The flexibility of the facepiece is suitable.The elastic straps have elasticity and can be adjusted at random to ensyre a comfortable,leak-free fit. Large triangular lenses are manufactured from optical plastic and surface treated specially. The lenses provide a wide visual field and excellent optical properties and have good abrasion and shook resistance.
The canister is filled with impregnated carbon of good quality and high efficiency filter paper and high efficiency filter paper and can filter out toxic gases and particulate aerosol from the influent air except carbon monoxide. The canister has a low resistance,light weight and long life.

3. USE AND MAINTENANCE
(1),The mask is divided into three sizes (small,medium dan large on the left lower part of the faceblank with a number:1(small),2(medium) or 3(la-rge).The user chooses a suitable mask according to the user’s head shape. If the user’s eyes after the mask has been worn are at the level of about 10 mm above the horizintal center line lf lenses , it si shown that the seleced size of the mask is suitsble. If the eyes are above the value of 10mm,the mask is too small . If the eyes are below the value ,the mask is too large.
(2),Use of drinking device. A special canteen cap should be screwed previously to the canteen .when the wearer needs to drink water ,unscrew the protective covers from the canteen cap and the water inlet valve,screw the ends of the connecting tube to the canteen cap and the water inlet valve,actuate the water inlet valve by hand to keep a suction tube in the mouth.
(3),The complete mask, particularly the lenses and the expiratory valve, should be kept clean. If necessary the lenses and the expiratory valve may be washed with clear water.
(4),the canister can devreaseits adsorption capacity for toxic gases after it has absorbed the moisture. The closure cap and the plug should ususlly be attached to the canister to prevent the ingress of moisture.
(5),The gas masks should bestored in a cool dry place. If the masks are not in use for a longer time, a support should be placed in each faceblank to prevent the deformation. The facepiece must not contace organic solvent.
