Explanation:
Methane gas, which may be present in confined spaces such as a basement, can cause death by asphyxiation.
<h3>
What are the dangers of methane gas in confined space?</h3>
Low amounts are safe for inhalation. A significant amount can replace oxygen in the atmosphere. Reduced oxygen availability can cause symptoms like weariness, emotional instability, fast breathing, and rapid heart rate. Insufficient oxygen can cause nausea, vomiting, collapse, convulsions, coma. The onset of symptoms is accelerated by physical activity. Organs including the heart and brain can suffer long-term damage from a lack of oxygen.
Contact with Skin: Not irritating. The skin might become chilled or frozen when in direct touch with the liquid gas (frostbite). Itching and numbness are signs of mild frostbite. Burning and rigidity are signs of more serious frostbite.
No evidence of carcinogenicity.

The glass (which does not crystallize even though it is accepted) of a window is NOT a mineral, since it is neither a substance of natural origin (although it is manufactured from natural components) nor does it have a defined crystalline structure, that is, the atoms they are not arranged in an orderly and regular way along axes and planes forming flat faces that keep a symmetry.
Remember that a mineral is defined as a solid, inorganic, homogeneous substance, of natural origin, with a crystalline structure and a determined and well-defined chemical composition within narrow margins and that has regular and characteristic physical properties.
