5 Change the mask immediately if breathing becomes difficult or the mask becomes damaged or distorted.

6 Change the mask if a proper face seal cannot be achieved.


Fitting Check


1 Hold the particle filtering half mask in position over the nose and mouth.

2 Pull lower strap over the head and fit around the back of the neck.

3 and pull the upper strap over the head positioning it just above the ears.

4 Ensure the nose clip is securely moulded around the nose, resting the ends against the cheek to obtain a good seal.

5 To check for proper fit, cup both hands over the mask and exhale vigorously. If air leaks around the nose, tighten the nose clip, if air leaks around the edge, reposition the headharness for better fit.

6 Repeat adjustments until the mask is sealed properly.

7 If a proper seal cannot be achieved do not enter the contaminated area or it may cause illness.


1 Store the mask in a sealed container away from contaminated areas when not use.
