General Cautions and Limitations for 13F - Self-Contained Breathing Apparatus
These limitations are by no means all inclusive. The respirator manufacturer may also identify further cautions and limitations for their respirators. In addition, regulatory agencies may also place a limit on the use of respirators in their standards.
|13F - Self-Contained Breathing Apparatus
|Entry Into and Escape Class
||Approved for respiratory protection during entry into or escape from oxygen-deficient atmospheres, gases and vapors
|Escape Only Class
||Approved for respiratory protection during escape only from oxygen-deficient atmospheres, gases and vapors
|Combination Self-Contained Breathing Apparatus and Supplied-Air Respirator Class (demand and pressure demand)
||Approved for respiratory protection during entry into and escape from oxygen-deficient atmospheres, gases and vapors, when using air-line air supply. If the self-contained breathing apparatus is to be used during entry, the SCBA must be classified for 15 minutes or longer service time and not more than 20 percent of the rated capacity of the air supply is used during entry
General Limitations - All SCBA
- Use only for temperatures above the temperature listed on the approval label.
- Approved only when compressed air reservoir is fully charged with air meeting the requirements of the Compressed Gas Association specification G-7.1 for Type 1, Grade D air, or equivalent specifications.
- The air container shall meet applicable DOT specifications.
- Use adequate skin protection when worn in gases or vapors that poison by skin absorption.
- Refer to approval label and instruction and maintenance manuals for additional information on use and maintenance of these respirators.
- In making renewals and repairs, parts identical with those furnished by the manufacturer under the pertinent approval shall be maintained.
- This respirator shall be selected, fitted, used and maintained in accordance with Mine Safety and Health Administration and other applicable regulations.
Recommendation - SCBA with Breathing Gas Cylinders
NIOSH recommends that SCBA be inspected weekly if stored and immediately before use if used regularly, for breathing gas pressure.
Additional Limitations - Closed Circuit
- If compressed air supply is used: Approved only when air reservoir is fully charged with air meeting the requirements of the Compressed Gas Association (CGA) Specification G-7.1 for Type 1, Grade D air, or equivalent specifications.
- If compressed oxygen or liquid oxygen is used: Approved for use only when the cylinder or container is charged with compressed oxygen or liquid oxygen meeting U.S.P. specifications.
- If enriched air is used: Approved for use only when the cylinder or container is charged with compressed gas meeting the requirements listed in Federal Register Vol. 20, No. 222, November 18, 1985. Oxygen in the facepiece shall not exceed 30 percent by volume under normal temperature and pressure conditions.
- If liquefied breathing air is used: Must meet both Type I gaseous air and Type II liquefied air specifications (1966 edition of CGA G-7.1).
- The oxygen container shall meet applicable DOT specifications.
- Provide proper care, training, and maintenance of the apparatus as specifically described in the manufacturer's instruction and maintenance manuals.
- After each use of each apparatus, a fully charged breathing gas container and a recharge of carbon dioxide scrubber shall be installed.
- Thorough cleaning and disinfecting of facepiece, breathing tube, and breathing bag must be done in accordance with the manufacturer's instructions.
|13F - Self-Contained Breathing Apparatus
|Open circuit pressure demand
||Negative pressure mode shall be used only when donning apparatus.
|Closed circuit pressure demand
||Do not use this apparatus where there is direct exposure to open flames or in high radiant heat. (This limitation applies to 100 percent oxygen apparatus only.)
|Open circuit (pressure demand, demand, or continuous flow)
||OSHA regulations require that escape respirators be inspected monthly.
||OSHA regulations require that escape respirators be inspected monthly. MSHA regulations require that self-rescuers that are carried be inspected daily.
|Combination Self-Contained Breathing Apparatus and Supplied-Air Respirators (demand and pressure demand)
||Use only the hose lengths and pressure ranges specified on the approval label. If the supplied air fails, open cylinder valve and proceed to fresh air immediately.
