Industrial Fire and Propane Explosions at Plastics Facility
South Haven, Michigan
Incident Summary
On the afternoon of Friday, September 25, 2026, a five-alarm industrial fire broke out at the East Jordan Plastics facility located in South Haven, Michigan. According to South Haven Area Emergency Services (SHAES), the fire appears to have originated near an outdoor propane filling station. The fire subsequently engulfed stored propane tanks, resulting in a series of BLEVEs (Boiling Liquid Expanding Vapor Explosions) and pressure vessel ruptures that launched cylinders hundreds of feet into the air.
Due to the facility's proximity (approximately 200 yards) to the city's main electrical substation, municipal utilities temporarily disconnected electric service to the entire city to mitigate compounding hazards. Emergency responders from 13 departments across three counties operated for approximately 14 hours, utilizing an estimated two million gallons of water to contain the fire by 7:00 PM and clear the scene by Saturday morning. All personnel safely evacuated the facility, and no injuries were reported. The Michigan Department of Environment, Great Lakes, and Energy (EGLE) and the U.S. EPA subsequently took oversight of environmental monitoring and runoff mitigation.
Facility and Industry Overview
East Jordan Plastics is an industrial manufacturer specializing in thermoformed horticultural packaging, including plastic flats, plug trays, pots, and containers manufactured largely from recycled polystyrene and other polymers. The South Haven site functions as an extrusion, thermoforming, and distribution hub, handling high thermal-load inventories of finished thermoplastics alongside industrial support systems such as propane-fueled material-handling fleets and bulk fuel dispensing setups.
Speculation on Potential Contributing Factors
The initial fire may have resulted from a mechanical failure, hose rupture, or static discharge during liquid propane transfer operations at the filling station.
The rapid escalation to catastrophic tank ruptures indicates a lack of sufficient spatial separation or passive fire-resistive barriers between the dispensing station and bulk propane cylinder storage arrays.
Radiant heat exposure or direct flame impingement on uninsulated, non-depressured vessels likely caused rapid shell overheating above the liquid level, weakening vessel metallurgy and inducing thermal BLEVE events.
Proximity to outdoor polymer storage or shipping pallets may have provided secondary combustible fuel loads, accelerating radiant heat feedback to adjoining infrastructure.
Applicable Consensus Standard: NFPA 58 (Liquefied Petroleum Gas Code)
NFPA 58 establishes mandatory requirements for the storage, handling, transportation, and utilization of LP-Gas. Application of this standard directly addresses the physical hazards observed:
Separation Distances and Siting (NFPA 58, Chapter 6): Establishes minimum separation distances between propane storage containers, dispensing points, and adjoining important buildings, property lines, or heavy industrial storage, designed to minimize fire propagation risks.
Emergency Shutoff and Excess-Flow Protection (NFPA 58, Section 5.12 and 6.13): Specifies requirements for emergency shutoff valves (ESVs), thermal-actuated links, and excess-flow check valves on liquid dispensing lines to halt unconfined releases if a transfer hose severs or ignites.
Impact and Physical Exposure Protection (NFPA 58, Section 6.8): Requires robust physical protection (such as crash bollards and noncombustible canopies) and restricts the accumulation of combustible materials (such as wood pallets or plastic stock) within 10 feet of LP-Gas containers.
Container Pressure Relief and Thermal Protection (NFPA 58, Section 5.9): Mandates properly sized spring-loaded pressure relief valves and evaluates passive thermal insulation, mounding, or dedicated fixed water-spray systems (referencing NFPA 15) to mitigate vessel skin overheating during direct flame contact.
