13. NIOSH Unlike its counterpart, the Occupational Safety and Health Administration, NIOSH is not a regulatory agency. It does not issue safety and health standards that are enforceable under US law. Rather, NIOSH's authority under the Occupational Safety and Health Act [29 CFR § 671] is to "develop recommendations for health and safety standards", to "develop information on safe levels of exposure to toxic materials and harmful physical agents and substances," and to "conduct research on new safety and health problems."

14. Oxygen Atmosphere Parameters As per OSHA • Oxygen Deficient – below 19.5 % • Impaired thinking and attention • 14% abnormal fatigue, poor judgment • 12% nausea/vomiting • 10% convulsions, death • Oxygen Enriched – 23.5 % and above creating afire hazard

15. Permissible Practice • Feasible engineering controls such as enclosures, confinement of operations, ventilation, or substitution of less toxic materials • If these controls are not feasible, or while they are being instituted, appropriate respirators shall be used pursuant to this standard

16. Permissible Practice • Employer shall provide respirators, when • necessary, which are applicable and • suitable for the purpose intended • Employer shall be responsible for • establishment and maintenance of a • respirator program.

17. Permissible Practice 1910.134(a)(1) In the control of those occupational diseases caused by breathing air contaminated with harmful dusts, fogs, fumes, mists, gases, smokes, sprays, or vapors, the primary objective shall be to prevent atmospheric contamination. This shall be accomplished as far as feasible by accepted engineering control measures (for example, enclosure or confinement of the operation, general and local ventilation, and substitution of less toxic materials). When effective engineering controls are not feasible, or while they are being instituted, appropriate respirators shall be used pursuant to this section.

18. Permissible Practice 1910.134(a)(2) Respirators shall be provided by the employer when such equipment is necessary to protect the health of the employee. The employer shall provide the respirators which are applicable and suitable for the purpose intended. The employer shall be responsible for the establishment and maintenance of a respiratory protection program which shall include the requirements outlined in paragraph (c) of this section.

19. Employee Exposure “Exposure to a concentration of an airborne contaminant that would occur if the employee were not using respiratory protection.”

20. Employee Exposure Various forms of airborne contaminant, such as dust, mist, gas, radiological or biological agent should always be a considered

21. Respiratory Inlet Covering • The 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 • May be a face piece, helmet, hood, suit, or a mouthpiece respirator with nose clamp

22. Tight –Fitting Face Pieces Quarter Mask Half Mask Mouthpiece/Nose Clamp (no fit test required) Full Face Piece

23. Loose-Fitting Coverings Helmet Hood Loose-Fitting Face Piece Full Body Suit

24. FILTERS A component used in respirators to remove solid or liquid aerosols from the inspired air. Also called air purifying element.

25. Canister or Cartridge 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. Must be labeled/color coded with NIOSH approved label

26. Scott 80557-01 cartridge AM - Ammonia CD - Chlorine Dioxide CL - Chlorine FM - Formaldehyde MA - Methylamine MV - Mercury Vapor OV - Organic Vapor SD - Sulfur Dioxide HC - Hydrogen Chloride HF - Hydrogen Fluoride HS - Hydrogen Sulfide (escape only) NM-TF1 carries in stock the Scott 80557-01 40mm cartridge filter. This cartridge protects against chemicals noted on the left

27. End-of-Service-Life Indicator (ESLI) A system that warns the user of the approach of the end of adequate respiratory protection; e.g., the sorbent is approaching saturation or is no longer effective.

28. Classes of Non-powered Air-Purifying Particulate Filters • There are ten classes of NIOSH-approved particulate • filtering respirators available. 95% is the minimal • level of filtration approved by NIOSH. • The N, R and P designations refer to the filter's oil • resistance • Of these classes N, R, P there are 3 levels of filter • efficiency, each with 3 categories of resistance • to filter efficiency degradation due to presence • of oil aerosols • NRP • 100 100 99 99 99 95 95 95

29. Filter Class Description • N95, N99, N100 Filters at least 95%, 99%, 99.97% • of airborne particles. Not resistant to oil. • R95, R99, R100 Filters at least 95%, 99%, 99.97% • of airborne particles. Somewhat resistant to oil. • P95, P99, P100 Filters at least 95%, 99%, 99.97% • of airborne particles. Strongly resistant to oil. • HE (High Efficiency Particulate Air) Filters at least • 99.97% of airborne particles. For use on PAPRs. • PAPRs use only HE filters. Can be used with a Scott • AV3000 along with 40mm CBRN rated adapter

30. High Efficiency Filters • Filter that is at least 99.97% efficient in removing monodisperse particles of 0.3 micrometers in diameter.(HEPA filter per NIOSH 30 CFR 11) • Equivalent NIOSH 42 CFR 84 particulate filters are the N100, R100, and P100 filters.

31. Examples of airborne Particles, Gases • Airborne contaminants can be gases, vapors, or aerosols (small solid and liquid particles). • Dust, asbestos, silica and silicates, synthetic vitreous • fibers (SVF) or "fiberglass" , construction material • Bio-aerosols airborne particles that are living • (bacteria, viruses and fungi) • Chemical warfare agents: nerve, blood, blister, and • choking agents. Most biological are aerosols, whereas • most chemical warfare agents are gaseous. • Mold • Chemical gases • Off gassing

32. Effective Use of Respirators • For emergency response • At hazardous waste site operations • When other controls are • inadequate • When other controls are not • feasible

33. Employee Effectiveness The use of respiratory protection limits the effectiveness of the employee by 33.33 percent.

34. Types of Respiratory Protection • Atmosphere supplying • Self-contained breathing apparatus (SCBA) • Airline respirators • Air purifying • Gas and vapor • Particulate • Combination

35. Filtering Face piece(Dust Mask) • N95 face masks represent a good choice when you want to • protect yourself from airborne particles, dust, allergens, • pollen and so on. • N95 masks are approved by NIOSH and they meet the • requirements of CDC. • They are recommended by NIOSH and meet CDC guidelines • as they filter 95% of the air. Two things you should know • about them: they don’t provide air and they are not • resistant to oil

36. Filtering Face piece(Dust Mask) • N95 should be kept in deployment bag • Negative pressure particulate filter

37. Air-Purifying Respirator (APR) Air-purifying respirators can remove contaminants in the air that you breathe by filtering out particulates (e.g., dusts, metal fumes, mists, etc.). Other APRs purify air by adsorbing gases or vapors on a sorbent (adsorbing material) in a cartridge or canister. They are tight-fitting and are available in several forms

38. Air-Purifying Respirator (APR) • Utilizes filter, cartridge or canister • Ambient air passes through element

41. Powered Air-Purifying Respirator (PAPR) The purpose of this type of respirator is to take air that is contaminated with one or more types of pollutants, remove a sufficient quantity of those pollutants and then supply the air to the user. There are different units for different environments. The units consist of a powered fan which forces incoming air through one or more filters for delivery to the user for breathing. The fan and filters may be carried by the user or with some units that the air is fed to the user via tubing while the fan and filters are remotely mounted.

42. Powered Air-Purifying Respirator (PAPR) Uses a blower to force the ambient air through air-purifying elements to the inlet covering.

43. Powered Air-Purifying Respirator (PAPR)Scott Safety C420 Plus PAPR The Scott Safety C420 Plus PAPR can be used for CBRN and non-CBRN applications. It is ideal for fire departments, law enforcement and federal first responders for protection against CBRN related incidents. The C420 PLUS PAPR is NIOSH CBRN approved when used with the AV3000 (SureSeal version), and CBRN Cap-1 canister. The blower provides a cooling effect that extends user wear times in humid environments and long-duration operations, such as decontamination or rescue. It also keeps the facepiece from fogging. Decontamination is made easy with detachable parts that can be cleaned according to the situation encountered.
