Time to Fix the Damage of Weakened Chemical Disaster Prevention Regulations.

The Trump administration weakened regulations through changes on rules that have been improved during the Obama years. An example is the reversal in 2019 of the improvements to the U.S. Environmental Protection Agency Risk Management Program, Chemical Disaster Prevention Rule. In 2013 a catastrophic explosion of ammonium nitrate in West, Texas, provided the impetus to improve the original regulations after an investigation of its consequences. The justification for reversing the improvements was provided by one of the three federal investigations conducted by the U.S. Bureau of Alcohol, Tobacco, Firearms and Explosives which alleged, without proof, that the West, Texas explosion was caused by arson and thus nonpreventable. This commentary reviews the details of this reversal and recommends that the U.S. Environmental Protection Agency, now under the Biden Administration, resurrect its 2016 Risk Management Program chemical disaster rule in order to prevent future chemical facility catastrophes.

COVID-19 pandemic lessons to facilitate future engagement in the global climate crisis.

The COVID-19 pandemic was declared a Public Health Emergency of International Concern (PHEIC) in January 2020. As of November 2020, over 54 million cases and over 1 million deaths have been reported globally. The sudden coronavirus global pandemic has also pointed to the importance of tackling the global climate crisis even more urgently. This article discusses six lessons drawn from the COVID-19 pandemic that can inform and facilitate greater future engagement in the global climate crisis. These lessons were identified through monitoring and analyzing media coverage of COVID-19 related events during the initial onset of COVID-19 in late January 2020 to June 30, 2020. The key lessons included the potentiality of reducing fossil fuel consumption and greenhouse emissions, the significance of responding late, a case for strong sustainability, the limits of rugged individualism, a (mis)trust in science, and the possibility of large-scale change. The insights put forward point to the fact that, like the COVID-19 pandemic, people need to continue to attach their health to expectations of government action in the context of the global climate crisis.

A survey of environmental and occupational work practices in the automotive refinishing industry of a developing country: Sonora, Mexico.

The automotive repair and refinishing industry has been studied intensively in industrialized countries, in part due to use of hazardous chemicals such as isocyanates and solvents, but little is known about industry practices in the developing world. The main objective of this paper was to investigate environmental and occupational work practices of this industry in a developing region, Sonora, Mexico. An integrated survey approach maximizes the opportunity for identifying risks as well as reducing risks. This investigation included detailed workplace visits to 41 body shops and 6 paint suppliers, as well as a survey of shop owners and 24 workers. Information was collected on work practices, level of technology in the shops, use of personal protective equipment, consumption and handling of hazardous chemicals and waste, hazard communication, and environmental consciousness. Most shops had little capital, outdated technology for exposure control, poor working conditions, high potential for exposure to hazardous chemicals, and little awareness of environmental and occupational health and safety. We concluded that work practices in the Sonoran auto refinishing industry are unsustainable and may pose a health risk to workers and the environment.

A review of employment conditions as social determinants of health part II: the workplace.

This is the second part of an article on employment conditions as social determinants of health and health inequalities. In part I of this article, we explored structural (external) employment conditions that affect health inequalities and health gradients. In this article, we try to examine the internal aspects of employment conditions that affect the same variables. It is not our intention to "box" employment conditions in a rigid framework within an internal domain of person-hazard interaction. The objective of examining this variable is to scrutinize internal aspects of employment conditions at a comprehensive policy level in conjunction with external contextual variables. Major occupational health concerns are examined in relationship to globalization, child labor, and work in the formal and informal sectors. Interventions that can eliminate or greatly reduce these exposures as well as those that have been unsuccessful are reviewed. Innovative interventions including work organization change, cleaner production, control banding, national and international coalitions, participatory training, and participatory approaches to improving the work environment are reviewed.

Occupational health among Latino workers: a needs assessment and recommended interventions.

Evidence suggests that Latino workers, along with other minority and low-income workers, face a higher risk for occupational disease than do other workers. Targeted surveillance and primary prevention interventions have been lacking or inadequate. The authors estimate the number of occupational disease deaths and new cases in Latino workers in the United States. Then, using data from New York City, they find that Latino workers are disproportionately employed in more hazardous occupations and underrepresented in less hazardous jobs. They suggest a comprehensive approach to address workplace disease in Latino workers, which involves primary prevention interventions, clinical services, educational approaches, research and surveillance, unionization and organization of workers, and legislation and regulation.

Prevention strategies in industrial hygiene: a critical literature review.

Little is known of the extent of use of industrial hygiene prevention and control strategies in actual workplaces. The recent occupational safety and health literature was identified as a potential source for identifying which strategies are being utilized and evaluated as a means of controlling or preventing chemical hazards. Using preestablished selection criteria, the peer-reviewed industrial hygiene literature 1994-1999 was searched for articles describing prevention and control strategies for chemical hazards in actual workplaces. Ninety-two articles were found and categorized by the type of strategy discussed, whether strategies were implemented and evaluated, and by several other categories. Almost three-quarters discussed engineering control strategies, mostly local exhaust ventilation. Administrative strategies, including housekeeping, personal hygiene, and medical surveillance, appeared in about half the articles. Personal protective equipment was considered in one-third of the articles, and primary prevention strategies, such as material substitution, were considered in one-quarter. Intervention effectiveness was not consistently evaluated in these articles. In response to these findings, recommendations are made to improve the evaluation and promotion of effective prevention and control strategies.

Joint occupational and environmental pollution prevention strategies: a model for primary prevention.

Occupational and environmental health issues are not always considered simultaneously when attempting to reduce or eliminate hazardous materials from our environment. Methods used to decrease exposure to hazardous chemicals in the workplace often lead to increased exposure in the environment and to the community outside the workplace. Conversely, efforts to control emissions of hazardous chemicals into the environment often lead to increased exposure to the workers inside the plant. There are government regulations in place that ensure a safe work environment or a safe outside environment; however, there is little integration of both approaches when considering the public's health as a whole. This article examines some of the reasons behind this dichotomy, focusing on the regulatory and policy frameworks with respect to workplace and environment that have resulted in the inability of the Occupational Safety and Health Administration (OSHA) and the Environmental Protection Agency (EPA) to coordinate their efforts to protect public health. The components of the Pollution Prevention Act and its potential to serve as a model for integrating occupational and environmental health are discussed. Limitations regarding enforcement of pollution prevention, as well as its disconnection from the work environment are equally highlighted. The article finishes by examining the barriers to integrating the occupational and environmental health paradigms and the promotion of primary prevention in public health.

Development models, sustainability and occupational and environmental health in the Americas: neoliberalism versus sustainable theories of development

This article describes the inherent contradiction between competitive capitalism and the pursuing of the "three bottom lines": 1) economic prosperity, 2) environmental quality (including the workplace) and 3) social justice. An alternative, genuine, sustainable approach to development; the Integrated Human Ecosystem Approach will be described and contrasted with neoliberal development. The IHE approach was developed by The International Development Research Center of Canada in 2001. In this approach, the triple bottom line is not a simple tool for neoliberal development, but the focus of allocation and management of resources for sustainable development. The acquisition of only state power by governments opposed to neoliberalism is necessary but not sufficient condition to successfully find a human alternative to the market ideology. A road map needs to be developed in which a clear definition of technologies that permit the acquisition and implementation of an alternative ideology to achieve "social power." The IHE model provides developing countries with the basis for that ideology

Analyses of the recycling potential of medical plastic wastes.

This study analyzed the recycling potential of plastic wastes generated by health care facilities. For this study, we obtained waste streams and recycling data from five typical city hospitals and medical centers and three animal hospitals in Massachusetts. We analyzed the sources, disposal costs and plastic content of medical wastes, and also determined the components, sources, types and amounts of medical plastic wastes. We then evaluated the recycling potential of plastic wastes produced by general city hospital departments, such as cafeterias, operating rooms, laboratories, emergency rooms, ambulance service and facilities, and animal hospitals. Facilities, laboratories, operating rooms, and cafeterias were identified as major sources of plastic wastes generated by hospitals. It was determined that the recycling potential of plastics generated in hospital cafeterias was much greater than that in other departments. This was mainly due to a very slight chance of contamination or infection and simplification of purchasing plastic components. Finally, we discuss methods to increase the recycling of medical plastic wastes. This study suggests that a classification at waste generating sources, depending upon infection chance and/or plastic component, could be a method for the improved recycling of plastic wastes in hospitals.

Primary prevention and precaution in hazard identification in the NIEHS/NTP: body in the morgue approach.

In the spirit of stimulating reevaluation of the methods of public health science, this article explores the methods of cancer hazard identification at the National Toxicology Program (NTP) from the perspective of primary prevention and precaution. The NTP is a cooperative effort of three federal agencies: The National Institute of Environmental Health Sciences (NIEHS, the lead government institute); the National Institute for Occupational Health (NIOSH), in the Centers for Disease Control and Prevention; and the National Center for Toxicology Research (NCTR), in the Food and Drug Administration. NTP coordinates toxicological research and testing programs within the Department of Health and Human Services (DHHS), and through its annual Report on Carcinogens (RoC), identifies and characterizes cancer hazards-the first step in quantitative risk assessment-for the federal government. The foundation of NIEHS policies, for environmental health research, is quantitative risk assessment (QRA). The author examines the opportunities for primary prevention and precaution, and the extent to which the policies of NIEHS in general, and the NTP in particular, do and do not realize that potential. Special attention is paid to the issue of cancer hazard identification. Critical comments on the process of classifying carcinogens in the Ninth and Tenth Reports on Carcinogens are presented, based on the minutes of the Board of Scientific Counselors Subcommittee meetings.
