Bismarck, N.D. — The North Dakota State Fire Marshal’s Office is calling on long-term care providers, families, and caregivers to double down on oxygen safety after a devastating fire at a Massachusetts assisted living facility killed 10 residents earlier this month.
Investigators say several of the residents relied on home oxygen therapy, which can act as an accelerant and cause a fire to spread quickly.
“This tragedy is heartbreaking, and it hits close to home for anyone who works with our vulnerable populations,” said Doug Nelson, North Dakota State Fire Marshal. “Oxygen doesn’t burn on its own, but it feeds fire. A tiny spark—a cigarette, a candle, even an electrical short—can turn into a deadly blaze in seconds when oxygen is in use.”
North Dakota has more than 70 licensed nursing homes and over 80 assisted living facilities, many with residents who use oxygen. While these facilities follow strict fire safety codes, the State Fire Marshal’s Office reminds staff and families to review and reinforce oxygen safety practices.
Thermal Fuse CutOffs (TFOs): A Critical Layer of Protection
TFOs are small safety devices that shut off oxygen flow if tubing ignites.
Ask your oxygen supplier about TFOs.
Train staff and caregivers on how to recognize and maintain this feature.
“Thermal fuse cutoffs are an added layer of safety,” Nelson said. “They don’t replace commonsense precautions, but they can make a lifesaving difference if something goes wrong.”
Key safety steps when oxygen is in use:
No smoking, ever. Sparks from cigarettes, cigars, or pipes can ignite clothing, bedding, or furniture instantly.
Keep oxygen at least 5–10 feet from flames or heat sources.
Use only approved equipment. Do not modify tubing, connectors, or flow meters.
Store oxygen cylinders securely, upright, and away from heat sources and clutter.
Post “Oxygen in Use – No Smoking” signs. Alert visitors and caregivers immediately upon entering the home or room.
Confirm TFOs are installed and understood.
“North Dakotans have a proud tradition of caring for each other, and many families care for loved ones on oxygen therapy,” Nelson said. “Please take a few minutes to review safety steps with staff, residents, and family members. That simple conversation can save lives.”
