There is no antidote for chlorine toxicity. Immediately remove the patient/victim from the source of exposure. Immediately decontaminate eyes with large amounts of tepid water for at least 15 minutes. Seek medical attention immediately.
Two forms of vitamin C, ascorbic acid and sodium ascorbate, will neutralize chlorine. Neither is considered a hazardous chemical.
Chlorine gas can stay in the air for just a few minutes to several hours. It depends on the size and ventilation of the area as well as the amount of gas present. Open windows and doors to let in fresh air.
Treatment of chlorine gas exposure is mostly supportive. Removal of the individual from the contaminated environment is the first step of management. Clinicians will assess the patient's airway, breathing, and circulation and provide humidified oxygen as necessary. Severe exposures may require endotracheal intubation.
Victims exposed only to chlorine gas who have no skin or eye irritation do not need decontamination. They may be transferred immediately to the Support Zone. All others require decontamination. Rescue personnel are at low risk of secondary contamination from victims who have been exposed only to chlorine gas.
Sodium hydroxide (caustic soda) is normally used in the absorption of chlorine containing gases. When chlorine reacts with the caustic salt is formed. Salt has limited solubility in scrubber solutions.
► Exposure to Chlorine can cause headache, dizziness, nausea and vomiting. ► Repeated exposure can lead to permanent lung damage. OSHA: The legal airborne permissible exposure limit (PEL) is 1 ppm, not to be exceeded at any time.
The body does not absorb chlorine well. However, small amounts can pass through the skin when people are exposed to chlorine gas, chlorine bleach, or bathing in water with high levels of chlorine. Lower levels of exposure can occur when people handle soil or water containing chlorine.
Yet even when chlorine gas has fully dissipated from a space, the area may not be completely safe. This is because it can settle on surfaces or be absorbed into materials like clothing and carpets. Such materials may then continue to release chlorine gas into the air and remain a health risk.
Typically, if left exposed to air in an open container, chlorine will naturally dissipate within a few hours to a day. Boiling water for 15 minutes also helps to remove chlorine as it causes the chlorine to evaporate.
In a well-ventilated area, bleach fumes dissipate faster, sometimes within just a few hours. In contrast, the smell can linger for days in a closed-off room with no airflow.
Vitamin C effectively neutralizes chlorine and is safer to handle than sulfur-based dechlorination chemicals. The sodium ascorbate form of vitamin C has less affect on pH than the ascorbic acid form.
Nebulized sodium bicarbonate may be another adjunctive treatment for chlorine pulmonary exposures. Theoretically, inhaled bicarbonate can neutralize hypochlorous and hydrochloric acids, decreasing severity of lung injury.
If the chlorine release was indoors, get out of the building. If the chlorine release was from household cleaners or chemicals, open windows and doors to let in fresh air. Leave the area until the gas has gone away.
Chlorine irritates the skin and can cause burning pain, inflammation, and blisters. Exposure to liquefied chlorine can result in frostbite. There is no specific antidote for chlorine poisoning.
Short-term exposure to chlorine in air
throat irritation at 5-15 ppm. immediate chest pain, vomiting, changes in breathing rate, and cough at 30 ppm. lung injury (toxic pneumonitis) and pulmonary edema (fluid in the lungs) at 40-60 ppm. death after 30 minute exposure to 430 ppm.
Chlorine poisoning is a medical emergency. If a person swallows or inhales a chlorine-based product and shows symptoms of poisoning, contact the emergency services or go to the hospital immediately. In the United States, a person can also contact the National Poison Control helpline on 1-800-222-1222 for advice.
Ascorbic acid or sodium ascorbate, in essence Vitamin C, neutralizes the chlorine. It's the main ingredient in commercial chlorine removers.
Nebulized lidocaine (4% topical solution) may provide analgesia and reduce coughing. Other medications that may be used in the treatment of chlorine gas exposure include nebulized sodium bicarbonate and inhaled or systemic corticosteroids; however, evidence of efficacy is mixed.
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.
General. Chlorine has a characteristic penetrating and irritating odor. The gas is greenish yellow in color and the liquid is clear amber.
In case of large leak absorb the chlorine in caustic solution or soda solution or lime solution scrubber. - Treat area for frostbite and chemical exposure with a continuous stream of water for 20 minutes and seek medical attention. Chlorine is very corrosive and reacts with body moisture to form corrosive acid.
