On February 3, 2023, five train cars containing 887,400 pounds of vinyl chloride, the key building block for polyvinyl chloride (PVC) plastic, derailed and burned, setting off a major environmental health disaster that sickened area residents and first responders, killed wildlife, and contaminated East Palestine, Ohio and surrounding communities. OxyVinyls is the largest vinyl chloride monomer producer in the United States and the third-largest PVC supplier in the United States. How much of this hazardous chemical is transported every year, and how many people are put at risk? To better understand the magnitude of this hazard, we established the most likely rail routes for shipping of vinyl chloride from two OxyVinyls plants in Texas to four PVC factories in New Jersey, Illinois, and Ontario. We estimate that up to 36 million pounds of vinyl chloride travels on more than 200 rail cars across nearly 2,000 miles of US railways at any given moment. Over a year, an estimated 8,595 rail cars carry approximately 1.5 billion pounds of vinyl chloride from OxyVinyls to these plastics plants. The rail shipment of vinyl chloride to make PVC plastic puts more than three million people at risk. We estimate more than three million people live, and about 670,000 children attend more than 1500 schools, within one mile of the train route between Texas and New Jersey.

An ever-increasing number of workplaces are becoming heat-exposed due to rising temperature extremes. However, a comprehensive review of Canadian safety materials available to support workplaces in managing this critical hazard has not previously been conducted. We undertook a review and a content analysis of heat stress materials on safety-based ministry, association, and agency websites in Canada (n = 155) to identify content related to heat stress (n = 595). Each document was qualitatively analyzed using NVivo. The most dominant components identified were heat stress control measures (n = 492, 83%), training and education (n = 414, 70%), workplaces and workers at risk (n = 361, 61%), exposure limits and monitoring practices (n = 344, 58%), and emergency response and reporting (n = 249, 42%). However, the content within these programming components was highly variable. While we found that organizations across Canada provide heat stress content, there was evidence of inconsistencies and considerable gaps in the availability of material and the strategies presented to control the critical risk posed by heat.

California has a significant day laborer population, with about one-third of the total U.S. day laborer population working in the state. Day laborers, characterized by a lack of labor protections, low socioeconomic status, English illiteracy, and irregular immigration status, face numerous challenges regarding work-related injuries and limited access to healthcare. Eighty percent of day laborers are undocumented, and most do not have access to healthcare. Despite recent research growth, little is known about their experiences with work-related injuries and healthcare treatment. Our findings reveal that only 8.4% of day laborers have health insurance, and around 26% have experienced work-related injuries. This paper highlights the challenges faced by this population and emphasizes the importance of understanding their experiences to improve occupational health and safety policy. Additionally, we acknowledge the critical role of worker centers and national efforts in addressing health and safety issues among day laborers.

Over a century ago, Connecticut industry began using chrysotile asbestos. Chrysotile found a home in several factories that used it exclusively or predominantly. The occurrence of mesothelioma in 4 of those factories is the subject of this paper-2 have been reported previously and are updated here with new information; one was the subject of a prior internal corporate study that was never published; one is reported here for the first time. Twenty-four cases of mesothelioma have been identified among these workers, including several who had no known amphibole exposure. It is likely that additional cases of mesothelioma have been missed. The full scale of the hazard may never be completely known, but reports such as the present one add to the weight of evidence that chrysotile causes mesothelioma in humans and that the full extent of the epidemic is probably wider than retrospective studies have revealed. Continued vigilance is required.

This is an extended version of the speech given by Garrett Brown in accepting the Alice Hamilton Award from the Occupational Health and Safety Section of the American Public Health Association. The award recognizes the life-long contributions of individuals who have distinguished themselves through a career of hard work and dedication to improve the lives of workers. Alice Hamilton (1869-1970) was considered the founder of occupational health in the U.S. and was a tireless activist and physician who dedicated her life to improving the health and safety of workers. She was committed to science, service, and compassion.

For many women, house cleaning is an important way to participate in the labor market. In Brazil, there are 2 types of domestic workers: housekeepers have relatively secure employment and house cleaners are day laborers. The aim of this hypothesis-generating study was to describe the sociodemographic, occupational and health profile of a sample of domestic workers in Brazil. House cleaners received lower wages, had longer daily working hours and worked in a larger number of homes each week in comparison to housekeepers. About 51% of the domestic workers in this sample reported the use of pain medication and 34% reported spinal problems. Musculoskeletal symptoms were frequent in the lower back and upper limbs. Forty-seven percent reported high blood pressure. This study highlights the vulnerability of domestic workers, especially house cleaners, regarding workload, salary, and health conditions. Level of education is a contributing factor to this vulnerability.

The controversy over whether repeated head impact (RHI)-a feature of occupations including professional contact sports, military service, firefighting, and logging-can cause the neurodegenerative disease now known as CTE (chronic traumatic encephalopathy) has thrust many positive epidemiologic studies into the spotlight. Various skeptics who dispute that the relationship is strong and causal continue to raise objections to these studies and their interpretation. The arguments these skeptics use remind other observers of many past sagas of "manufactured doubt," particularly the history of attempts to cast doubt on the propensity of tobacco products to cause lung cancer. A recent article in the Journal of Science and Medicine in Sport³ complained that drawing the parallel between RHI and cigarettes is unhelpful, concluding that "the time for politically motivated analogies has now passed." This author disagrees, and explains in detail 2 scientific aspects of risk assessment and management that make the analogy apt and instructive for the future. In particular, I argue that the problem of "manufactured doubt" here is two-fold: it relies on various fallacies of reasoning discussed herein, but more importantly, it seeks to divert and delay the utilitarian imperative-while we grope toward the ever-elusive certainty, there are many low-regret actions we can and should take on the basis of persuasive signals of harm.
