ASTM Level, 1 Surgical ,Mask ASTM Level, 1 ,Masks, are the standard for surgical ,masks,. As part of the complete Cardinal Health facial protection offering, they are a cost-effective solution for general use, particularly in low-fluid cases.
A higher ,level, of respiratory protection is afforded by ,ASTM Level, 2 ,masks,. These are manufactured to provide a protective barrier when treatment produces moderate amounts of airborne fluid, spatter and/or aerosols. Examples of ,mask, use here would include most routine restorative procedures and when performing scaling and root planing.
Only ,Level, 4 gowns are tested for viral penetration resistance, and therefore only ,Level, 4 garments are considered impermeable to viral penetration using ,ASTM, F1671. The gowns complying with the lower ,levels, (,Level, 1, 2, and 3) cannot be considered impermeable. However, ,Level, 1–3 gowns can provide increasing resistance to liquids.
Procedure ,masks, protect both the patient and health-care provider from transferring respiratory secretions, bodily fluids, or other potentially infectious material. Procedure ,masks, have ear loops rather than ties. ,ASTM, performance metrics and ,levels, 3
Cardona recommends using the following ,charts, to determine the most appropriate ,mask, rating ,levels, for different procedures: UE 3 2019 DentalGroupPractice.com 35 ,ASTM, International is an inter- ... ,ASTM Level, 1 ,ASTM Level, 2 ,ASTM Level, 3 Ideal for procedures where low amounts of fluid, spray and/or aero-sols are produced.
Of course, the ,mask, passed all 3 tests will be the best. 2. ,ASTM Level,. Most ,masks, manufactured in the United States will follow this test standard. The protective strength of ,masks, is divided into ,Level, 1 to 3, with ,Level, 1 being the lowest and ,Level, 3 being the highest, whiile BFE and PFE are also tested.
Medical face ,mask, materials are designated as one or more of the following performance classes: ,Level, 1 barrier, ,Level, 2 barrier, and ,Level, 3 barrier. The barrier performance classes of medical face ,mask, materials are based on bacterial filtration efficiency, differential pressure, sub-micron particulate filtration efficiency, resistance to penetration by synthetic blood, and flammability.
ASTM Level, 3 ,Masks, are recommended for use in areas with procedures in which moderate to high amounts of fluid, spray and/or aerosols are produced, such as complex oral surgery, crown preparation, implant placement, periodontal surgery, and more.
IMPORTANT: The filtration efficiency and protective ability of a face ,mask, is compromised when the ,mask, becomes wet, torn or dislodged. In general, the higher protection value of a ,mask, the longer it will maintain filtration; however, there is no set rule for how long a ,mask, should be worn as it depends on humidity ,levels,, respiration rate, nasal discharge, talking, etc.
