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, alcohol-resistant foam, water spray, carbon dioxide.
EXPLOSION Above 26°C explosive vapour/air mixtures may be formed.
Above 26°C use a closed system, ventilation, and explosion-proof electrical equipment.
In case of fire: keep drums, etc., cool by spraying with water.
EXPOSURE
PREVENT GENERATION OF MISTS!

•INHALATION Cough. Dizziness. Drowsiness. Headache. Nausea. Sore throat. Unconsciousness. Weakness.
Ventilation, local exhaust, or breathing protection.
Fresh air, rest. Refer for medical attention.
•SKIN MAY BE ABSORBED! Dry skin. Redness. Burning sensation. Pain. Blisters. (Further see Inhalation).
Protective gloves. Protective clothing.
Remove contaminated clothes. Rinse skin with plenty of water or shower. Refer for medical attention.
•EYES Redness. Pain. Blurred 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 pain. Burning sensation. Diarrhoea. Vomiting. (Further see Inhalation).
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.

PHYSICAL DANGERS:


CHEMICAL DANGERS:
The substance decomposes on burning producing toxic fumes including nitrogen oxides. Reacts with oxidants. Attacks copper and its alloys.

OCCUPATIONAL EXPOSURE LIMITS:
TLV not established.


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 rather quickly on evaporation of this substance at 20°C.

EFFECTS OF SHORT-TERM EXPOSURE:
The substance is corrosive to the eyes and the skin. The vapour of the substance irritates the respiratory tract. Exposure at high level may result in unconsciousness.

EFFECTS OF LONG-TERM OR REPEATED EXPOSURE:
The liquid defats the skin.
