OSB (Oriented Strand Board) is a wood-based panel product, not a liquid. Therefore, it does not have a flashpoint in the traditional sense. However, OSB can still be flammable and can ignite if exposed to a heat source.
It's important to note that:
* OSB is often treated with fire retardants. This can increase the temperature at which it will ignite.
* The specific flammability of OSB can vary depending on the manufacturing process and the type of wood used.
* OSB is generally considered less flammable than plywood.
While OSB doesn't have a specific flashpoint, it's essential to be aware of its flammability and take appropriate precautions to prevent fires.
