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:
Sai indossare correttamente un DPI? Indossare un DPI nel modo corretto è fondamentale per trarne massima efficacia e migliori performance di prodotto. Lo scopo della protezione respiratoria individuale è proteggere chi la indossa da sostanze tossiche o patogene diffuse per via aerea. Il suo utilizzo, quindi, dovrebbe essere preceduto da una formazione appropriata sulle […]
