1-BROMO-3-CHLOROPROPANE ICSC: 1665 1-Chloro-3-bromopropane Trimethylene chlorobromide C3H6BrCl / Cl(CH2)3Br Molecular mass: 157.4 ICSC #    1665 CAS #     109-70-6 RTECS # TX4113000 UN #        2688 Types of Hazard/ Exposure Acute Hazards/ Symptoms Prevention First Aid/ Fire Fighting FIRE Flammable. Gives off irritating or toxic fumes (or gases) in a fire. NO open flames, NO sparks, and NO smoking. Powder , water spray , foam , carbon dioxide . Explosion Above 57°C explosive vapour/air mixtures may be formed. Above 57°C use a closed system, ventilation, and explosion-proof electrical equipment. In case of fire: keep drums, etc., cool by spraying with water. Exposure  •Inhalation Tremor. Drowsiness. Ventilation, local exhaust, or breathing protection. Fresh air, rest. Refer for medical attention.  •Skin Protective gloves. Remove contaminated clothes. Rinse and then wash skin with water and soap.  •Eyes Safety spectacles . Rinse with plenty of water (remove contact lenses if easily possible).  •Ingestion (see Inhalation). Do not eat, drink, or smoke during work. Rinse mouth. Refer for medical attention. Spillage Disposal Storage Packaging & Labelling Personal protection: filter respirator for organic gases and vapours adapted to the airborne concentration of the substance. Do NOT let this chemical enter the environment. Collect leaking liquid in sealable containers. Absorb remaining liquid in sand or inert absorbent and remove to safe place. Separated from food and feedstuffs. Well closed. Store in an area without drain or sewer access. Do not transport with food and feedstuffs. UN Hazard Class: 6.1 UN Packing Group: III Signal: Danger Flame-Skull-Health haz Flammable liquid and vapour Harmful if swallowed May be harmful in contact with skin Toxic if inhaled May cause damage to central nervous system and liver Harmful to aquatic life 1-BROMO-3-CHLOROPROPANE ICSC: 1665 Important Data Physical State; Appearance: COLOURLESS LIQUID . Physical Dangers: Chemical Dangers: The substance decomposes on burning producing toxic and corrosive gases including hydrogen bromide (See ICSC 0282). and hydrogen chloride (See ICSC 0163). Occupational Exposure Limits: TLV not established. MAK 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 may cause effects on the central nervous system and liver , resulting in impaired functions . o human data. But structural analogy gives suspicion to CNS effects, corroborated by animal oral application of 900 mg/kg: exicitation, followed by sleepiness and muscular weaknes. Effects of Long-Term or Repeated Exposure: Physical Properties Boiling point: 143.3°C Melting point: -58.9°C Relative density (water = 1): 1.6 Solubility in water, g/100 ml at 25°C: 0.224 Vapour pressure, kPa at 25°C: 0.85 Relative vapour density (air = 1): 5.4 Relative density of the vapour/air-mixture at 20°C (air = 1): 1.03 Flash point: 57°C Explosive limits, vol% in air: 3.2 - 8.6 Octanol/water partition coefficient as log Pow: 2.18 Environmental Data The substance is harmful to aquatic organisms.
