As concerns about the spread of COVID-19 grow, many employees working in essential businesses have sought to provide or require some form of respirator, face mask, or face covering for employees. Now, the CDC and White House are recommending that everyone wear some form of face covering any time in public to help reduce community spread of COVID-19. So, it is important to be aware of the OSHA guidelines and obligations regarding respirators and face coverings in the workplace. Depending on the type of face mask used, and whether it is required by the employer or permitted for voluntary use, there are certain requirements that employers must follow under OSHA’s respiratory protection standard, 29 C.F.R. 1910.134 and perhaps by other regulatory requirements.
As a starting point, let’s level-set the type of equipment we are talking about. N95 masks, although they are called masks and look like masks, are actually considered by OSHA to be respirators. Of course, anything more substantial than an N95 mask, such as half or full face tight-fitting face pieces with a filtering medium, are also considered by OSHA to be respirators. That type of equipment, whether it is required by the employer or permitted for voluntary use, triggers some requirements of OSHA’s respiratory protection standard that we will discuss below. Simple paper or cloth masks, like dental or non-N95 surgical masks, on the other hand, are not considered to be respirators, and do not trigger any requirements under 1910.134.
OSHA’s respiratory protection standard provides that a respirator shall be provided to each employee when such equipment is necessary to protect the health of such employee; i.e., if there are exposures to chemicals or other hazardous agents above permissible exposure limits. If a respirator is necessary because of exposure levels or simply because an employer mandates employees wear respirators, the employer must establish a written respiratory protection program that includes numerous elements such as fit testing, medical evaluations, procedures for proper use, storage and cleaning, and training.
OSHA’s initial Guidance for COVID-19 in the Workplace described four exposure risk categories (lower, medium, high, and very high) that workplaces and job tasks fall into, and the safety precautions that should be considered for each risk level, including what personal protective equipment (“PPE”) may be appropriate. The majority of workplaces, other than healthcare workers and those with regular close contact with known or suspected COVID-19 patients, fall into the lower or medium risk category. As of today, neither OSHA nor the CDC has issued guidance indicating that N95 respirators, or any other device considered to be a respirator, is required in lower- and medium-risk workplaces to protect employees from exposures to COVID-19.
However, that does not answer the question about what, if any, regulatory requirements there are if employers permit employees to voluntarily use N95s or other negative pressure filtering facepieces. OSHA most succinctly addressed which parts of 1910.134 apply to the voluntary use of N95 masks in a 2009 Interpretation Letter with this statement:
“If respiratory protection is not required and the employer did not advise the employee to use [an N95 dust mask], but the employee requested to use a dust mask, it would be considered voluntary use. Under these conditions, there would be no requirement to develop a written respiratory protection program; however, the employer would be responsible for providing the employee with a copy of Appendix D of 1910.134[, which outlines information for employees using respirators when not required under the standard].”
The voluntary use of N95 masks by employees does not require Continue reading
