Distillery Still Explosion
Inverness, Florida
Incident Summary
On April 17, 2026, an explosion occurred at Storm Distillery on North Apopka Avenue in downtown Inverness, Florida. The blast was audible over a mile from the source and caused a fire that spread through the building. The explosion caused physical damage to the distillery and the "Hometown Deli," which shares a common wall with the facility. Debris from the facility, including components of a distillation still, was found on the surrounding grounds.
The incident injured three individuals. David Mohr, the owner of the distillery, was airlifted to UF Health Shands Hospital in critical condition and died from his injuries on April 21, 2026. The two other injured individuals were also transported to medical facilities. The Citrus County Sheriff’s Office and Citrus County Fire Rescue shut down the downtown courthouse square for several hours following the event.
Industry and Facility Description
Storm Distillery is a small-batch, veteran-owned craft distillery that produces whiskey, vodka, rum, gin, brandy, and liqueurs. The facility combines industrial distillation operations with a public-facing cocktail lounge and "speakeasy" themed venue. In a typical craft distillery of this type, the production area usually contains high-proof ethanol (Class IB or IC flammable liquids) being heated in stills, while the front-of-house area serves as a tasting room for customers.
Speculation on Cause
The explosion likely involved the ignition of ethanol vapors that escaped the distillation equipment. Witness reports of debris from a still suggest that the primary vessel may have experienced a mechanical failure or an overpressure event. If the still was being operated at the time, a leak in a gasket or a failure in the condenser cooling system could have released flammable vapors into the room. If the ventilation system was not sufficient to keep the vapor concentration below 25% of the Lower Flammable Limit (LFL), an ignition source—such as an open flame from a boiler or an electrical spark—could have triggered the blast.
Application of Industry Standards
NFPA 30: Flammable and Combustible Liquids Code
NFPA 30 provides requirements for the safe storage and handling of flammable liquids. In this incident, several key sections could have addressed the hazard:
Ventilation: NFPA 30 requires mechanical ventilation for areas where flammable vapors may be released. This ensures that even in the event of a small leak, vapors do not accumulate to explosive levels.
Separation and Protection: NFPA 30 requires specific fire-rated separations between process areas and other occupancies. Proper fire walls might have reduced the damage to the shared wall of the Hometown Deli.
FM Global Data Sheet 7-74 (Distilleries)
FM Global’s DS 7-74 is a property loss prevention standard specifically for distilleries. It includes more stringent recommendations than standard building codes:
Spatial Separation: DS 7-74 recommends that distilling operations be separated from other buildings by at least 100 feet. If they must adjoin other buildings, they should be "completely cut off by blank fire walls."
Damage-Limiting Construction: The standard recommends the use of explosion-venting windows or roof panels. This "damage-limiting construction" allows the pressure of an internal explosion to be released safely through a pre-defined weak point, preventing the collapse of the primary structure or damage to adjacent businesses.
Drainage: It requires emergency drainage to prevent spills of burning alcohol from flowing into other areas of the building or neighboring properties.
