Venomous snakes found in the United States include rattlesnakes, copperheads, cottonmouths/water moccasins, and coral snakes.
They can be dangerous to outdoor workers including farmers, foresters, landscapers, groundskeepers, gardeners, painters, roofers, pavers, construction workers, laborers, mechanics, and any other workers who spend time outside. Some workers with a severe allergy to snake venom may be at risk of death if bitten.
Its been estimated that 7,000–8,000 people per year receive venomous bites in the United States, and about 5 of those people die.
The number of deaths would be much higher if people did not seek medical care in a timely manner.
It is important for these outside workers to train themselves about their risk of exposure to venomous snakes, how they can prevent and protect themselves from snake bites, and what they should do if they are bitten. Also, one of the things a worker should be aware of is what these venomous snakes look like.
