Respiratory Guide

Which Respirator should you use?

There are four simple principles of respiratory protection:

• Always select the right respirator for the task e.g. correct filters
• Always ensure a proper face fit. Fit test if necessary.
• Have an active maintenance program to support the devices in use, including cleaning and defect recognition.
• Ensure proper storage of equipment. Best kept in an airtight container.

Contaminant

There are several  factors which need to be considered when selecting a suitable respirator for a particular situation.

These factors are:

• The nature, toxicity, physical form and concentration of the contaminant.
• Always ensure a proper face fit. Fit test if necessary.
• Have an active maintenance program to support the devices in use, including cleaning and defect recognition.
• The adequacy of the warning given by the contaminant, e.g. odour threshold.
• The possibility of the contaminated atmosphere being flammable.

Task

• Whether the device is for regular use or for emergency or rescue purposes.
• The probable length of time during which the wearer will be in the contaminated atmosphere.
• The expected level of activity and mobility required by the wearer.
• Whether the access and location air source is suitable for breathing.
• The need for clear vision and communication.
• The facilities available to maintain the device.

Operator

• The effect of the general environment on the operator.
• The importance of facial fit (the presence of facial hair will adversely affect the fit).
• The expected level of activity and mobility required by the wearer.
• The comfort afforded by the respirator over extended periods of use.

If you have any doubts as to the correct device for a particular situation, you should seek expert advice.
