7.2.4Periodically inspect and clean the foam filter and screen in the alternate air control valve. Replace the foam filter at first sign of blockage or deterioration. (See Section 9.8)
7.2.5The inner collar is a very important factor in controlling air escape from the helmet and preventing ingress of dust. The elastic properties of the collar are intended to provide a snug fit on the user’s neck. The collar must be replaced before it is stretched to the point where it no longer fits snugly around the neck.
7.2.6The outer cape provides protection from rebound- ing abrasive and from abrasive ingress into the helmet. Inspect the outer cape frequently for wear. Replace the cape before holes are worn through, or any wear occurs that prevents the cape from providing the protection for which it is intended.
7.3Cleaning and Disinfecting
7.3.1Respirators must be cleaned and disinfected as frequently as necessary to ensure that proper protection is provided to the wearer. Respirators used by more than one person must be cleaned and disinfected after each use. See Section 8.0 for cleaning instructions. [Reference OSHA Regulations 1910.134 (b)(5); 1910.134 (f)(3)].
7.4Repair (Service Maintenance)
7.4.1Replacement or repairs shall be done only by trained persons, using genuine Clemco parts designed for the respirator. No attempt shall be made to replace com- ponents or to make adjustment or repairs beyond the manufacturer’s recommendations. See Sec. 9.0 for ser- vice instructions. [Reference OSHA Regulations 1910.134 (f)(4)].
7.5Storage
7.5.1Daily Storage
7.5.1.1When the respirator is not in use, it must be stored in a clean, dry area. Hang the respirator by the strap provided on the top. Do not tuck the cape inside the helmet. Let the cape hang loose to allow air to circulate, to dry condensation from the cape and from inside the helmet.
7.5.2Long-term storage
7.5.2.1After inspection, cleaning and thorough drying, and after necessary repairs are made, the cape should be tucked inside the helmet. The respirator shall then be placed in a plastic bag and the bag sealed to keep out dust and moisture. Place the bag in a clearly marked carton and
store it in a clean, dry place. [Reference OSHA Regula- tions 1910.134 (f)(5)].
8.0CLEANING
! CAUTION
Follow washing instructions as described in this section. Do not use any caustic chemicals or solvents that may be irritating or harmful to the user, or which change the properties of the mate- rials used in any part of the respirator.
8.1Outer Cape
8.1.1The cape can be machine washed using warm water and mild detergent. Dry in a clothes dryer at the lowest temperature setting. Do not dry clean. See Section 9.4 for removal and installation instructions.
8.2Inner Collar
8.2.1The removable inner collar should be frequently washed to remove
8.2.2The inner collar may be either washed or replaced separately or with the outer cape. To wash separately, unzip the collar and machine wash with warm water and mild detergent. Tumble dry in a clothes dryer at the lowest temperature setting. Do not dry clean.
8.3Sweatband and Suspension
8.3.1The sweatband, suspension, suspension strap, and chin strap should be washed using warm water and mild detergent. See Section 6.2 for removing the suspen- sion.
8.4Helmet Assembly
8.4.1The helmet assembly should be wiped clean with mild detergent and water. DO NOT IMMERSE THE HEL- MET IN WATER! While this does not permanently dam- age the helmet, it will require an extended drying period.
8.4.2Care must be used to prevent abrasive entry when putting on or removing the respirator and when changing lenses. Vacuum the inside of the helmet to remove any abrasive.
