TYPES OF HAZARD / EXPOSURE | ACUTE HAZARDS / SYMPTOMS | PREVENTION | FIRST AID / FIRE FIGHTING |
FIRE | Combustible.
Gives off irritating or toxic fumes (or gases) in a fire. |
NO open
flames. |
Powder,
alcohol-resistant foam, water spray, carbon dioxide. |
EXPLOSION | In case of
fire: keep drums, etc., cool by spraying with water.
|
EXPOSURE | AVOID ALL
CONTACT! |
IN ALL
CASES CONSULT A DOCTOR! | |
Inhalation | Burning
sensation. Cough. Sore throat. Laboured breathing. Vomiting. Convulsions.
Unconsciousness. Symptoms may be delayed (see Notes). |
Ventilation,
local exhaust, or breathing protection. |
Fresh air,
rest. Half-upright position. Artificial respiration may be needed. Refer
for medical attention. |
Skin | MAY BE
ABSORBED! Redness. Pain. Skin burns. |
Protective
gloves. Protective clothing. |
Remove
contaminated clothes. Rinse skin with plenty of water or shower. Refer for
medical attention. |
Eyes | Redness.
Pain. Severe deep burns. |
Face shield,
or eye protection in combination with breathing protection if powder.
|
First rinse
with plenty of water for several minutes (remove contact lenses if easily
possible), then take to a doctor. |
Ingestion | Abdominal
pain. Burning sensation. Shock or collapse. Convulsions. Unconsciousness.
|
Do not eat,
drink, or smoke during work. |
Rinse mouth.
Do NOT induce vomiting. Give plenty of water to drink. Refer for medical
attention. |

IMPORTANT DATA | |||
PHYSICAL
STATE; APPEARANCE: COLOURLESS, HYGROSCOPIC CRYSTALS , WITH PUNGENT ODOUR. CHEMICAL DANGERS: The substance decomposes on burning producing toxic fumes including hydrogen chloride, phosgene. The solution in water is a medium strong acid. Attacks metal. OCCUPATIONAL EXPOSURE LIMITS: TLV not established. MAK: IIb. See Notes. |
ROUTES OF
EXPOSURE: The substance can be absorbed into the body by inhalation and through the skin 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 is corrosive to the eyes, the skin and the respiratory tract. Inhalation of aerosol may cause lung oedema (see Notes). The substance may cause effects on the cardiovascular system and central nervous system, resulting in cardiac disorders, convulsions and kidney impairment. Exposure at high levels may result in death. The effects may be delayed. Medical observation is indicated. | ||
PHYSICAL PROPERTIES | |||
Boiling
point: 189°C Melting point: see Notes Density: 1.58 Solubility in water: very good Vapour pressure, Pa at 25°C: 8.68 Relative vapour density (air = 1): 3.26 |
Flash point:
126°C c.c. Auto-ignition temperature: 470°C Explosive limits, vol% in air: 8 -? Octanol/water partition coefficient as log Pow: 0.34 | ||
ENVIRONMENTAL DATA | |||
The substance is harmful to aquatic organisms. | |||
NOTES | |||
Melting point of alpha form = 63°C, beta form = 56.2°C, gamma form
= 52.5°C. The symptoms of lung oedema often do not become manifest until a
few hours have passed and they are aggravated by physical effort. Rest and
medical observation are therefore essential. Immediate administration of
an appropriate spray, by a doctor or a person authorized by him/her,
should be considered. Other UN numbers: 1750 Chloroacetic acid, solution;
3250 Chloroacetic acid, molten. MAK value is not established but full
documentation is available (MAK IIb). | |||
