Respirator Maintenance and Protection

Respirators are only useful when there is a combined knowledge of purpose, maintenance, fitting, testing, and their relationship to various fibre concentrations.

If the user is not clean shaven, wearing a respirator will provide little or no protection due to the air movement around and under the sealing surface of the mask.

Respirators come in 3 sizes: small, medium, and large. When selecting a respirator, make sure it’s the right size, it fits properly and feels comfortable, this is mainly done by adjusting the head and neck straps.

The selection, maintenance, testing, and quality of supplied air must comply with appropriate State or Territory Regulatory requirements.

Checking Inhalation Valves

These valves are located on the sides of the face mask and consist of a light rubber material. These diaphragm valves are held in place over their openings by small plastic studs. Check to see if they are in good condition and operate freely.

Checking Exhalation Valve

This valve is located in the bottom of the face mask. Remove the exhalation valve protector and check the valve for wear, deterioration, distortion and for particles that could restrict the operation of the valve. This can be done by gently rotating the valve with your fingers.

This valve should be checked every time you put on your respirator. Your health and safety depend on this valve working correctly. If the valve sticks open all you air will come through the opening instead of through the filters and you might as well not even have the respirator on.

Checking Filter Holders

The two large discs on the side of the face mask are called the filter holders. Inside the filter holders there is a rubber gasket that must be laying perfectly flat around the inside edge of the holder. Check to see that this gasket is not crimped or damaged and that it is seated correctly to ensure a good seal with the filter cartridge.

Checking Face Mask and Straps

Check around the sealing area of the mask for cuts, cracks or excessive wear that could possibly prevent a good seal. Check straps accordingly to ensure they are in good shape.

Checking Fit Testing of Respirators
After checking the respirator’s parts, sealing edges and straps, a fit test must be performed to ensure maximum protection is provided to the user.
