Because they create positive pressure, they need not be tightly fitted. [26] PAPRs typically do not filter exhaust from the wearer. [27] Shortcomings [ edit ]

The supplied air respirators - with positive pressure demand air supply to the masks; and with continuous flow air supply to the helmets or hoods. Measurement of workplace protection factors surprisingly revealed the low efficiency of some designs of respirators, and that results have led to a sharp tightening of the requirements for application limits for respirators of such designs.US law obliges the employer to accurately measure air pollution at workplaces. The results of such measurements are used to assess whether short-term inhalation of harmful substances may lead to irreversible and significant deterioration of health, or death ( IDLH concentrations). If concentrations exceed the IDLH, the standard allows the use of only the most reliable respirators - SAR or self-contained breathing apparatus: with pressure-demand air supply in the full facepiece mask ( §(d)(2) [22]).

The study [26] showed that the three models of full face masks had a significant leakage of unfiltered air through the gaps between the mask and the face. The minimum values of the workplace protection factors (WPF) of each of the three negative pressure full face mask models were 11, 17 and 26. The maximum value of the WPF from one of the models did not exceed 500 no times at all. And for all results together, the WPF was not more than 100 in ~ 30% of the measurements. So, for this reason, the values of the APFs for this RPD type in Germany (400), Finland (500), Italy (400), and Sweden (500), may not fully take into account the lower this type respirators' performance at the workplace compared to the performance in the laboratory (during certification). The same was true for other RPD types and their APF. The Ukrainian version of the EU standard EN 529 does not set any values of the APFs for the selection of respirator in this country. [30] This document only listed the values of APFs in several European countries (for reference); and declares the inadmissibility of the use of laboratory efficiency for predicting the protective properties at the workplace.

n100 mask is a great choice for those who want the high-rated by NIOSH filter efficiency in their respirator. This mask is approved for lead abatement, metal fumes from welding, radioactive particulate materials, and non-oil containing mists. The 3M ™ Particulate Respirator 8293, P100 with Cool Flow ™ Valve is a lightweight, disposable P100 particulate respirator is well suited for those who want NIOSH's highest rated filtration efficiency. It provides a minimum filter efficiency of 99.97% against oil and non oil based particles. 3M uses a variety of innovative technologies and features to help you meet your respiratory protection and comfort needs.

Closing Thoughts

Fit testing of tight-fitting masks of negative-pressure respirators became widely used in US industry in 1980-s. At the beginning, it was thought that the half-mask fit quite well to the worker's face, if during a fit test the protection factor (fit factor) is not less than 10 (later, experts began to use "safety factor" = 10 during the fit test; threshold fit factor become 10 × 10 = 100). The widespread use of fit testing in the industry gives professionals optimism, and they allowed to the employers restrict the use of half mask respirators in accordance with the values of worker's personal fit factor (the maximum concentration of pollutants = personal Fit Factor × PEL), but not more than 100 × PEL. However, scientific studies have shown that although such test increases the effectiveness of protection, the risk of leakage of large amounts of unfiltered air is maintained. Furthermore, the studies have shown that non-filtered air under the mask is not uniformly mixed with the filtered air, which leads to large errors in the measurement of the in-facepiece concentration of contaminants, and subsequent calculations of fit factors - the latter is often much smaller than the "measured" value. So, specialists recommend not allowed usage negative pressure half mask respirators then harmful substances' concentrations exceeds 10 PEL. [28] Therefore, OSHA standards require to restrict using of half-mask negative-pressure respirators up to 10 PEL after obtaining fit factor greater than or equal to 100 during the mask selection for the worker (they used a safety factor = 10). Example of measurement of efficiency of the respirator (in the workplace). Description: (1) personal sampling pump, (2) the cassette and the filter for determining the concentration (in the breathing zone), (3) the sampling line (from the breathing zone), (4) the cassette and the filter to determine the concentration (under a mask), and (5) the sampling line (from the mask).
