TYPES OF HAZARD/ EXPOSURE

ACUTE HAZARDS/ SYMPTOMS

PREVENTION

FIRST AID/
FIRE FIGHTING

FIRE Highly flammable. Gives off irritating or toxic fumes (or gases) in a fire.
NO open flames, NO sparks, and NO smoking.
Powder, alcohol-resistant foam, water in large amounts, carbon dioxide.
EXPLOSION Vapour/air mixtures are explosive.
Closed system, ventilation, explosion-proof electrical equipment and lighting.
In case of fire: keep drums, etc., cool by spraying with water.
EXPOSURE
AVOID ALL CONTACT!
IN ALL CASES CONSULT A DOCTOR!
 •INHALATION Sore throat. Cough. Burning sensation. Headache. Flushing of the face. Vomiting. Dizziness. Shortness of breath. Laboured breathing. 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! Pain. Redness. Blisters. Skin burns.
Protective gloves. Protective clothing.
Remove contaminated clothes. Rinse skin with plenty of water or shower. Refer for medical attention.
 •EYES Pain. Redness. Severe deep burns. Loss of vision.
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 Burning sensation. Abdominal pain. Diarrhoea. Nausea. Vomiting. Shock or collapse.
Do not eat, drink, or smoke during work.
Rinse mouth. Do NOT induce vomiting. Refer for medical attention.

PHYSICAL STATE; APPEARANCE:
COLOURLESS LIQUID , WITH CHARACTERISTIC ODOUR. TURNS TO YELLOW ON STANDING.

PHYSICAL DANGERS:
The vapour is heavier than air and may travel along the ground; distant ignition possible.

CHEMICAL DANGERS:
The substance decomposes on heating or on burning producing toxic fumes including nitrogen oxides . The substance is a weak base. Reacts with strong oxidants and acids causing fire and explosion hazard. Attacks some metals in presence of water.

OCCUPATIONAL EXPOSURE LIMITS:
TLV: 5 ppm (Ceiling value); (skin); (ACGIH 200).
MAK: 2 ppm; 6.1 mg/m3;
Peak limitation category: I(2); Pregnancy risk group: C;
(DFG 2006).
OSHA PEL: C 5 ppm (15 mg/m3) skin
NIOSH REL: C 5 ppm (15 mg/m3) skin
NIOSH IDLH: 300 ppm See: 109739


ROUTES OF EXPOSURE:
The substance can be absorbed into the body by inhalation of its vapour, 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 and the vapour is corrosive to the eyes, the skin and the respiratory tract. Inhalation of the vapour may cause lung oedema (see Notes). The effects may be delayed. Medical observation is indicated.

EFFECTS OF LONG-TERM OR REPEATED EXPOSURE:
Repeated or prolonged contact with skin may cause dermatitis.

PHYSICAL
PROPERTIES

Boiling point: 78°C
Melting point: -50°C
Relative density (water = 1): 0.74
Solubility in water:
miscible
Vapour pressure, kPa at 20°C: 10.9
Relative vapour density (air = 1): 2.5
Flash point: -12°C c.c.
Auto-ignition temperature: 312°C
Explosive limits, vol% in air: 1.7-9.8
Octanol/water partition coefficient as log Pow: 0.86

ENVIRONMENTAL
DATA

The substance is harmful to aquatic organisms.

N O T E S

The occupational exposure limit value should not be exceeded during any part of the working exposure. 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 is therefore essential. Immediate administration of an appropriate inhalation therapy by a doctor or a person authorized by him/her, should be considered. Card has been partly updated in October 2005. See sections Occupational Exposure Limits, Emergency Response. Card has been partly updated in October 2006. See sections Occupational Exposure Limits.
