2. HAZARDS IDENTIFICATION

Emergency Overview Very toxic by inhalation, in contact with skin and if swallowed. May cause burns of eyes, skin and mucous membranes. DANGER! Liquified, nonflammable gas under pressure. A greenish-yellow gas or amber liquid with a pungent odor. Immediately dangerous to life and health (IDLH) concentration = 10 ppm. Appearance Amber liquid; green-yellow gas

Physical State Liquid or gas

Odor Pungent

Potential Health Effects Acute Toxicity Skin

Causes burns. Chlorine vapors can cause irritation, burning and blisters.

Inhalation

Inhalation is the major potential route of exposure. Chlorine is a respiratory irritant. Chlorine is irritating and can be corrosive to the eyes, skin, and mucous membranes. Symptoms of exposure include burning of eyes, nose, and mouth. Other symptoms of overexposure can include nausea, vomiting, dizziness, shortness of breath and chest pain. Exposures to higher concentrations can cause unconsciousness and death. Pulmonary edema and chemical pneumonia can develop and may occur hours after exposure. Chlorine has an IDLH (Immediately Dangerous to Life or Health) concentration of 10 ppm.

Ingestion

Chlorine is gas at room temperature. Ingested liquid chlorine can cause severe burns of mouth, esophagus and stomach. Nausea and vomiting are likely to occur.

Eyes

Chronic Toxicity Numerous studies have been conducted to determine the potential chlorine has to cause chronic effects. In rats exposed to concentrations up to 9 ppm for 6 hours a day, 5 days a week for 6 weeks, decreases in body weight and inflammation of the respiratory tract were observed. At exposures of 3 and 9 ppm, changes in the liver and kidneys were also noted. Rabbits and guinea pigs exposed to 1.7 ppm for 9 months showed weight loss and a decreased resistance to disease. No adverse effects were observed in rabbits and guinea pigs at levels of 0.7 ppm. Guinea pigs exposed to 1.6 ppm for 5 hours a day, for 47 days and injected with tuberculosis (bacteria) displayed shorter life cycles, than those exposed to just one of the agents. Rats with pulmonary disease showed an increased response to chlorine. Rhesus monkeys exposed to concetrations up to 2.3 ppm for 6 hours a day, 5 days a week for one year did not exhibit any signs of chronic toxicity, except for eye irritation. A study of 600 diphragm cell workers from 25 plants with an average duration of exposure of 11 years exposed to 0.006 to 1.42 ppm, showed no statistically significant increase in abnormal chest x-rays, EKGs or pulmonary function tests.

Chronic effects

Aggravated Medical Conditions

6. ACCIDENTAL RELEASE MEASURES Personal Precautions

Ensure adequate ventilation.

Methods for Containment

Prevent further leakage or spillage if safe to do so. Use dyking or absorbant to prevent run-off from entering waterways.

Methods for Cleaning Up

Pick up and transfer to properly labeled containers.

Other information

Evacuate unprotected personnel upwind or crosswind for at least 200 feet (300 feet for large spills) out of danger area. Wear one-piece, total encapsulating suite of Butyl coated nylon or equivalent with self-contained breating apparatus. Isolate leak to whatever extent possible. If a chlorine container is leaking, try to position it so that gas rather than liquid leaks; apply emergency kit device if possible. For other than minor leaks, immediately implement predetermined emergency plan.

7. HANDLING AND STORAGE Handling

Avoid contact with skin and avoid breathing vapors. Use only with adequate ventilation. Do not get in eyes or on skin or on clothing. Wash thoroughly after handling. Do not eat, drink, or smoke in work area. Wash hands prior to eating, drinking, or using restroom. Any clothing or shoes which become contaminated with chlorine should be removed immediately and thoroughly laundered before wearing again. Follow protective controls set forth in Section 8 when handling this product. Vapors are heavier than air and will collect in low areas. Do not enter confined spaces such as tanks or pits without following proper entry procedures as required by 29 CFR 1910.146.

Storage

Keep away from heat and open flame. Store properly labeled containers in a cool, dry, well-ventilated area away from incompatible materials (See Section 10) and away from basements, pits, etc. Isolate from acetylene, ammonia, hydrogen, hydrocarbons, ether, turpentine, and finely divided metals. Make daily inspections for leaks. Room vents should be located at floor level. Do not apply heat to a chlorine container. Do not remove or deface label or tags. Chlorine piping and equipment must be thoroughly cleaned of organics and moisture before use. Keep chlorine piping and handling equipment clean and dry. Liquid chlorine lines must have suitable expansion chambers between block valves due to the high coefficient of expansion. INCOMPATIBLE MATERIALS FOR STORAGE OR TRANSPORT Dry chlorine will react violently with titanium. Dry chlorine will also react with aluminum and tin. Moist chlorine will react with most metals. Stainless steel can fail due to chloride ion stress corrosion cracking if used in the presence of moisture.

11. TOXICOLOGICAL INFORMATION Acute Toxicity Product information

Concentrations of 3-6 ppm can cause irritation of the nose and mucous membrane of the upper respiratory tract followed by headache and coughing. 10 ppm can cause severe irritation of respiratory tract with 15-20 ppm causing intense cough. Exposures to concentrations above 25 ppm can cause unconsciousness and death. Exposure to humans to 0.5 ppm for 8 hours and 1 ppm for 4 hours have caused transient decreased pulmonary capacity, as measured by pulmonary function tests. In persons exposed to acute, non-lethal levels, decreased pulmonary capacity is followed by a gradual return to normal. In some cases long lasting effects have been observed.
