The Sherman Laboratory at the University of Hawaii at Manoa campus caught fire this afternoon after an experiment went awry.

The Honolulu Fire Department reported that it received a call at 2:30 p.m. about a building fire at the building on East West Road. The department said a ‰??student placed an experiment into some type of oven, which caused it to catch fire.‰?? UH security, which called HFD, was notified of the fire.

HFD arrived on the scene at 2:47 p.m. and saw ‰??heavy smoke‰?? coming from the second story of the four-story building, although everyone had evacuated from the building. Just a few minutes later, firefighters extinguished the fire.

Ottawa Fire Services hazardous materials specialists were called to Ottawa International Airport Thursday morning when officials reported a fire in a box.

There was a strong odour coming from the fire, with a popping noise, and officials were taking no chances.

The specialists determined the fire was in a lithium battery that had malfunctioned in a small electrostatic sprayer.

The device was placed in a drum with a special suppressant called ‰??Cold Fire‰?? to halt the chemical reaction was halted.

The area was then ventilated. There were no injuries.

Tags: us_WI, industrial, follow-up, environmental

ROCKTON‰??A number of fire departments that responded to the Chemtool chemical fire on June 14 in the Town of Rockton plan to seek reimbursement from the company for equipment that was damaged in the emergency response, according to multiple Stateline Area fire chiefs.

Rockton Fire Protection District Chief Kirk Wilson, who served as the incident commander on scene, said Rockton Fire lost about $12,000 in fire hoses, along with 15 sets of turnout gear, what firefighters wear during a response, had to be professionally cleaned and inspected.

Wilson added ladder truck had to be inspected for damage due to heat from the massive blaze, with reimbursement requests to be sent to Chemtool.


‰??We won‰??t have a clear picture of a total cost until all invoices are received,‰?? Wilson said.

South Beloit Fire Chief Dan Zerfass said fire crews abandoned multiple fire hoses, nozzles and turnout gear at the Chemtool fire scene. The cost of the department‰??s loss totals around $5,000.

The equipment was abandoned after Wilson made the call to evacuate the area due to the dangerous nature of the fire scene. The incident command location was moved after it was determined it was too close to the fire, officials said.

The Industry Ministry has told Ming Dih Chemical to relocate its operation to an industrial estate if it wants to continue operating in the kingdom following the fire on Monday that affected at least 80,000 residents in Samut Prakan.

Industry Minister Suriya Jungrungreangkit said the Department of Industrial Works has ordered the company to close down its factory, located among communities in King Kaew 21 at Moo 15 village in tambon Rachathewa, in Bang Phli district of Samut Prakan.

This follows an explosion on Monday that killed one rescue worker and injured 39 others.

The blast also caused the evacuation of people living in the area. There were concerns that chemical fumes might affect the residents.

PARTIES AGREE ON $1 MILLION SETTLEMENT IN SUPERIOR REFINERY EXPLOSION CLASS-ACTION LAWSUIT
https://www.duluthnewstribune.com/business/energy-and-mining/7106034-Parties-agree-on-1-million-settlement-in-Superior-refinery-explosion-class-action-lawsuit
Tags: us_WI, industrial, follow-up, environmental, hydrofluoric_acid

A proposed class-action settlement could make evacuees of the April 26, 2018, Husky Energy refinery explosion eligible to receive $150 in compensation.

According to the settlement agreement dated June 24, the plaintiffs, Jasen Bruzek, Hope Koplin and Christopher Peterson, and defendant Superior Refining Co. agreed to a settlement totaling $1.05 million, which is pending approval by a judge in the U.S. District Court for the Western District of Wisconsin.

Much of Superior was forced to evacuate for 18 hours when an explosion, likely caused by a faulty valve, caused a fire at the refinery. The evacuations were based on the fear of a hydrogen fluoride release, though none escaped the tank.

The settlement stems from a lawsuit the plaintiffs filed in 2018, claiming that while Husky allowed evacuees to file claims for evacuation expenses ‰?? transportation, lodging and lost wages ‰?? as well as separate claims for bodily harm, the reimbursements were ‰??skewed‰?? to people who could afford the up-front costs of a hotel room.

Court documents estimate nearly 21,000 people over 18 are eligible to file a claim, but the settlement funds would only be able to fulfill 5,833 claims at $150 per person. A household would be eligible for up to $300. Under certain circumstances, individuals may receive up to $200 and households up to $400.

CALL FOR POSTGRADUATE RESEARCHERS TO BE TREATED LIKE STAFF, NOT STUDENTS
https://www.chemistryworld.com/news/call-for-postgraduate-researchers-to-be-treated-like-staff-not-students/4013965.article
Tags: United_Kingdom, education, discovery, environmental

Universities treating postgraduate researchers (PGRs) as students rather than staff is unfair and must change, according to the University and College Union (UCU). The UCU wants universities to sign up to a manifesto it has drafted which calls for PGRs to be given basic employee rights and benefits.

The manifesto also demands that PGRs should have access to adequate facilities to complete their research together with regular feedback and support. It states that PGRs should not be required to deliver unpaid teaching duties as part of a scholarship, bursary or stipend. PGRs who teach, often known as graduate teaching assistants (GTAs), should have agreed hours and rates of pay, a job description and access to a pension scheme. Additionally, the manifesto calls for funded work extensions for PGRs impacted by the pandemic.

‰??PGRs produce high-level research and also deliver excellent teaching, but for some reason universities don‰??t consider any of this to be work and treat them as students instead, exploiting them all the way,‰?? says UCU general secretary Jo Grady. ‰??As a result, they miss out on some of the most basic benefits, such as access to sick leave and parental leave. This is totally unacceptable, as is the practice of making some PGRs even pay for the privilege of doing research at a university [as some PhDs are unfunded].‰??

US GROUPS BACK PRINCIPLES FOR CHEMICAL INGREDIENT DISCLOSURE
https://cen.acs.org/safety/consumer-safety/US-groups-back-principles-chemical/99/i25
Tags: public, discovery, environmental

US businesses, state regulators, and health advocacy groups are endorsing principles for disclosing chemical ingredients in products.
With the exception of substantiated trade secrets, the principles call for companies to disclose all ingredients they intentionally add to their products. They also ask manufacturers to disclose any incidental components, breakdown products, or by-products that pose known or suspected hazards to human health or the environment. Such disclosures would include carcinogens, mutagens, endocrine disruptors, allergens, and substances that can cause reproductive or developmental problems.
In addition, the principles seek more toxicity data so the hazards of chemicals used in products can be better understood.
‰??The requirement for chemical ingredient disclosure will increase as demand grows for a circular economy that aims to reuse and recycle products,‰?? says Mark Rossi of Clean Production Action, a group that promotes development and use of green chemicals, sustainable materials, and other environmentally preferable products. Hazardous chemicals have ended up in some plastic cutlery and children‰??s toys made from recycled plastic because the recyclers didn‰??t know the substances were in the material, Rossi says in a statement.

BIG CHANGES AFOOT FOR US CHEMICAL RISK EVALUATIONS
https://cen.acs.org/policy/chemical-regulation/Big-changes-afoot-US-chemical/99/i25
Tags: public, discovery, environmental, solvent, waste

Facing lawsuits and criticism from scientists, environmental groups, and the chemical industry, the US Environmental Protection Agency is overhauling its approach for evaluating risks associated with high-priority chemicals that are already on the market. According to Michal Freedhoff, head of the EPA‰??s chemicals office, the changes will impact the first 10 assessments completed by the Trump administration under the amended Toxic Substances Control Act (TSCA). They will also affect the next 24 assessments, which the EPA has already begun, and those that the agency conducts in the future.
The changes include assessing exposure to chemicals from air and water, as well as from land disposal. During the Trump administration, the EPA disregarded such pathways, claiming that they were already regulated by other statutes, such as the Clean Air Act and Clean Water Act. For 6 of the first 10 chemicals, the EPA will develop a screening approach that uses existing ambient air and surface-water data to evaluate risks to fenceline communities that border industrial facilities.
The EPA also plans to reopen its assessment of the solvent 1,4-dioxane, a widespread drinking-water contaminant, to determine whether drinking water and air exposure pose unreasonable risks to the general population. The agency will also evaluate occupational exposures to 1,4-dioxane generated as a manufacturing by-product that were not considered in its previous assessments.

Tags: us_CA, public, explosion, injury, ethanol

One person was transported to UMC Trauma following what was described as an explosion at a local hemp production facility on Friday, July 2.
Pahrump Valley Fire and Rescue Services Chief Scott Lewis said crews were dispatched to the NectarTek facility located along the 2400 block of Larsen Drive just after 6 a.m.
‰??We were dispatched for a report of a burn victim,‰?? he said. ‰??Initially, it was a single resource response but then we were informed there was a possible explosion and the involvement of chemicals. Eventually there was a report that there was possibly ethanol in the facility that caused the explosion.‰??

Lewis also said the response was upgraded accordingly by adding additional engine companies, along with a medic unit upon arrival.
‰??The engine one crew found that there was nothing showing from the exterior, but they did have a burn victim,‰?? he noted. ‰??The burns were significant enough to warrant flight to the UMC Burn Center, where we added Mercy Air- 21 to the assignment. Patient care was transferred and that patient was subsequently flown out.‰??
Lewis went on to say that the initial investigation revealed there was a flash-fire type incident within the structure, which prompted the response of the deputy state fire marshal, along with other personnel.

Tags: us_WA, industrial, discovery, environmental, radiation

More than half of all current and former workers involved in the Hanford Nuclear Reservation cleanup effort have said they were exposed to hazardous materials, according to a new report from the Washington state government.

The report, the last in a series from the Department of Commerce‰??s Hanford Healthy Energy Workers Board, found that 57 percent ‰??of all current and former workers reported being in an exposure event,‰?? with 32 percent saying they experienced ‰??long-term exposure to hazardous materials.‰??

The 106-page document cited ‰??deep concerns‰?? among current and former workers about ‰??compensation system processes and the healthcare system's ability to meet workers' needs,‰?? and identified ‰??deficiencies in continued engagement with workers after an initial assessment or diagnosis as a common obstacle for the Hanford workforce.‰??


The findings cap eight months of research by a state-commissioned board tasked with making recommendations on addressing the health needs of workers at the Hanford nuclear site.

Crews from Bucks County and New Jersey spent much of Wednesday afternoon and evening at a Falls Township facility for a hazmat call.

Firefighters were first dispatched to the Covanta facility on Middle Drive inside the Keystone Trade Center, formerly the U.S. Steel property, around 1:30 p.m. for a report of fumes inside a building.

Fire Marshal Rich Dippolito said the call was upgraded to add several fire companies and the Bucks County and Trenton hazmat teams.

Workers inside the facility operated by Covanta, a metal recycling company, sprayed a dust cloud of aluminum dross, a byproduct of aluminum smelter plants, with water. The mix of water and dross caused a chemical reaction that filled the facility with potentially dangerous fumes, Dippolito said.

No injuries were reported, but higher-than-normal levels of fumes remained in parts of the facility into Wednesday evening, the fire marshal said.

UPDATE (WKOW) -- One person was taken to the hospital following a possible hazardous material leak in Portage, according to the Portage Fire Department.

In a news release early Thursday morning, authorities said they were called to the area of Averbeck and Volk Street just before 7 p.m. Wednesday for a report of a Canadian Pacific (CP) Rail employee who may have inhaled toxic fumes.

The man was working around railcars when he began to experience some medical issues.

While Aspirus MedEvac treated the employee, the Portage Fire and Police Departments worked with CP Rail personnel to figure out the best course of action.

Columbia County Emergency Management, along with police, contacted residents and asked them to shelter in place.

Crews got to work to investigate.

"After monitoring the atmosphere in the area of the possible railcar leak, the crew wasn‰??t able to detect any readings of a hazardous chemical," said the press release.

WYOMING, Mich. (WOOD) ‰?? An anhydrous ammonia leak in Wyoming drew hazmat crews to a company and prompted warnings for neighbors before being contained Tuesday morning.

The leak was discovered around 10 a.m. in the 500 block of 32nd Street SE at Roger B. Chaffee Memorial Boulevard, the Wyoming Department of Public Safety said in a release.

Employees at State Heat Treating Company, which performs chemical treatments on metals for the automotive, furniture, medical and military industries, said they noticed the leak and quickly called 911.

About 300 to 500 gallons of vaporized ammonia escaped from one of the company‰??s tanks, Wyoming DPS Lt. Eric Wiler said. Hazmat crews responded to deal with the colorless, compressed, corrosive gas and managed to close the tank valve.

A lighting strike is being eyed as the cause of a small fire that broke out Friday evening at the Shintech polyvinyl chloride (PVC) manufacturing complex in Plaquemine, LA, several local news organizations reported.

‰??A lightning strike caused a transformer fire at Shintech‰??s facility in Plaquemine. Onesite emergency teams are responding to the fire, which is isolated to one area of the facility,‰?? Danny Cedotal, vice president of manufacturing for Shintech told television news station WAFB.

The company said it is shutting down production units at the Louisiana site to gauge how weather will impact the facility. Tropical Storm Elsa has led to rainstorms and high winds along the Gulf Coast.

No injuries were documented during the incident, according to The Baton Rouge Advocate.

CHEMICAL UPCYCLING

Economics is central to invigorating the transition to a circular economy for plastic

Gary Anderson designed the recycling mobius loop logo in response to a competition held in 1970 by the Container Corporation of America. Contestants were asked to design a simple symbol for recycled paper. These days that symbol is everywhere. And these days, our domestic recycling bin is nearly always full ‰?? yet I find it hard to believe that it was only in July 2009 that my hometown expanded its kerbside recycling collection service to include cans and plastic bottles. Putting plastic in your recycling bin, however, does not guarantee that it gets recycled effectively.

Sorting mixed streams of plastic waste efficiently and accurately is an onerous but essential step for most recycling methods. The technology employed to sort this mish-mash of household refuse has now become surprisingly sophisticated. Hayley Bennett‰??s recent feature on ferrofluids revealed how a company in the Netherlands is using magnetic nanoparticles suspended in ferrofluids as part of a density-based sorting process. Sorting matters, because the higher the homogeneity of the waste stream the higher the chance of the polymers retaining their value when they are recycled.

INVENTORY FINDS MORE THAN 10,000 CHEMICALS USED IN PLASTICS MANUFACTURE
https://cen.acs.org/environment/Inventory-finds-10000-chemicals-used/99/i25
Tags: Europe, laboratory, discovery, environmental, plastics

More than 10,000 additives, processing aids, and monomers are used to make plastics, with about 2,400 identified as potentially hazardous, according to the results of a comprehensive study cataloging publicly known chemicals used in plastics manufacture (Environ. Sci. Technol. 2021 DOI: 10.1021/acs.est.1c00976). The findings point to a long, tough road to close gaps in chemical regulations and improve plastic waste management, the study authors say.
Plastics are perhaps the most diverse class of synthetic materials, coming in every color, level of transparency, and stiffness. This range of properties is thanks to the sheer number of ingredients, such as pigments, fillers, or plasticizers, that can be combined with polymers.
While researching plastics recycling as part of her graduate studies, Helene Wiesinger of the Swiss Federal Institute of Technology (ETH), Zurich, realized that the large number of substances that go into plastics‰??and the little that is known about them‰??poses a big problem for plastic waste management. For instance, hazardous additives appropriate for one type of product, such as flame retardants in electronic casings, may wind up inside recycled material and eventually in products where they become inappropriate, such as toys. A report on the problems with plastics recycling and incineration published last week by International Pellet Watch, a program monitoring marine plastic pollution, and the International Pollutants Elimination Network, a global coalition of health and environmental advocacy groups, shared some of Wiesinger‰??s concerns.

DELTA-8-THC CRAZE CONCERNS CHEMISTS
https://cen.acs.org/biological-chemistry/natural-products/Delta-8-THC-craze-concerns-chemists/99/i31
Tags: public, discovery, environmental, other_chemical

Move over cannabidiol (CBD). The popularity of another cannabinoid, ‰??8-tetrahydrocannabinol (delta-8-THC), is on the rise. Found in gummies, vape cartridges, tinctures, and other products, delta-8-THC is popping up in gas stations, convenience stores, tobacco shops, and cannabis dispensaries throughout the US and beyond‰??often with no age restrictions.

Unlike CBD, delta-8-THC produces euphoric effects that are similar to but milder than those of delta-9-THC, the well-known psychoactive compound in cannabis. Delta-8-THC is an isomer of delta-9-THC. The only difference between the two molecules is the location of a double bond between two carbons.
