Basic treatment: Establish a patent airway. Suction if necessary. Watch for signs of respiratory insufficiency and assist respirations if necessary. Administer oxygen by nonrebreather mask at 10 to 15 L/min. Monitor for pulmonary edema and treat if necessary . Monitor for shock and treat if necessary . For eye contamination, flush eyes immediately with water. Irrigate each eye continuously with normal saline during transport . Do not use emetics. For ingestion, rinse mouth and administer 5 ml/kg up to 200 ml of water for dilution if the patient can swallow, has a strong gag reflex, and does not drool. Activated charcoal is not effective . Do not attempt to neutralize because of exothermic reaction. Cover skin burns with dry, sterile dressings after decontamination . Organic acids and related compounds

SECTION 10: Stability and reactivity
Reactivity
Decomposes on heating and on burning. This produces toxic and corrosive fumes including hydrogen chloride (see ICSC 0163) and phosgene (see ICSC 0007). Reacts violently with water, alcohols, acids, bases, certain powdered metals and many other compounds. This generates fire and explosion hazard. Attacks many metals in the presence of water. Products of hydrolysis in water include corrosive hydrochloric acid and acetic acid.
Chemical stability
Readily hydrolyzes to form hydrogen chloride & acetic acid
Possibility of hazardous reactions
DANGEROUS, WHEN EXPOSED TO HEAT OR FLAME. ...The vapour is heavier than air and may travel along the ground; distant ignition possible.ACETYL CHLORIDE reacts violently with water, steam, methanol or ethanol to form hydrogen chloride and acetic acid. Reacts vigorously with bases, both organic and inorganic. Incompatible with oxidizing agents and alcohols. Produces highly toxic fumes of phosgene gas and chlorine when heated to decomposition [Sax, 9th ed., 1996, p. 35]. Reaction in a confined space with even a small amount of water may cause a violent eruption of gases [Bretherick, 5th ed., 1995, p. 281]. Vapor forms an explosive mixture with air [Kirk-Othmer, 3rd ed., Vol. 1, 1978, p. 162]. Polymerization reaction with dimethyl sulfoxide is particularly violent [Buckley, A., J. Chem. Ed., 1965, 42, p. 674]. May react vigorously or explosively if mixed with diisopropyl ether or other ethers in the presence of trace amounts of metal salts [J. Haz. Mat., 1981, 4, 291].
Conditions to avoid
no data available
Incompatible materials
Water reactive. Violent exothermic decomposition with water produces corrosive hydrochloric and acetic acids. Reacts violently with alcohols, alkalies, amines, and strong oxidizing materials.
Hazardous decomposition products
May decompose during preparation. ... when heated to decomposition, emits highly toxic fumes of phosgene and hydrogen chloride (cl-).

STOT-single exposure
The substance is corrosive to the eyes and skin. The vapour is severely irritating to the eyes and respiratory tract. Corrosive on ingestion. Exposure at high concentrations could cause asphyxiation due to swelling in the throat. Inhalation of high concentrations may cause lung oedema, but only after initial corrosive effects on the eyes and the upper respiratory tract have become manifest. The effects may be delayed. See Notes. Medical observation is indicated.
STOT-repeated exposure
Repeated or chronic inhalation of the vapour may cause chronic inflammation of the upper respiratory tract. Repeated or prolonged inhalation of high concentrations may cause effects on the lungs.
Aspiration hazard
No indication can be given about the rate at which a harmful concentration of this substance in the air is reached.
SECTION 12: Ecological information
Toxicity
- Toxicity to fish: LC50 - Pimephales promelas - 42 mg/L - 96 h.
- Toxicity to daphnia and other aquatic invertebrates: EC50 - Daphnia magna - 65 mg/L - 48 h.
- Toxicity to algae: EC50 - Navicula seminulum - 73.4 mg/L - 96 h.
- Toxicity to microorganisms: no data available
Persistence and degradability
no data available
Bioaccumulative potential
Acetyl chloride will decompose violently in water(1) forming acetic acid and hydrochloric acid(2). Because of its short half-life in water, bioconcentration of acetyl chloride in aquatic organisms is very unlikely(SRC).
Mobility in soil
Using a structure estimation method based on molecular connectivity indices(1), the Koc for acetyl chloride can be estimated to be 2(SRC). According to a classification scheme(2), this estimated Koc value suggests that acetyl chloride is expected to have very high mobility in soil. However, in view of its violent decomposition in the presence of water(3) and the high reactivity of this compound towards molecules with active hydrogen groups such as natural products containing amine, phenol, and alcohol functional groups that occur in soil(4), it is unlikely that acetyl chloride would persist for long in moist soils(SRC).
Other adverse effects
no data available
SECTION 13: Disposal considerations
Disposal methods
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.
Containers can be triply rinsed (or equivalent) and offered for recycling or reconditioning. Alternatively, the packaging can be punctured to make it unusable for other purposes and then be disposed of in a sanitary landfill. Controlled incineration with flue gas scrubbing is possible for combustible packaging materials.
