The purpose of the regulations contained in this part 84 is: (a) To establish procedures and prescribe requirements which must be met in filing applications for approval by the National Institute for Occupational Safety and Health of respirators or changes or modifications of approved respirators; (b) To establish a schedule of fees to be charged each applicant for the inspections, examinations, and testing conducted by the Institute under the provisions of this part; (c) To provide for the issuance of certificates of approval or modifications of certificates of approval for respirators which have met the applicable construction, performance, and respiratory protection requirements set forth in this part; and (d) To specify minimum requirements and to prescribe methods to be employed by the Institute and by the applicant in conducting inspections, examinations, and tests to determine the effectiveness of respirators used during entry into or escape from hazardous atmospheres. § 84.2 Definitions. As used in this part (a) Applicant means an individual, partnership, company, corporation, association, or other organization that designs, manufactures, assembles, or controls the assembly of a respirator and who seeks to obtain a certificate of approval for such respirator. (b) Approval means a certificate or formal document issued by the Institute stating that an individual respirator or combination of respirators has met the minimum requirements of this part, and that the applicant is authorized to use and attach an approval label to any respirator, respirator container, or instruction card for any respirator manufactured or assembled in conformance with the plans and specifications upon which the approval was based, as evidence of such approval. (c) Approved means conforming to the minimum requirements of this part. (d) Auxiliary equipment means a selfcontained breathing apparatus, the use of which is limited in underground mine rescue and recovery operations to situations where the wearer has ready access to fresh air and at least one crew equipped with approved self-contained breathing apparatus of 2 hours or longer rating, is in reserve at a fresh-air base. (e) Certification and Quality Assurance Branch means the Certification and Quality Assurance Branch, Division of Safety Research, Appalachian Laboratory for Occupational Safety and Health, National Institute for Occupational Safety and Health, 1095 Willowdale Road, Morgantown, West Virginia 26505-2888. (f) Compressed-breathing gas means oxygen or air stored in a compressed state and supplied to the wearer in gaseous form. (g) dBA means sound pressure levels in decibels, as measured with the Aweighted network of a standard sound level meter using slow response. (h) Dust means a solid mechanically produced particle with a size ranging from submicroscopic to macroscopic. (i) Respirators for entry into and escape from means respiratory devices providing protection during entry into and escape from hazardous atmospheres. (j) Respirators for escape only means respiratory devices providing protection only during escape from hazardous atmospheres. (k) A facepiece or mouthpiece is a respirator component designed to provide a gas-tight or dust-tight fit with the face and may include headbands, valves, and connections for canisters, cartridges, filters, or respirable gas source. (1) Final inspection means that activity carried out on a product after all manufacturing and assembly operations are completed to insure completeness and adherence to perform ance or other specifications, including satisfactory appearance. (m) Fume means a solid condensation particle, generally less than 1 micrometer in diameter. (n) Gas means an aeriform fluid which is in a gaseous state at ordinary temperature and pressure. (0) Hazardous atmosphere means: (1) Any atmosphere containing a toxic or disease producing gas, vapor, dust, fume, mist, or pesticide, either immediately or not immediately dangerous to life or health; or (2) Any oxygen-deficient atmosphere. (p) A hood or helmet is a respirator component which covers the wearer's head and neck, or head, neck, and shoulders, and is supplied with incoming respirable air for the wearer to breathe. It may include a headharness and connection for a breathing tube. (q) Immediately dangerous to life or health means conditions that pose an immediate threat to life or health or conditions that pose an immediate threat of severe exposure to contaminants, such as radioactive materials, which are likely to have adverse cumulative or delayed effects on health. (r) Incoming inspection means the activity of receiving, examining, and accepting only those materials and parts whose quality conforms to specification requirements. (s) In-process inspection means the control of products at the source of production and at each step of the manufacturing process, so that departures from specifications can be corrected before defective components or materials are assembled into the finished product. (t) Institute means the National Institute for Occupational Safety and Health, Department of Health and Human Services. (u) Liquefied-breathing gas means oxygen or air stored in liquid form and supplied to the wearer in a gaseous form. (v) Mist means a liquid condensation particle with a size ranging from submicroscopic to macroscopic. (w) MSHA means the Mine Safety and Health Administration, U.S. Department of Labor. |
