Respirators: Use in the HospitalTerry [email protected] 29, 2010
Objectives:
Become familiar with the DOSH regulations.
Emphasis on Filtering Facepiece Respirators
Respirators: The Standard Chapter WAC 296-842
Printed Copy
Online at www.lni.wa.gov
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
Filtering FacepieceThroughout Hospital-
Comfort Voluntary
Half-Face with Formaldehyde/Organ
ic Vapor Cartridge
Specimen Handling- Formaldehyde
Required
PAPR with HEPA Cartridge
Isolation Rooms- TB, H1N1
Required
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: Use & Removal 296-842-18005
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)
Contact your local L&I office and ask for the consultation supervisor for help with this and other DOSH requirements.
