Snake Bites

 

Snakes are usually shy creatures that avoid human contact. Unfortunately, wildland firefighters are at risk of having contact due to their work environment. It should be noted that most snakes in the United States do not have venom. However, bites from non-venomous snakes can still cause significant infections and injury. Thus, it is best to avoid all snakes and bites when possible.

99% of envenomation from venomous snakes in North America are from the pit viper or Crotalidae family. This family includes copperheads, cotton mouth, and all varieties of rattlesnakes. The Crotalidae snake toxin is a complex mixture of proteases that essentially causes tissue destruction. Bites from any of these snakes are treated the same way and share the same antivenom.

The other venomous snake in North America is from the Elapid family, the coral snake. The coral snake is only found in small pockets throughout NM, AZ, TX, and southeast states. The coral snake toxin affects the central nervous system and requires a different antivenom.

Approximately ½ of all venomous snake bites are “dry”- meaning the snake does not secrete any venom. When venom is injected, the amount varies considerably based on the area of contact, last feeding, and other variables. However, any time a firefighter is bitten by a snake, it should be assumed that it was a venomous snake, that a significant amount of venom was secreted, and they should be evacuated. Once at a hospital it can be determined what course of action is needed. Delaying treatment to determine the type of snake or if symptoms will develop may cause significant harm.  

If bitten by a snake:

  • Assume it is venomous.
  • Do not try and catch or kill the snake.  This often results in secondary bites.
  • Clean the area with mild soap and water if possible.
  • Keep the area below the level of the heart.
  • DO NOT tightly wrap the area or apply constrictive dressings.
  • Get transported to the nearest emergency department in a timely fashion.

In the emergency department the patient will be evaluated, and it will be determined if antivenom is necessary. Other treatments may include tetanus vaccination, antibiotics, and local wound care. 

Discussion Questions:

  • What are the types of dangerous snakes that are found in the area you are working now?
  • When your crew identifies a snake, what actions do you take to advise others and avoid contact?

RMC Safety Bulletin 26-001: Rhabdomyolysis in Wildland Firefighters

Date:  May 28, 2026
Questions? 
Please contact: Risk Management Committee

The Risk Management Committee (RMC) has issued Safety Bulletin 26-001: Rhabdomyolysis in Wildland Firefighters. Research from 2016 to 2025 shows that 88 cases of rhabdomyolysis (rhabdo) were reported. Analysis of reports from eSafety, the Safety Management Information System (SMIS), and the Wildland Fire Lessons Learned Center (LLC) indicates that rhabdo is common during this time of year due to Work Capacity Tests and contributing factors such as weather, hydration, nutrition, and medication or supplement use.

RMC issued this safety bulletin to raise awareness in the Wildland Fire Community, and to provide research findings and educational resources that support reducing future cases of rhabdo.
