Protective Equip. / Clothing

Emergency Response to a Suspected Ricin Incident: The following are possible PPE Levels for emergency responders based on scenario risks from highest level of protection to least: 1) Pressure-demand Self Contained Breathing Apparatus (SCBA) with Level A protective suit, when: a) Event is uncontrolled, b) The type(s) of airborne agent(s) is unknown, c) The dissemination method is unknown, d) Dissemination via an aerosol-generating device is still occurring, e) Dissemination via an aerosol-generating device has stopped, but there is no information on the duration of dissemination, or what the exposure concentration may be. 2) Pressure-demand SCBA with Level B protective suit, when: a) The suspected ricin aerosol is no longer being released, b) Other conditions may present a splash hazard. 3) Full-facepiece respirator with P100 filter or PAPR with HEPA filters, when: An aerosol-generating device was not used to create high airborne concentration. 4) Disposable hooded coveralls, gloves, & foot coverings, when: Dissemination was by a letter, package, or other material that can be bagged, contained, etc.
PPE recommendations for workers other than emergency responders must be developed in the HASP /health and safety plan/ for the specific scenario. PPE recommendations will vary by job type (e.g., cleanup, decon, etc.), type of exposure (e.g., airborne or surface/liquid/soil hazard), and any other site hazards (e.g., chemical, physical, etc.).
Personal Protective Requirements: Toxins are generally dispersed as aerosols and pose a severe respiratory hazard. However, Toxins are nonvolatile and do not pose an inhalation hazard once the aerosol has settled. Wear appropriate fully encapsulating protective gear with positive pressure self-contained breathing apparatus (SCBA). There is a significant hazard posed by contact of contaminated material with abraded skin or injection of toxins through contact with debris. Appropriate protection to avoid any potential abrasion, laceration or puncture of the skin is essential. /Toxins/
First Responders should use a NIOSH-certified Chemical, Biological, Radiological, Nuclear (CBRN) Self Contained Breathing Apparatus (SCBA) with a Level A protective suit when entering an area with an unknown contaminant or when entering an area where the concentration of the contaminant is unknown. Level A protection should be used until monitoring results confirm the contaminant and the concentration of the contaminant.
