Humans can smell chlorine gas at ranges from 0.1–0.3 ppm. According to a review from 2010: "At 1–3 ppm, there is mild mucous membrane irritation that can usually be tolerated for about an hour. At 5–15 ppm, there is moderate mucous membrane irritation. At 30 ppm and beyond, there is immediate chest pain, shortness of breath, and cough.
[1] [2] Smoke, chlorine, phosgene, sulfur dioxide, hydrogen chloride, hydrogen sulfide, nitrogen dioxide, ozone, and ammonia are common irritants. Depending on the type and amount of irritant gas inhaled, victims can experience symptoms ranging from minor respiratory discomfort to acute airway and lung injury and even death.
Chlorine dioxide is approximately 10 times more soluble in water than elemental chlorine [1] but its solubility is very temperature-dependent. At partial pressures above 10 kPa (1.5 psi) [1] (or gas-phase concentrations greater than 10% volume in air at STP) of ClO 2 may explosively decompose into chlorine and oxygen. The decomposition can be ...

Summer 2023 saw record-breaking heat, and, according to the Centers of Disease Control and Prevention, 90% of the 120,000 heat-related emergency room visits in the United States last year took ...
Space heaters are repeatedly linked with tragedies. Local fire departments responded to an estimated average of 44,210 home structure fires caused by heating equipment, including space heaters ...
A feasibility study of the ozone formed from the oxidation of nitrogen dioxide in ambient air reported by the WHO suggested that daily deaths of 1 to 2% is attributed to exposure to ozone concentration above 47.3 ppb and exposure above 75.7 ppb is attributed to 3 to 5% increase in daily mortality. A level of 114 ppb was attributed to 5 to 9% ...
