With the development of the global epidemic, everyone is paying close attention. Enterprises or individuals frequently ask if there are medical-grade masks and other protective supplies available. However, except for frontline medical personnel, most people do not actually need medical-grade protective equipment. This mindset only adds fuel to the fire for already scarce protective supplies. Therefore, Hehu Safety is here to provide some knowledge popularization:

1. Medical Protective Masks: Comply with the Chinese GB 19083-2010 mandatory standard, with a filtration efficiency ≥95% (tested using non-oily particulate matter). Requires passing the synthetic blood penetration test (to prevent fluid splashes) and meeting microbiological indicators.

2. N95 Masks: NIOSH certified in the USA, with a non-oily particulate filtration efficiency ≥95%.

3. KN95 Masks: Comply with the Chinese GB 2626 mandatory standard, with a non-oily particulate filtration efficiency ≥95%.

The test methods for filtration efficiency for the above three types of masks are exactly the same! Therefore, the filtration efficiency levels are consistent.

Medical masks have the added synthetic blood penetration test. Therefore, buying NIOSH N95 and GB2626-2006 KN95 masks is the same for everyone. The key to wearing a mask lies in the seal with the face; please see the wearing instructions below:

Particulate Filtration Efficiency:

Microorganisms are non-oily particulates, so N-series masks should be used for protection.

Let's take a look at the needs of frontline hospitals in Wuhan:

Everyone, think about it: is there a risk of blood penetration for the needs of general enterprises and individuals?Is there a need for sterility (which pharmaceutical companies might have)?It is truly inappropriate for our over-protection to cause a lack of protection for frontline medical staff.

Of course, those not working in this industry would not know the difference; it is instinctive to want higher protection. This is when we professionals need to disseminate correct information.Happily, many of my professional EHS friends have already taken action, using their professional background to filter out misinformation. Salutes to you all!

Safety enterprises connecting manufacturers with end-users and refraining from price gouging—this is corporate responsibility!

Industry professionals and safety personnel conveying correct information and guiding public opinion correctly—this is our responsibility!
