Those issued for the exclusive use of one worker are to be cleaned after each day's use, or more often if necessary. Those used by more than one worker are to be thoroughly cleaned and disinfected after each use. Cleaning this equipment must be included in the training and use of the equipment. Aside from understanding how to use the equipment for maximum possible protection, cleaning is of paramount importance. 6. A log shall be maintained by the RIG OPERATOR that documents the cleaning and maintenance of respiratory protective equipment. 7. Respiratory protective equipment shall be stored in a convenient, clean and sanitary location. One practical method for keeping this equipment clean and ready for use is to cover the storage cases with a tear-away plastic trash bags. This equipment must always be ready for immediate emergency use. This is possible only if it is stored properly. 8. Respiratory protective equipment shall be inspected during cleaning. Worn or deteriorated parts shall be replaced. Respiratory protective equipment for emergency use, such as self-contained devices, shall be thoroughly inspected by the RIG OPERATOR at least once a month and after each use.

The RIG OPERATOR is responsible _____________________________________________________________________________________________________ REV. JUNE 2004 Safety Requirement for Drilling & Workover Rigs -- Page 15 of 95 --
    • for knowing what respiratory exposures may be present and must alert all personnel when protective equipment is required. The level of exposure to a given substance is determined by continuous area monitoring, personal monitoring and warning devices, or from studying the Material Safety Data Sheets (MSDS) for each substance used on the location, The RIG OPERATOR is responsible for requiring the use of the proper equipment at all times when exposure limits exceed acceptable limits. 10. There shall be regular inspection and evaluation to determine the continued effectiveness of the program. The RIG OPERATOR is responsible for his respiratory protection program. In meeting that responsibility a RIG OPERATOR must know that all equipment is in good condition and is ready for use when needed. A part of every LOSS PREVENTION inspection will be to evaluate the state of the entire respiratory protection program of each location visited. 11. Persons should not be assigned to tasks requiring the use of respiratory protective equipment unless it has been determined that they are physically able to work while wearing the equipment. Any employee who may, in the course of his employment, be required to wear respiratory protection equipment must pass an annual examination by a competent medical staff. This examination must include a pulmonary function test. 12. Compressed air used for breathing purposes shall comply with the standards recommended in G.I. 1780.001. COMPRESSORS THE COMPRESSOR FOR SUPPLYING BREATHING AIR SHOULD MEET THE REQUIREMENTS OF G.I. 1780.001. 1. Breathing air compressors should be equipped with necessary safety and standby devices. 2. Breathing air compressors should be situated so as to avoid entry of contaminated air. 3. They should be equipped with purifying sorbet beds and filters to further assure greater air quality. 4. They must be equipped with alarms to indicate compressor failure and/or overheating. _____________________________________________________________________________________________________ REV. JUNE 2004 Safety Requirement for Drilling & Workover Rigs -- Page 16 of 95 --
    • 5. Oil lubricated compressors must have a high-temperature or carbon monoxide alarm or both. If only a high-temperature alarm is used, the air must be frequently tested for carbon monoxide to insure that the air meets the specifications as described in G.I. 1780.001. 6. Air samples from the breathing air compressor shall be tested, at least once in every six months, by an independent organization to ensure the air quality continues to meet the following air purity standards: AIR PURITY STANDARDS Limits have been established for breathing air quality. Air suitable for human respiration must meet minimum standards as established by various governing bodies, including the Compressed Gas Association. The following chart provides the maximum allowable contaminant allowed under the C.G.A. standard. COMPONENT C.G.A. STANDARD Oxygen % by volume 19 - 23% Carbon Dioxide, by 0.10% max. Volume (1000 ppm) Carbon Monoxide 10 ppm Oil Vapor (< 1 mg/liter @ STP) Water Saturated Odor None Particulates and Solids None The standards cited above are usually referred to as "Grade D", in reference to the Compressed Gas Association Table No.1 These standards apply to compressed air for use in filling open circuit breathing systems. HOW MUCH BREATHING AIR? In reality, each man should be trained and drilled to determine his own duration by using the Self-contained Breathing Apparatus (SCBA) under extremely strenuous working conditions. Many factors come into play that may greatly reduce the rated duration; therefore, one should not expect to obtain the exact time rating, without taking into consideration the size of the person, physical condition, breathing habits, adequate mask seal, etc. _____________________________________________________________________________________________________ REV.
