    The specific guidelines for prevention of asphyxiation due to displacement of oxygen by asphyxiant gases is covered under CGA's pamphlet SB-2, Oxygen-Deficient Atmospheres. [15] Specific guidelines for use of gases other than air in back-up respirators is covered in pamphlet SB-28, Safety of Instrument Air Systems Backed Up by Gases Other Than Air.

    Highly Toxic: a gas that has a LC 50 in air of 200 ppm or less. [2] NFPA 704: Materials that, under emergency conditions, can cause serious or permanent injury are given a Health Hazard rating of 3. Their acute inhalation toxicity corresponds to those vapors or gases having LC 50 values greater than 1,000 ppm but less than or equal to 3,000 ppm ...

  4. Methanol fuel - Wikipedia

    en.wikipedia.org/wiki/Methanol_fuel

    Methanol (CH 3 OH) is less expensive to sustainably produce than ethanol fuel, although it is more toxic than ethanol and has a lower energy density than gasoline. Methanol is safer for the environment than gasoline, is an anti-freeze agent, prevents dirt and grime buildup within the engine, has a higher ignition temperature and can withstand ...

  5. Alcohol intoxication - Wikipedia

    en.wikipedia.org/wiki/Alcohol_intoxication

    Acute alcohol poisoning is a medical emergency due to the risk of death from respiratory depression or aspiration of vomit if vomiting occurs while the person is unresponsive. Emergency treatment strives to stabilize and maintain an open airway and sufficient breathing while waiting for the alcohol to metabolize.

  6. Methanol - Wikipedia

    en.wikipedia.org/wiki/Methanol

    Methanol is a promising energy carrier because, as a liquid, it is easier to store than hydrogen and natural gas. Its energy density is, however, lower than methane, per kg. Its combustion energy density is 15.6 MJ/L , whereas that of ethanol is 24 and gasoline is 33 MJ/L.

  7. Nitrous oxide - Wikipedia

    en.wikipedia.org/wiki/Nitrous_oxide

    Nitrous oxide is a weak general anaesthetic, and so is generally not used alone in general anaesthesia, but used as a carrier gas (mixed with oxygen) for more powerful general anaesthetic drugs such as sevoflurane or desflurane. It has a minimum alveolar concentration of 105% and a blood/gas partition coefficient of 0.46. The use of nitrous ...

    However, they are usually unwanted in oils, and therefore likely fuels, due to their environmental toxicity and tendency to cause catalyst poisoning and corrosion during oil production and refining. [5] Alcohols: Methanol (MeOH) Ethanol (EtOH); see also Common ethanol fuel mixtures; Isopropyl alcohol (IPA) n-Butanol (BuOH) Gasoline grade tert ...
