The NPPTL issued a June 2022 notice PDF for ADG FlexAirPAPRs. AirBoss Defense Group (ADG) FlexAir powered air-purifying respirators (PAPRs) This notice details the models impacted and actions you should take to ensure your SCBA contain the proper filters. If filters are missing from the reducer, the potential exists that the user could experience a leak at the reducer seat retainer.

3M Scott has received reports on the Air-Pak X3, Air-Pak X3 Pro and X3-21 Pro models referencing the primary and/or secondary reducing valves missing certain high pressure air filters. The NPPTL issued a May 2022 notice PDF for 3M Scott SCBA Air-Pak models manufactured between Nov. 3M Scott SCBA (Self-Contained Breathing Apparatus) Air-Pak models * OSHA/NIOSH Interim Guidance (April 2005).The National Institute for Occupational Safety and Health (NIOSH) National Personal Protective Technology Laboratory (NPPTL) has posted 2 user notices that may impact certain respirators used by fire and emergency medical services providers. Provide information on voluntary use of PPE Suggest means for reporting suspected contamination Inform people of location of event and Red and Yellow Zones NOTE: transient, minimal contamination potential does exist within the Green Zone Select PPE and limit work duration to reduce risk of contamination and exposureĪreas where contamination with CBRN agents is unlikelyĪreas beyond expected dispersal range of initial eventĪreas beyond contamination range created by traffic and emergency responders Take advantage of natural ventilation to reduce contaminationĬomplete a mandatory radiation survey and assisted or self-decontamination upon exitĪreas known to be contaminated with CBRN agentsĪreas in which active release has ceased and initial monitoring information exists Protect valuable property necessary for public welfare, initial monitoring)Īvoid unnecessary contact with surfaces or potentially contaminated materials.Level A PPE until risk assessment allows for change/downgrade in PPE level Emergency worker exposure guidelines in the early phase of a radiation incident Control Zone CategoryĪreas confirmed to be contaminated with life-threatening dermal and/or inhalational toxinsĪreas suspected to be contaminated with life-threatening dermal and/or inhalational toxins (pending confirmation).Various agencies and radiation control programs have developed other systems for site control.Use of control zone categories is not mandatory nor exclusionary of other site control concepts.PPE selection determined by anticipated threats to life and health within a given control zone.Control zone categories may be used as complimentary guidance for selecting PPE.Categorized by color (red, yellow, green) according to level of risk.Not for use in environments containing less than 19.5% (i.e., low) oxygen Not for use in areas characterized as immediately dangerous to life and health Whenever making entries into environments containing less than 19.5% (i.e., low) oxygenĪfter characterization of response scene identifies lower risk of potential internal contamination Whenever inhalational hazards are unknown/uncharacterized or expected to be high Self-contained breathing apparatus (SCBA) During initial emergency operations NIOSH-certified CBRN-approved respiratory protective equipment may be in limited supply, especially in large events.NIOSH-certified CBRN air-purifying respirators ( APR).NIOSH-certified CBRN powered, air-purifying respirators ( PAPR).NIOSH-certified self-contained breathing apparatus ( SCBA).Respiratory protective equipment used by first responders in CBRN-contaminated environments must be tested and certified by NIOSH and may include:.Guidance on Respiratory Protective Equipment Appendix B: General description and discussion of the levels of protection and protective gear describes PPE to be used by workers entering contaminated environments (including respiratory protective equipment).Emergency response to CBRN events regulated by OSHA's Hazardous Waste Operations and Emergency Response (HAZWOPER) Standard: 29CFR1910.120.Exposure monitoring is complicated or unavailable in real-time.Typical indicators of exposure are absent (e.g., no obvious odor, smoke, or fume).
