TYPES OF HAZARD/ EXPOSURE

ACUTE HAZARDS/ SYMPTOMS

PREVENTION

FIRST AID/
FIRE FIGHTING

FIRE Flammable. Gives off irritating or toxic fumes (or gases) in a fire.
NO open flames, NO sparks, and NO smoking.
Powder, water spray, foam, carbon dioxide.
EXPLOSION Above 31°C explosive vapour/air mixtures may be formed.
Above 31°C use a closed system, ventilation, and explosion-proof electrical equipment.
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. Headache. Laboured breathing. Nausea. Shortness of breath. Vomiting. Tremor. 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. Serious skin burns. Burning sensation. Pain. Blisters.
Protective gloves. Protective clothing.
Remove contaminated clothes. Rinse skin with plenty of water or shower. Refer for medical attention.
•EYES Pain. Redness. Permanent loss of vision. Severe deep burns.
Face shield, or eye protection in combination with breathing protection.
First rinse with plenty of water for several minutes (remove contact lenses if easily possible), then take to a doctor.
•INGESTION Abdominal cramps. Burning sensation in the throat and chest. Diarrhoea. Headache. Nausea. Sore throat. Vomiting. Shock or collapse.
Do not eat, drink, or smoke during work. Wash hands before eating.
Rinse mouth. Do NOT induce vomiting. Give plenty of water to drink. Rest. Refer for medical attention.

PHYSICAL STATE; APPEARANCE:
COLOURLESS LIQUID , WITH CHARACTERISTIC ODOUR.

PHYSICAL DANGERS:


CHEMICAL DANGERS:
The substance will polymerize due to heating or under the influence of strong acid(s) , base(s) . On combustion, forms toxic and corrosive fumes,hydrogen chloride (see ICSC0163)andchlorine fumes (see ICSC0126). Reacts violently with strong oxidants. Reacts violently with aluminium , zinc , alcohols , phenols, amines (especially aniline), and organic acids causing fire and explosion hazard. Attacks steel in the presence of water.

OCCUPATIONAL EXPOSURE LIMITS:
TLV: 0.5 ppm as TWA; (skin); A3; (ACGIH 2003).
MAK: H; Sh;
Carcinogen category: 2; Germ cell mutagen group: 3B;
(DFG 2003).
OSHA PEL†: TWA 5 ppm (19 mg/m3) skin
NIOSH REL: Ca See Appendix A
NIOSH IDLH: Ca 75 ppm See: 106898


ROUTES OF EXPOSURE:
The substance can be absorbed into the body by inhalation, through the skin and by ingestion.

INHALATION RISK:
A harmful contamination of the air can be reached very quickly 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. Corrosive on ingestion. Inhalation of the vapour may cause lung oedema (see Notes). Inhalation of the vapour may cause asthma-like reactions. The substance may cause effects on the central nervous system , kidneys and liver , resulting in convulsions , kidney impairment , liver impairment . Exposure at high levels may result in death. The effects may be delayed. Medical observation is indicated.

EFFECTS OF LONG-TERM OR REPEATED EXPOSURE:
Repeated or prolonged contact may cause skin sensitization. The substance may have effects on the kidneys , liver and lungs , resulting in impaired functions . This substance is probably carcinogenic to humans. Animal tests show that this substance possibly causes toxicity to human reproduction or development.

PHYSICAL

Relative density of the vapour/air-mixture at 20°C (air = 1): 1.05
Flash point: 31°C c.c.
Auto-ignition temperature: 385°C
Explosive limits, vol% in air: 3.8-21
Octanol/water partition coefficient as log Pow: 0.26

ENVIRONMENTAL
DATA

The substance is harmful to aquatic organisms.

N O T E S

Other melting points: -25.6 °C and -57°C. Depending on the degree of exposure, periodic medical examination is indicated. 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. The odour warning when the exposure limit value is exceeded is insufficient. Do NOT take working clothes home.
