Toxicity to chlorine gas depends on the dose and duration of exposure. At concentrations of 1 to 3 ppm chlorine gas acts as an eye and oral mucous membrane irritant, at 15 ppm there is an onset of pulmonary symptoms, and it can be fatal at 430 ppm within 30 minutes.[1]
Because of its strong odor, chlorine gas can be detected easily. Symptoms of chlorine gas exposure include burning of the conjunctiva, throat, and the bronchial tree. Higher concentrations can produce bronchospasm, lower pulmonary injury, and delayed pulmonary edema.
Оно што је битно је да у затвореним просторијама буде добро проветравање:
Chlorine gas can be used as a disinfecting agent at swimming pools, or it could form by mixing household agents. The combination of bleach (sodium hypochlorite) with acid produces chlorine gas, a heavy green-yellow gas with a strong odor. Chlorine gas has also been used as an industrial solvent and has other industrial uses such as the production of bulk materials, bleached paper products, plastics such as PVC, and solvents. Chlorine gas is also used to make dyes, textiles, paint, and even medications.
Chlorine gas is pressurized and cooled for easy storage in liquid form. When released, the liquid form of chlorine quickly turns into yellow-green colored gas with an irritating odor. Since chlorine is heavier than air, it accumulates in low-lying areas.
Важно је то што се лако осети, већ у концентрацијама које нису генерално опасне.
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. At approximately 40–60 ppm, a toxic pneumonitis and/or acute pulmonary edema can develop. Concentrations of about 400 ppm and beyond are generally fatal over 30 minutes, and at 1,000 ppm and above, fatality ensues within only a few minutes."
Из горе наведеног, не верујем да можете да направите већу штету средствима на бази хипохлорита уколико их примењујете рационално, према упутствима, уз проветравање просторија, уколико се ради у затвореном простору. Неко суров би приметио да није лоше имати кућног љубимца, као индикатор, али мени то никада не би пало на памет.
