International Chemical Safety Cards ISOPROPYL CHLOROFORMATE ICSC: 0287 ISOPROPYL CHLOROFORMATE Isopropyl chlorocarbonate Chloroformic acid, isopropyl ester Carbonochloridic acid 1-methylethyl ester C4H7ClO2/(CH3)2CHOCOCl Molecular mass: 122.6 CAS # 108-23-6 RTECS # LQ6475000 ICSC # 0287 UN # 2407 TYPES OF HAZARD/ EXPOSURE ACUTE HAZARDS/ SYMPTOMS PREVENTION FIRST AID/ FIRE FIGHTING FIRE Highly flammable. Gives off irritating or toxic fumes (or gases) in a fire. NO open flames, NO sparks, and NO smoking. Powder, AFFF, foam, carbon dioxide, alcohol-resistant foam. EXPLOSION Vapour/air mixtures are explosive. Closed system, ventilation, explosion-proof electrical equipment and lighting. In case of fire: keep drums, etc., cool by spraying with water.   EXPOSURE AVOID ALL CONTACT! INHALATION Burning sensation. Cough. Laboured breathing. Ventilation, local exhaust, or breathing protection. Fresh air, rest. Half-upright position. Artificial respiration if indicated. Refer for medical attention. SKIN Redness. Pain. Blisters. Serious frostbite. Protective clothing. Remove contaminated clothes. Rinse and then wash skin with water and soap. Refer for medical attention. EYES Redness. Pain. Severe deep burns. Face shield or eye protection in combination with breathing protection. First rinse with plenty of water for several minutes (remove contact lenses if easily possible), then take to a doctor. INGESTION Abdominal cramps. Burning sensation. Weakness. Do not eat, drink, or smoke during work. Rinse mouth. Do NOT induce vomiting. Refer for medical attention. SPILLAGE DISPOSAL STORAGE PACKAGING & LABELLING Collect leaking and spilled liquid in sealable containers as far as possible. Absorb remaining liquid in sand or inert absorbent and remove to safe place. Do NOT wash away into sewer (extra personal protection: complete protective clothing including self-contained breathing apparatus). Fireproof. Separated from acids, iron, food and feedstuffs. Cool. Well closed. Unbreakable packaging; put breakable packaging into closed unbreakable container. Do not transport with food and feedstuffs.

International Chemical Safety Cards ISOPROPYL CHLOROFORMATE ICSC: 0287 I M P O R T A N T D A T A PHYSICAL STATE; APPEARANCE: COLOURLESS LIQUID , WITH PUNGENT ODOUR. PHYSICAL DANGERS: The vapour is heavier than air and may travel along the ground; distant ignition possible. CHEMICAL DANGERS: May explode on heating. The substance decomposes on heating or on contact with acids producing toxic and corrosive fumes including chlorine and phosgene. Hydrolyzes readily in the presence of water or moist air. OCCUPATIONAL EXPOSURE LIMITS (OELs): TLV not established. ROUTES OF EXPOSURE: The substance can be absorbed into the body by inhalation of its vapour and by ingestion. INHALATION RISK: No indication can be given about the rate in which a harmful concentration in the air is reached on evaporation of this substance at 20°C. EFFECTS OF SHORT-TERM EXPOSURE: The substance is corrosive to the eyes, the skin and the respiratory tract. Corrosive on ingestion. Inhalation of vapour may cause lung oedema (see Notes). The effects may be delayed. Medical observation is indicated. See Notes. EFFECTS OF LONG-TERM OR REPEATED EXPOSURE: PHYSICAL PROPERTIES Boiling point: 104.6°C Relative density (water = 1): 1.08 Solubility in water: none Relative vapour density (air = 1): 4.2 Flash point: 15.6°C Auto-ignition temperature: >500°C Explosive limits, vol% in air: 4-15

ENVIRONMENTAL DATA
N O T E S
Environmental effects from the substance have not been investigated. The symptoms of lung oedema often do not become manifest until a few hours have passed and they are aggravated by physical effort. Rest and medical observation are therefore essential. Immediate administration of an appropriate spray, by a doctor or a person authorized by him/her, should be considered. Insufficient data are available on the effect of this substance on human health, therefore utmost care must be taken. Transport Emergency Card: TEC (R)-30G33
