Guidance for the Selection and Use of Facemasks and
Respirators
Materials referenced from CDC, FDA, NIOSH and OSHA
![Page 2: Guidance for the Selection and Use of Facemasks and Respirators Materials referenced from CDC, FDA, NIOSH and OSHA.](https://reader036.fdocuments.us/reader036/viewer/2022070412/56649e765503460f94b7791f/html5/thumbnails/2.jpg)
Current CDC & OSHA Recommendations
• Healthcare Settings– Workers:
• Standard and Contact Precautions + eye protection for direct patient care workers [NIOSH-approved N95 respirator]
• N95 respirators for other staff in close contact with patients
– Patients with ILI symptoms• Facemasks
• Community Settings – None (facemasks as needed)
• Part of overall Infection Control Practices

Masks vs. Respirators • Facemasks
– Designed to cover the mouth and nose loosely – Usually strapped behind the head – Made of soft materials and are comfortable to wear– Provide only minimal protection from respirable
particles
![Page 4: Guidance for the Selection and Use of Facemasks and Respirators Materials referenced from CDC, FDA, NIOSH and OSHA.](https://reader036.fdocuments.us/reader036/viewer/2022070412/56649e765503460f94b7791f/html5/thumbnails/4.jpg)
Masks vs. Respirators• Respirators
– Fits tightly to cover the nose and mouth– Provide protection against inhalation of small
and large airborne particles
N95- Filtering FacepieceElastomeric PAPR: Powered Air
Purifying Resp.

Rating of Protection Offered
• Facemasks• Can protect from large particles from
splashes• Not rated for protection from
small inhalable particles
• Respirators– Rated by oil-resistance and filter efficiency
• N95: Not oil resistant, and 95% efficient against small inhalable particles
• Elastomeric and PAPRs: typically HEPA (high-efficiency particulate air): 99.97% efficient

Regulations & Recommendations for Respirators
• OSHA issues workplace health and safety regulations. When required, employers must:– Provide appropriate respirators
– Medical evaluation
– Fit testing
– Training
– Ensure workers do fit checking before each use
• CDC recommends when, what and how to use PPE

Current CDC Recommendations for Pandemic Influenza
• Healthcare – Direct Patient Care Workers– NIOSH-certified N95 or higher recommended for use
during high-risk activities including:• Aerosol-generating procedures
• Resuscitation of confirmed or suspected influenza case
• Providing direct care to confirmed or suspected influenza-associated
– Only slight revision from seasonal influenza guidance
• Part of overall Infection Control Practices
![Page 8: Guidance for the Selection and Use of Facemasks and Respirators Materials referenced from CDC, FDA, NIOSH and OSHA.](https://reader036.fdocuments.us/reader036/viewer/2022070412/56649e765503460f94b7791f/html5/thumbnails/8.jpg)
Current CDC Recommendationsfor Pandemic Influenza
• Healthcare Patients – Facemasks should be offered
• as part of a respiratory hygiene/cough etiquette strategy,
• to patients who present for care with coughing or have other ILI symptoms
• Close contacts and those with travel history• worn until the cause of symptoms is determined not an
infectious agent that requires isolation or patient has been appropriately isolated
![Page 9: Guidance for the Selection and Use of Facemasks and Respirators Materials referenced from CDC, FDA, NIOSH and OSHA.](https://reader036.fdocuments.us/reader036/viewer/2022070412/56649e765503460f94b7791f/html5/thumbnails/9.jpg)
Current CDC Recommendations• Community Settings
– Facemask use in proximity to a symptomatic person may not effectively limit transmission
– Emphasis should be on• cough etiquette and • staying home• facemask use if near confirmed cases• If symptomatic persons cannot stay home, consideration should
be given to having them wear a facemask in public
– No recommendation for use by asymptomatic persons, including those at high risk for complications

OSHA Occupational Risk Categories
• Very High: Healthcare workers performing aerosol-generating procedures or collecting respiratory tract specimens from known or suspected cases
• High: Healthcare workers and support staff exposed to known or suspected cases (including EMTs)
• Medium: high-frequency contact with the public
• Low: minimal occupational contact with the public
![Page 11: Guidance for the Selection and Use of Facemasks and Respirators Materials referenced from CDC, FDA, NIOSH and OSHA.](https://reader036.fdocuments.us/reader036/viewer/2022070412/56649e765503460f94b7791f/html5/thumbnails/11.jpg)
Recommendations for OSHA Occ. Risk Categories
• Very High:– Re-usable Elastomeric Respirator or PAPR or N95
• High:– Workers: N95, elastomeric respirator or PAPR– Patients: Facemasks
• Medium:– Facemasks
• Low:– None

OSHA Guidance on Respirator Stockpiling
![Page 13: Guidance for the Selection and Use of Facemasks and Respirators Materials referenced from CDC, FDA, NIOSH and OSHA.](https://reader036.fdocuments.us/reader036/viewer/2022070412/56649e765503460f94b7791f/html5/thumbnails/13.jpg)
OSHA Guidance on Facemask Stockpiling
Occupational setting Facemasks needed
Healthcare
Hospital (inpatient) 2 per patient per day
Essential visitors 3 per visitor per day
Emergency Rooms 1 per ill person
Outpatient office/clinic 2 per patient visit
Emergency medical services 1 per ill person
![Page 14: Guidance for the Selection and Use of Facemasks and Respirators Materials referenced from CDC, FDA, NIOSH and OSHA.](https://reader036.fdocuments.us/reader036/viewer/2022070412/56649e765503460f94b7791f/html5/thumbnails/14.jpg)
Respirator Re-Use• Elastomeric respirators and PAPRs
– Designed for re-use following proper cleaning– Filter cartridges can last long periods
• N95 Respirators– Designed for one time use; Not cleanable– Can be re-used in not grossly contaminated
• Protect with a facemask or face shield• Single-user
• Increased risk of contamination of hands and face
![Page 15: Guidance for the Selection and Use of Facemasks and Respirators Materials referenced from CDC, FDA, NIOSH and OSHA.](https://reader036.fdocuments.us/reader036/viewer/2022070412/56649e765503460f94b7791f/html5/thumbnails/15.jpg)
Community Use of N95 Respirators• FDA has cleared the following N95 respirators
for use by the general public• 3M™ Particulate Respirator 8670F• 3M™ Particulate Respirator 8612F• Pasture™ F550G Respirator• Pasture™ A520G Respirator
– N95 respirators are not designed for people with facial hair or children.
– People with chronic respiratory, cardiac, or other medical conditions that make it harder to breathe should check with their healthcare
