Chp3 Respiratory Protective Equipment Flashcards
What is Respiratory Protective Equipment (RPE)?
RPE is worn to protect staff from respiratory hazards such as dust, mists, metal fumes, gases, and vapours.
What are the two classifications of RPE?
-Filtration and
-Breathing Apparatus.
What is Filtration in RPE?
Filtration may be passive respirators or powered respirators.
What are passive respirators?
Passive respirators rely on lung function to draw air through the filter and fit tight to the face.
What are powered respirators?
Powered respirators pump air through a filter supplied at positive pressure to prevent contaminated air from leaking in.
What is Breathing Apparatus in RPE?
Breathing Apparatus provides the wearer with a supply of breathable air from an independent source (airline or self-contained).
What are the most common types of RPE in aircraft maintenance?
The most common types are those worn over the face or head, such as hoods or masks, and filters attached directly or via a pump.
What is Loose Fitting RPE?
Loose Fitting RPE can be a hood (including air fed) or visor. No fit testing is required for this type.
What is Tight Fitting RPE?
Tight Fitting RPE can be a half mask or full face, and requires a fit test at initial selection.
What are personnel responsibilities regarding RPE?
All personnel must complete a self-assessment, which is recorded and held on file.
When is a repeat fit test required?
A repeat fit test is required if there are significant physical changes to the individual’s head that may affect the seal of the RPE.
What should a wearer check before using RPE?
The wearer must ensure that the face piece seals correctly before use.
What should be done if defects are suspected in RPE?
Any suspected or known defects must be reported to the supervisor.
