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.

Micromobility in Smart Cities: Keeping the Wheels in Motion

May 26, 2026 — James P. Bobotek - Gravel2Gavel Construction & Real Estate Law Blog
Mobility is the lifeblood of any city. How people are able to travel in, out and within a metropolitan area is vital to its citizens, businesses, supply chains and social services. And as U.S. cities have expanded in size and population density, the strategies for addressing mobility have evolved. Many have taken different approaches to public transit, and each city boasts a dense tapestry of roadways, walking paths and various parking options. But as cities continue to reexamine infrastructure strategies through smart city technology, a new field of transportation has emerged—micromobility. Designed for short-distance travel using lightweight vehicles (bikes, e-bikes, e-scooters, etc.), the industry’s global net worth has grown exponentially in recent years to the tune of hundreds of billions, with one forecast predicting it could reach $340 billion by 2030. Micromobility also finds itself at the forefront of various smart city technological improvements. Geofencing has been implemented in U.S. cities to determine where micromobility vehicles can operate, control speed limits, and park utilizing the vehicles’ GPS location. Internet of Things (IoT) technologies (satellite-based location receivers, cloud communication, internet links, etc.) have improved vehicle lifespans by keeping track of when vehicles require service and prevent vandalism and theft. Data collected from vehicles’ location tracking is routinely used for urban planning and smart city development. Read the full story...

Predict Risk, Not Incidents: A New Analytics Framework for Your Construction Safety Data

August 03, 2026 — Tabrez Zahoor - Construction Executive
Behind every “zero-incidents” company report, hidden hazards may already be accumulating—risks that could become serious injuries tomorrow. The question every executive should be asking is not, “Did anything go wrong last month?” It is: “Where is risk building on my projects right now?” Most construction organizations cannot answer that question. Not because the data does not exist—it does. Every active project generates daily inspection findings, labor records, near-miss reports and audit results. The problem is that standard safety systems collect this data and then report it in ways that make it operationally useless for prevention. They describe the past. They predict nothing. The predictive safety analytics framework (PSAF) is a practical, deployable system developed from years of applying data science to large-scale construction portfolio operations that takes the safety data construction organizations already collect and transforms it into a forward-looking risk signal. The result? A single weekly score that tells executives where risk is concentrating across their portfolio before anyone gets hurt.

That’s a Wrap! Pennsylvania Court Holds Arbitration Clause in Online Agreement Unenforceable

May 14, 2026 — Gus Sara - The Subrogation Strategist
In Duffy v. Tatum, 2026 Pa. Super. LEXIS 112, 2026 PA Super 41, the Superior Court of Pennsylvania (Superior Court) considered whether an arbitration provision contained in the online Terms of Service on the defendant’s website were enforceable. The plaintiff, Daniel Duffy (Duffy), visited the website of defendant, Dolly, Inc. (Dolly), to purchase moving services. Duffy selected the number of movers, items to be moved and the type of vehicle needed. To complete the booking, the website required Duffy to checkmark a box labeled “By checking this box I accept the Dolly Terms of Service.” Duffy did not have to open the link or scroll to the bottom of the agreement before being able to click on the checkmark box. The Terms of Service included an arbitration provision requiring that any dispute related to the moving services to be resolved by arbitration in accordance with the American Arbitration Association. The Terms of Service did not include any statement that the user was waiving the right to a jury trial. The Superior Court found the internet Terms of Service unenforceable. During the moving process, an accident occurred and injured Duffy. In May 2024, Duffy and his wife sued Dolly and other related entities alleging negligence and loss of consortium. Dolly filed preliminary objections alleging that the parties agreed to alternative dispute resolution. The lower court overruled the preliminary objections, finding that Dolly’s website did not provide reasonably obvious notice of its Terms of Service to Duffy and, as such, Duffy never agreed to waive his constructional right to a jury trial. Dolly filed an appeal to the Superior Court. Read the full story...

Vacant Building Negates Coverage for Broken Pipe

September 01, 2026 — Tred R. Eyerly - Insurance Law Hawaii
The Michigan Court of Appeals found the insured was not covered for water damage because the commercial space was left vacant. Cherry Hill Recreation Center, Inc. v. Conifer Ins Co., 2026 Mich, App. LEXIS 5099 (Mich Ct. App. June 18, 2026). Alan Abbas purchased a bowling alley. Due to the onset of the COVID-19 pandemic and executive orders issued by the governor, Abbas was unable to operate the bowling center for several months. During the winter, Abbas allowed the thermostat to drop significantly, with the building expected to be around 43 degrees Fahrenheit. He later admitted the sprinkler system’s pipes were not protected against freezing. Read the full story...
