29 CFR 1910.134 02/06/20 Air Contaminants Any substances that are not a normal components of breathing air (oxygen, nitrogen, etc..) The respiratory threat posed by contaminants is a function of the actual contaminant and its

concentration in the air. 02/06/20 Types Of Respiratory Protection Air-purifying Atmosphere-supplying Includes supplied air and SCBA 02/06/20 Air-purifying

Half - Mask - covers the mouth and nose and fits under the chin of the wearer. Full - Facepiece - covers the wearer from the hairline to below the chin. Provides the greatest protection to the wearer from exposure to hazardous materials as well as eye protection. 02/06/20 Cartridges Under the new respiratory protection

standard, cartridges must be changed according to: A NIOSH certified end-of-service life indicator; or Use a change schedule (manufacturers recommendations) 02/06/20 PAPR Powered Air Purifying Respirators This device uses a blower to pass contaminated air through an element

that removes the contaminants and supplies purified air to the wearer. The element may be a particulate filter, gas/ vapor cartridge, or a combination filter and cartridge. 02/06/20 Atmosphere - Supplying Respirators SCBA Self -contained Breathing

Apparatus SAR Supplied-air respirator 02/06/20 Supplied Air Respirators SAR Deliver breathing air through a supply hose connected to the wearers facepiece or enclosure. Air line respirators can not be used in

IDLH atmospheres, unless used in conjunction with an escape respirator. 02/06/20 Emergency Signals Verbal communication while wearing respirators is difficult because talking is muffled and distorted by the face mask. A set of hand signals known to all

personnel is essential for working together safely. 02/06/20 Equipment Selection Respirator Decision Logic is to ensures technical accuracy and uniformity in the selection of respirators and to provide necessary criteria to support the selection.

NIOSH Decision Logic 1-80035NIOSH 02/06/20 Warning Properties Includes odor, eye irritation, and respiratory irritation. Warning properties relying on human senses are not foolproof. Provides some indication to the wearer of possible sorbent exhaustion or of poor facepiece fit or other respirator

malfunction. 02/06/20 IDLH Immediately dangerous to life and health Conditions that pose an immediate threat to life or health Conditions that pose an immediate threat of severe exposure to contaminants

02/06/20 In establishing the IDLH concentration the following factors are considered: 1) Escape without loss of life or irreversible health effects. Thirty minutes is considered the maximum exposure time for escape. 2) Severe eye or respiratory irritation or

other reactions that would prevent escape 02/06/20 without injury. Fit Testing Fit tested with same make, model, style, and size of respirator to be used Qualitative Quantitative
