OSHA Resp Prot
| Question | Answer |
|---|---|
| In the control of those occupational diseases caused by breathing air contaminated with harmful dusts, fogs, fumes, mists, gases, smokes, sprays, or vapors, what is the primary objective? | shall be to prevent atmospheric contamination. |
| A respirator shall be provided to each employee when? | such equipment is necessary to protect the health of such employee. |
| Air-purifying respirator means: | a respirator with an air-purifying filter, cartridge, or canister that removes specific air contaminants by passing ambient air through the air-purifying element. |
| Assigned protection factor (APF) means: | the workplace level of respiratory protection that a respirator or class of respirators is expected to provide to employees when the employer implements a continuing, effective respiratory protection program as specified by this section. |
| Atmosphere-supplying respirator means: | a respirator that supplies the respirator user with breathing air from a source independent of the ambient atmosphere, and includes supplied-air respirators (SARs) and self-contained breathing apparatus (SCBA) units. |
| Canister or cartridge means: | a container with a filter, sorbent, or catalyst, or combination of these items, which removes specific contaminants from the air passed through the container. |
| Demand respirator means: | an atmosphere-supplying respirator that admits breathing air to the facepiece only when a negative pressure is created inside the facepiece by inhalation. |
| Emergency situation means: | any occurrence such as, but not limited to, equipment failure, rupture of containers, or failure of control equipment that may or does result in an uncontrolled significant release of an airborne contaminant. |
| Employee exposure means: | exposure to a concentration of an airborne contaminant that would occur if the employee were not using respiratory protection. |
| End-of-service-life indicator (ESLI) means: | a system that warns the respirator user of the approach of the end of adequate respiratory protection, for example, that the sorbent is approaching saturation or is no longer effective. |
| Escape-only respirator means: | a respirator intended to be used only for emergency exit. |
| Filter or air purifying element means: | a component used in respirators to remove solid or liquid aerosols from the inspired air. |
| Filtering facepiece: | (dust mask) means a negative pressure particulate respirator with a filter as an integral part of the facepiece or with the entire facepiece composed of the filtering medium. |
| Fit factor means: | a quantitative estimate of the fit of a particular respirator to a specific individual, and typically estimates the ratio of the concentration of a substance in ambient air to its concentration inside the respirator when worn. |
| Fit test means: | the use of a protocol to qualitatively or quantitatively evaluate the fit of a respirator on an individual. (See also Qualitative fit test QLFT and Quantitative fit test QNFT.) |
| Helmet means: | a rigid respiratory inlet covering that also provides head protection against impact and penetration. |
| High efficiency particulate air (HEPA) filter means: | a filter that is at least 99.97% efficient in removing monodisperse particles of 0.3 micrometers in diameter. The equivalent NIOSH 42 CFR 84 particulate filters are the N100, R100, and P100 filters. |
| Hood means: | a respiratory inlet covering that completely covers the head and neck and may also cover portions of the shoulders and torso. |
| Immediately dangerous to life or health (IDLH) means: | an atmosphere that poses an immediate threat to life, would cause irreversible adverse health effects, or would impair an individual's ability to escape from a dangerous atmosphere. |
| Interior structural firefighting means: | the physical activity of fire suppression, rescue or both, inside of buildings or enclosed structures which are involved in a fire situation beyond the incipient stage. |
| Loose-fitting facepiece means: | a respiratory inlet covering that is designed to form a partial seal with the face. |
| Maximum use concentration (MUC) means: | maximum atmospheric concentration of a hazardous substance from which an employee can be expected to be protected when wearing a respirator. |
| How can the MUC be determined mathematically? | by multiplying the assigned protection factor specified for a respirator by the required OSHA permissible exposure limit, short-term exposure limit, or ceiling limit. |
| Negative pressure respirator (tight fitting) means: | a respirator in which the air pressure inside the facepiece is negative during inhalation with respect to the ambient air pressure outside the respirator. |
| Oxygen deficient atmosphere means: | an atmosphere with an oxygen content below 19.5% by volume. |
| Physician or other licensed health care professional (PLHCP) means: | an individual whose legally permitted scope of practice allows him or her to independently provide, or be delegated the responsibility to provide, some or all of the health care services required by paragraph (e) of this section. |
| Positive pressure respirator means: | a respirator in which the pressure inside the respiratory inlet covering exceeds the ambient air pressure outside the respirator. |
| Powered air-purifying respirator (PAPR) means: | an air-purifying respirator that uses a blower to force the ambient air through air-purifying elements to the inlet covering. |
| Pressure demand respirator means: | a positive pressure atmosphere-supplying respirator that admits breathing air to the facepiece when the positive pressure is reduced inside the facepiece by inhalation. |
| Qualitative fit test (QLFT) means: | a pass/fail fit test to assess the adequacy of respirator fit that relies on the individual's response to the test agent. |
| Quantitative fit test (QNFT) means: | an assessment of the adequacy of respirator fit by numerically measuring the amount of leakage into the respirator. |
| Respiratory inlet covering means: | that portion of a respirator that forms the protective barrier between the user's respiratory tract and an air-purifying device or breathing air source, or both. It may be a facepiece, helmet, hood, suit, or a mouthpiece respirator with nose clamp. |
| Self-contained breathing apparatus (SCBA): | means an atmosphere-supplying respirator for which the breathing air source is designed to be carried by the user. |
| Service life means: | the period of time that a respirator, filter or sorbent, or other respiratory equipment provides adequate protection to the wearer. |
| Supplied-air respirator (SAR) or airline respirator means: | an atmosphere-supplying respirator for which the source of breathing air is not designed to be carried by the user. |
| Tight-fitting facepiece means: | a respiratory inlet covering that forms a complete seal with the face. |
| User seal check means: | an action conducted by the respirator user to determine if the respirator is properly seated to the face. |
| In addition, the employer must establish and implement those elements of a written respiratory protection program necessary to ensure that any employee using a respirator voluntarily is what? | medically able to use that respirator, and that the respirator is cleaned, stored, and maintained so that its use does not present a health hazard to the user. |
| The employer shall designate a program administrator. They must be: | qualified by appropriate training or experience that is commensurate with the complexity of the program to administer or oversee the respiratory protection program and conduct the required evaluations of program effectiveness. |
| T or F: The employer shall provide respirators, training, and medical evaluations at no cost to the employee. | True! |
| The employer shall select and provide an appropriate respirator based on what: | the respiratory hazard(s) to which the worker is exposed and workplace and user factors that affect respirator performance and reliability. |
