if a snake bites them:

• Seek medical attention as soon as possible (dial 911 or call local Emergency Medical Services [EMS]).
  • Antivenom is the treatment for serious snake envenomation. The sooner antivenom can be started, the sooner irreversible damage from venom can be stopped.
  • Driving oneself to the hospital is not advised because people with snakebites can become dizzy or pass out.
• Take a photograph of the snake from a safe distance if possible. Identifying the snake can help with treatment of the snakebite.
• Keep calm.
• Inform your supervisor.
• Apply first aid while waiting for EMS staff to get you to the hospital.
  • Lay or sit down with the bite in a neutral position of comfort.
  • Remove rings and watches before swelling starts.
  • Wash the bite with soap and water.
  • Cover the bite with a clean, dry dressing.
  • Mark the leading edge of tenderness/swelling on the skin and write the time alongside it.

Do NOT do any of the following:

• Do not pick up the snake or try to trap it. NEVER handle a venomous snake, not even a dead one or its decapitated head.
• Do not wait for symptoms to appear if bitten, get medical help right away.
• Do not apply a tourniquet.
• Do not slash the wound with a knife or cut it in any way.
• Do not try to suck out the venom.
• Do not apply ice or immerse the wound in water.
• Do not drink alcohol as a painkiller.
• Do not take pain relievers (such as aspirin, ibuprofen, naproxen).
• Do not apply electric shock or folk therapies.
