Table C (Continued)—ANSI Z88.2–1980 and OSHA 1984 Assigned Protection Factors.
| Type of Respirator | Permitted for Use in Oxygen-Deficient Atmosphere | Permitted for Use in Immediately-Dangerous-to-Life-or-Health Atmospheref | Respirator Protection Factor | |
| Qualitative Test | Quantitative Test | |||
| Air-line, demand, quarter-mask or half-mask facepiece with or without escape provisions?,? | Yesf | No | 10 | As measured on each person, but limited to the use of the respirator in concentrations of contaminants below the immediately-dangerous-to-life-or-health (IDLH) values. |
| Air-line, demand, full facepiece, with or without escape provisions | Yesf | No | 100 | As measured on each person, but limited to the use of the respirator in concentrations of contaminants below the immediately-dangerous-to-life-or-health (IDLH) values. |
| Air-line, continuous-flow or pressure-demand type, any facepiece, without escape provisions? | Yesf | No | N/A | N/A |
| No tests are required due to positive pressure operation of respirator. The maximum protection factor provided by the respirator is limited to use of the respirator in concentrations of contaminants below the immediately-dangerous-to-life-or-health (IDLH) values. | ||||
| Air-line, continuous-flow or pressure-demand type, any facepiece, without escape provisions?,? | Yesf | Yes | N/A | N/A |
| No tests are required due to positive pressure operation of respirator. The maximum protection factor is 10 000 plus.h | ||||
| Air-line, continuous-flow, helmet, hood, or suit, without escape provisions? | Yes? | No | N/A | N/A |
| No tests are required due to positive pressure operation of respirator. The protection factor provided by the respirator is limited to the use of the respirator in concentrations of contaminants below the immediately-dangerous-to-life-or-health (IDLH) values. | ||||
| Air-line, continuous-flow, helmet, hood, or suit, with escape provisions? | Yes? | Yes | N/A | N/A |
| No tests are required due to positive pressure operation of respirator. The maximum protection factor is 10 000 plus.h | ||||
| Hose mask, with or without blower, full facepiece | Yesf | No | 10 | As measured on each person, but limited to the use of the respirator in concentrations of contaminants below the immediately-dangerous-to-life-or-health (IDLH) values. |
| Self-contained breathing apparatus, demand-type apparatus or negative-pressure-type closed-circuit, quarter-mask or half-mask facepiecec | Yesf | No | 10 | As measured on each person, but limited to the use of the respirator in concentrations of contaminants below the immediately-dangerous-to-life-or-health (IDLH) values. |
| Self-contained breathing apparatus, demand-type open-circuit or negative-pressure-type closed-circuit, full facepiece or mouthpiece/nose clampc | Yesf (Yes?, if respirator is used for mine rescue and mine recovery operations.) |
No (yes, if respirator is used for mine rescue and mine recovery operations.) | 100 | As measured on each person, but limited to the use of the respirator in concentrations of contaminants below the immediately-dangerous-to-life-or-health (IDLH) values, except when the respirator is used for mine rescue or mine recovery operations. |
