Full-face mask respirator

Description

  • This type relies on the wearer's breathing to pull the air through the filter
  • Full face masks cover the whole area of the face. Some makes are fitted with an inner half mask
  • They are supplied in different shapes and sizes
  • In general, respirators are made from flexible rubber or silicone material
  • They can be cleaned and used many times, as recommended by the manufacturer
  • A full-face mask can be fitted with particle filters, gas filters, vapour filters or a combination of gas, vapour and particle filters
  • These masks have inlet and outlet valves which must be in good condition

  • These respirators are adequate for light work (working work activity when seated) and medium work rate (work activity involving sustained hand and arm movements, or similar to brisk walking)
