TYPES OF HAZARD/ EXPOSURE

ACUTE HAZARDS/ SYMPTOMS

PREVENTION

FIRST AID/
FIRE FIGHTING

FIRE Not combustible but enhances combustion of other substances. Many reactions may cause fire or explosion. Heating will cause rise in pressure with risk of bursting. Gives off irritating or toxic fumes (or gases) in a fire.
NO contact with incompatible materials; see Chemical Dangers.
In case of fire in the surroundings: use appropriate extinguishing media.
EXPLOSION Risk of fire and explosion (See Chemical Dangers).
NO contact with incompatible materials; see Chemical Dangers.
In case of fire: keep cylinder cool by spraying with water.
EXPOSURE
AVOID ALL CONTACT!
IN ALL CASES CONSULT A DOCTOR!
•INHALATION Cough. Sore throat. Shortness of breath. Dizziness. Headache. Wheezing. Laboured breathing. Symptoms may be delayed (see Notes).
Breathing protection. Closed system and ventilation.
Fresh air, rest. Half-upright position. Artificial respiration may be needed. Refer immediately for medical attention.
•SKIN Redness. Burning sensation. Pain. Serious skin burns.
Protective gloves. Protective clothing.
First rinse with plenty of water for at least 15 minutes, then remove contaminated clothes and rinse again. Put clothes in sealable container . Refer immediately for medical attention.
•EYES Causes watering of the eyes. Redness. Blurred vision. Pain. Burns .
Safety goggles , face shield and eye protection in combination with breathing protection.
Rinse with plenty of water (remove contact lenses if easily possible). Refer immediately for medical attention.
•INGESTION Burns in mouth and throat. Burning sensation in the throat and chest. Abdominal pain. Shock or collapse.
Do not eat, drink, or smoke during work.
Rinse mouth. Do NOT induce vomiting. Refer immediately for medical attention.

PHYSICAL STATE; APPEARANCE:
FUMING RED TO BROWN LIQUID , WITH PUNGENT ODOUR.

PHYSICAL DANGERS:
The vapour is heavier than air.

CHEMICAL DANGERS:
Upon heating, toxic fumes are formed. The substance is a strong oxidant and reacts violently with combustible and reducing materials. The substance reacts with most organic and inorganic compounds , causing fire and explosion hazard. Attacks metal, some forms of

OCCUPATIONAL EXPOSURE LIMITS:
TLV: 0.1 ppm as TWA; 0.2 ppm as STEL; (ACGIH 2008).
EU OEL: 0.1 ppm, 0.7 mg/m3 as TWA; (EU 2006).
OSHA PEL†: TWA 0.1 ppm (0.7 mg/m3)
NIOSH REL: TWA 0.1 ppm (0.7 mg/m3) ST 0.3 ppm (2 mg/m3)
NIOSH IDLH: 3 ppm See: 7726956


ROUTES OF EXPOSURE:
Serious local effects by all routes of exposure.

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

EFFECTS OF SHORT-TERM EXPOSURE:
Lachrymation. The substance is corrosive to the eyes, the skin and the respiratory tract. Corrosive on ingestion. Inhalation may cause asthma-like reactions. Inhalation may cause pneumonitis. Inhalation may cause lung oedema, but only after initial corrosive effects on eyes and/or airways have become manifest. The effects may be delayed. Medical observation is indicated. Exposure may result in death. 6 Peer-review 2008

EFFECTS OF LONG-TERM OR REPEATED EXPOSURE:
The substance may have effects on the respiratory tract and lungs , resulting in chronic inflammations and impaired functions .

PHYSICAL
PROPERTIES

Boiling point: 58.8°C
Melting point: -7.2°C
Relative density (water = 1): 3.1
Solubility in water, g/100 ml at 20°C: 4.0
Vapour pressure, kPa at 20°C: 23.3
Relative vapour density (air = 1): 5.5
Relative density of the vapour/air-mixture at 20°C (air = 1): 2.0
Viscosity, mm2/s at 40 °C: 0.264

ENVIRONMENTAL
DATA

The substance is very toxic to aquatic organisms. It is strongly advised that this substance does not enter the environment.

N O T E S

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 inhalation therapy by a doctor or a person authorized by him/her, should be considered.
