- Wash the bite with soap and water.
- Immobilize the bitten area and keep it lower than the heart.
- Cover the area with a clean, cool compress or a moist dressing to minimize swelling and discomfort.
- Monitor breathing and heart rate.

- It is helpful to let the emergency room staff know what kind of snake bit you. So try to remember what the snake looks like, its size, and the type of snake, if you know it. Take a picture of the snake if you can do so safely.
- If the snake is dead, bring it to the emergency room. However, be aware that a snake can still bite for up to an hour after it is dead.
- Do not apply a tourniquet.
- Do not attempt to suck the venom out.

Snake Safety Tips
Rattlesnake sightings are rare, and bites are even rarer because generally, rattlesnakes avoid humans. Still, it's important to be aware of these potentially lethal creatures when enjoying Utah's outdoors. Most venomous snakebites occur when people try to catch, kill, pick up, or harass a snake.
Utah's Division of Wildlife Resources has these tips for avoiding a snakebite:
- If you encounter a rattlesnake while hiking, remain calm. Do not panic.
- Stay at least five feet from the snake. Give the rattlesnake respect and space.
- Do not try to kill the snake. Doing so is illegal and greatly increases the chance the snake will bite you.
- Alert people to the snake's location. Advise them to use caution and to respect the snake's space. Keep children and pets away.
