Why respiratory protection is necessary

Air contaminants/hazardous atmospheres come from a variety of sources•Dusts•Aerosol mists•Metal fumes

Why respiratory protection is necessary

Air contaminants/hazardous atmospheres come from a variety of sources•Evaporated vapors•Released gases•Oxygen-deficient atmospheres

Page 5: 1/05 School Safety Training Respirators A Program Overview WISHA WAC 296-841 WAC 296-842 OSHA 29 CFR 1910.134

Why respiratory protection is necessary

Many operations generate air contaminants•Filling bins with flour•Degreasing metal parts•Spraying operations•Welding

Page 6: 1/05 School Safety Training Respirators A Program Overview WISHA WAC 296-841 WAC 296-842 OSHA 29 CFR 1910.134

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

Why respiratory protection is necessary

If results show an overexposure, take steps to control the hazard•Engineering controls•Administrative controls•PPE

Respirator types

Atmosphere-supplying•Supplied air•Self-contained breathing apparatus (SCBA)•Demand•Positive pressure•Escape-only

Respirator types

Air-purifying•Filter•Canister or cartridge

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

Page 12: 1/05 School Safety Training Respirators A Program Overview WISHA WAC 296-841 WAC 296-842 OSHA 29 CFR 1910.134

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)

Page 13: 1/05 School Safety Training Respirators A Program Overview WISHA WAC 296-841 WAC 296-842 OSHA 29 CFR 1910.134

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)

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)

Page 16: 1/05 School Safety Training Respirators A Program Overview WISHA WAC 296-841 WAC 296-842 OSHA 29 CFR 1910.134

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)

Page 17: 1/05 School Safety Training Respirators A Program Overview WISHA WAC 296-841 WAC 296-842 OSHA 29 CFR 1910.134

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

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)

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)

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)

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)
