The care of the sick and injured on wildland fire incidents has expanded over the last 30 years. The mission of Medical Units on wildland fire incidents has evolved into a complex service which provides: (1) stabilization and emergency medical treatment of incident personnel, and (2) occupational health and preventative measures for incident personnel to remain safe and healthy. Wildland firefighting operations require a unique array of services due to the remoteness, terrain, and complexity of utilizing multiple agencies. Medical support is essential because of the inherent risks and exposures associated with these events. The issues of standard of care and legal licensure of providers come into play when emergency medical providers from other jurisdictions cross state lines or other geopolitical boundaries to provide medical care. These situations are further complicated in areas where medical control is sometimes nonexistent or the capabilities of nearby medical facilities may be limited, including the variability of local emergency medical services agency capacities. This document introduces stakeholders to the minimum standards developed by the Incident Emergency Medical Task Group (IEMTG) when a Medical Unit has been established by a National Wildfire Coordinating Group (NWCG) member agency. This document is intended to provide direction regarding medical personnel and equipment assigned to the Medical Unit. The IEMTG recognizes the National EMS Scope of Practice Model as the baseline standard for emergency medical service providers. Therefore, a key component of the minimum standards addresses the recognition of local, state, federal, and tribal jurisdictional authorities and the integration of medical services. Overall, the minimum standards seek to ensure that incident personnel receive quality, timely medical care on wildland fire incidents, which often occur in remote areas.
