3
Why respiratory protection is necessary
Air contaminants/hazardous atmospheres come from a variety of sources•Dusts•Aerosol mists•Metal fumes
4
Why respiratory protection is necessary
Air contaminants/hazardous atmospheres come from a variety of sources•Evaporated vapors•Released gases•Oxygen-deficient atmospheres
5
Why respiratory protection is necessary
Many operations generate air contaminants•Filling bins with flour•Degreasing metal parts•Spraying operations•Welding
6
Why respiratory protection is necessary
Find out how much contaminant is in the air Test the air to find out what the exposures are
7
Why respiratory protection is necessary
If results show an overexposure, take steps to control the hazard•Engineering controls•Administrative controls•PPE
8
Respirator types
Atmosphere-supplying•Supplied air•Self-contained breathing apparatus (SCBA)•Demand•Positive pressure•Escape-only
9
Respirator types
Air-purifying•Filter•Canister or cartridge
10
Respirator types
Air-purifying•Negative pressure•Powered air-purifying
11
Fit, usage, and maintenance
Employees must pass a fit test•Quantitative fit (Irritant smell)•Qualitative fit (porta-count)
Use the respirator as it was designed
12
Fit, usage, and maintenance
Follow operating instructions If respirators are used to enter an IDLH
atmosphere:•one trained, rescue-equipped employee must remain
outside•an attendant must maintain communication contact• (ESD 101 School Program NEVER allows employees
to enter into IDLH atmospheres)
13
Fit, usage, and maintenance
During interior structural firefighting:•at least 2 employees with SCBA must enter
together and stay in contact with each other•at least two people trained and equipped for
rescue must remain outside• (ESD 101 School Program NEVER allows
employees to engage in firefighting activities)
14
Fit, usage, and maintenance
A dirty, inoperative respirator will not protect you
15
Inspection, donning, doffing respirators
Inspect respirators before each use and during cleaning
Inspect SCBAs monthly and keep cylinders fully charged
(ESD 101 School Program NEVER allows employees to use SCBA respirators)
16
Inspection, donning, doffing respirators
Emergency-use respirators:• inspect monthly• tags must show inspection results
Follow manufacturer’s instructions for donning/doffing equipment
(ESD 101 School Program NEVER allows employees to use emergency-use respirators)
17
Inspection, donning, doffing respirators
Perform seal checks after donning respirator•Positive pressure test•Negative pressure test•Review Appendix B-1 (WAC 296-62-070)
Never enter a work area without a good respirator seal
18
Cleaning, maintenance, and storage
Respirators must be cleaned to remove contaminants/prevent irritation
Shared respirators must be cleaned before each use
(School administrators and/or managers assign individual-use respirators to employees who are authorized for respirator use)
19
Cleaning, maintenance, and storage
Emergency-use respirators must be cleaned after each use
Review Appendix B-2 (WAC 296-62-070) for cleaning/disinfecting instructions
Only use manufacturer’s replacement parts

Responding to Emergencies
If the respirator malfunctions, immediately leave the work area
Activate auxiliary self-contained air supply (ESD 101 School Program does not use auxiliary air
supply since no self-contained respirators are utilized in the program)
22
Responding to Emergencies
If a sudden hazardous release occurs, don emergency escape-only respirators as you exit the area
(ESD 101 School Program does not use emergency escape-only respirators since no self-contained respirators are utilized in the program)
23
Responding to Emergencies
Some employees must be trained and authorized to respond to emergency situations (Not in ESD 101 School Program)•Confined space rescue•Release of hazardous chemicals• Interior structure firefighting• (SST Program NEVER allows employees to enter
into IDLH atmospheres)
24
