PREVENTION

FIRST AID/
FIRE FIGHTING

FIRE Combustible. Gives off irritating or toxic fumes (or gases) in a fire.
NO open flames.
Water spray, carbon dioxide, foam, powder .
EXPLOSION Above 91°C explosive vapour/air mixtures may be formed.
Above 91°C use a closed system, ventilation.

EXPOSURE
AVOID ALL CONTACT!

•INHALATION Dizziness. Drowsiness. Headache. Nausea.
Ventilation, local exhaust, or breathing protection.
Fresh air, rest. Refer for medical attention.
•SKIN MAY BE ABSORBED! (See Ingestion)
Protective gloves. Protective clothing.
Remove contaminated clothes. Rinse and then wash skin with water and soap. Refer for medical attention.
•EYES
Safety spectacles or eye protection in combination with breathing protection.
Rinse with plenty of water (remove contact lenses if easily possible).
•INGESTION Blue lips or fingernails. Blue skin. Dizziness. Drowsiness. Headache. Nausea. Unconsciousness.
Do not eat, drink, or smoke during work.
Rinse mouth. Refer for medical attention.

PHYSICAL STATE; APPEARANCE:
YELLOW LIQUID , WITH CHARACTERISTIC ODOUR. TURNS BROWN ON EXPOSURE TO AIR.

PHYSICAL DANGERS:
The vapour is heavier than air.

CHEMICAL DANGERS:
The substance decomposes on burning producing toxic and corrosive fumes including nitrogen oxides . Reacts violently with strong oxidants. Reacts with hypochlorites forming explosive chloroamines. Reacts with acids , acid anhydrides , acid chlorides and halogens . Attacks plastic and rubber.

OCCUPATIONAL EXPOSURE LIMITS:
TLV not established.
See Notes.
MAK: skin absorption (H);
Carcinogen category: 2;
(DFG 2006).


ROUTES OF EXPOSURE:
The substance can be absorbed into the body in hazardous amounts by inhalation of its aerosol, through the skin and by ingestion.

INHALATION RISK:
A harmful contamination of the air will be reached slowly on evaporation of this substance at 20°C; on spraying or dispersing, however, much faster.

EFFECTS OF SHORT-TERM EXPOSURE:
Exposure at high levels could cause lowering of consciousness. Exposure at high levels may result in the formation of methaemoglobin. The effects may be delayed. Medical observation is indicated.

EFFECTS OF LONG-TERM OR REPEATED EXPOSURE:
The substance may have effects on the blood , resulting in anaemia . The substance may have effects on the liver . This substance is possibly carcinogenic to humans.
