This standard providn information for ihr selection, u-ir. and car* of respiralorv protective equipment Irrspirniort). The tarin "respirator" in Ihia standard in ward inclusively and applies lo atmosphrre-supplving and air purify mg drvicra dial provide breathable air lo the wearer thin the limila of die equipment. whatever the aourre of air. This atandard dora not apply for exposure to air borne radioactive contamination for which apeetal con sideration may be neceaaarv
2. GENERAL
2.1 Respiratory protective equipment should not be used as a substitute for adequate exhaust ventilation or other engineering eontroi methods.
2.3 Respiratory protective equipment shall be worn at alt limes where the atmosphere may be harmful lo env ploy res due lo unusual condidons. and where work 1ne-'essary in contaminated or oat gen-deficient, confined an-as.
Z2.1 M hen the air is defiriral in oxy gen. the tv mgtoins range from increased volume of breathing and ac celeration of pulse rale to unconsciousness and death, defending upon oxy gen content and the degree of a per son's activity. Unaansdausnass is immadiota whan a mtm breathes pur* nitrogen and daath may follow in a loir minutas.
2.2.2 An oxygen deficiency mav indicate a hazard in addition to inert gas: eg. flammabiJily (see 4.4). skin toxicity, or absorption through the akin, particularly hydrogen cyanide. Threshold limit values (TL\'*) of air eoMaminants are given in Standard S2T. Portable oxy. per and toxic-gas detectors art covered in Standard S3T.
2.3 Pure oxygen shall aot be used in atmospheresupplying respirators.

5.1 In general, in choosing a respirator, die following factors should be considered: (a) nature of the liuzard. lb) fvrriiv of the luzurtl. Ir) type of contaminant, (d) conrentratmr of die rontaminant. (e) period protection is reiiuned. ifi loraiion of llie contaminated area with respect iu a -ource of respirable air. (g) expected activity of die nearer. (li) operating chararteristics and limita tions of die mailable respirators, (i) safety regulations of sMir or luial governments (see Tabic 2).
5.1 1 'pparatus classified for 30-minule service time, ur longer, 'should be used for entry into an irrespiraMs atmosphere. In certain casea. 15-minute unit* may be |ierimiied. depending upon local conditions.
5.1.2 Duration ratings (or self-contained apparatus are based upon moderate work rule, brevier life of an air w Under w ill be ies for greater work rate.

combination air-line respirator und srlf-ctinUtiaed lircathmg apparatus 'hull hr used only for egress in eu-ui the hose-line supply of air is interrupted. The v olume ol this evil supply may vary for different applications, but'hull be ample to ullow the worker suflicirnt air to escape from the contaminated urea. In any case, this supply shall not be less than J minute*.
5.1.4 \n unconlaminated supply of air must be assured when using a hose mask with blower.
5.1.5 Schedule 13E of the l. S. Bureau f Mines on self-contained breathing apparatus requires u remainmg service-life indicator or warning for compressed breathing air (except for self-rescue, which has a mod* mum ruled service lime of 30 minutes). Some equipment now on plants may not have these alarms. Thesr can und should be ubiwned from equipment suppliers for appara tus not so equipped.
5.1.S.I When the device is a combination selfcontained breathing apparatus und air-line respirator Isupplied-air respirator), cither a manual or automatic valve(s) shall be provided to change to the self-contained air supply if the air-line supply (uils. und to prevent the wearer breathing contaminated air from the outside atmosphere. If a munuu) valve is provided, it shall be easily operable nod located in a position which is conlenient to the weurer. If an automatic valve is provided. a warning also shall be provided to alert the wearer that lie is breathing from Ihe self-contained air supply. It) when his normul air-line supply fail*, or (2) when the self-contained air supply falls below 95 percent of its full container pressure. \ quick disconnect und check valve shall be provided between the uppurutus and the air-line supply hose to permit ready escape from the area, and to prevent loss of breathing air from the dev ice or inhaling the surrounding atmosphere, respectively.
5.2 Tuble 3 lists the hazards and the respirators that are recommended to afford respiratory protection against them. By reference to this table, and by considering the foregoing factors, the user can determine the type of respirator that should be used.
6. PRECAUTIONS
6.1 Purchased cy finders of breathing air should be analy ted for o xy gen and carbon monoxide content before use. This analysis normally should be done by die plant (see S3T). Mso. (he water content of cy linder air used for air masks should be below the dew poim for the lowest prob able temperature to be encountered. This is necessary to prev ent (reeieup und stoppuge of uir flow- to the mask. Drw points at v ariout temperatures cats be obtained from the "Handbook of Compressed Cases."

7.2 Procedures Applicable to All Ratptrotore-'
7.2.1 Inspection. All retpirator* eball be inspected at regular interval* to make sure that they art ready to ate. It it good practice to integrate tbe retpiratory and
firewntjapuieber inspection and maintenance prapram.
Maintenance. When It is necessary to replace worn or deteriorated parts, only (boa* made specifically for thr device abouid be used; and tbe repair work abouid be accomplished by traiaed personnel. For most plants, it is preferable that part* of thi* type be replaced at a unit or rtturnad to tb* manufacturer (or repair.
7.2J Cleaning and Disinfading. Respiratory pro tective equipment, except canister* and cartridgra. should be daaacd and diaiafected after each at*, unless assigned to individuals. Rttpiratory cqaipmtat can bt cleaned with detergent and lukewarm water (lata than 125 F) by band brushing or agitation ia a washing machine, rinsed, and dried. The qaateraary ammonium salt dis infectants* are recommended for sterilising rttpiratory device*. Riate completely in clean, warm water. Assure thorough drying of mask and demand apparatus tfttr cleaning to prevent irming if used ia cold weather.
7.2A Storage. All respiratory protective equipment should be stored ia a dtaa, cool, dry' plae*. out of direct sunlight, under conditions of moderate temperature (tee Chemox mask in Table 2B).
