TYPES OF HAZARD / EXPOSURE ACUTE HAZARDS / SYMPTOMS PREVENTION FIRST AID / FIRE FIGHTING
FIRE Not combustible. Gives off irritating or toxic fumes (or gases) in a fire.

In case of fire in the surroundings: use appropriate extinguishing media.
EXPLOSION

In case of fire: keep drums, etc., cool by spraying with water.
EXPOSURE
PREVENT DISPERSION OF DUST!

Inhalation Confusion. Drowsiness. Nausea. Unconsciousness.

Fresh air, rest. Artificial respiration may be needed. Refer for medical attention.
Skin Redness.
Protective gloves.
Rinse skin with plenty of water or shower.

CHLORAL HYDRATE ICSC: 0234
IMPORTANT DATA
PHYSICAL STATE; APPEARANCE:
TRANSPARENT COLOURLESS CRYSTALS, WITH CHARACTERISTIC ODOUR.

CHEMICAL DANGERS:
The substance decomposes on heating producing toxic and corrosive fumes including hydrogen chloride. Reacts with strong bases producing chloroform.

OCCUPATIONAL EXPOSURE LIMITS:
TLV not established.
ROUTES OF EXPOSURE:
The substance can be absorbed into the body by inhalation of its aerosol and by ingestion.

INHALATION RISK:
A harmful contamination of the air will be reached rather slowly on evaporation of this substance at 20C.

EFFECTS OF SHORT-TERM EXPOSURE:
The substance is irritating to the eyes, the skin and the respiratory tract. The substance may cause effects on the central nervous system, cardiovascular system, liver and kidneys, resulting in lowering of consciousness, cardiac disorders and impaired functions. Exposure at high levels may result in unconsciousness.

PHYSICAL PROPERTIES
Boiling point (decomposes): 97C
Melting point: 57-60C
Density: 1.9 g/cm
Solubility in water: very good
Octanol/water partition coefficient as log Pow: 0.99
ENVIRONMENTAL DATA
This substance may be hazardous to the environment; special attention should be given to water organisms.
NOTES
Use of alcoholic beverages enhances the harmful effect. Card has been partly updated in October 2005. See section Emergency Response.
