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).CBRN agents manifest toxicity by dual routes (e.g., skin and inhalation).Emergency responders enter increasingly toxic or hazardous OSHA Control Zones.Higher levels of protection may be required when:.Assessment of risk to emergency responders.OSHA/NIOSH Interim Guidance provides technical advice and information to incident commanders regarding personal protective equipment (PPE) selection for all-hazards CBRN event response.Guidance on Respiratory Protective Equipment.If you have additional questions about Respirator Pre-submission Tests – NIOSH testing, or would like to consult with the experts at Nelson Labs, just send us a request or call us at +1 (801) 290-7500.OSHA/NIOSH Interim Guidance - April 2005 * - Notes on PPE Selection Matrix for Emergency Responders In addition to NaCl and DOP tests, mask manufacturers may be required to demonstrate inhalation, exhalation, and valve leak tests in conformance with 42 CFR Part 84 and NIOSH procedures. Inhalation, Exhalation, and Valve Leak Tests The filtration requirement for HEPA filters is 99.97% at 0.3 µm using the DOP test. Samples can be tested at flow rates up to 90 liters per minute (LPM). Test articles are challenged with particles of the most penetrating particle size range, 0.3 µm.įiltration efficiency measurements can be determined up to 99.999%. The procedure employs an aerosol of DOP using a TSI® CERTITEST® Model 8130 Automated Filter Tester. The DOP aerosol test is a widely accepted method for evaluating particle penetration and air flow resistance properties of a variety of filtration materials (e.g., breathing system filters, NIOSH respirators and face masks). Test articles submitted for testing according to NIOSH requirements will be tested according to 42 CFR Part 84 “Approval of Respiratory Protective Devices.” Dioctyl Phthalate (DOP) Challenge Test articles intended to be resistant to oil (R-series) or oil proof (P-series) must be evaluated using an oil-based aerosol. * Only N-series filters are evaluated using a NaCl aerosol, which is slightly degrading to filter medium. There are three categories for NIOSH-certified, nonpowered, air-purifying, particulate-filter respirators: N (Not resistant to oil), R (Resistant to oil), and P (oil Proof). Respirators for NIOSH pre-submission are required to be preconditioned at 85 ± 5% RH and 38 ± 2.5☌ for 25 hours prior to assessing the filtration efficiency. The amount of NaCl that passes through the sample is used to calculate the filtration efficiency of the sample. The concentration of NaCl is measured before and after impact with the sample. Samples are subjected to aerosolized NaCl. Cone or molded masks and respirators are mounted to a test fixture and sealed into a cylinder filter holder to ensure that the mask is properly sealed. In this procedure, the TSI® CERTITEST® Model 8130 Automated Filter Tester reservoir is filled with a 2% NaCl solution.* The sample is placed into the filter holder. The Sodium Chloride Aerosol Challenge test is able to determine filtration efficiency measurements up to 99.999%. Study Outline Sodium Chloride Aerosol Challenge TEB-APR-STP-0057-0058-0059ĭownload our respirator testing requirements PDF to assist you in determining which test is required for your location. Nelson Labs has extensive experience testing filters and other filtration devices. RC-APR-STP-0057, 00 is necessary prior to submission for NIOSH certification of respirators. Testing is performed in compliance with 42 CFR Part 84 and NIOSH Procedure No. The Dioctyl Phthalate (DOP) test is used to evaluate particle penetration and airflow resistance properties for a variety of filtration materials, including HEPA filters, NIOSH respirators, and filter media. are tested to determine filtration efficiency for marketing purposes. Other materials, such as breathing system filters, face masks, etc. The Sodium Chloride Aerosol Challenge (NaCl) uses a widely accepted method for evaluating particle penetration and airflow resistance properties of a variety of filtration materials. Nelson Labs offers these pre-submission testing services. These tests can be performed by the manufacturer or a third-party laboratory and must follow NIOSH Standard Testing Procedures (STPs) and use appropriate instrumentation. Respirators intended for submission to NIOSH may require NaCl, DOP, valve leak, and inhalation/exhalation tests to verify that the respirator meets the minimum performance requirements.
