SYMPTOMS: Symptoms of exposure to this compound include general anesthesia, cardiac arrythmias and blood pressure depression. Other symptoms include hemorrhagic gastritis, enteritis, central nervous system depression, coma, severe respiratory depression, ventricular tachycardia and cardiac arrest. Dermatitis, swelling of the lids, hyperemia, edema of the conjuctiva and a sensation of irritation and tearing may also occur. Exposure may result in gastric irritation, rapid circulatory collapse, kidney and liver damage, heart damage, psychosis and leukopenia. Flatulence, abdominal distension, nausea, headache, giddiness, rashes and blood dyscrasias can occur. ACUTE/CHRONIC HAZARDS: This compound is an irritant of the skin and eyes. When heated to decomposition it emits toxic fumes of chlorine. (NTP, 1992)
Maintain an open airway and assist ventilation if necessary. Administer supplemental oxygen. Treat coma, hypothermia, hypotension, and pulmonary edema if they occur. Monitor patients for at least 6 hours after ingestion, because delayed absorption may occur. Patients with chloral hydrate ingestion should be monitored 18 to 24 hours because of the risk of cardiac arrhythmias. Tachyarrhythmias caused by myocardial sensitization may be treated with propranolol or esmolol. ... Administer activated charcoal orally if conditions are appropriate. Gastric lavage is not necessary after small to moderate ingestions if activated charcoal can be given promptly. ... Sedative-Hypnotic Agents
Fires involving this material can be controlled with a dry chemical, carbon dioxide or Halon extinguisher. (NTP, 1992)
Flash point data for this chemical are not available; however, it is probably combustible. (NTP, 1992)
In case of fire in the surroundings, use appropriate extinguishing media. In case of fire: keep drums, etc., cool by spraying with water.
Personal protection: particulate filter respirator adapted to the airborne concentration of the substance. Sweep spilled substance into covered containers. If appropriate, moisten first to prevent dusting. Carefully collect remainder. Then store and dispose of according to local regulations.

Collect and arrange disposal. Keep the chemical in suitable and closed containers for disposal. Remove all sources of ignition. Use spark-proof tools and explosion-proof equipment. Adhered or collected material should be promptly disposed of, in accordance with appropriate laws and regulations.
Handling in a well ventilated place. Wear suitable protective clothing. Avoid contact with skin and eyes. Avoid formation of dust and aerosols. Use non-sparking tools. Prevent fire caused by electrostatic discharge steam.
Separated from strong bases and food and feedstuffs.Chloral hydrate oral solution should be stored in tight, light-resistant containers. Chloral hydrate capsules should be stored at 15-30 deg C.

Decomposes on heating. This produces toxic and corrosive fumes including hydrogen chloride. Reacts with strong bases. This produces chloroform.
Slowly volatilizes on exposure to air.
Combustible when exposed to heat or flame.CHLORAL HYDRATE is incompatible with alkalis, alkaline earth metals, alkali carbonates and soluble barbiturates. It is decomposed by sodium hydroxide. It reduces ammoniacal silver nitrate. It liquefies when triturated with an equal quantity of menthol, camphor or thymol. (NTP, 1992). Reaction of chloral hydrate with hydroxylamine produces toxic hydrogen cyanide gas, Org. Synth., 1941, Vol. 1, 377.

WEIGHT-OF-EVIDENCE CHARACTERIZATION: Under the 1986 cancer guidelines (EPA), chloral hydrate is assigned to Group C, possible human carcinogen. Under the 1996 proposed guidelines (EPA) for carcinogen risk assessment, chloral hydrate shows suggestive evidence of human carcinogenicity by the oral route of exposure. There are no carcinogenicity data from humans. Two bioassays in rats in which chloral hydrate was administered by drinking water show no increase in tumors at any site. Because only minimal toxicity was observed in the livers of the rats in these bioassays, the tests were not conducted at the maximum tolerated dose. A chronic bioassay in female mice showed a slight increase in the severity grade of hyperplasia and a slight increase in the incidence of adenoma in the pituatary gland pars distalis at the highest exposure tested. There is some evidence that chloral hydrate causes hepatocellular tumors in male mice. An earlier study showing an increase of hepatocellular adenomas or trabecular carcinomas following a single bolus exposure could not be confirmed in a study using more animals and higher exposures. Three separate 2-year bioassays in male mice show an increased incidence of hepatocellular adenoma or carcinoma. There are no data identifying a lesion that is a precursor to the hepatocellular tumors. The strain of mice used has a very high spontaneous incidence of hepatocellular tumors. Two of the matabolites of chloral hydrate, trichloroacetic acid and dichloroacetic acid, have been shown to cause hepatocellular tumors in rodents. Trichloroacetic acid causes hepatocellular tumors only in mice. Dichloroacetic acid causes hepatocellular tumors in both rats and mice. There is an extensive database on genetic toxicity. A variety of results show that chloral hydrate is a weak gene mutagen and clastogen. Chloral hydrate induces aneuploidy in a wide variety of cell types. These latter effects are thought to arise by disruption of the spindle apparatus. A high concentration of chloral hydrate is required to cause observable effects. Although these data suggest that genotoxicity may play a role in the toxicity of chloral hydrate, the data indicate that these effects require concentrations that are unlikely to occur under physiological conditions at the exposures typically encountered from the environment. Collectively, these data provide suggestive evidence of carcinogenicity, but the weight of evidence is not sufficient to conduct a risk assessment assuming a linear response at low exposure. HUMAN CARCINOGENICITY DATA: None. ANIMAL CARCINOGENICITY DATA: Limited.

The substance is irritating to the eyes, skin and respiratory tract. The substance may cause effects on the central nervous system. This may result in disorientation, lowering of blood pressure and lowering of consciousness. Exposure at high levels could cause cardiac dysrhythmia and unconsciousness or death.
The substance may have effects on the liver. This may result in addiction, behavioural effects and liver impairment. This substance is probably carcinogenic to humans. May cause heritable genetic damage to human germ cells.
A harmful contamination of the air will be reached rather slowly on evaporation of this substance at 20°C.
AEROBIC: Biodegradation data for chloral hydrate were not available(1).
An estimated BCF of 3 was calculated in fish for chloral hydrate(SRC), using a log Kow of 0.99(1) and a regression-derived equation(2). According to a classification scheme(3), this BCF suggests the potential for bioconcentration in aquatic organisms is low(SRC).
The Koc of chloral hydrate is estimated as 82(SRC), using a log Kow of 0.99(1) and a regression-derived equation(2). According to a classification scheme(3), this estimated Koc value suggests that chloral hydrate is expected to have high mobility in soil.

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.
