Toxic gas can be harmful to humans when inhaled or ingested in various quantities. Toxic gases include gases such as ammonia, chlorine, sulphur, and many others. The official description of a toxic gas is: “A compressed gas or vapor that has a median lethal concentration (LC50) in air of 200 parts per million (ppm) by volume, or 2 milligrams per liter of mist, fume, or dust, when administered by continuous inhalation for one hour (or less if death occurs within one hour) to albino rats weighing between 200 and 300 grams each.” The skull and cross-bones is a globally used symbol to indicate toxic substances. At SEMA Gases we have several high-quality toxic gasses able for calibration or testing. Contact us for the possibilities.
