“ Measurements of the coefficients of the protection of respirators in the workplace showed that the effectiveness of respirators may be significantly reduced due to the leakage of unfiltered air under the mask through the gaps between it and the face. Gaps can occur because of insufficient proper selection and use of masks and mask slipping during operation. ”

“ The risk of significant and unpredictable reduce the protective properties of common negative pressure respirators prompted to prohibit the use of such respirators (without constant positive pressure under the mask) when levels of air pollutio is, immediately dangerous to life and health IDLH (when short-term exposure can lead to acute poisoning, irreversible damage to the health and/or prevent evacuation, for example - because of the impact on the eye) . The values of these concentrations in the RF is not installed, and it hurt to use the conventional methods of selection of respirators. ”

“ In the workplace, in those cases where it is impossible to apply the technological, technical and sanitary preventive measures (or their low efficiency) [59] for the protection of workers from harmful substances in workplace air in concentrations exceeding the PEL, use RPE. To adequately protect people working in hazardous conditions, requires information on the effectiveness of respiratory protective equipment of various types (designs) . ”
