GENERAL PROVISIONS. A. Purpose. These rules require minimum operational and equipment standards for air compressors that supply compressed air used in self-contained breathing apparatus. B. Definitions. 1. Breathing Apparatus. "Breathing Apparatus" means any breathing device, either high or low pressure which is used to sustain human life under adverse conditions. 2. Department. "Department" mans the Department of Human Services. 3. Suppliers of Compressed Air. "Suppliers of Compressed Air" means organization, agency, individual, firm, partnership or corporation that provides compressed air to be used in self-contained breathing apparatus. C. Licensing. 1. It is unlawful for any supplier of compressed air to fill or supply any breathing apparatus with life supporting gases in the State of fb88 unless licensed to do so by the Department. 2. Fire departments are exempt from the licensing requirements as long as the use of the apparatus is restricted to departmental use in fighting fires. 3. The annual license fee shall be $10. 4. All licenses issued shall expire on March 31st, of each year. D. Variance. 1. When compliance with the provisions of these regulations would involve hardship out of proportion to the increase in health protection secured thereby, the Department may, upon consideration permit modification of these regulations. E. Posting. These rules shall be posted conspicuously on the premises. F. Log. 1. A log shall be maintained documenting: (1) hours of compressor operation each day of use, (2) dates and types of filter changes, (3) dates of over-haul, maintenance and oil changes, (4) results of compressed air analysis when performed, (5) name of person(s) receiving the air. 2. This log shall be available for audit by a representative of the Department or other duly authorized agencies. 2. OPERATIONAL AND EQUIPMENT STANDARDS. A. Air Standards. Components in the compressed air shall not exceed the limits set forth in the following table: Oxygen ... Not less than 19%/vol. Odor....See Note No. 1 Carbon Monoxide............10 ppm Other...Contaminants Carbon Dioxide..............500 ppm deleterious to Hydrocarbons (condensed) 5mg/m3 health shall not be present. %/Vol percent by volume ppm parts per million by volume mg/m3 milligrams per cubic meter of air Note No. 1 - Odor - Although air normally has a slight Odor, the presence of a pronounced odor shall render the air unsatisfactory. B. Air Processing Equipment. Air processing involves the compression, purification and proper storage of the purified air. 1. Compressor. The air compressor shall be of a type, size and capacity in keeping with the intended usage; and shall incorporate the equipment and features necessary to assure efficient operation and to safeguard against malfunction or human error. The air compressor shall include: a. An Inlet Filter: Positioned to exclude airborne particles, exhausts of automotive vehicles and undesirable odors or other contaminants. b. Pressure Control Device: To prevent the compressor from exceeding a pre-set pressure. c. Temperature Control Device: To prevent the compressor from over-heating, a temperature sensing probe shall be affixed at the hottest location in the compressor d. Running Time Recorder: To record the actual running hours of the compressor. e. Inter-Coolers On Multistage Compressors; To cool the compressed air between each compression stage. C. Air Purification. The air purification system shall consist of: 1. Aftercooler: To cool the compressed air to cause water and oil vapors to condense. 2. Condensate Separator: To remove condensed water and oil droplets. 3. Water and Oil. Removal Device: To remove remaining water and oil vapors. 4. Odor Removal Device: To remove undesirable odors. D. Air Cylinders. Air filling stations shall not fill self-contained underwater breathing apparatus that do not have U.S. Department of Transportation - DOT (or Interstate Commerce Commission ICC, if manufactured prior to January 1, 1970), marking showing that the cylinder has been hydrostatically TESTED WITHIN FIVE YEARS OF THE DATE OF FILLING. Cascade system cylinders shall be hydrostatically tested at 5 year intervals. E. Protective Barriers. 1. Protective barriers or isolated areas shall be provided to protect personnel against possible air cylinder failure during filling operations. 2. If space considerations absolutely prevent isolating the filling area, or if no protective barriers are used or such barriers are deemed to be inadequate by the Department, then a large plastic container filled with water shall be used to contain the air cylinders during the filling operation. 3. Under no circumstances, shall an air cylinder be filled in a metal water container.
