6 FAQs regarding the use of masks in the workplace from OSHA

The U.S. Department of Labor’s Occupational Safety and Health Administration (OSHA) has published a series of frequently asked questions and answers regarding the use of masks in the workplace.
“As our economy reopens for business, millions of Americans will be wearing masks in their workplace for the first time,” said Principal Deputy Assistant Secretary for Occupational Safety and Health Loren Sweatt. “OSHA is ready to help workers and employers understand how to properly use masks so they can stay safe and healthy in the workplace.”
Below are the six FAQs published by OSHA:
1. What are the key differences between cloth face coverings, surgical masks, and respirators?
Cloth face coverings: May be commercially produced or improvised (i.e., homemade) garments, scarves, bandanas, or items made from t-shirts or other fabrics. Are worn in public over the nose and mouth to contain the wearer's potentially infectious respiratory droplets produced when an infected person coughs, sneezes, or talks and to limit the spread of SARS-CoV-2, the virus that causes Coronavirus Disease 2019 (COVID-19), to others. Are not considered personal protective equipment (PPE). Will not protect the wearer against airborne transmissible infectious agents due to loose fit and lack of seal or inadequate filtration. Are not appropriate substitutes for PPE such as respirators (e.g., N95 respirators) or medical face masks (e.g., surgical masks) in workplaces where respirators or face masks are recommended or required to protect the wearer. May be used by almost any worker, although those who have trouble breathing or are otherwise unable to put on or remove a mask without assistance should not wear one. May be disposable or reusable after proper washing.
Surgical masks: Are typically cleared by the U.S. Food and Drug Administration as medical devices (though not all devices that look like surgical masks are actually medical-grade, cleared devices). Are used to protect workers against splashes and sprays (i.e., droplets) containing potentially infectious materials. In this capacity, surgical masks are considered PPE. Under OSHA's PPE standard (29 CFR 1910.132), employers must provide any necessary PPE at no-cost to workers. May also be worn to contain the wearer's respiratory droplets (e.g., healthcare workers, such as surgeons, wear them to avoid contaminating surgical sites, and dentists and dental hygienists wear them to protect patients). Should be placed on sick individuals to prevent the transmission of respiratory infections that spread by large droplets. Will not protect the wearer against airborne transmissible infectious agents due to loose fit and lack of seal or inadequate filtration. May be used by almost anyone. Should be properly disposed of after use.
Respirators (e.g., filtering facepieces): Are used to prevent workers from inhaling small particles, including airborne transmissible or aerosolized infectious agents. Need proper filter material (e.g., N95 or better) and, other than for loose-fitting powered, air purifying respirators (PAPRs), tight fit (to prevent air leaks). Require proper training, fit testing, availability of appropriate medical evaluations and monitoring, cleaning, and oversight by a knowledgeable staff member. When necessary to protect workers, require a respiratory protection program that is compliant with OSHA's Respiratory Protection standard (29 CFR 1910.134). OSHA consultation staff can assist with understanding respiratory protection requirements. FFRs may be used voluntarily, if permitted by the employer. If an employer permits voluntary use of FFRs, employees must receive the information contained in Appendix D of OSHA's Respiratory Protection standard (29 CFR 1910.134).
2. Are employers required to provide cloth face coverings to workers?
Cloth face coverings are not considered personal protective equipment (PPE) and are not intended to be used when workers need PPE for protection against exposure to occupational hazards. As such, OSHA's PPE standards do not require employers to provide them.
3. Should workers wear a cloth face covering while at work, in accordance with the Centers for Disease Control and Prevention recommendation for all people to do so when in public?
OSHA generally recommends that employers encourage workers to wear face coverings at work. Face coverings are intended to prevent wearers who have Coronavirus Disease 2019 (COVID-19) without knowing it (i.e., those who are asymptomatic or pre-symptomatic) from spreading potentially infectious respiratory droplets to others. This is known as source control.
Consistent with the Centers for Disease Control and Prevention (CDC) recommendation for all people to wear cloth face coverings when in public and around other people, wearing cloth face coverings, if appropriate for the work environment and job tasks, conserves other types of personal protective equipment (PPE), such as surgical masks, for healthcare settings where such equipment is needed most.
4. If workers wear cloth face coverings, do employers still need to ensure social distancing measures in the workplace?
Yes. Cloth face coverings are not a substitute for social distancing measures.
5. If I wear a reusable cloth face covering, how should I keep it clean?
CDC provides guidance on washing face coverings. OSHA suggests following those recommendations, and always washing or discarding cloth face coverings that are visibly soiled.
6. Are surgical masks or cloth face coverings acceptable respiratory protection in the construction industry, when respirators would be needed but are not available because of the COVID-19 pandemic?
No. Employers must not use surgical masks or cloth face coverings when respirators are needed.
