General advice

Consult a physician. Show this safety data sheet to the doctor in attendance.

If inhaled

Fresh air, rest.

In case of skin contact

Remove contaminated clothes. Rinse and then wash skin with water and soap.

In case of eye contact

Rinse with plenty of water for several minutes (remove contact lenses if easily possible). Refer for medical attention.

If swallowed

Rinse mouth. Refer for medical attention .

4.2 Most important symptoms/effects, acute and delayed

Compound is a powerful narcotic and liver poison; may also cause changes in blood composition and neurological disturbances. Repeated exposure by inhalation can be fatal. Ingestion causes vomiting, diarrhea, severe mucosal injury, liver necrosis, cyanosis, unconsciousness, loss of reflexes, and death. Contact with eyes causes irritation and lachrymation. Can be absorbed through the skin and may produce severe skin lesions. (USCG, 1999)

4.3 Indication of immediate medical attention and special treatment needed, if necessary

Immediate first aid: Ensure that adequate decontamination has been carried out. If patient is not breathing, start artificial respiration, preferably with a demand-valve resuscitator, bag-valve-mask device, or pocket mask, as trained. Perform CPR as necessary. Immediately flush contaminated eyes with gently flowing water. Do not induce vomiting. If vomiting occurs, lean patient forward or place on left side (head-down position, if possible) to maintain an open airway and prevent aspiration. Keep patient quiet and maintain normal body temperature. Obtain medical attention. /Military Smoke Agents/

5.Fire-fighting measures

5.1 Extinguishing media

Suitable extinguishing media

If material involved in fire: Extinguish fire using agent suitable for type of surrounding fire. (Material itself does not burn or burns with difficulty.) Use water in flooding quantities as fog. Cool all affected containers with flooding quantities of water. Apply water from as far a distance as possible.

5.2 Specific hazards arising from the chemical

Special Hazards of Combustion Products: Irritating hydrogen chloride vapor may form in fire. (USCG, 1999)

5.3 Special protective actions for fire-fighters

Wear self-contained breathing apparatus for firefighting if necessary.

6.Accidental release measures

6.1 Personal precautions, protective equipment and emergency procedures

Use personal protective equipment. Avoid dust formation. Avoid breathing vapours, mist or gas. Ensure adequate ventilation. Evacuate personnel to safe areas. Avoid breathing dust. For personal protection see section 8.

6.2 Environmental precautions

Personal protection: particulate filter respirator adapted to the airborne concentration of the substance. Do NOT let this chemical enter the environment. Sweep spilled substance into covered containers. Carefully collect remainder. Then store and dispose of according to local regulations.

6.3 Methods and materials for containment and cleaning up

1. Ventilate area of spill; 2. Collect spilled material in the most convenient and safe manner for reclamation or for disposal. ... Liquid containing hexachloroethane should be absorbed in vermiculite, dry sand, earth or a similar material.

7.Handling and storage

7.1 Precautions for safe handling

Avoid contact with skin and eyes. Avoid formation of dust and aerosols. Avoid exposure - obtain special instructions before use.Provide appropriate exhaust ventilation at places where dust is formed. For precautions see section 2.2.

7.2 Conditions for safe storage, including any incompatibilities

Separated from strong oxidants, alkali metals and food and feedstuffs. See Chemical Dangers. Store in an area without drain or sewer access. Provision to contain effluent from fire extinguishing....Hexachloroethane must be stored to avoid contact with hot iron, zinc, aluminum, and alkalis, since violent reactions occur. Store in tightly closed containers in a cool, well-ventilated area away from heat.

8.Exposure controls/personal protection

8.1 Control parameters

Occupational Exposure limit values

Recommended Exposure Limit: 10 Hr Time-Weighted Avg: 1 ppm (10 mg/cu m), skin.

NIOSH considers hexachloroethane to be a potential occupational carcinogen.

NIOSH considers ethylene dichloride; hexachloroethane; 1,1,2,2-tetrachloroethane; and 1,1,2-trichloroethane; to be potential occupational carcinogens. Additionally, NIOSH recommends that the other five chloroethane compounds: 1,1-dichloroethane; ethyl chloride; methyl chloroform; pentachloroethane; and 1,1,1,2-tetrachloroethane be treated in the workplace with caution because of their structural similarity to the four chloroethanes shown to be carcinogenic in animals.

Biological limit values

no data available

8.2 Appropriate engineering controls

Handle in accordance with good industrial hygiene and safety practice. Wash hands before breaks and at the end of workday.

8.3 Individual protection measures, such as personal protective equipment (PPE)

Eye/face protection

Safety glasses with side-shields conforming to EN166. Use equipment for eye protection tested and approved under appropriate government standards such as NIOSH (US) or EN 166(EU).

Skin protection

Wear impervious clothing. The type of protective equipment must be selected according to the concentration and amount of the dangerous substance at the specific workplace. Handle with gloves. Gloves must be inspected prior to use. Use proper glove removal technique(without touching glove's outer surface) to avoid skin contact with this product. Dispose of contaminated gloves after use in accordance with applicable laws and good laboratory practices. Wash and dry hands. The selected protective gloves have to satisfy the specifications of EU Directive 89/686/EEC and the standard EN 374 derived from it.

12.1 Toxicity

  • Toxicity to fish: LC50; Species: Lepomis macrochirus (Bluegill, 0.7 g); Conditions: freshwater, flow through, 17.3°C, pH 7.1-7.8), hardness 44.4 mg/L CaCO3 (40.7-46.6 mg/L CaCO3), alkalinity 45.4 mg/L CaCO3 (42.3-57.0 mg/L CaCO3), dissolved oxygen 6.7 mg/L (4.0-8.4 mg/L); Concentration: 1820 ug/L for 24 hr
  • Toxicity to daphnia and other aquatic invertebrates: LC50 Daphnia magna 2.9 mg/L/48 hr /Conditions of bioassay not specified/.
  • Toxicity to algae: no data available
  • Toxicity to microorganisms: no data available

12.2 Persistence and degradability

AEROBIC: Hexachloroethane at 100 mg/L achieved 0% of its theoretical BOD using an activated sludge inoculum at 30 mg/L over a 2 week incubation period and the Japanese MITI test(1). The biodegradation half-life of hexachloroethane in a non-adapted aerobic sandy soil was reported as 25-48 days(2).

12.3 Bioaccumulative potential

Bioconcentration factors of 139, 708, and 510 were measured for hexachloroethane in bluegill sunfish(1), fathead minnows(2) and rainbow trout(3), respectively. BCF values of 1.4-8.5 and 1.0-6.8 have been measured for hexachloroethane at 5 ug/L and 0.5 ug/L in carp(4). According to a classification scheme(5), BCF values of zero to 30 indicate the potential for bioconcentration in aquatic organisms are low and from 100 to 1,000 are high(SRC).

12.4 Mobility in soil

Measured Koc values ranging from 1,380 to 2,360 have been reported for hexachloroethane(1,2). According to a classification scheme(3), this range of Koc values suggests that hexachloroethane is expected to have low to slight mobility in soil.

12.5 Other adverse effects

no data available

13.Disposal considerations

13.1 Disposal methods

Product

The material can be disposed of by removal to a licensed chemical destruction plant or by controlled incineration with flue gas scrubbing. Do not contaminate water, foodstuffs, feed or seed by storage or disposal. Do not discharge to sewer systems.
