XVII (7-1-91 Edition) (5) When limitations or precautions are Indicated by the manufacturer, they shall be transmitted to the user and care taken to see that such limita tions and precautions are strictly ob served. <8) Design, construction, testing, and use of devices for eye and face protec tion shall be In accordance with Amer ican National Standard for Occupa tional and Educational Eye and Face Protection, Z87.1-1P68. 0 1910.134 Respiratory protection. (a) Permissible practice. (1) In the control of those occupational diseases caused by breathing air contaminated with harmful dusts, fogs, fumes, mists, gases, smokes, sprays, or vapors, the primary objective shall be to prevent atmospheric contamination. This shall be accomplished as far as feasible by accepted engineering control measures (for example, enclosure or confine ment of the operation, general and local ventilation, and substitution of less toxic materials). When effective engineering controls are not feasible, or while they are being Instituted, ap propriate respirators shall be used pursuant to the following require ments. (2) Respirators shall be provided by the employer when such equipment Is necessary to protect the health of the employee. The employer shall provide the respirators which are applicable and suitable for the purpose Intended. The employer shall be responsible for the establishment and maintenance of a respiratory protective program which shall Include the requirements outlined In paragraph (b) of this sec tion. (3) The employee shall use the pro vided respiratory protection In accord ance with Instructions and training re ceived. (b) Requirements for a minimal ac ceptable program. (1) Written stand ard operating procedures governing the selection and use of respirators shall be established. (3) Respirators shall be selected on the basis of hazards to which the worker Is exposed. (3) The user shall be instructed and trained In the proper use of respira tors and their " 'Itatlora. (4) [Reserved] (5) Respirators shall be regularly cleaned and disinfected. Those used by more than one worker shall be thor oughly cleaned and disinfected after each use. <6) Respirators shall be stored In a convenient, clean, and sanitary loca tion. (7) Respirators used routinely shall be Inspected during cleaning. Worn or deteriorated parts shall be replaced. Respirators for emergency use such as self-contained devices shall be thor oughly Inspected at least once a month and after each use. <B) Appropriate surveillance of work area conditions and degree of em ployee exposure or stress shall be maintained. ,, (0) There shall be regular Inspection and evaluation to determine the con tinued effectiveness of the program. (10) Persons should not be assigned to tasks requiring use of respirators unless It has been determined that they are physically able to perform the work and use the equipment. The local physician shall determine what health and physical conditions are pertinent. The respirator user's medi cal status should be reviewed periodi cally (for instance, annually). i (11) Approved or accepted respira tors shall be used when they are avail able. The respirator furnished shall provide adequate respiratory protec tion against the particular hazard for which It Is designed In accordance with standards established by compe tent authorities. The U.S. Department of Interior, Bureau of Mines, and the U.8. Department of Agriculture are recognized as such authorities. Al though respirators listed by the TIB. Department of Agriculture continue to be acceptable for protection against specified pesticides, the U.S. Depart ment of the Interior, Bureau of Mines, Is the agency now responsible for test ing and approving pesticide respira tors. (c) Selection of respirators. Proper selection of respirators shall be mads according to the guidance of American National Standard Practices for Respt1 ratory Protection Z8B.2-196P. (d) Air qualify.

(II) The compressor for supplying air shall be equipped with necessary safety and standby devices. A breath ing air-type compressor shall be used. Compressors shall be constructed and situated so as to avoid entry of con taminated air Into the system and suit able ln-llne air purifying sorbent beds and fitters Installed to further assure breathing air quality. A receiver of sufficient capacity to enable the respi rator wearer to escape from a contami nated atmosphere In event of compres sor failure, and alarms to Indicate compressor failure and overheating shall be Installed In the system. If an oil-lubricated compressor Is used. It shall have a high-temperature or carbon monoxide alarm, or both. If shall be adequately instructed to Insure that the correct respirator Is issued. (3) Written procedures shall be pre pared covering safe use of respirators In dangerous atmospheres that might be encountered In normal operations or in emergencies. Personnel shall be familiar with these procedures and the available respirators. (t) In areas where the wearer, with failure of the respirator, could be over come by a toxic or oxygen-deficient at mosphere, at least one additional man shall be present.

(4) Respiratory protection Is no better than the respirator In use, even though It Is worn conscientiously. Fre quent random Inspections shall be con ducted by a qualified Individual to assure that respirators are properly se lected, used, cleaned, and maintained. (8) For safe use of any respirator. It Is essential that the user be properly Instructed In Its selection, use, and maintenance. Both supervisors and workers shall be so instructed by com petent persons. Training shall provide the men an opportunity to handle the respirator, have It fitted properly, test Its face-piece-to-face seal, wear It In normal air for a tong familiarity period, and, finally, to wear ft In a test atmosphere. (1) Every respirator wearer shall re ceive fitting Instructions Including demonstrations and practice 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 good face seal. Such conditions may be a growth of beard, sideburns, a skull cap that projects under the facepiece, or temple pieces on glasses. Also, the ab sence of one or both dentures can seri ously affect the fit of a facepiece. The worker's diligence In observing these factors shall be evaluated by periodic check. To assure proper protection, the facepiece fit shall be checked by the wearer each time he puts on the respirator. This may be done by fol lowing th manufacturer's facepiece fitting Instructions. (ID Providing respiratory protection for individuals wearing corrective glasses la a serious problem. A proper seal cannot be established If the temple bars of eye glasses extend through the sealing edge of the full facepiece. As a temporary measure, glasses with short temple bars or with out temple bars may be taped to the wearer's head. Wearing of contact lenses In contaminated atmospheres with a respirator shall not be allowed. Systems have been developed for mounting corrective lenses Inside full facepieces. When a workman must wear corrective lenses as part of the facepiece, the facepiece and lenses shall be fitted by qualified Individuals to provide good vision, comfort, and a gas-tight seal. (Ill) If corrective spectacles or gog gles are required, they shall be worn so as not to affect the fit of the facepiece. Proper selection of equipment will minimize or avoid this problem. (f> Maintenance and core of respira tors. (1) A program for maintenance and care of respirators shall be adjust ed to the type of plant, working condi tions, and hazards Involved, and shall Include the following basic services: (l> Inspection for defects (Including a leak check), (II) Cleaning and disinfecting, (III) Repair, (Iv) Storage Equipment shall be properly main tained to retain Its original effective ness. (2) (1) All respirators shall be In spected routinely before and after each use. A respirator that Is not rou tinely used but Is kept ready for emer gency use shall be Inspected after each use and at least monthly to assure that It Is In satisfactory working condi tion. (II) Self-contained breathing appara tus shall be Inspected monthly. Air and oxygen cylinders shall be fully charged according to the manufactur er's Instructions. It shall be deter mined that the regulator and warning devices function properly. (III) Respirator Inspection shall In clude a check of the tightness of con nections and the condition of the facepiece, headbands, valves, connecting tube, and canisters. Rubber or elasto mer parts shall be Inspected for pli ability and signs of deterioration. Stretching and manipulating rubber or elastomer parts with a massaging action will keep them pliable and flexible and prevent them from taking a set during storage. (Iv) A record shall be kept of Inspec tion dates and findings for respirators maintained for emergency use. (3) Routinely used respirators shall be collected, cleaned, and disinfected as frequently as necessary to Insure that proper protection Is provided tor the wearer.
