It is also known as oxygen toxicity syndrome, oxygen intoxication, and oxygen poisoning. Historically, the central nervous system condition was called the Paul Bert effect, and the pulmonary condition the Lorrain Smith effect, after the researchers who pioneered its discovery and description in the late 19th century. Severe cases can result in cell damage and death, with effects most often seen in the central nervous system, lungs and eyes. Oxygen toxicity is a concern for underwater divers, those on high concentrations of supplemental oxygen (particularly premature babies), and those undergoing hyperbaric oxygen therapy.

To open-carry a handgun in a vehicle (e.g, car, bus, etc...) a person must have a valid concealed pistol license. The county sheriff or city police chief shall issue a concealed pistol license to any applicant, age 21 or older, who meets certain requirements, including no felony convictions, no misdemeanor domestic violence convictions, and no outstanding warrants. Open carrying of firearms is not prohibited by law, although trouble with some law enforcement agencies has been encountered while open carrying in the past, most notably in a case in Ellensburg, Washington.
