National Institute for Occupational Safety and Health The National Institute for Occupational Safety and Health of the United States is an internationally renowned and important occupational safety and health research institution. It mainly conducts scientific research on occupational safety and health and makes recommendations on the prevention of work-related injuries and diseases. The institute is part of the Centers for Disease Control and Prevention within the U.S. Department of Health and Human Services.
What is NIOSH certification?
NIOSH is part of the U.S. Centers for Disease Control and Prevention within the U.S. Department of Health and Human Services. Its mission is to ensure "safe and healthful working conditions for every man and woman in the Nation and to protect our human resources." NIOSH has more than 1,300 employees in a variety of fields, including epidemiology, medicine, nursing, industrial hygiene, safety, psychology, chemistry, statistics, economics, and many branches of engineering.
What is the review process for NIOSH certification?
It must be implemented in accordance with NIOSH guidelines. Enterprises must send samples to NIOSH laboratories for testing and submit technical information (including quality system information) to NIOSH for review. Only after both the review and the test are passed, will NIOSH issue the approval.
NIOSH divides its certified anti-particle masks into 9 categories, and the specific tests are carried out by the NPPTL (National Personal Protective Technology Laboratory) under NIOSH. The main test indicators include exhalation resistance test, exhalation valve leakage test, inhalation resistance test and filtration efficiency test.
The relationship between NIOSH certification and N95 masks:
The N95 mask is one of the nine types of particle-proof masks certified by NIOSH (National Institute for Occupational Safety and Health). "N" means it is not suitable for oily particles (the fumes produced by cooking are oily particles, while the droplets produced by people talking or coughing are not oily); "95" means that under the testing conditions specified by NIOSH standards, the filtration efficiency reaches 95%. N95 is not a specific product name. As long as the product meets the N95 standard and passes the NIOSH review, it can be called an "N95 mask."
