Washington — A new video emphasizes safe work practices for truck drivers transferring process fluids such as oil and gas from wells to other locations.

Developed by NIOSH, the video notes that from 2016 to 2020, at least 12 workers died while transferring fluids at well sites. The deaths resulted from cardiac events, combustion-related explosions, struck-by vehicle incidents, exposure to hydrogen sulfide and heatstroke.

During fluid transfers, flammable atmospheres present a hazard to workers, the agency warns. In addition, when fluid tanks are under pressure, hydrocarbon gases and vapors can escape, creating potentially toxic and oxygen-deficient surroundings that may cause damage to a worker’s eyes, lungs, central nervous system and heart.

In the 11-minute video, NIOSH encourages employers to select and implement effective controls from the Hierarchy of Controls. Engineering controls include safely venting or containing process fluid vapors by using a vapor recovery unit, as well as using conducting hoses and closed connections for fluid transfers. Administrative controls include worker training and workplace policies. Employers also should train workers on the proper use of personal, multiuse gas monitors and how to confirm the devices are functioning properly and placed within the worker’s breathing zone.

“Oil and process fluids can be transferred and transported safely and with minimal risks,” the video says. “But to do so, employers and workers must understand the hazards, know the risks, and be able to apply the appropriate controls under the appropriate circumstances to control the hazards and mitigate the risks involved. Doing so each time will save lives.”

Washington, D.C. March 6, 2023 – Today, the U.S. Chemical Safety and Hazard Investigation Board (CSB) issued a new Safety Alert titled “Hazards Posed by Discharges from Emergency Pressure-Relief Systems.” The CSB’s alert highlights hazards identified with emergency pressure-relief systems from four CSB investigations.  The alert advises facilities that while a discharge from emergency pressure-relief systems can help protect equipment from unexpected and undesired high-pressure events, it can also seriously harm or fatally injure workers and cause extensive damage to a facility if the discharge is not made to a safe location.

CSB Chairperson Steve Owens said, “All four of the incidents highlighted in the CSB’s safety alert underscore the importance of thoroughly evaluating emergency pressure-relief systems to ensure they discharge to a safe location where they will not harm people.”

The four incidents highlighted in the CSB’s safety alert resulted in 19 deaths and 207 injuries. They include:

  • On May 19, 2018, an ethylene release ignited, injuring 23 workers at the Kuraray America, Inc. ethylene and vinyl alcohol copolymer plant in Pasadena, Texas. The CSB’s animation of this event shows how this incident occurred during the startup of a chemical reactor system following a turnaround. High-pressure conditions developed inside the reactor and activated the reactor’s emergency pressure relief system, discharging flammable ethylene vapor horizontally into the ambient air in an area where a number of contractors were working.
  • On November 15, 2014, approximately 24,000 pounds of highly toxic methyl mercaptan were released from an insecticide production unit at the E.I. du Pont de Nemours and Company (DuPont) chemical manufacturing facility in La Porte, Texas. The release fatally injured three operators and a shift supervisor inside a manufacturing building. During the early phases of the investigation, CSB investigators identified a number of worker safety issues—separate from the release scenario— including that several emergency pressure-relief systems at the facility were designed to discharge hazardous materials in a way that posed a risk to workers and the public.
  • On May 4, 2009, highly flammable vapor released from a waste recycling process, ignited, and violently exploded at Veolia ES Technical Solutions, LLC, in West Carrollton, Ohio. The incident injured four employees, two seriously.  Following the initial explosion, multiple other explosions occurred that t significantly damaged every structure on the site. Residences and businesses in the surrounding community also sustained considerable damage. The CSB concluded that uncontrolled venting from emergency pressure-relief valves to the atmosphere allowed tetrahydrofuran (THF) vapors to accumulate to explosive concentrations outside process equipment, and the vapors subsequently found an ignition source.

Chemical Safety Board to chemical facilities: Remember cold-weather best practices

Washington — Alarmed by a recent surge of events involving the incidental release of chemicals during cold weather, the Chemical Safety Board is reminding facility operators of process safety management best practices for wintertime operations.

Freezing and expansion of water can crack or break pipes, damage equipment, or lead to instrumentation failure. Additionally, cold temperatures can trigger the formation of a hydrate, a chemical combination of water and a compound that may expand or block process piping.

CSB recommendations for winterization include:

  • Effectively identify and address the risk of freeze-related hazards to piping and process equipment through process hazard analyses, management of change evaluations, pre-startup safety reviews and operating procedures.
  • Create and implement a winterization checklist to ensure plant and process systems are ready for cold weather.
  • Establish a formal, written freeze protection program.
  • Survey piping systems for dead-legs (sections that have no flow) and ensure they’re properly isolated, removed or winterized.
  • Systematically review process units, including infrequently used piping and equipment, to identify and mitigate freezing hazards.

CSB data shows that 36 incidents related to the agency’s accidental release reporting rule were recorded during the first three months of fiscal year 2023, including eight during a Christmas holiday weekend that saw record-low temperatures across much of the nation.

The agency notes that 30 combined reportable events – incidental chemical releases resulting in a fatality, a serious injury and/or significant property damage – were observed during the first quarter of FY 2021 and FY 2022.

“Companies need to heighten their focus on safe operations and recognize that taking important precautionary actions, like winterization, can help prevent major chemical accidents,” CSB Chair Steve Owens said in a press release.

‘Take-home toxins’: Study shows construction workers may be putting family at risk

First published by Safety+Health an NSC publication

Boston — Construction workers are at increased risk of unintentionally tracking various toxic metals from the jobsite into their homes – potentially putting family members at risk, results of a recent study show.

Researchers from Boston University’s School of Public Health and Harvard University’s T.H. Chan School of Public Health visited the homes of 27 workers (21 in construction) who had at least one child to collect dust samples and make observations. They identified and measured for 30 different toxic metals. The workers completed a questionnaire regarding work- and home-related practices that could affect exposure.

Results showed that the construction workers’ homes had higher concentrations of arsenic, chromium, copper, manganese, lead, nickel and tin dust than the homes of the other workers, who had janitorial or automobile repair jobs.

The higher concentrations were associated with worker factors such as lower education, not having a work locker to store clothes, mixing work and personal items, not having a place to launder clothes, and not washing hands and changing clothes after work.

The researchers say the new data underscores the need for more proactive and preventive measures to reduce so-called “take-home toxins,” including policies, resources and education for workers and their families.

“Many professions are exposed to toxic metals at work, but construction workers have a more difficult job implementing safe practices when leaving the worksite because of the type of transient outdoor environments where they work, and the lack of training on these topics,” lead study author Diana Ceballos, an assistant professor of environmental health and director of the Exposure Biology Research Laboratory at BU, said in a press release. “It is inevitable that these toxic metals will migrate to the homes, families and communities of exposed workers.”

Ceballos adds that the issue is compounded when construction workers live in disadvantaged communities or substandard housing that may already contain toxic metals.

The study is scheduled to be published in the June issue of the journal Environmental Research.

EPA publishes second installment of risk evaluation for asbestos

First published by Safety+Health an NSC publication

Photo: ATSDR

Washington — The Environmental Protection Agency is seeking comment on a draft of Part 2 of a final risk evaluation that concludes asbestos – a known human carcinogen – presents an unreasonable health risk to workers under certain conditions.

Used in chlor-alkali production, consumer products, coatings and compounds, plastics, roofing products, and other applications, asbestos is among the first 10 chemicals under evaluation for potential health and environmental risks under the Frank R. Lautenberg Chemical Safety for the 21st Century Act.

Released Dec. 28 and announced via a notice published in the Dec. 29 Federal Register, Part 2 of the evaluation focuses on legacy uses and disposal of asbestos, defined by EPA as “conditions of use for which manufacture (including import), processing and distribution of commerce no longer occur, but where use and disposal are still known, intended or reasonably foreseen to occur (e.g., asbestos in older buildings).”

Part 2 addresses five other types of asbestos fiber beyond chrysotile – the focus of Part I, released early last year – as well as talc, which “has been implicated as a potential source of asbestos exposure,” the agency says.

After criticizing the first installment of the risk evaluation as “piecemeal and dangerously incomplete,” the nonprofit Asbestos Disease Awareness Organization, in a press release, applauds the agency for using a more informed and complete approach in proceeding with Part 2.

“[EPA] has taken a critical step in fulfilling its long-delayed obligation to evaluate the risks of legacy asbestos under the Toxic Substances Control Act,” ADAO President and co-founder Linda Reinstein said. “The Part 2 risk evaluation will finally provide a robust and comprehensive evaluation of legacy asbestos that can be found in millions of homes, schools and workplaces.”

Reinstein’s late husband, Alan, died from mesothelioma in 2006. She remains a proponent of an EPA ban on asbestos.

Comments on the draft of Part 2 of the risk evaluation are due Feb. 14. The agency is required to publish a final version on or before Dec. 1, 2024.

EPA final rule sets reporting requirements for 50 chemicals

First published by Safety+Health an NSC publication

Washington — The Environmental Protection Agency has issued a final rule that requires anyone who manufactures or imports 50 specified chemicals to report to the agency “certain lists and copies of unpublished health and safety studies” undertaken within the past decade.

This action is being taken, according to EPA, because the Interagency Testing Committee – established under the Toxic Substances Control Act of 1976 – has added the substances to its Priority Testing List. The chemical substances subject to the rule include 20 chemicals EPA has designated as high-priority substances for risk evaluation under the Frank R. Lautenberg Chemical Safety for the 21st Century Act, as well as 30 organohalogen flame retardants the Consumer Product Safety Commission is evaluating for risks under the Federal Hazardous Substances Act of 1960.

Under the rule, published in the June 29 Federal Register and slated to go into effect July 29, manufacturers and importers must submit:

  • Lists and copies of unpublished health and safety studies on health effects, such as toxicity studies on carcinogenicity, reproductive and developmental effects, genotoxicity, neurotoxicity, immunotoxicity, and endocrine effects
  • All unpublished studies on environmental effects, environmental fate and physical chemical properties if performed as described in 40 CFR 716.50
  • All unpublished studies on occupational (both users and nonusers), general population, consumer and environmental exposure
  • Studies showing any measurable content of the specified chemical in the tested substance, whether single substances or a mixture; the composition and purity of test substances must be reported if included as part of the study

Additionally, the rule is applicable to anyone who intends to manufacture or import the specified chemicals within 90 days of the EPA notice.

The 20 high-priority chemicals are separate from the first 10 chemicals being evaluated for potential health and environmental risks under the Lautenberg Act. The former group of chemicals includes:

  • Seven chlorinated solvents
  • Six phthalates, or hormone-disrupting substances, linked to several health issues
  • Four flame retardants
  • Formaldehyde
  • One fragrance additive
  • One polymer precursor

Requests to withdraw chemical substances from the final rule are due July 13. The requested information is due Sept. 27.

First published by Safety+Health an NSC publication.

West Lafayette, IN — Using newly developed algorithms, researchers from Purdue University have designed an image- and video-based application to detect combustible dust concentrations suspended in the air.

The application, which the researchers say can be used in agricultural, powder-handling or manufacturing settings, involves capturing images of a suspended dust cloud and then analyzing the light extinction coefficient. In testing, the algorithm was able to recognize 95% of sawdust and 93% of cornstarch particulates in the air, a university press release states, adding that the application was able to distinguish suspended dust from “normal background noise.”

Current technology for detecting dust levels can be expensive and difficult to install in workspaces, and separates dust matter into multiple filters that must be weighed and undergo additional analysis, according to the researchers. In contrast, the new application doesn’t require extended training, is location independent and doesn’t need to be permanently installed.

According to data from the Chemical Safety Board, between 2006 and 2017, 111 combustible dust incidents resulted in 66 worker deaths and 337 injuries in the United States.

“Determining suspended dust concentration allows employers to take appropriate safety measures before any location within the industry forms into an explosive atmosphere,” Kingsly Ambrose, an associate professor of agricultural and biological engineering, said in the release.

The research team, which has worked with the Purdue Research Foundation Office of Technology Commercialization to patent the technology, said the application can be used effectively in open and confined spaces.

The study was published online July 21 in the Journal of Loss Prevention in the Process Industries.

EPA publishes final risk evaluation for methylene chloride

Washington — Methylene chloride poses “unreasonable risk” to workers under certain conditions, according to a final risk evaluation recently released by the Environmental Protection Agency, which now is compelled to propose within one year regulatory action to mitigate the chemical’s hazards.

Frequently used for bathtub refinishing, methylene chloride is among the first 10 chemicals under evaluation for potential health and environmental risks under the Frank R. Lautenberg Chemical Safety for the 21st Century Act. In 2014, EPA found that exposure to the chemical may cause cancer, harm to the central nervous system and toxicity to the liver, among other adverse health effects.

The final evaluation, published June 19, is the first to be released for the 10 chemicals. Announced via a notice published in the June 24 Federal Register, the document states methylene chloride poses unreasonable risk to workers involved in numerous operations, including:

  • Plastic and rubber manufacturing
  • Electrical equipment, appliance and component manufacturing
  • Oil and gas drilling, extraction and support activities
  • Adhesive/caulk removal
  • Cold pipe insulation
  • Aerosol and non-aerosol degreasing and cleaning

Additionally, EPA determined an unreasonable risk is not present during the following conditions of use:

  • Domestic manufacture
  • Processing as a reactant
  • Recycling
  • Distribution in commerce
  • Industrial and commercial use as a laboratory chemical
  • Disposal

As required under the Toxic Substances Control Act, which the Lautenberg Act amended, EPA must address risks by proposing within one year regulatory actions such as training, certification, restricted access, and/or ban of commercial use, and then accept public comment on any proposals.

“Releasing the first final risk evaluation marks a key milestone in our efforts to fulfill our responsibilities for ensuring the safety of chemicals already on the market,” Alexandra Dapolito Dunn, assistant administrator of the EPA Office of Chemical Safety and Pollution, said in a June 19 press release. “By following the TSCA process, we can have confidence in our final conclusions and move forward with developing a plan to protect the public from any unreasonable risks.”

In March 2019, EPA published a final rule that prohibits manufacture (including import), processing and distribution of the substance in paint removers for consumer use, as well as requires manufacturers, processors and distributors to notify retailers and others in the supply chain about the ban.

EPA Administrator Andrew Wheeler said in the release that the action “builds on last year’s ban on consumer sales of certain methylene chloride products and will guide the agency’s efforts to further reduce risks from this chemical.”

Liz Hitchcock, director of the Washington-based advocacy group Safer Chemicals, Healthy Families, called on the agency to expedite its regulatory actions, contending in a June 19 statement that “the longer EPA drags its feet, the more lives will be lost.” According to Safer Chemicals, Healthy Families, at least 64 people have died from acute exposure to methylene chloride since 1980.

“The time for study and talk is long past,” Hitchcock’s statement reads. “EPA should take immediate action on the danger it has once again recognized in this risk evaluation and finish the job to protect workers. The agency must immediately finalize its proposed ban on commercial use of these products. To wait any longer to protect workers from these dangerous products when EPA has the ability to ban them now is unconscionable and will result in more preventable deaths.”

In April 2019, Safer Chemicals, Healthy Families was part of a coalition of groups representing worker rights that filed a lawsuit against EPA and Wheeler for excluding workers in the final rule.

EPA previously solicited comments on problem formation documents for the first 10 chemicals before releasing its first draft risk evaluation – for Pigment Violet 29 – in November 2018. The agency released its draft risk evaluation for methylene chloride in October.

EPA says it plans to release final risk evaluations for the remaining nine of the first 10 chemicals by the end of the year.
