(5) Instruction and training in actual use of the respirator (especially a respirator for emergency use) and dose and frequent super vision to assure that it continues to be properly and^eld training to recogcope with emergency situations. (7) Other special training aa needed for spe cial uae. Training shall provide the men an oppor tunity to handle the respirator, have it fitted property, test its facepiece-to-tace sol, wear it in normal air for a long familiarity period, and, finally, to wear it in a tat atmosphere. 00 0781^7 comp fOFNTTA AM ER IC AN N A TIO N A L STANDARD PRACTICES wtftprs (See 5.3 for specification* on respirable' Atmosphere-supplying respirators provide protection against oxygen defi ciency and most toxic atmotpherei. The breathing atmosphere is indepen dent of ambient atmoapheric conditions. General Limitations: Except for the supplied-air suit, no protection is provided against skin irritation by materials such as Ammonia and HCt, or against sorption of materials such as HCN, tritium, or organic phosphate pesticides through the skin. See 6.3.5.I. Facepieces present special problems to indi viduals required to wear prescription lenses (see 9.1 and 9.2). Self-Contained Breathing Apparatus (SCBA) The wearer carries his own breath ing atmosphere. Use is permissible in atmospheres immediately dan gerous to life or health. Limitations: The period over which the device will provide protection is limited by the amount of air or oxygen in the apparatus, the am bient atmospheric pressure (service life is cut in half by a doubling of the atmospheric pressure), and work load. A warning device shall be provided to indicate to the wearer when the service life has been reduced to a low level. Seme SCBA devices have a short service life (few minutes) and are suitable only for escape (self-rescue) fro an irrespirsbie atmosphere. " Lttiffulgtiona of SQ8A device*' Hhrirwnighlorhnlk e&dtt. Hod* ^service*'lifq^. eat) .the trainings Chaired eefrrtN (1) Closed-circuit SCBA The closed circuit operation con serves oxygen and permits longer service life. Hose Mask or Atr-Une Respirator The respirable air supply is not limited to the quantity the individual can carry, and the devices are light weight and simple. Limitations: The wearer is restricted in movement by the hoee or air-line and must return to a respirable atmosphere by retracing his route of entry. The hose or air-line is subject to being severed or pinched off. (1) Hose Mask (a) Hose mask with blower. If the blower fails, the unit still provides protection, although a negative pres sure exists in the facepiece during inhalation. Use is permissible in atmospheres immediately dangerous to life or health. (b) Hose mask without blower. Limited to use in atmospheres from which the wearer can escape un harmed without aid of the respirator. (2) Air-Line Respirators (ContinuousFlow, Demand and Pressure-Demand Types) The demand type produces a nega tive pressure in the facepiece on inhalation whereas continuous flow and pressure-demand types maintain Ceneral Limitations: Air-purifying respirators do not protect against oxygendeficient atmospheres nor against skin irritation by, or sorption through the skin of, airborne contaminants. See 6.3.1. and 6.3.5.1. The maximum contaminant concentration against which an air purifying respirator will protect is determined by the designed efficiency and capacity of the cartridge, canister, or filter. For gases and vapors and for particles having a TLV of less than 0.1 mg/m3, the maximum concentration for which the air purifying unit is designed is specified on the label. Respirators without a blower to maintain a constant positive pressure within the facepiece will not provide the maximum design protection specified unless the facepiece is care fully fitted to the wearer's face to prevent inward leakage. See 7.5. The time period over which protection is provided is dependent on canister, cartridge, or filter type, concentration of contaminant, and the wearer's respiratory rate. The proper type of canister, cartridge, or filter shall be selected for the particular atmosphere and conditions. Air-purifying respirators generally cause discomfort and objectionable resistance to breathing although these problems are minimized in blower-operated units. Respirator facepieces pre sent special problems to individuals required to wear prescription lenses. (See 9.1 and 9.2.) These devices do have the advantage of being small, light, and simple in operation. Gas- and Vapor-Removing Respirators Additional Limitations: No protec tion is provided against MUiHU|gt contaminants, unless specified on canister or cartridge label. A rise in canister or cartridge temperature indicates that a gas or vapor is being removed from the inspired air. This is not a reliable indicator of canister performance. An uncom fortably high temperature indicates a high concentration of gas or vapor and requires an immediate return to fresh air. Particulate-Removing Respirators Additional Limitations: Protect against non-volatile particles only. No protection against gases and vapors. The filter shall be replaced or cleaned when breathing becomes difficult due to plugging by retained particles. These respirators shall not be used during shot and sand blasting opera tions. Abrasive-blasting respirators shall be used.

Combination Self-Contained and Air-Line Respirators The equipping of an air-line respirator with a small cylinder of compressed air to provide an emergency air supply qualifies the respirator for use in immediately dangerous atmospheres. See 6.3.2. Combination Particulate and Vapor- and Cas-Rcmoving Respirators The advantages and disadvantages of the component parts of the combination respirator as described above will apply, Combination Atmosphere-Supplying and Air-Purifying Respirators The advantages and disadvantages, expressed above, of the mode of operation being used will govern. The mode with the greater limitations (air-purifying mode) will mainly determine the overall capabilities and limitations of the respirator since the wearer may for some reason fail to change the mode of opera tion even though conditions would require such change. 7.5 Facepiece Fit Testa sad Provedares. Every respirator wearer shall receive fitting in structions includinf demonstrations and prac tice in how the respirator should be worn, how to adjust it, and how to determine if it fits properly. Respirators shall not be worn when conditions prevent a cood face seal. Such con ditions may be a growth of beard, sideburns, a ahull cap that projects under the facepiece, or tempi# platen on glasses. Abo; the absence of one or both tfenturae can seriously affect the fit of n facepiece. The worker's diligence in ob serving these factors shall bo evaluated by periodic cbacfaL i To assure peeper protection, the facepiece fit **!1 be checked by the weerer each tone ha pits on the respirator. This mav be done by ( following the manufacturer's facepiece-fitting , instructions such as these two simple field testa: ^ (1) Positive Pressure Test Close the exhala tion valve and exhale gently into the facepiece. Hie face fit is considered satisfactory if a slight positive pressure can be built up inside the facepiece without any evidence of outward leakage of air at the seal. For moat respirators, this method of leak testing requires that the wearer first remove the exhalation valve cover and then carefully replace it after the test t (2) Neptive Pressure Teat Close off the inlet opening of the canister or cartridge(s) by covering with the palm of the hand(a) or by replacing the eealfs), inhale gently ao that the facepiece rolTepree slightly, and hold the breath for ten seconds.

Self-contained breathing apparatus shall be inspected monthly. Air and osygen cylinders dial) be fully charged according to the manu facturer's instructions. It shall be determined that the regulator and warning devices function properly. Respirator inspection shall include a check of the tightness of connections end the condition of the facepiece, headbands, valves, connecting tube, and canisters. Rubber or elastomer parts shall be inspected for pliability and signs of de terioration. U Clnatai al Disinfection. Routinely used respirators shell be collected, cleaned, end dis infected es frequently as necessary to insure that proper protection is provided for the wearer. Each worker should be briefed on the cleaning procedure and be assured that he will always receive a dean and disinfected respira tor. Such assurances are of greatest significance when respirators are not individually assigned to workers. Respirators maintained for emer gency uae ahall be cleaned and disinfected after each use. The following procedure is recommended for cleaning and disinfecting respinton: (1) Remove any filters, cartridges, or canis ters. (2) Wash facepiece and breathing tube in demer-disuifectant or detergent solution (see following paragraphs). Use a hand brash to fa cilitate removal of dirt. (3) Rinse completely in clean, warm water. (4) Air dry in a clean area. (5) Clean other respirator parts ss recom mended by msnufseturer. (6) Inspect vslves, headstraps, end other parts; replace with new parts if defective. (7) Insert new filters, cartridges, or canis ters; make sure seal is tight (8) Place in plastic bag or container for stor age. Cleaner-disinfectant solutions are available that effectively dean the respirator and contain bactericidal agent The bactericidal agent is generally a quaternary ammonium compound. The respirator may be immersed in the solution, rinsed in deen, warm water, and air dried.  *-1 * , done onto hr rm..;, t wamM ** to wmponent* or teZUS "*"*? rtpMin beyond the m*nStoS ?fducin* <^boa velvet S,/^etS1nmed *? theJnunuf*c- or repir t*chn>CMin for ad/wtment < 00 07R173 OONFIDFNTT At. &5 Storage* After inspection, cleaning, and necewaiy nptir, respirators shall be stored to protect against dust, sunlight, heat, extreme cold, esceawve moisture or damaging chemicals.
