Paint spraying operations often use more than one type of respiratory protective equipment (RPE), with the right kit depending on the coating, the substances released during application, the level and duration of exposure, and the ventilation available in the spraying area.
For example, when your employees spray isocyanate-containing two-pack coatings, the HSE requires air-fed breathing apparatus with an assigned protection factor of at least 20 and an integrated low-flow warning. In these cases, standard filtering respirators cannot provide suitable protection against the high concentrations of invisible isocyanate mist created inside the booth or room.
Surface preparation work creates a separate hazard profile – e.g. sanding may produce fine particulate exposure, while mixing and cleaning can expose workers to solvent vapours. For these applications, a P3 filter is designed to capture hazardous particles, such as paint mist or dust, but it does not remove solvent vapours. Your filter selection must therefore reflect the coating being applied, the way it is used and the specific respirable hazards, gases or vapours identified in the product safety information.
