New generation of fire blankets - effective protection against battery and liquid fires - developed in Switzerland
Fire extinguishers & old fire blankets - why they fail in modern fires and what the Heidi & Peter fire blanket do better.

Swiss households often still have fire blankets lying around that were purchased years ago. Well-intentioned - but often useless in an emergency. This is because most conventional fire blankets from older generations are not suitable for battery, liquid or metal fires. These outdated models can even be dangerous, especially with lithium-ion batteries such as those found in e-bikes, smartphones or tools.
Why conventional fire blankets are not sufficient for battery fires
Older fire blankets were primarily developed for grease fires or small incipient fires - but not for the high-energy, difficult-to-control fires of modern batteries.
- They char or melt when temperatures exceed 1,000 °C.
- They allow an uncontrolled supply of oxygen, which encourages re-ignition.
- They fail in the event of strong thermal shock, as is common with rechargeable batteries.
Conclusion: These products offer a deceptive level of safety - in an emergency, you are on your own.

🧯 Fire extinguisher? Not always the best choice
Many households rely on powder or foam extinguishers - often unsuitable for today's hazards:
- Powder extinguishers destroy entire rooms with fine dust
- Foam extinguishers fail with batteries - the fires flare up again
- CO₂ extinguishers are ineffective against intense heat and are not suitable for displacing oxygen inside
Heidi & Peter, on the other hand, isolate the source of the fire mechanically, prevent oxygen supply, without chemicals - and without consequential damage.
