By reference to this table, and by eonidering the foregoing factors, the user can determine the type of respirator that should be used. 6. PRECAUTIONS 6.1 Purchased cy finder* of breathing nir should be antly sed for oxy gen and carbon monoxide content before use. This analysis normally should be done by the plum (tee S3T).

It it good practice to integrate tbe respiratory and firrustJaituNSir Inspection and maintenance program. Maintenance. When It is necessary to replace worn or deteriorated parts, only (bos* made specifically for the device should be used; and the repair work should be accomplished by trained personnel. For most plants, it is preferable that part* of thie type be replaced as s unit or returned to the manufacturer (or repair. 7.2J Goaniflf and Ditinfading. Respiratory pro tective equipment, except canisters and cnrtridgr*. should be ekaeed and disinfected after each as*, unless assigned to individuals. Respiratory equipment can be cleaned with detergent sad lukewarm water (let* then 123 F) by band breaking or agitation in a washing machine, rinsed, and dried. The qaattraary ammonium salt dis infectants* are recommeaded for sterilising respiratory devices. Rinse completely in clean, warm water. Assure thorough drying of meek end demand apparatus after cleaning to prevent fresting if used in cold weather. 7.2 A Stareg*.
