The public health workforce is diverse and encompasses a wide range of professions. For tribal communities, the Community Health Representative (CHR) is a public health paraprofessional whose role as a community health educator and health advocate has expanded to become an integral part of the health delivery system of most tribes. CHRs possess a unique set of skills and cultural awareness that make them an essential first responder on tribal land. As a result of their distinctive qualities they have the capability of effectively mobilizing communities during times of crisis and can have a significant impact on the communities' response to a local incident. Although public health emergency preparedness training is a priority of federal, state, local and tribal public health agencies, much of the training currently available is not tailored to meet the unique traits of CHRs. Much of the emergency preparedness training is standardized, such as the Federal Emergency Management Agency (FEMA) Training Programs, and does not take into account the inherent cultural traditions of some of the intended target audience. This paper reports on the use of the Native American Talking Circle format as a culturally appropriate method to teach the Incident Command System (ICS). The results of the evaluation suggest the talking format circle is well received and can significantly improve the understanding of ICS roles. The limitations of the assessment instrument and the cultural adaptations at producing changes in the understanding of ICS history and concepts are discussed. Possible solutions to these limitations are provided.
According to the National Fire Protection Association there were 487,500 structural fires in the U.S. in 2013. After visible flames are extinguished firefighters begin the overhaul stage where remaining hot spots are identified and further extinguished. During overhaul, a significant amount of potentially hazardous chemicals can remain in the ambient environment. Previous research suggests that the use of air purifying respirators fitted with chemical, biological, radiological, and nuclear (CBRN) canisters may reduce occupational exposure. This study used large scale burns of representative structural materials to perform side-by-side, filtering, and service-life evaluations of commercially available CBRN filters using two head forms fitted with full-face respirators and a dynamic breathing machine. Three types of CBRN canisters and one non-CBRN cartridge were challenged in repetitive post-fire environments. Tests were conducted with two different breathing volumes and rates for two sampling durations (0-15 min and 0-60 min). Fifty-five different chemicals were selected for evaluation and results indicate that 10 of the 55 chemicals were present in the post-fire overhaul ambient environment. Acetaldehyde and formaldehyde were found to be the only two chemicals detected post filter but were effectively filtered to below ACGIH TLVs. Counter to our prior published work using continuous flow filter evaluation, this study indicates that, regardless of brand, CBRN filters were effective at reducing concentrations of post-fire ambient chemicals to below occupational exposure limits. However, caution should be applied when using CBRN filters as the ambient formaldehyde level in the current study was 8.9 times lower than during the previous work.
