Value As written Source – Allyl chloride appears as a clear colorless liquid with an unpleasant pungent odor. Flash point -20 °F. Boiling point 113 °F. Less dense than water (7.8 lb / gal) and insoluble in water. Hence floats on water. Vapor irritates skin, eyes and mucous membranes. Vapors are heavier than air. Long exposure to low concentrations or short exposure to high concentrations may have adverse health effects from inhalation or skin absorption.

First aid
- Eyes: First check the victim for contact lenses and remove if present. Flush victim's eyes with water or normal saline solution for 20 to 30 minutes while simultaneously calling a hospital or poison control center. Do not put any ointments, oils, or medication in the victim's eyes without specific instructions from a physician. Immediately transport the victim after flushing eyes to a hospital even if no symptoms (such as redness or irritation) develop. Skin: Immediately flood affected skin with water while removing and isolating all contaminated clothing.[1]
- General First Aid: · Call 911 or emergency medical service. · Ensure that medical personnel are aware of the material(s) involved, take precautions to protect themselves and avoid contamination. · Move victim to fresh air if it can be done safely. · Administer oxygen if breathing is difficult. · If victim is not breathing: -- DO NOT perform mouth-to-mouth resuscitation; the victim may have ingested or inhaled the substance. -- If equipped and pulse detected, wash face and mouth, then give artificial respiration using a proper respiratory medical device (bag-valve mask, pocket mask equipped…[10]
- (General first aid procedures) Eye: Irrigate immediately - If this chemical contacts the eyes, immediately wash (irrigate) the eyes with large amounts of water, occasionally lifting the lower and upper lids. Get medical attention immediately. Skin: Soap wash immediately - If this chemical contacts the skin, immediately wash the contaminated skin with soap and water.[5]
- Fresh air, rest. Half-upright position. Artificial respiration may be needed. Refer for medical attention.[3]
Storage
- Fireproof. Separated from food and feedstuffs and incompatible materials. See Chemical Dangers. Dry.[3]
- Ambient storage temperature, venting should be pressure-vacuum type.[6]
- Protect from physical damage. Store in cool, dry, well-ventilated location away from any area where fire hazard may be acute. Outside or detached storage is preferred. Separate from oxidizing materials.[6]
- Keep containers sealed. Remove any sources of ignition.[6]
Incompatibilities
- Contact with aluminum chloride, boron trifluoride, or sulfuric acid may cause a violent exothermic polymerization. Contact with aluminum, magnesium, zinc (or galvanized metals) may produce similar results.[6]
- It has been found that allyl chloride...will react with benzene or toluene, even at -70 °C, in presence of ethyl aluminum dichloride or ethyl aluminum sesquichloride. Explosions have been reported.[6]
- Incompatible with nitric acid, ethyleneimine, ethylenediamine, chlorosulfonic acid, oleum, sodium hydroxide,[6]
- Strong oxidizers, acids, amines, iron and aluminum chlorides, magnesium, zinc.[6]
