Protection against particulates and toxic gases.
The half-mask must be used when the toxic concentration allows it.
The limit is determined by a theoretical calculation taking into account the air leakage around the face and the filter efficiency.
The half-mask, depending on the filter used, must be used for concentrations between 12 x TLV and 50 x TLV.
(TLV= TWA for 8 hours of work or STEL for 15 minutes of work )
(For more detailed information, refer to the INRS document ed. 780 “Respiratory protection devices”).
A half-mask must be used with class 1 (for gases) and P2 or P3 (for particulates) certified filters.
Sperian Plus is certified to EN 140:1990 standard and provides the following Nominal Protection Factors and Assigned Protection Factors :
For gases and vapours : NPF = 50 - APF 10*
For particulates with P3 : NPF = 50 - APF = 20
For gases with P3 : NPF = 50 - APF = 10*
*For Class 1 gas filters : 10 or up to 1000 ppm (whichever is the lowest)
*For Class 2 gas filters : 10 or up to 5000 ppm (whichever is the lowest).
They can only be used in sufficiently ventilated premises where the atmosphere contains a minimum oxygen volume of 17 %.
