Nanoparticles are one of the main emerging industrial risks.
Nanoparticles are generally identified as particles made of atomic or molecular aggregates with a diameter of approximately 1 to 100 nm. Sometimes the term is used to denote ultrafine particles (in particular the individual particles that make up nanopowders).
The use of nanoparticles in consumer goods is showing benefits and attracting
investment, but it is also raising concerns because, under certain conditions, exposure
to nanoparticles, being too small for our body's natural defences, can have negative effects on our health and on the environment.
The EPI4Nano project, promoted by BLS and carried out over the two-years period 2021/2022 by the Itene Research Institute, based in Valencia (ES), had its
main purpose in the development, optimisation and validation of specific BLS
products for effective respiratory protection against nanoparticles, including carbon
nanofibres and metal oxides.
Studies have shown that some nanoparticles can penetrate cells and tissues, move through the body and brain, and cause biochemical damage. In particular, the small size of nanopowders allows them to behave in a way that can be described as intermediate between that of gases and the rest of suspended particulate matter.
For this reason, when one comes into contact with these materials or performs work that may cause their dispersion into the air, the use of appropriate respiratory protective equipment is essential.
BLS products certified for protection against nanoparticles include:

With a filtering capacity of more than 94% for FFP2 and more than 99% for FFP3, the new BLS 502 and BLS 503 masks are DPI without valves, CE certified according to European regulation 2016/425 and technical standard EN 149: 2001, able to protect users in the event of exposure to solid and/or liquid non-volatile particles (dust, fumes, mists) and to block the dispersion of viruses both incoming and outgoing. They are, in fact, sealed on the face and manufactured with a "welding” process, without seams and perforations on the fabric from which micro particles could pass, thus creating a barrier during exhaling, protecting the environment from the user of the mask. These masks are therefore ideal for use in the food & beverage and medical sectors, as well as in all work environments where contamination by the user must be avoided.
