Polyurethane foam spraying machines may become the ultimate earthquake survival tool

If an earthquake strikes, human survival will rely on two abilities: building quickly and using local materials. 

The Polyurethane Foam Spray Machine, a seemingly ordinary industrial equipment, may become the ultimate survival tool in an earthquake.

Chapter 1 Why Polyurethane Foam?

Super Adaptability

Polyurethane foam expands 30 times in seconds, quickly filling gaps, insulating, waterproofing, and even resisting mild radioactive fallout.

Once cured, it is extremely hard (with adjustable density), comparable to concrete, but as light as plastic.

Energy Efficiency

Portable polyurethane spray machines require only a small generator or solar power, making them suitable for resource-scarce earthquake environments.

Versatile Materials

From building shelters to repair tools, from making rafts to blocking biohazards, one can of foam = 100 survival possibilities.

Safety warning
Fatal risk: Uncured foam releases toxic isocyanate gas, so you must wear a gas mask when operating!

Doomsday taboo: Do not spray continuously in a closed space - there have been survivors who died of suffocation due to the collapse of the basement caused by the expansion of foam.
