Couple Dies from Carbon Monoxide Poisoning at New Forest Cider Festival
Leaky gas heater in enclosed van leads to tragic misadventure for stall traders at October event.

Christopher Coll, 45, and Kayleigh Coll, 38, were found dead in their Nissan van at the New Forest Cider Festival in October 2025, their deaths attributed to carbon monoxide poisoning.
Police confirmed the camper van's windows remained shut, sealing the couple's fate. This critical detail emerged during the investigation into the deaths of the stall traders.
Manufacturer safety guidelines explicitly warned against using gas heaters in enclosed spaces due to carbon monoxide risks. These crucial warnings remained tragically unheeded by the couple.
An examination of the gas heater and cylinder revealed improper fitting, directly causing a gas leak. This malfunction proved lethal, initiating the chain of events.
Expert Howard Jonas stated unequivocally that the heater was not properly attached to the cylinder. Even a small knock could dislodge the fitting and compromise safety, he confirmed.

Mara Sivyer, Ms. Coll's mother, highlighted a critical design mismatch. The van, used for the first time with heating the previous summer, was not originally designed as a campervan, creating an unforeseen hazard.
Ms. Sivyer described their decision to use heating in the unsuitable van as a 'fatal mistake.' Her words underscore profound grief and irreversible consequences.
Hampshire area coroner Rosamund Rhodes-Kemp recorded their deaths as misadventure. She emphasized that the heating activation had unintended, fatal consequences.
Rhodes-Kemp clarified that Mr. Huxley detected the smell of butane gas, but this proved largely inconsequential to their deaths. The odorless carbon monoxide poisoning ultimately proved fatal.
The gas cylinder was nearly depleted, with only 10% of its contents remaining. This indicated prolonged use before the tragic discovery.
This incident echoes historical warnings about improperly ventilated heating dangers. It recalls the 2013 Toledo, Ohio incident where carbon monoxide poisoning in a parked Ford Explorer with a flat tire led to three deaths and two hospitalizations.
The public health implications are significant, placing renewed pressure on festival organizers and equipment suppliers. They must now ensure stringent safety protocols and clearer warnings regarding portable heating devices.
To obtain permits for vendors in the Hampshire area, traders typically contact event organizers or the local municipality. Spaces in the Vendor Village for the Pups in the Pool event at the Muskingum County Family YMCA cost $5 each, highlighting the localized nature of event planning.
Stakeholders across the event industry, from local councils issuing permits to vendors selling camping equipment, now face increased scrutiny. Their roles in preventing such foreseeable accidents come under intense examination.
While no specific mention of mandated safety checks for heating equipment in vendor vehicles exists, the American Kennel Club's (AKC) new Unattended Dogs in Vehicles Policy emphasizes adequate ventilation and airflow. This policy aims to prevent risks associated with leaving dogs unattended in vehicles, underscoring a broader safety imperative.
Economically, the incident could lead to stricter regulations for mobile vendors and festival infrastructure. This may potentially increase operational costs for small businesses and event organizers.
The future landscape of outdoor events may see mandatory checks for heating installations in vendor vehicles. This moves beyond mere recommendations to enforceable safety standards.
This tragedy forces a re-evaluation of how information about safe appliance use is disseminated. It particularly impacts individuals operating in temporary or modified living spaces.
The Coll family's loss underscores the urgent need for widespread public awareness campaigns. These campaigns must ensure the lessons learned from this misadventure prevent future fatalities.

The incident highlights the critical importance of carbon monoxide detectors in any enclosed space where fuel-burning appliances are used. A simple measure could have averted this devastating outcome.
