Hydration

Dehydration can occur due to a variety of reasons such as vomiting, diarrhea, excessive sweating, and and even some medications. For Wildland Firefighters sweating is the primary way the body regulates its temperature. Maintaining body fluids is essential for sweating. You must hydrate before, during, and after work.

  • Studies conducted on wildland firefighters indicate that during fire suppression activities firefighters need to drink a minimum of one quart of fluid each hour of work.
  • Before work, you should consume extra fluids to prepare for the heat. Drink one or two cups of water, juice, or a sports drink before work.
  • While working, drink at least one quart of fluid per hour. Drink as much as you can during the lunch break. Water is your greatest need during work in the heat.
  • Hyponatremia (abnormally low concentration of sodium in the blood) as a result of excessive water intake is a potentially life-threatening complication. It can be prevented when hydration is enhanced by electrolytes, through fluids, or food containing sodium and potassium.
  • After work, it is important to continue drinking to replace fluid losses. Thirst always underestimates fluid needs, so you should drink more than you think you need.
  • Unacclimatized workers lose more salt in the heat, so they need to pay particular attention to salt replacement.
  • Don’t overdo salt intake. Excessive salt can impair temperature regulation and cause stomach distress, fatigue, and other problems.
  • You can assess your hydration by observing the volume, color, and concentration of your urine. Low volumes of dark, concentrated urine, or painful urination indicate a serious need for rehydration. Other signs of dehydration include a rapid heart rate, weakness, excessive fatigue, and dizziness.
  • Rapid loss of several pounds of body weight is a certain sign of dehydration. Rehydrate before returning to work. Working in a dehydrated state can lead to serious consequences, including heat stroke, muscle breakdown, and kidney failure.

Discussion Questions:

  • What are you doing right now to ensure that you are hydrated?

NWCG Standards for Rapid Extraction Module Support, PMS 552

Date: July 10, 2024
Contact: Incident Medical Unit Subcommittee 

A new publication from the Incident Medical Unit Subcommittee is now available. The NWCG Standards for Rapid Extraction Module Support, PMS 552 will be used as a guide and as an opportunity to begin to build out Rapid Extraction Module Support (REMS) modules for the remainder of Fire Year 2024. These standards will be fully implemented as the minimum standard starting in January 2025.

NWCG Standards for Rapid Extraction Module Support outlines the roles, duties, qualifications, and equipment pertinent to REMS. A REMS team, strategically stationed at wildland fires, plays a pivotal role in prioritizing swift access and medical treatment to injured or ill firefighters for safe and efficient egress off the fireline. This ensures their rapid transport to definitive medical care in cases of emergency during firefighting operations, highlighting the invaluable contribution of the REMS team to firefighter safety and well-being.

National Wildland Firefighter Day

Date: July 2, 2024
Contact: National Interagency Fire Center 

The National Wildfire Coordinating Group (NWCG) would like to recognize July 2, 2024, as National Wildland Firefighter Day (NWFFD). Established in 2022, NWFFD honors the dedication of wildland firefighters and support personnel. This day falls within the 2024 Week of Remembrance (June 30 - July 6), providing an opportunity to renew our commitment to wildland firefighter safety while remembering those who have fallen in the line of duty.

NWCG continues to provide leadership to enable interoperable wildland fire operations among federal, state, local, Tribal, and territorial partners. NWCG standards and training establish common practices to contribute to safe, effective, and coordinated national interagency wildland fire operations.
