A coronavirus is named for the crown-like spikes on its surface that are apparent when the virus is viewed under extreme magnification. Human coronaviruses were first identified in the mid-1960s. There are four main sub-groupings of human coronaviruses: alpha, beta, gamma and delta. The gamma and delta coronaviruses do not cause known human disease.

Emergency Temporary Standard on Occupational Exposure to COVID-19

North Carolina adopted verbatim the federal OSHA's Emergency Temporary Standard for Healthcare with an effective date of July 21, 2021. North Carolina's standard was repealed in its entirety by NCDOL effective March 4, 2022. In the absence of a healthcare standard, NCDOL will enforce general standards to include; the general duty clause, personal protective equipment, and respiratory protection. Since work-related COVID-19 cases are recordable illnesses, OSHA's recordkeeping standards (Part 1904) would also apply.

What can I do to protect myself and others when transmission is on the rise?

Engineering, Administrative and Work Practice Controls.

  • Follow established work procedures for infection control. 
  • Wash hands frequently with soap and water for at least 20 seconds.
  • Avoid close contact with people that are sick.
  • Maintain a physical distance of at least 6 feet from other people.
  • Wear a cloth face covering, especially when physical distancing cannot be maintained.
  • Cover your mouth when you cough with a tissue or elbow, Throw tissue in trash, do not reuse.
  • Clean and disinfect work areas frequently. 
  • Avoid touching your eyes, nose and mouth. 
  • Employees who believe they are infected with 2019 nCoV are encouraged to self-quarantine at home to prevent infecting others.

Personal Protective Equipment. Employees in certain higher risk occupational settings are especially encouraged to use respirators that afford the level of protection of an N95 filtering facepiece respirator or better. Where respirator use is required, the employer must implement an effective respiratory protection program including, but not limited to, medical evaluation and fit testing.  In addition, use and properly maintain all provided personal protective equipment for work-related tasks having exposure(s).

What resources are available to assist employers?

Training and Outreach Services

Presentations on a variety of topics associated with exposure to 2019 nCoV are available to assist employers in training their staff. These include bloodborne pathogens, hazard communication, respiratory protection and personal protective equipment. Each of these presentations should be modified to address site-specific conditions and hazards. 

In addition, the education, training and technical assistance bureau provides free online safety and health training and outreach services (i.e., speaker's bureau requests, safety booths) upon request. 

Lastly, the NCDOL Library offers free safety and health videos (including ones on COVID-19) and related research assistance on consensus standards (i.e., ANSI, NFPA, NEC).

Safety and Health Programs

Example safety and health programs are available for employers to download and adapt to their specific conditions. Safety and health programs relative to 2019 nCoV include bloodborne pathogens exposure control plan, hazard communication program, personal protective hazard assessment and respiratory protection program.

A- Z Safety and Health Topics

More information related to the 2019 novel coronavirus can be found on the A-Z topics pages for hazard communication, personal protective equipment, bloodborne pathogens and respiratory protection.

Consultation Services

The consultative services bureau provides free and confidential onsite consultation regarding worksite safety and health hazards.
