Topic Collection: Chemical Hazards
An incident involving the accidental or intentional release of chemicals can lead to death or serious illness and injuries, hospital surge, and the need to protect responders, medical care providers, and community members. The resources in this Topic Collection are specific to chemical agent patient evaluation and treatment and can help emergency responders and healthcare workers identify chemical hazards and prepare for, respond to, and treat survivors of related incidents. Please note: While ASPR TRACIE works closely with subject matter experts to ensure we provide the most up-to-date information; this field and related treatment/antidote information is constantly evolving. If you are a clinician treating a patient, please check the U.S. Department of Health and Human Service’s Chemical Hazards and Emergency Medical Management (CHEMM) webpage, and/or your local poison control center.
Related information can be found in the CBRN Resources page and the following Topic Collections (listed alphabetically): Hospital Patient Decontamination, Mass Distribution and Dispensing of Medical Countermeasures, On-Scene Mass Casualty Triage and Trauma Care, Pediatric, Pre-Hospital Patient Decontamination, and Responder Safety and Health.
Each resource in this Topic Collection is placed into one or more of the following categories (click on the category name to be taken directly to that set of resources). Resources marked with an asterisk (*) appear in more than one category.

The Primary Response Incident Scene Management (PRISM) series is comprised of three volumes that can help ensure that patients exposed to potentially hazardous chemicals receive the most effective treatment possible during the initial stages of an incident (after prompt decontamination). Updated in 2019, PRISM incorporates new scientific evidence on emergency self-decontamination, hair decontamination, the interactions of chemicals with hair, and the effects of a combined decontamination strategy referred to as the “triple protocol.” The clinical research showed that these three steps, taken together, remove 99.9 percent of chemical contamination.

The author discusses deficiencies of existing triage systems for use with chemical agent attack casualties. He proposes a rapid-triage system for chemical warfare agents to “identify those classes of agents that require rapid treatment with antidotes, emergency airway support, and spot decontamination, and then further delineate within that group the class of agent that is present so that the correct antidote can be given.”

The authors used data from the 2005 Graniteville, SC chlorine spill to evaluate the appropriateness of 5 commonly used triage systems for assessing casualties from chemical events.

A massive leak of liquefied chlorine gas created a dangerous cloud over the city of Henderson, NV, in the early morning hours of May 6, 1991. Over 200 people (including firefighters) were examined at a local hospital for respiratory distress caused by inhalation of the chlorine and approximately 30 were admitted for treatment. ASPR TRACIE interviewed Chief Bruce Evans (who was a firefighter-paramedic at the time of the incident), asking him to share his experiences and highlight how the

Several local health departments participated in a review of the response to the 2014 methanol spill. Interagency communications and public risk communications were listed as challenges, and participants shared that, for example, flushing recommendations were not practical for hospitals (they suggested that in future incidents, hospitals be treated as separate from the business community.)

The authors summarize the emergency medical services response to the attack, including challenges and strengths. They recommend that responders have access to mobile decontamination facilities in similar events. Chemical effects on responders were significant. Though many effects were psychogenic in nature, the mere perception of harm rendered responders less effective (another reason why responder access to personal protective equipment for chemical events is so important).

The authors conducted a literature review of 50 articles related to prevention and treatment of respiratory problems induced by sulfur mustard. They found that most treatments were directed at symptom alleviation, and that oxygen supplementation, tracheostomy in laryngospasm, use of moist air, respiratory physical therapy, mucolytic agents and bronchodilators used in the acute phase led to improved lung injury outcomes.

While the traditional treatment for this type of poisoning has been intravenous atropine and oxime (e.g., pralidoxime and obidoxime), the practicality of oximes has been disputed by physicians across the globe. Based on literature reviews, the authors conclude there is not enough evidence either way and emphasize the need for further research.

The author discusses deficiencies of existing triage systems for use with chemical agent attack casualties. He proposes a rapid-triage system for chemical warfare agents to “identify those classes of agents that require rapid treatment with antidotes, emergency airway support, and spot decontamination, and then further delineate within that group the class of agent that is present so that the correct antidote can be given.”

The authors share results of a pilot test that measured a triage system for patients exposed to chemical, biological, radiological, or nuclear contamination. They found that while the algorithm could be applied by trained paramedics, there was a significant under-triage rate and more research needs to be conducted.
