Workplace PF of filtering facepiece, measured in real time with two optical dust meters. In-facepiece dust concentration is changed dozens of times in a matter of minutes due to changes of the size of the gaps between the mask and face. Source [9] State standard in India [29] points to the need to use the workplace protection factors for restricting the permissible use of respirators, but does not set any values of the APFs. The standard also recommends the use of those PFs, which are obtained during the certification (in the laboratories, but not at workplaces). These values greatly exceed the values used in the USA and in the UK. HE (high-efficiency) labeled filters are only provided for powered air-purifying respirators. These HE-marked filters are 99.97% efficient against 0.3 micron particles and are oil-proof, and therefore their filter-media material has the exact same specification as a P100 filter. [6] [7] [8]

Summary

The experts used the results of measurements at the laboratories and at the workplaces to develop more completely terminology for description of the respirators' performance; [13] [14] [15] [16] and this terminology has been applied officially, [17] and in the preparation of research results for publication. [18] Specialists began to use different terms to describe the protection factors, which were measured at workplaces with continuous use of respirators; and measured in the workplace when the workers used of respirators intermittently; measured not in the workplace while fit testing; measured in the laboratories under the simulation workplace's conditions; and for the protection factors, that can be expected ( in most cases) when the workers properly used the respirators at the workplace.

Additionally, HE (high-efficiency) filters are the class of particulate filter used with powered air-purifying respirators. These are 99.97% efficient against 0.3 micron particles, the same as a P100 filter. [35] [36] [37] N for not resistant to oil. Used when oil particulates are not present. Tested using sodium chloride particles. Achieving a mask with higher capacity, optimal comfort, as well as high efficiency in eliminating bio-aerosols and optimal filtration of airborne particles has always been one of the goals of studies conducted in this field [ 7]. For this purpose, the factors affecting the determination of the final mask quality have been focused on increasing and improving the efficiency of the mask in the center of attention. In general, the filtering ability of the mask is influenced by the specifications of the mask filter and external factors [ 8, 9].Roberge, Raymond J.; Coca, Aitor; Williams, W.

A measure of the protection provided in the workplace only while the respirator was properly worn and used during normal work activities (WPF are measured at the workplaces, after fit testing; and without mask doffing during measurement).

Mass production of filtering facepieces started in 1956. The air was purified with nonwoven filtering material consisting of polymeric fibers carrying a strong electrostatic charge. Respirator was used in nuclear industry, and then in other branches of economy. For ~60 years, more than 6 billion respirators were manufactured. [24] Unfortunately, the developers overestimated the efficiency ( APF 200-1000 compared to the modern value of 10–20), which led to serious errors in the choice of personal protective equipment by employers. In some cases, there was no information on the effectiveness for respirators of specific design (type) in the workplace. This is due to the fact that the measurement of workplace PF is very difficult, time consuming, and expensive work, which was carried out not very often. For these types of respirators experts used the results of WPF measurements of other types of respirators, which are similar. For example, the effectiveness of the Supplied Air Respirators (SARs, with hose) was considered similar to the efficiency of Powered Air Purifying Respirators (PAPRs), if they have the same facepieces and the same air supply mode. Finally, in the absence of this information, specialists could use the results of Simulated WPF measurements; or estimates of competent experts. [20] Correction of Assigned PF values [ edit ]

The difference of the APF for air purifying negative pressure full-facepiece masks are not large. The difference between PAPR with helmets a few more. But measurements showed that the real effectiveness of RPD (at the workplace conditions) is strongly dependent on the conditions of their use, not only from the design, and this partly explains the difference in APF values. The APF for negative pressure half mask respirators are twofold. But this difference cannot be considered separately from recommendations for use of respirators. The use of half-face masks in the US is limited to 10 PEL for the "worst case" - work in the polluted atmosphere of 8 hours per day, 40 hours a week. But British experts took into account large experience of the use of negative pressure air purifying RPDs, and they concluded that to achieve continuous wear respirator 8 hours a day is impossible (because of the negative impact on the health of workers). For this reason, they recommend to the employer to give the job to the workers so that they work in the polluted atmosphere not during entire shift, but only a part of the shift. The remaining time the employee needs to work in a non-polluted atmosphere (without the respirator). The fact that the employee is in a non-polluted atmosphere some part of working time provide additional protection of his health, and therefore, the requirements to the efficiency of the respirator may be less stringent. The NPPTL has also published a guideline for using non-NIOSH masks instead of the N95 in the COVID-19 response. The OSHA has a similar document. The following respirator standards are considered similar to N95 in the US: [72] [73] Critical Issues Conference On In-Facepiece Sampling".
