The N95 respirator mask was developed by 3M and approved in 1972. [114] Due to its ability to filter viral particulates, its use was recommended during the COVID-19 pandemic but supply soon became short. [ 114 ]
An N95 respirator is a disposable filtering facepiece respirator or reusable elastomeric respirator filter that meets the U.S. National Institute for Occupational Safety and Health (NIOSH) N95 standard of air filtration, filtering at least 95% of airborne particles that have a mass median aerodynamic diameter of 0.3 micrometers under 42 CFR 84, effective July 10, 1995.
On this scale, 1 is a completely ineffective respirator. Some respirator manufacturers, like 3M, complained that DM and DFM respirators with superior filtration, that would normally receive an APF well above 2, were being "held hostage" by poorly-performing respirators. [97]
Workers are instructed to put their mask on and leave immediately to sound the alarm if they detect a leak. Other respirators may be used for making repairs to leaking equipment. [51] Elastomeric respirators may be worn in agriculture, [5]: fig.2–4 for instance when using agricultural chemicals, solvents, fish meal, silage, mold spores and dust.
At high altitude, from 1,500 to 3,500 metres (4,900 to 11,500 ft) there are physiological effects of the reduced oxygen partial pressure which include reduced exercise performance and increased respiratory rate. Arterial oxygen saturation is generally still over 90% in healthy people, but arterial P O 2 is reduced. [2]
On April 2, Trump announced that he would invoke the Defense Production Act to compel 3M, General Electric, and Medtronic to increase their production of N95 respirators. [146] [147] By September 2020, N95 respirators were still in short supply. Even though 3M had increased domestic production from 20 million to 95 million respirators a month ...
