CDIM Corporate Safety Program ChM HSP-2. Respiratory Protection °•°� ..•. Rev. 1 08/23/2018 • The moisture content in the cylinder does not exceed a dew point of-50 degrees Fahrenheit (°F) (45.6 degrees Celsius [°C])at 1 atmosphere pressure. Compressors used to supply breathing air to respirators must be constructed and situated to: • Prevent entry of contaminated air into the air-supply system; • Minimize moisture content so that the dew point at 1 atmosphere pressure is 10 °F (5.56°C) below the ambient temperature; • Have suitable in-line air-purifying sorbent beds and filters to further ensure breathing air quality. Sorbent beds and filters shall be maintained and replaced or refurbished periodically following the manufacturer's instructions; and • Have a tag containing the most recent change date and the signature of the person authorized by the employer to perform the change. The tag shall be maintained at the compressor. For compressors that are not oil-lubricated, carbon monoxide levels in the breathing air cannot exceed 10 ppm. For oil-lubricated compressors, a high-temperature or carbon monoxide alarm, or both, must be used to monitor carbon monoxide levels. If only high-temperature alarms are used, the air supply shall be monitored at intervals sufficient to prevent carbon monoxide in the breathing air from exceeding 10 ppm. Breathing air couplings must be incompatible with outlets for nonbreathable worksite air or other gas systems. No asphyxiating substance shall be introduced into breathing air lines. Breathing gas containers must be marked in accordance with the NIOSH respirator certification standard, 42 CFR part 84. All filters, cartridges and canisters used in the workplace must be labeled and color coded with the NIOSH approval label. The NIOSH approval label must not be removed and must remain legible. 6.11 Training All employees who are required to use respiratory protection (required or voluntary) must receive annual training that is comprehensive and understandable. The training should explain: • The need for a respirator and how improper fit, usage, or maintenance can compromise the protectiveness of a respirator; • The limitations and capabilities of a respirator; • The effective use of a respirator in emergency situations, including situations in which the respirator malfunctions; • Procedures for inspection, donning, use and removal of a respirator, and information about how to check its seals; • Procedures for maintenance and storage of a respirator; and • How to recognize medical signs and symptoms that may limit or prevent the effective use of respirators. Training will be repeated as necessary, and at least annually, to ensure that employees remain familiar with the proper use of respiratory protection. Retraining should be provided if: • Changes in the workplace or the type of respirator render previous training obsolete; • Inadequacies in the employee's knowledge or use of the respirator indicate that the employee has not retained the requisite understanding or skill; or • Any other situation arises in which retraining appears necessary to ensure safe respirator use. The training program should be evaluated at least annually by the HSPM to determine its continued effectiveness. Page 11 of 13
