INSTRUCTIONS FOR USE
Unpacking instructions
•
Carefully remove the mask from the packaging.
•
Check that the equipment is complete and free of damage. Contact your supplier immediately if any item is damaged or missing. The
mask must not be used if it is damaged or incomplete.
Storage
•
Do not store at temperatures below -20°C or above +50°C or in an atmosphere with relative humidity above 90%.
•
Store the mask away from sunlight and dust in its original packaging or in a sealed container.
Checks before use

Read the user instructions for the equipment connected to the mask.

Check that the mask is not damaged in any way.
Donning the face mask
1. Place chin into bottom of mask and pull straps over head.
2. Position the centre of the harness as far as possible at the back of head.
3. Gradually tighten the harness, starting with the lower straps then upper straps. Do not over-tighten.
4. Place palm of hand over mask inlet, breathe in and hold breath. The mask should collapse onto the face and remain so as long as
breath is held. This confirms that the mask is correctly sealed. If the mask returns to its initial position whilst the breath is held, readjust
the harness straps and repeat the air-tightness test.
•
If an effective face seal cannot be achieved, DO NOT USE the mask. See the maintenance instructions.
•
Check that there is no hair between the mask and the face. Whiskers, a beard or spectacle arms can also affect the air-
tightness of the mask.
•
Always make sure that the respiratory protection equipment attached to the mask is suitable for the intended use.
•
In normal use, breathe slowly and regularly.
•
If the mask or the attached respiratory equipment should fail, leave the contaminated area immediately.
•
Never remove the mask before leaving the contaminated area.
•
When removing the mask, take all necessary precautions to avoid inhaling dust or contaminants retained on the external
surface of the mask.
