The illicit use of fentanyl and its analogues is a serious public health concern due to the potency and wide availability of these substances. Hazardous materials teams must be able to effectively decontaminate fentanyl-contaminated areas and eliminate the risk of further contamination or unintentional exposure to emergency personnel and the public.
A recently published study in Nature presents new data on the most effective decontamination methods for fentanyl and carfentanil.
The findings of this study may be of interest to first responders in law enforcement, emergency medical services, or hazardous materials teams. The study focuses on effective decontamination methods that can minimize the risk of occupational exposure during operationally relevant scenarios, not just in a laboratory.
Because fentanyl and its analogues are highly toxic even in very small amounts, decontamination strategies based on chemical degradation are preferred over those based on physical removal alone.
This study reinforces previous studies showing that oxidative solutions are the most effective at chemical degradation of fentanyl and its analogues. The commercial product Dahlgren Decon was shown to be the most effective oxidative solution in this study. This product degraded fentanyl and carfentanil completely within 10 minutes.
For chemical degradation to be an effective decontamination strategy, the degradation products must be less toxic than the original products. Therefore, the study also investigated the physiological effects of the degradation products created with use of Dahlgren Decon and similar oxidative solutions. The results showed that these degradation products were much less toxic. They were significantly less potent in eliciting a response at the µ-opioid receptor level than fentanyl and carfentanil and they could be metabolized by liver enzymes.
Although Dahlgren Decon is an effective chemical degradation agent for fentanyl and carfentanil, it has several practical disadvantages such as high cost, the viscosity of the solution, accessibility, and ease of use (the three components must be mixed prior to use in the field).
This study explored several alternatives to chemical degradation via oxidative solutions, and it adds new data on dry decontaminants using metal oxides.
The commercial dry decontaminant FAST-ACT (first applied sorbent treatment against chemical threats), which consists of mixed aggregates of magnesium oxide (MgO) and titanium dioxide (TiO2) nanoparticles, was effective at decontamination in this study. Less than 5% of the fentanyl and carfentanil compounds remained after 10 minutes.
Additionally, an in-house synthesized titanium dioxide-based adsorbent was also shown to be effective for removal of fentanyl and carfentanil from solution. Less than 20% of fentanyl and carfentanil remained after 10 minutes.
The study suggests that metal oxide-based dry decontaminants could have potential for decontamination of fentanyl related substances under operationally relevant conditions.
The complete study is available as an open-access article in Nature.

The Federal Emergency Management Agency (FEMA) released the third edition of the National Disaster Recovery Framework (NDRF) this week.
The revised framework includes feedback and recommendations from the public during a 30-day public comment period that ended in October 2024.
The NDRF streamlines and clarifies the federal government’s approach to providing disaster recovery resources and support to disaster-impacted communities. It is one of five national planning frameworks for each of the five preparedness mission areas within the National Preparedness System – prevention, protection, mitigation, response, and recovery.
Key revisions include:
- Clarifying roles and responsibilities.
- Detailing the Federal Recovery Support Function structure and its role in supporting local recovery goals.
- Enhancing collaboration across the whole community.
- Providing practical resources to assist in recovery planning efforts.
FEMA encourages states, local governments, Tribal Nations and territories, as well as nonprofits and the emergency management community, to view and use the NDRF as a model to guide and inform their own disaster recovery planning and policymaking. The NDRF is valuable for recovery practitioners at all levels, ranging from full time professionals in state and county emergency management to individuals across the whole recovery community.
Access the third edition of the NDRF and associated Frequently Asked Questions document at FEMA.gov.

The 2025 Fire Department Instructors Conference International (FDIC International) is scheduled to take place April 7-12, 2025.
Fire Engineering magazine is hosting a webcast on Thursday, Dec. 19, at 1 p.m. EST, Bringing Drones to Fireground Operations. This webcast will offer a sneak peak of pre-conference classroom sessions that will be offered at FDIC International at the Indianapolis Fire Training Academy in April 2025.
The webcast focuses on how drones are changing the way firefighters operate and how drones can improve the safety and efficiency of fire service operations. Participants will learn about:
- How drones are used for search and rescue, scene monitoring, and real-time decision-making.
- Success and failure case studies.
- The recent deployment of drones during the 2024 Hurricanes.
- Lessons learned during the long-term deployment of Unmanned Aircraft Systems (UAS) platforms.
- Upcoming 2025 drone trends.
At the pre-conference in April, classroom sessions will include live field demonstrations where participants can see drones in action.
