3-chloro-2-methylpropene	3-chloro-2-methylpropene	563-47-3	209-251-2	100%

SECTION 4: First-aid measures

4.1 Description of necessary first-aid measures

If inhaled

Fresh air, rest. Half-upright position. Artificial respiration may be needed. Refer for medical attention.

Following skin contact

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

Following eye contact

First rinse with plenty of water for several minutes (remove contact lenses if easily possible), then refer for medical attention.

Following ingestion

Rinse mouth. Do NOT induce vomiting. Rest. Refer for medical attention .

4.2 Most important symptoms/effects, acute and delayed

Inhalation causes irritation of nose and throat. Contact of vapor or liquid with eyes causes irritation. Liquid irritates skin. Ingestion causes irritation of mouth and stomach. (USCG, 1999)

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

Absorption, Distribution and Excretion

2-(14)C 3-Chloro-2-methylpropene (specific activity, 2.5 mCi/umol; radiochemical purity, 93%; 5% 1-chloro-2-methylpropene) was administered by gavage to male Fischer 344 rats as single or up to four daily doses of 150 mg/kg body weight in corn oil. The compound was extensively absorbed and rapidly excreted: 82% of the single dose was eliminated within 24 hours after treatment. It was rapidly distributed to tissues, and the highest concentrations were found in forestomach, liver and kidney; the concentration of radiolabel was considerably lower in glandular stomach than in forestomach. The tissue concentrations were approximately doubled after two doses, but little additional increase was observed after four doses. The concentrations decreased after cessation of treatment. After a single dose, about 58% of the administered radiolabel was found in the urine, 22% was exhaled and 2% was detected in the feces. In the expired air, about 12% of the dose was (14)C-carbon dioxide and 7% was volatile compounds.

SECTION 5: Fire-fighting measures

5.1 Suitable extinguishing media

Do not extinguish fire unless flow can be stopped. Use water in flooding quantities as fog because solid streams of water may spread fire. Cool all affected containers with flooding quantities of water, being sure to apply water from as far a distance as possible. Use alcohol foam, carbon dioxide or dry chemical.

5.2 Specific hazards arising from the chemical

Special Hazards of Combustion Products: Irritating and toxic hydrogen chloride and phosgene vapors may be formed. Behavior in Fire: Vapor is heavier than air and may travel considerable distance to a source of ignition and flash back. (USCG, 1999)

5.3 Special protective actions for fire-fighters

Use powder, carbon dioxide, foam. In case of fire: keep drums, etc., cool by spraying with water.

SECTION 6: Accidental release measures

6.1 Personal precautions, protective equipment and emergency procedures

Evacuate danger area! Consult an expert! Personal protection: chemical protection suit including self-contained breathing apparatus. Remove all ignition sources.

Do NOT wash away into sewer. Do NOT let this chemical enter the environment.

6.2 Environmental precautions

Evacuate danger area! Consult an expert! Personal protection: chemical protection suit including self-contained breathing apparatus. Remove all ignition sources.
