TYPES OF HAZARD/ EXPOSURE	ACUTE HAZARDS/ SYMPTOMS	PREVENTION	FIRST AID/ FIRE FIGHTING
FIRE	Combustible. Gives off irritating or toxic fumes (or gases) in a fire.	NO open flames. NO contact with nitric acid.	Powder, AFFF, foam, carbon dioxide.
EXPLOSION	Above 86°C explosive vapour/air mixtures may be formed.	Above 86°C use a closed system, ventilation.	In case of fire: keep drums, etc., cool by spraying with water.

EXPOSURE		STRICT HYGIENE!	IN ALL CASES CONSULT A DOCTOR!
INHALATION	Blue lips or finger nails. Blue skin. Dizziness. Headache. Laboured breathing. Shortness of breath. Weakness.	Ventilation, local exhaust, or breathing protection.	Fresh air, rest. Artificial respiration if indicated. Refer for medical attention.
SKIN	MAY BE ABSORBED! Redness. Blue lips or fingernails. Blue skin (Further see Inhalation).	Protective gloves. Protective clothing.	Remove contaminated clothes. Rinse and then wash skin with water and soap. Refer for medical attention.
EYES	Redness. Pain.	Safety goggles.	First rinse with plenty of water for several minutes (remove contact lenses if easily possible), then take to a doctor.
INGESTION	Blue lips or fingernails. Blue skin. Dizziness. Headache. Laboured breathing (further see Inhalation).	Do not eat, drink, or smoke during work.	Rinse mouth. Induce vomiting (ONLY IN CONSCIOUS PERSONS!). Refer for medical attention.

SPILLAGE DISPOSAL

STORAGE

PACKAGING & LABELLING

PHYSICAL STATE; APPEARANCE:
COLOURLESS TO YELLOW LIQUID, TURNS DARK ON EXPOSURE TO AIR AND LIGHT.

PHYSICAL DANGERS:

CHEMICAL DANGERS:
The substance decomposes on heating or on burning producing toxic fumes including nitrogen oxides. Reacts violently with oxidants, especially nitric acid.

OCCUPATIONAL EXPOSURE LIMITS (OELs):
TLV: 2 ppm; 8.8 mg/m³ (as TWA) (skin) (ACGIH 1994-1995).

ROUTES OF EXPOSURE:
The substance can be absorbed into the body by inhalation and through the skin, and by ingestion.

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

EFFECTS OF SHORT-TERM EXPOSURE:
The substance irritates the eyes and the skin. The substance may cause effects on the blood , resulting in formation of methaemoglobin. The effects may be delayed. Medical observation is indicated. See Notes.

EFFECTS OF LONG-TERM OR REPEATED EXPOSURE:
The substance may have effects on the blood , resulting in formation of methaemoglobin (see Notes).
