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?

LMC Equipment Bulletin 26-001: Aquatic Invasive Species – Seasonal Reminder for Mussels

Date:  July 30, 2026
Questions? 
Please contact: Equipment and Technology Subcommittee

The Logistics and Equipment Management Committee (LMC) issued Equipment Bulletin 26-001: Aquatic Invasive Species - Seasonal Reminder for Mussels, reminding the wildland fire community that aquatic mussels continue to be a problem. Mussels rapidly colonize hard and soft surfaces, including aquatic plants and fire equipment, clogging pipes, fouling motors, disrupting water systems, and impacting native species.

To help prevent their spread, fire personnel must follow the decontamination procedures outlined in the NWCG Guide to Preventing Aquatic Invasive Species Transport by Wildland Fire Operations, PMS 444. Additionally, report any sightings immediately to your Lead Resource Advisor and include clear, close-up photos (with a pen or your hand for size reference) and location details.”

Read the complete LMC Equipment Bulletin 26-001, to learn more.

Intermediate Faller (FAL2) Position Task Book Update

Date:  July 24, 2026
Questions? 
Please contact: Tree Felling Subcommittee

NWCG Operations Management Committee (OMC) has issued an update to the NWCG Position Task Book for Intermediate Faller (FAL2), PMS 311-91. To ensure clarity for both trainees and evaluators, the updated FAL2 Position Task Book (PTB) explicitly states who is authorized to sign off on your tasks:

“Evaluators must be qualified as a FAL2, or an Advanced Faller (FAL1).”

If you are currently working out of a previously published version of the FAL2 PTB, you do not need to restart. However, OMC highly encourages you to take the following step to prevent any confusion in the field:

  • Print and replace the updated evaluator information page (page 2) in your current physical PTB.
