    Concentrated Formic Acid slowly decomposes to carbon monoxide and water and the pressure built up can cause an explosion of the sealed glass bottle.
    As a safety measure we fit larger glass bottles with a closure featuring a venting valve. Bottles with a non-vented closure should have pressure released regularly.
