• People who work with harmful dusts should not use nuisance masks.  They may also be called comfort masks or hygiene masks
  • Nuisance dust masks are not protective devices – they perform badly and do not meet basic health and safety requirements.
  • Nuisance dust masks are not classified as PPE and so are not CE marked.
  • They should not be used for protection against fine dusts, welding fumes, fine sand, paint spray, gases, vapours or aerosols.  They are also unsuitable for protection against grain and flour dust, hard or softwood dust, fumes from rosin- based solder flux or any substances with a maximum exposure limit.
  • They should only be used when dusts are not hazardous to health.
  • They may consist of a thin metal plate that holds a piece of gauze over the nose and mouth or a lightweight filter that looks similar to a disposable dust respirator.  They often have only one head strap.
