Objectives:

Become familiar with the DOSH regulations.

Emphasis on Filtering Facepiece Respirators

Respirators: The Standard Chapter WAC 296-842

Workplace Safety & Health Rules CD

Respirators: Scope 296-842-100Evaluate the respiratory

hazards at the worksite.

Compare results to the PEL table in WAC 296-841, Airborne Contaminates.

Other airborne hazard such as biological hazards.

Respirators: Program Administrator

Does not require a certification or formal training

Overall responsibility for the program

Will oversee the program development

Coordinate implementation

Conduct required evaluations of program effectiveness

Respirators: Voluntary Use 296-842-110

Voluntary use of filtering facepiece-Train on Table 2 contents

Voluntary use of all other respirators– Train on Table 2 – Provide for medical evaluation – Written program for specific requirements – Program administrator

Filtering Facepiece Cartridge Respirator

Respirators: Written Program 296-842-12005

Written program is to be worksite specific

Detailed so future administrators can implement

Cover all applicable elements in Table 3 Updated when changes take place Available to employees and others

Respirators: Written Program 296-842-12005Specific Items from Table 3: A list specifying the appropriate respirator for

each respiratory hazard in your workplace

Respirators: Written Program 296-842-12005

Specific Items from Table 3: APRs used for gas or vapor contaminates

must have:– End-of-service-life-indicator (ESLI) – Or cartridge change out schedule including

information relied upon to calculate itQ: When do you change a dust filter?A: When there is resistance to breathing.

Respirators: Selection 296-842-13005

So what kind of respirator do I need?

What do the Letters and Numbers Mean?

Numbers designate expected filter efficiency to remove particles:

95 = 95% efficiency

99 = 99% efficiency

100 = 100% efficiency

100% efficiency = HEPA ratingHEPA = High Efficiency Particulate Air filter

Use Restrictions for N, R, and P Respirator Categories

Use When

N No oil is present in the air

R Oil is present, but only for a single shift or 8 hours of continuous or intermittent use.

Note:Reuse beyond a single shift or 8 hours is not recommended.

P Oil is present, but follow the manufacturer’s time use limitations if you want to reuse these.

N, R, P, 95, 99, 100 Designation

Are These Considered Respirators?

No.

Does not Seal to the Face Does Seal to the Face

Respirators: Selection 296-842-13005

Respirators selected are to be certified by the National Institute for Occupational Safety and Health (NIOSH).

NIOSH certification is voided when:

• Users don’t follow the approval label’s use specifications, including listed cautions and limitations.

• Respirator parts used aren’t listed under the respirator assembly’s TC number.

Other Respirator Options

Respirators: Medical Evals 296-842-14005 Clears employees to wear a respirator Required prior to fit-testing or respirator use Identify a LHCP to perform medical evaluations

– By questionnaire– By physical exam

Follow up dependant upon LHCP, changes in respirator use, or employee difficulties

Medical Evaluations are not required annually

Respirators: Fit Testing 296-842-15005

Fit-test the same make, model and size to be used

All fit-tests require the employee to perform fit test exercises as listed in Table 19.

Exercises stress facepiece seal Fit testing is required at least annually.

Purpose of Fit Testing

Respirators: Fit Testing 296-842-15005There are two types

of fit testing:

- Qualitative

-Quantitative

Fit-Tests Types

Qualitative Fit-Test Procedures:

•Isoamyl Acetate vapor (banana oil- not for filtering facepiece)

•Saccharine aerosol

•Bitrex aerosol

•Irritant Smoke (HEPA Only)

Fit-Tests Types

Quantitative Fit-Test Procedures:

•Ambient aerosol condensation nuclei counter (Portacount)

•Controlled negative pressure (CNP)

•Generated aerosol

Respirators: Training 296-842-16005 Initially, before use begins Periodically, within 12 months of

previous training (annually) Additionally

– When employees haven’t retained knowledge

– Changes in worksite – Changes in respirator type make

previous training out of date.

Respirators: Maintenance 296-842-17005

Clean and Disinfect:

As often as needed to keep it clean and functional and to prevent health hazards.

Before it is worn by another employee.

After each use for emergency respirators.

Respirators: Maintenance 296-842-17005

Respirators: Use & Removal 296-842-18005Prevent Sealing Problems with Tight-Fit Resp.

Seal Check (+,- pressure check) each time put one on

No facial hair between face and sealing surface or that interferes with valve function

No other PPE or glasses that breaks respirator seal

Leave contaminated area prior to removing respirator for any reason.

Respirators: Reqd Procedures 296-842-22005

Medical questionnaire location

Fit-Test procedures for each approved test including test exercises

Procedures for cleaning and disinfecting

Procedures for seal checking

Respirators: Reqd Procedures 296-842-22005

Q: Can an employee who has facial hair be fit tested?

A: No!!!

Prohibited under 842-22010 (6)
