Respiratory Protection

Between May and November 2020, the National Institute for Occupational Safety and Health (NIOSH) issued limited, temporary Public Health Emergency (PHE) approvals for N95 filtering facepiece respirators (FFRs) and powered air-purifying respirators (PAPRs) to address respirator supply shortages during that time. In July 2021, NIOSH published NIOSH CA 2021-1036 to remind PHE approval holders that these…...

HSE Inspectors routinely come across workers with various degrees of stubble growth using respiratory protective masks despite guidance to the contrary. This research studied the effect of 0-7 days stubble growth on the protection given by FFP3 filtering facepieces and half masks.  Fifteen male volunteers took part, each testing four masks. For most, three different…...

At 5:00 p.m. on February 4, 2021, an employee was working for a firm that manufactured fabricated structural metal. He was performing abrasive blasting with steel shot. He was wearing a supplied air respirator (SAR). While using the supplied air hood, he lost consciousness. A pressure testing operation downstream on the plant airline allowed nitrogen…...

At 12:00 noon on August 19, 2021, an employee utilized an airline respirator that was attached to a nitrogen line. The employee died from a lack of oxygen…. Membership Required You must be a member to access this content.View Membership LevelsAlready a member? Log in here...

I have been validated!  I have received so many nasty grams from folks regarding my position on the ASSUMED PAPR Assigned Protection Factor of 1,000 which I wrote about in several postings going all the way back to 2015 of which this was my first attempt to educate and warn others of some flawed practices:…...

Generally, you asked OSHA to clarify whether loose-fitting powered air-purifying respirators (PAPRs) are a permissible alternative to N95 respirators where respiratory protection is required to protect workers from exposure to SARS-CoV-2, the virus that causes COVID-19. Additionally, you asked OSHA to clarify the interplay between the Respiratory Protection Standard and other laws that may require…...

OSHA titled the standard, “Mini Respiratory Protection Program“, but when we read it we see that it could very easily be applied to “voluntary use” NOT associated with COVID 19. So I ask, could this “emergency standard” become permanent and have 1910.134(c)(2) refer to this “standard”? OSHA has made it VERY clear that at this…...

NIOSH is recommending a new standard in face masks for workplaces, called Workplace Performance and Workplace Performance Plus masks Manufacturing masks that comply with the new NIOSH criteria can help protect people in the workplace from SARS-CoV-2, the virus that causes COVID-19. These masks CANNOT be used as a replacement for respiratory protection when it…...

Last week I mentioned a trade group was planning to implement a standard/guide (not sure how it will be classified) that will suggest that the industry should use respirators that carry a NIOSH 14G approval rather than the more common 23C respirator.  Since all of this has been happening I have received numerous e-mails, calls,…...

I just finished reviewing a draft document that a trade group will be asked to vote to sanction the document as it relates to emergency escape respirators.  There was a lot of talk about requiring these escape respirators to carry the NIOSH approval of 14G (vs. the more traditional 23C style respirator).  There is talk…...

Many of us manage a Respiratory Protection Program for all types of respirators and many types of hazards.  What many programs lack is the annual evaluation of the program and its execution. The written program should contain information on how and who will perform this evaluation and although the standard does not state this evaluation…...
