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.
NO contact with base(s),
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
AVOID ALL CONTACT!
IN ALL CASES CONSULT A DOCTOR!
•INHALATION Cough. Sore throat. Burning sensation. Laboured breathing.
Ventilation, local exhaust, or breathing protection.
Fresh air, rest. Half-upright position. Refer immediately for medical attention.
•SKIN Redness. Pain. Serious skin burns.
Protective gloves. Protective clothing.
Remove contaminated clothes. Rinse skin with plenty of water or shower. Refer immediately for medical attention.
•EYES Redness. Pain. Severe deep burns.
Face shield or eye protection in combination with breathing protection.
First rinse with plenty of water (remove contact lenses if easily possible). Refer immediately for medical attention.
•INGESTION 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, COLOURLESS LIQUID , WITH PUNGENT ODOUR.

PHYSICAL DANGERS:
The vapour is heavier than air.

CHEMICAL DANGERS:
The substance decomposes on contact with hot surfaces or flames producing toxic fumes . The substance is a medium strong acid. Reacts violently with strong bases , reducing agents and oxidants producing toxic and corrosive fumes including hydrogen fluoride . Attacks many metals forming flammable/explosive gas (hydrogen - see ICSC 0001). Attacks some forms of rubber.

OCCUPATIONAL EXPOSURE LIMITS:
TLV not established.
MAK not established.


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

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 fumes may cause lung oedema (see Notes).

EFFECTS OF LONG-TERM OR REPEATED EXPOSURE:

PHYSICAL
PROPERTIES

Boiling point: 72°C
Melting point: -15°C
Relative density (water = 1): 1.5
Solubility in water, g/100 ml at 20°C: 100
(very good)
Vapour pressure, kPa at 20°C: 11
Relative vapour density (air = 1): 3.9
Relative density of the vapour/air-mixture at 20°C (air = 1): 1.3
Octanol/water partition coefficient as log Pow: -2.1

ENVIRONMENTAL
DATA

The substance is harmful to aquatic organisms.

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 is therefore essential.
