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.
Water spray, foam, powder, carbon dioxide.
EXPLOSION

In case of fire: keep drums, etc., cool by spraying with water.
EXPOSURE
STRICT HYGIENE!
IN ALL CASES CONSULT A DOCTOR!
Inhalation Confusion. Convulsions. Dizziness. Headache. Laboured breathing. Nausea. Vomiting. See Notes.
Ventilation, local exhaust, or breathing protection.
Fresh air, rest. Artificial respiration may be needed. Refer for medical attention. See Notes.
Skin MAY BE ABSORBED! Redness. Pain.
Protective gloves. Protective clothing.
Remove contaminated clothes. Rinse and then wash skin with water and soap. Refer for medical attention.
Eyes Redness. Blurred vision. Severe deep burns.
Face shield.
First rinse with plenty of water for several minutes (remove contact lenses if easily possible), then take to a doctor.
Ingestion Abdominal pain. (Further see Inhalation).
Do not eat, drink, or smoke during work. Wash hands before eating.
Rinse mouth. Induce vomiting (ONLY IN CONSCIOUS PERSONS!). Give plenty of water to drink. Refer for medical attention. See Notes.

IMPORTANT DATA
PHYSICAL STATE; APPEARANCE:
ODOURLESS OILY COLOURLESS LIQUID.

CHEMICAL DANGERS:
The substance decomposes on heating or on burning producing highly toxic hydrogen cyanide (see ICSC 0492). Reacts violently with strong oxidants.

OCCUPATIONAL EXPOSURE LIMITS:
TLV: 2 ppm as TWA; (skin); (ACGIH 2004).
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 not or will only very slowly be reached on evaporation of this substance at 20C.

EFFECTS OF SHORT-TERM EXPOSURE:
The substance irritates the eyes and the skin. Exposure could cause convulsions. Exposure may result in unconsciousness. Exposure may result in death. Medical observation is indicated.

EFFECTS OF LONG-TERM OR REPEATED EXPOSURE:
The substance may have effects on the blood and adrenals, resulting in anaemia and tissue lesions.
PHYSICAL PROPERTIES

Relative vapour density (air = 1): 3.7
Flash point: 159C c.c. (see Notes)
Auto-ignition temperature: 550C
Explosive limits, vol% in air: 1.7-4.9
Octanol/water partition coefficient as log Pow: -0.32
ENVIRONMENTAL DATA

NOTES
Upon poisoning by adiponitrile, specific first aid and treatment are essential. Consult a doctor. The flash point of adiponitrile, technical grade is 93C (o.c.). Do NOT take working clothes home.
