    Science of Safety Podcast.

    Episode 95:
    CBRN respiratory protection - Part 2.

    In this episode, host Mark Reggers and guest Professor David Crouch, 3M’s Global Subject Matter Expert – Application Engineering (Defence & Public Safety) continue where they left off and resume their discussion on respiratory protection related to chemical, biological,radiological and nuclear hazards.

    CBRN is an acronym for Chemical, Biological, Radiological and Nuclear. It is a terminology used worldwide that refers to malicious incidents or weapons in which any of the four types of hazards mentioned are used to cause significant harm or disruption. It encompasses the protective measures taken in these situations and consists of passive protection, contamination avoidance and mitigation.

      

             

        

    Guest Bio:

    David Crouch (pictured left) has an extensive background in Chemical, Biological, Radiological and Nuclear (CBRN) remediation processes and technologies, having worked with numerous international agencies and the private sector. A professional chemist, with more than 25 years’ experience in the fields of materials science, respiratory protection and CBRN decontamination science. David is also a chartered chemist, Fellow of the Royal Society of Chemistry and Fellow of the Institute of Civil Protection and Emergency Management.

    Prior to his current role David spent more than a decade focused on CBRN decontamination related topics at Pursuit Dynamics PLC and the University of Manchester concentrating primarily on novel decontaminant design and aerosol delivery technologies for CBRN remediation. Professor Crouch has completed degrees in Applied Chemistry (BSc(Hons)), Business Administration (MBA), Strategic Defence Studies (MA) and a PhD (Materials Science – Organic Photonics), Co-authoring 50 Peer reviewed publications and patents.

    In this episode, Mark & David discuss the following:

     
    • What should a CBRN respirator contain?
    • Should a CBRN respirator be supplied air (SCBA), positive pressure with filters (PAPR) and/or negative pressure with filter (RR)?
    • What does it mean when we talk about interoperability and CBRN respirators?
    • For air purifying CBRN respirators that use filters, what type of filter is used? Is it one type of filter for all CBRN hazards?
    • Are there different standards and tests for CBRN respirators compared to traditional industrial respirators?
    • Is fit testing required for tight-fitting CBRN respirators?
    • Do you have any examples of military/law enforcement/first responder CBRN product configurations suitable for the specific hazards and risks they may face?
    • What takeaway point would you want to leave with our listeners?
    • Where can the listeners go and get further information about what we have discussed today?
    • How can our listeners get in contact with yourself?

    CBRN hazard responses need to be appropriate to the threats. When it comes to respiratory protection, you need to be prepared for everything and anything. It’s about understanding the hazards and the appropriate response from a PPE perspective, one that takes into consideration the hierarchy of control and hazard assessment. The key to this is realistic, real-time and regular training to understand what pieces of equipment you need for these very high risk, diverse and malicious environments. Tune in as we navigate CBRN respiratory protection, a specialist high-risk area that is quite different in comparison to conventional industrial programmes.
