Silent but deadly

Whist waiting further news on the building insulation front I perused the technical documentation concerning the product. Apparently small amounts of hydrogen sulfide* are trapped inside the bubbles of glass that go to make up the insulating foam. The H2S is a byproduct of the manufacturing process. On cutting or applying pressure to the foam slabs small amounts of H2S are released. The manufacturer advises strongly that the cutting takes place outdoors and not in a non ventilated enclosed space.

I wonder, how much pressure you have to apply for a release of H2S? Would the pressure of a strong wind on the façade do the trick? Imagine a house that farts when the wind blows......

As Buzz Aldrin would say 'bout as welcome as a fart in a space suit'.
