UK's initial operational response and specialist operational response to CBRN and HazMat incidents: a primer on decontamination protocols for healthcare professionals.

Emerg Med J 2018 Dec 1. Epub 2018 Dec 1.

Research Centre for Topical Drug Delivery and Toxicology, University of Hertfordshire, Hatfield, UK.

The UK is currently in the process of implementing a modified response to chemical, biological, radiological and nuclear and hazardous material incidents that combines an initial operational response with a revision of the existing specialist operational response for ambulant casualties. The process is based on scientific evidence and focuses on the needs of casualties rather than the availability of specialist resources such as personal protective equipment, detection and monitoring instruments and bespoke showering (mass casualty decontamination) facilities. Two main features of the revised process are: (1) the introduction of an emergency disrobe and dry decontamination step prior to the arrival of specialist resources and (2) a revised protocol for mass casualty (wet) decontamination that has the potential to double the throughput of casualties and improve the removal of contaminants from the skin surface.

Jason Hanna

Bioethics 2018 Nov 27. Epub 2018 Nov 27.

Philosophy, Northern Illinois University, DeKalb, IL, USA.

According to the causal theory of parenthood, people incur parental obligations by causing children to exist. Proponents of the causal theory often argue that gamete donors have special obligations to their genetic offspring. In response, many defenders of current gamete donation practices would reject the causal theory. Read More

Why Gametes are not Like Enriched Uranium.

Authors:
Andrew Botterell

Bioethics 2016 11 15;30(9):741-750. Epub 2016 Sep 15.

According to Rivka Weinberg, gametes are like enriched uranium: both are hazardous materials. Exposing human beings to enriched uranium can result in radioactivity and decreased life expectancy, while exposing sperm and ova to each other can result in the creation of needy innocent persons with full moral status. Weinberg argues that when we engage in activities that put our gametes at risk of joining with others and growing into persons, we assume the costs of that risky activity. Read More

Self-care Decontamination within a Chemical Exposure Mass-casualty Incident.

Prehosp Disaster Med 2015 Jun 27;30(3):288-96. Epub 2015 Apr 27.

Centre for Resilient Communities,Office of Applied Research,The Justice Institute of British Columbia,New Westminster,British Columbia,Canada.

Growing awareness and concern for the increasing frequency of incidents involving hazardous materials (HazMat) across a broad spectrum of contaminants from chemical, biological, radiological, and nuclear (CBRN) sources indicates a clear need to refine the capability to respond successfully to mass-casualty contamination incidents. Best results for decontamination from a chemical agent will be achieved if done within minutes following exposure, and delays in decontamination will increase the length of time a casualty is in contact with the contaminate. The findings presented in this report indicate that casualties involved in a HazMat/CBRN mass-casualty incident (MCI) in a typical community would not receive sufficient on-scene care because of operational delays that are integral to a standard HazMat/CBRN first response.

Transport Mode Selection for Toxic Gases: Rail or Road?

Risk Anal 2014 01 17;34(1):168-86. Epub 2013 May 17.

Desautels Faculty of Management, McGill University, Canada.

A significant majority of hazardous materials (hazmat) shipments are moved via the highway and railroad networks, wherein the latter mode is generally preferred for long distances. Although the characteristics of highway transportation make trucks the most dominant surface transportation mode, should it be preferred for hazmat whose accidental release can cause catastrophic consequences? We answer this question by first developing a novel and comprehensive assessment methodology-which incorporates the sequence of events leading to hazmat release from the derailed railcars and the resulting consequence-to measure rail transport risk, and second making use of the proposed assessment methodology to analyze hazmat transport risk resulting from meeting the demand for chlorine and ammonia in six distinct corridors in North America. We demonstrate that rail transport will reduce risk, irrespective of the risk measure and the transport corridor, and that every attempt must be made to use railroads to transport these shipments.
