Acethylene (C2H2) – also known as Ethyne – is a compound from the alkynes group. This gas is oftentimes used in the chemical industry as base material in organic compounds synthesis (such as acrylate or chloroethylene). Acetylene is also used during hydrocarbon cracking process (petroleum refining) and while welding with temperatures up to 3,000°C.

Acetylene effects on health
At ambient temperature, ethyne is a colorless and theoretically odorless (when it is a pure gas). Even if this gas is not toxic, respiratory hazards may lead to suffocation. It is extremely flammable (R12) and features risks of explosion (R5) with or without air contact (R6). It basically reacts with almost any oxidizer and can compose toxic and/or corrosive gas mixtures even at low concentrations.
