Signs of Snake Bite
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 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.
