152 EN149:2001+A1:2009 Respiratory protective devices — filtering half-masks for protection against particles All uvex respirators are tested and approved in accordance with the European standard 149. This standard sets out a wide range of requirements for respirators, with the aim of providing the user with the highest level of protection and comfort. In addition to the standard tests, all uvex masks fulfil the additional requirement of the dolomite dust test and are therefore marked with the letter D. Therefore the uvex respiratory protection products ensure an excellent breathability, even in extremely dusty environments and during prolonged use. All uvex respirators are in line with current EU legislation. All respiratory protective devices fall into PPE category III (high risks). The standard divides respirators into three protection classes according to their filtering efficiency and leakage: The key tests defined in EN149 are: • measuring inhalation and exhalation resistance • testing the exhalation valve • visual inspection (marking, instructions for use) • determining the filtering efficiency (protection class) • optional: carrying out the dolomite dust test Detailed information about the standards and guidelines for respiratory protection is available at: https://ures.uvex.de So that you can see the protection class at a glance, the marking is blue on FFP1 masks, orange on FFP2 masks and black on FFP3 masks. FFP 1 FFP 2 FFP 3 * OELs = The occupational exposure limit values (OELs) are the average concentration of a substance in the air in the workplace, up to which no damage (chronic or acute) is to be expected if employees work there for eight hours a day for five days a week. The OELs replace the maximum workplace concentration (MWC) and the technical reference concentration (TRC) – however, as long as both of these values are not yet fully taken into account in the OELs, they can still be used on an interim basis for assessing risks in the workplace. FFP1 respirators have a filtering capacity of at least 80% and filter up to four times the respective occupational exposure limit (OEL*). These masks are suitable for particles that are neither toxic nor fibrogenic. FFP2 respirators are suitable for smoke, particles and dusts that are noxious or harmful to health. They filter at least 94% of particles and can be used up to ten times the respective occupational exposure limit (OEL*). With a filtering efficiency of at least 99%, FFP3 masks constitute the highest protection class. They filter up to 30 times the respective occupational exposure limit (OEL*) and are suitable for protecting against toxic particles, dusts and smoke.
