Reducing Hazardous Exposures in Dental Clinics
Dentistry is not usually considered a high-risk job. However, workers in the dental field are among those with the highest occupational risk for exposure to SARS-CoV-2, the virus that causes COVID-19. Dental personnel often work closely with patients who remove their masks for procedures. These dental procedures can produce aerosols, or sprays of liquid, from a patient’s mouth, which could expose nearby workers.
Those working in dental settings, including dental clinics and laboratories, can also face other types of exposures. Some dental personnel can perform tasks that potentially generate dusts linked to lung diseases such as pneumoconiosis and pulmonary fibrosis. A 2018 MMWR by NIOSH authors and others reported a cluster of idiopathic pulmonary fibrosis (IPF) among dental staff. IPF is a lung disease where the lungs become scarred for an unknown reason. Although no clear connection between IPF and occupational exposures was identified in this study, the cluster of IPF observed among dental personnel indicated a need to learn more about what exposures may be contributing to IPF in these workers. Both the increased risk for COVID-19 exposure and the IPF cases heighten the importance of reducing potentially hazardous exposures in dental settings.
One way of reducing hazardous exposures in dental settings is to reduce potential exposures to harmful aerosols by using engineering controls such as “source controls.” Source controls directly capture and remove aerosols before they can enter the air and be inhaled by nearby workers. In dental settings, dental evacuation systems (suction devices designed to remove fluids during treatment) can work as source controls by capturing aerosols at a patient’s mouth. However, the efficiency of different commercially available systems varies, and their effectiveness as source controls has not been extensively studied.
To work on this issue, NIOSH partnered with the West Virginia University’s School of Dentistry to learn more about the efficiency of dental evacuation systems. NIOSH recently completed a study on four such systems during simulated dental procedures. Another ongoing study is evaluating five dental evacuation systems during routine clinical procedures with patients. Results of both studies will improve our understanding of how well these systems work as aerosol exposure controls. They will also help dental clinics decide which engineering controls might best suit the needs of their practice or clinic.
Another project NIOSH researchers are working on aims to characterize ventilation systems and evaluate exposures that could possibly contribute to occupational lung disease in dental practices. They plan to conduct field studies at 30 dental clinics across different specialties and settings. Results from this project will further our understanding of ventilation designs in dental settings. It will also provide data about potentially hazardous task-specific and job-specific exposures, informing recommendations for exposure controls.
To learn more about these studies, or possibly participate in one, dental staff are encouraged to contact NIOSH. For more information, you can contact Dr. Brie Blackley at BBlackley@cdc.gov.

**Firefighters can be Exposed to Compounds Through the Skin**
Firefighters can be exposed to harmful compounds through skin absorption, even when they wear personal protective equipment (PPE), according to research published in the *International Journal of Hygiene and Environmental Health*.
When materials burn, they can release compounds, such as benzene, toluene, and naphthalene. Of these, benzene is known to cause cancer. While respiratory protection is designed to protect firefighters from breathing in compounds, firefighters can be exposed to these substances through the skin.
To study this issue, a structure was set up to train firefighters with a separate “burn” chamber where a sofa was set on fire to create smoky conditions. Study participants performed firefighting activities in the structure wearing various types of PPE, including new and laundered gear. Twenty-four firefighters participated in the study. Researchers measured levels of three compounds released in the air during fires: benzene, toluene, and naphthalene. Researchers also measured concentrations of these compounds under the firefighters’ PPE (jackets) and in their exhaled breath.
Benzene concentrations were nearly the same inside and outside of the jackets. Naphthalene and toluene concentrations were lower inside compared with outside the jackets, but these compounds still entered through PPE. Concentrations of benzene in firefighters’ exhalations increased from pre- to post-fire, even though the firefighters wore self-contained breathing apparatus (SCBA). Using SCBA should have prevented the firefighters from inhaling airborne compounds, but benzene and other compounds that get underneath their gear may be absorbed through the skin, enter the bloodstream, and then be measured in exhaled breath.
This study suggests that firefighter PPE will not protect firefighters’ skin from these three compounds. A proportion of these compounds may then be absorbed through skin. These findings help inform efforts to prevent exposures to these and other harmful compounds during firefighting.

**Gaps Identified in Workplace Resources for Opioid Use Disorder**
In the first half of 2020, about 90% of all overdose deaths in Maryland involved opioids. The same year, the Maryland Department of Health, where NIOSH supports an Occupational Safety and Health Surveillance Program, launched a study exploring the effects of opioids on employment within Maryland. The project, called Workplace PROSPER (Partnering to Reduce Opioid Stigma and Promote Employment in Recovery), aims to develop a toolkit of work-related recovery resources. The study recently appeared in *New Solutions: A Journal of Environmental and Occupational Health Policy*.
Eighty-six experts participated in information-gathering sessions and identified resources in eight key areas to include within the Maryland Workplace PROSPER toolkit. These areas included 1) supervisors and managers, 2) hiring, 3) recovery supports at work, 4) retention, 5) culture change, 6) medical system interactions, 7) tangible human resource policies, and 8) families. The researchers then compared resources in these areas to toolkits developed by seven other states and organizations to identify existing resources and potential gaps.
Although many of the resources were available in preexisting toolkits, several gaps emerged. For example, tools to support physicians when discussing opioid use disorder and workplace issues with their patients were lacking. Also absent were resources to support family members and model programs for hiring people in recovery. Next, the researchers plan to conduct surveys among employers and adults in recovery to further inform development of the toolkit.

**In Memoriam: Former HELD Director Dr. Al Munson**
It is with profound sadness that we announce the recent death of former NIOSH Health Effects Laboratory Division (HELD) Director, Albert E. Munson, Ph.D. Dr. Munson joined NIOSH in 1996 from the Medical College of Virginia, Virginia Commonwealth University, where he was a Professor of Pharmacology and Toxicology. An immunotoxicology pioneer, Dr. Munson was an internationally recognized leader in Occupational Safety and Health, conducting many important studies of the effects of chemical exposures on the immune system.
Dr. Munson was the founding director of HELD, serving in this capacity for 17 years until his retirement in 2014. He was instrumental in building the new division from its early beginnings in Morgantown, West Virginia, recruiting and standing up a laboratory with over 200 new staff in a short period of time. Throughout his years of leadership, Dr. Munson consistently brought a high level of scientific excellence to NIOSH through numerous achievements in basic and applied research. Dr. Munson was also an outstanding mentor to young investigators and public health practitioners, inspiring many to pursue careers in occupational safety and health. Read his complete obituary.

**CDC Researchers Identify New Occupational Disease Among Metalworkers**
Welder’s anthrax is a rare and deadly disease. It is defined as a pneumonia in metalworkers caused by bacteria from within the *B. cereus* group that produces anthrax toxin. A new journal article and blog post describe this newly identified occupational disease. The article is the first to report additional information on cases, describe possible infection mechanisms, and outline prevention measures that should help prevent transmission of welder’s anthrax in the workplace.
**How to Choose the Right Fatigue Detection Technology for Your Workplace**
Fatigue can reduce focus, slow reaction time, and impair decision-making skills. Because fatigue has many sources, it can be hard to detect on job sites. NIOSH published an infographic and graphics to highlight different factors for employers to consider when selecting a fatigue detection technology as part of a comprehensive safety management approach.
**Recordings Available of Occupational Exoskeletons Webinars**
NIOSH recently released seven webinar recordings related to the prevention of work-related musculoskeletal disorders to YouTube for easier access. Although the recordings are from 2019–2021, the content is still accurate and informative. You can find the webinar list with links to each on the NIOSH Musculoskeletal Health Program: Webinars webpage.
**New Strategic Foresight Webpage**
NIOSH recently posted a new webpage on  strategic foresight defined on that page as “a practice that looks ahead and asks what may be coming, how it might affect us, and what we can do today to start moving toward a preferred future outcome.” The webpage provides information about initiatives designed to promote awareness and capacity in foresight throughout the occupational safety and health community. For questions about this new webpage or the initiatives, contact the NIOSH Office of Research Integration.
**Updated Webpage for Trenching and Excavation**
NIOSH recently updated its Trenching and Excavation webpage and published an infographic to promote trench safety work practices in the construction industry.
