Per-and polyfluoroalkyl substances (PFAS) are a class of over 4,700 fluorinated compounds used in industry and consumer products. Studies have highlighted use of aqueous film-forming foams (AFFFs) as an exposure source for firefighters, but little is known about PFAS occurrence inside fire stations, where firefighters spend most of their shifts. In this study, we aimed to characterize PFAS concentrations and sources inside fire stations. We measured 24 PFAS (using LC-MS/MS) and total fluorine (using particle-induced gamma ray emission) in dust from multiple rooms of 15 Massachusetts stations, many of which (60%) no longer use PFAS-containing AFFF at all and the rest of which only use it very rarely. Compared to station living rooms, turnout gear locker rooms had higher dust levels of total fluorine (p<0.0001) and three PFAS: perfluorohexanoate (PFHxA), perfluoroheptanoate (PFHpA), and perfluorodecanoate (PFDoDA) (p<0.05). These PFAS were also found on six wipes of station turnout gear. By contrast, the dominant PFAS in living rooms was N-ethyl perfluorooctane sulfonamidoacetic acid (N-MeFOSAA), a precursor to perfluorooctane sulfonate (PFOS) that still persists despite phase-outs almost two decades ago. The Σ 24 PFAS accounted for less than 2% of fluorine in dust (n=39), suggesting the potential presence of unknown PFAS. Turnout gear may be an important PFAS source in stations due to intentional additives and/or contamination from firefighting activities.Users may view, print, copy, and download text and data-mine the content in such documents, for the purposes of academic research, subject always to the full Conditions of use:

We aimed to describe coronavirus disease 2019 (COVID-19) deaths among first responders early in the COVID-19 pandemic. We used media reports to gather timely information about COVID-19–related deaths among first responders during March 30–April 30, 2020, and evaluated the sensitivity of media scanning compared with traditional surveillance. We abstracted information about demographic characteristics, occupation, underlying conditions, and exposure source. Twelve of 19 US public health jurisdictions with data on reported deaths provided verification, and 7 jurisdictions reported whether additional deaths had occurred; we calculated the sensitivity of media scanning among these 7 jurisdictions. We identified 97 COVID-19–related first-responder deaths during the study period through media and jurisdiction reports. Participating jurisdictions reported 5 deaths not reported by the media. Sixty-six decedents worked in law enforcement, and 31 decedents worked in fire/emergency medical services. Media reports rarely noted underlying conditions. The media scan sensitivity was 88% (95% CI, 73%-96%) in the subset of 7 jurisdictions. Media reports demonstrated high sensitivity in documenting COVID-19–related deaths among first responders; however, information on risk factors was scarce. Routine collection of data on industry and occupation could improve understanding of COVID-19 morbidity and mortality among all workers.

What is already known about this topic? Chronic obstructive pulmonary disease (COPD) is an important cause of disability and death in the United States. Occupational exposure accounts for 10% to 15% of the total burden, but employment may also enhance health and well-being for people with COPD. What is added by this report? Massachusetts workers with COPD were more likely than those without COPD to report indicators of poor physical and mental health. Distribution by occupation differed between the two groups. What are the implications for public health practice? Findings suggest that workplace interventions that support and retain workers with COPD may be needed.

Purpose Sharps injuries are a particularly concerning occupational hazard faced by physicians and are largely preventable. This study compared the proportion and rate of sharps injuries among medical trainees with those among attending physicians by sharps injury characteristics. Method The authors used data reported to the Massachusetts Sharps Injury Surveillance System from 2002–2018. Sharps injury characteristics examined were department where injury occurred, device, purpose or procedure for which device was used or intended, presence of sharps injury prevention feature, who was holding the device, and how and when the injury occurred. Global chi-square was used to assess differences in the percent distribution of sharps injury characteristics between physician groups. Joinpoint regression was used to evaluate trends in injury rates among trainees and attendings. Results From 2002–2018, 17,565 sharps injuries among physicians were reported to the surveillance system, 10,525 of which occurred among trainees. For attendings and trainees combined, sharps injuries occurred most in operating and procedure rooms and most often involved suture needles. Significant differences in sharps injuries were found between trainees and attendings with respect to department, device, and intended purpose or procedure. Sharps without engineered sharps injury protections accounted for approximately 4.4 times as many injuries (13,355, 76.0%) as those with protections (3,008, 17.1%). Among trainees, sharps injuries were highest in the first quarter of the academic year and decreased over time, while sharps injuries among attendings had a very slight, significant increase. Conclusions Sharps injuries are an ongoing occupational hazard faced by physicians, particularly during clinical training. Further research is needed to elucidate the etiology of the observed injury patterns during the academic year. Medical training programs need to implement a multipronged approach to prevent sharps injuries, including increased use of devices with sharps injury prevention features and robust training on safe handling of sharps.
