Nitrous oxide – N2O

Main information on nitrous oxide N2O or laughing gas: physical characteristics, health effects, dedicated detection equipment (N2O gas detector) and respiratory protection.

Nitrous oxide detector and N2O respiratory protection

Main characteristics of nitrous oxide

Nitrous oxide is also known as laughing gas. It is a strong greenhouse gas (global warming potential of 298), notably through agro-industrial activities (nitrogen fertilization), wastewater treatment and the combustion of organic and fossil materials. Nitrous oxide is an oxidizer used in combustion engines. N2O is also used as a numbing agent by doctors and veterinarians.

Nitrous oxide effects on health

N2O is a colorless gas, spreading a slightly sweet odor. It is an anesthetic and neurotoxic gas that can have many harmful effects on health. It can trigger hallucinations, disorientation, muscle spasms, intoxication, and death from asphyxiation.

Nitrous oxide is also an oxidizing gas which promotes combustion and increases the danger of fire in some configurations.

N2O detector (nitrous oxide)

Measurement of N2O concentrations can be performed using a nitrous oxide detector. This gas can be measured in toxicity (ppm) or in explosivity (% LEL) depending on the applications.
