The GKN Aerospace Chemical Release and the Laws Designed to Address It

July 06, 2026 — Sean M. Sherlock - Snell & Wilmer
On May 21, 2026, a 34,000-gallon storage tank at the GKN Aerospace facility in Garden Grove, California began leaking methyl methacrylate (MMA), a volatile and highly flammable industrial chemical used to manufacture high-strength acrylic plastics. GKN Aerospace makes advanced military and commercial transparencies, such as aircraft canopies, windshields, cabin windows, bullet-resistant glass, and spacecraft windows. In polymer chemistry lingo, MMA is known as a monomer. Monomers are like individual links to a chain. Under the right conditions they link up (react) with each other to form long-chained polymers, or plastics. MMA is an unstable monomer that requires controlled storage conditions to avoid setting off a polymerization (chain) reaction. According to early reports, the MMA tank at GKN Aerospace overheated. The cause of the overheating is not yet clear, but the overheating may have created conditions enabling the MMA to initiate polymerization, which in turn generated heat, which in turn generated pressure, activating the tank’s pressure-relief system and releasing MMA vapor into the atmosphere. Concerns about a runaway reaction, massive release, and explosion led the Orange County Fire Authority to order evacuation of approximately 40,000 residents and closure of thirteen schools.

The Seventh Circuit Rejects Navigators Insurance Company’s Attempt to Escape Additional Insured Coverage For a Gas Explosion

March 24, 2026 — Kyle A. Rudolph & Anna M. Perry - Saxe Doernberger & Vita, P.C.
In a recent Seventh Circuit decision, Atlanta Gas Light Company v. Navigators Insurance Company, the court addressed a theme that policyholders are often confronted with by insurers[1] – insurers disputing additional insured coverage where the named insured is not named in the underlying action. The court aptly rejected this position since it was undisputed that the bodily injuries alleged in the underlying lawsuits were due to a gas explosion that was “caused, in whole or in part, by” the named insured’s acts or omissions. I. Background The additional insureds, Atlanta Gas Light Company and Southern Company Gas (collectively, “AGL”), retained the named insured, United States Infrastructure Corporation (“USIC”), to locate and mark gas lines that AGL owned in Georgia. USIC failed to mark a certain gas line, which was later struck by a boring company, leading to an explosion that injured three people. Reprinted courtesy of Kyle A.

Labor Shortages in Construction: Managing Legal and Operational Risks

April 14, 2026 — Meghan Douris - Construction Executive
Labor shortages in the construction industry have become more than a scheduling headache—they are a legal and financial risk multiplier. As contractors scramble to meet deadlines with limited manpower, shortcuts in compliance, safety and subcontractor oversight become more likely. These gaps can expose companies to regulatory penalties, contractual disputes and reputational damage. Understanding how workforce constraints intersect with labor laws and contractual obligations is critical to mitigating the risks and navigating these challenges without compromising compliance or project integrity. The construction industry has faced persistent workforce challenges for years, but recent trends have intensified the problem. Factors such as an aging workforce, reduced immigration and post-pandemic recovery pressures have left contractors struggling to find skilled labor. According to Associated Builders and Contractors, the construction workforce shortage surpassed half a million workers in 2024; in the same year, Associated General Contractors reported 88% of construction companies had difficulty finding qualified workers.

“The Superintendent Told Us to Do It:” Why Verbal Approval May Not Be Enough

June 02, 2026 — Andrew Lintner - Colorado Construction Litigation Blog
In construction defect litigation, one scenario appears repeatedly: a subcontractor installs work in a manner that differs from the plans, specifications, manufacturer instructions, or industry standards after being verbally directed to do so by the general contractor, superintendent, architect, or owner’s representative. At the time, the decision may seem minor. The project is moving quickly, the field team wants to maintain progress, and nobody wants to stop working over what appears to be a small issue. The subcontractor may trust the superintendent or project manager and assume the conversation will be remembered later if questions arise. Years later, however, when the project experiences problems, the people involved may deny the conversation occurred, remember it differently, or simply no longer remember the project. Without written documentation, the subcontractor can find itself defending claims for defective work, even though it performed the installation exactly as directed. Read the full story...
