The recommendation will depend on the type of welding, the working environment, whether any ventilation is in place etc. Please contact our Sales Team on firstname.lastname@example.org or telephone +44 (0)161 877 4747.
Alpha Solway have developed a Qualitative Face Fit Test Kit. For more information please refer to our Face Fit Test Kit section.
Simply, an FFP3 will offer greater protection than FFP2 and FFP1. An FFP1 has an Assigned Protection Factor (APF) of 4, FFP2 has an APF of 10 and an FFP3 has an APF of 20.
Selection of the most appropriate respirator depends on the contaminant and Occupational Exposure Level (OEL) and guidance should always be sought. You can use our Respirator Selector Guide for initial guidance but please contact us direct for more specific information.
All disposable respirators and half masks fitted with particulate filters can be tested. Please contact us on 01461 202452 for more information.
The valve helps lower the temperature inside the mask and also reduces condensation caused by the mask on wearers’ spectacles.
A disposable respirator will last for a maximum eight-hour shift or until the wearer finds the breathing resistance is too great.
The current standard is EN149:2001+A1:2009, although respirators are still legally in the marketplace under the previous EN149:2001 standard.
Simply, the new standard combines solid and liquid test methods for each respirator, but precisely:
Under the old EN149 standard the classifications were FFP1S, FFP2S, FFP2SL, FFP3S and FFP3SL. These have now been superseded by just FFP1, FFP2 and FFP3.
Previously, whilst the old ‘S’ type respirator protected only against solid and non-volatile liquid particles, the ‘SL’ type had also to protect against oil based mists. This could potentially lead users to select by mistake an ‘S’ model instead of the correct ‘SL’ model when one or more of the hazards was an oil based mist.
Today with the new standard in place all models conforming to EN149:2001 must offer protection against all of the hazards mentioned previously, which can only decrease the risk to the health and safety of the end user.
