Supplied Air Respirator Standards

Supplied-Air Respirators (SARs) - The basic SAR is comprised of a respirator facepiece—which could be a tight fitting half mask or full face mask or a loose-fitting hood or helmet assembly—connected via an air supply hose to a source of breathing air The air supply could be either a low pressure or high pressure source A low pressure source would be an ambient pump (an air compressor

International Regulatory Standards and Comparisons for N95

International Regulatory Standards and Comparisons for N95 Respirators Summary Due to the shortage of N95 respirators in the U S during the COVID-19 pandemic hospitals and healthcare workers are looking to international suppliers to supplement crucial personal protective equipment (PPE) Similar respirators to the gold standard N95 are available for import from many countries under

COVID

Equivalent respirators approved under standards used in other countries are also acceptable such as medical KN95 respirators and FFP2 respirators if the manufacturer can provide the evidence demonstrating testing to the appropriate standards The N95 respirator is the U S /NIOSH standard for respirators and KN95 is the Chinese standard Commercial-grade (non-medical) and medical-grade

Safety and Health Topics

The respiratory protection standards for the shipyard employment (29 CFR 1915 154) marine terminals (29 CFR 1917 92) longshoring (29 CFR 1918 102) and construction industries (29 CFR 1926 103) reference the respiratory protection standard for general industry (29 CFR 1910 134)

Comparison of Mask Standards Ratings and Filtration

Surgical mask standards have higher requirements for capturing virus-sized (0 1 micron) particles however they vary by region Pollution masks (respirators) typically capture 90% of virus-sized particles You can use the rating system in the table above to see the exact proportion each certification requires This includes ratings such as N95

Respiratory protective equipment (RPE)

Respirators come in different shapes and sizes One size will not fit everyone It is important that a fit-test is carried out for each person who will wear a respirator Surgical or patient care masks and nuisance dust masks do not protect the wearer from airborne contaminants such as small particles aerosols gases or vapours These masks protects the wearer from splashes of large droplets
