English

Subject field(s)
  • Protection of Life
  • Occupational Health and Safety
CONT

... the formaldehyde levels in the space ... exceed the threshold limits. ... employees were advised to wear half-shields to protect themselves; while some employees use respirators she finds this practice questionable.

OBS

An "oronasal mask" (see this other record in TERMIUM) is a good example of this type of respirator.

OBS

Although "facepiece" is a component part of a respirator, it is often used to designate the whole respirator. "Respirator" is a generic term compared to "mask", but most of the time it designates a mask, as in this case.

OBS

Air-purifying respirators can have quarter, half, or full facepieces. The choice among these alternatives depends on ... the nature of the hazard and comfort. If exposure to the hazardous substance causes skin or eye irritation, then a full facepiece will be necessary.
