TYPES OF HAZARD/ EXPOSURE

ACUTE HAZARDS/ SYMPTOMS

PREVENTION

FIRST AID/
FIRE FIGHTING

FIRE Highly flammable. Gives off irritating or toxic fumes (or gases) in a fire.
NO open flames, NO sparks, and NO smoking. NO contact with strong base(s) and strong acid(s).
Powder, alcohol-resistant foam, water spray, carbon dioxide.
EXPLOSION Vapour/air mixtures are explosive. Risk of fire and explosion on contact with strong base(s) and strong acid(s).
Closed system, ventilation, explosion-proof electrical equipment and lighting. Use non-sparking handtools.
In case of fire: keep drums, etc., cool by spraying with water.
EXPOSURE
AVOID ALL CONTACT!
IN ALL CASES CONSULT A DOCTOR!
•INHALATION Dizziness. Headache. Nausea. Shortness of breath. Vomiting. Weakness. Convulsions. Chest tightness.
Closed system and ventilation.
Fresh air, rest. Refer for medical attention. See Notes.
•SKIN MAY BE ABSORBED! Redness. Pain. Blisters. (Further see Inhalation).
Protective gloves. Protective clothing.
First rinse with plenty of water, then remove contaminated clothes and rinse again. Refer for medical attention.
•EYES Redness. Pain.
Safety goggles 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. Vomiting. (Further see Inhalation).
Do not eat, drink, or smoke during work. Wash hands before eating.
Rinse mouth. Give a slurry of activated charcoal in water to drink. Induce vomiting (ONLY IN CONSCIOUS PERSONS!). Refer for medical attention.

PHYSICAL STATE; APPEARANCE:
COLOURLESS OR PALE YELLOW LIQUID , WITH PUNGENT ODOUR.

PHYSICAL DANGERS:
The vapour is heavier than air and may travel along the ground; distant ignition possible.

CHEMICAL DANGERS:
The substance polymerizes due to heating or under the influence of light and bases , causing fire and explosion hazard. The substance decomposes on heating producing toxic fumes including hydrogen cyanide , nitrogen oxides . Reacts violently with strong acids , and strong oxidants . Attacks plastics and rubber.

OCCUPATIONAL EXPOSURE LIMITS:
TLV: 2 ppm as TWA; (skin); A3 (confirmed animal carcinogen with unknown relevance to humans); (ACGIH 2004).
MAK: skin absorption (H); sensitization of skin (Sh);
Carcinogen category: 2;
(DFG 2004).
OSHA PEL: 1910.1045 TWA 2 ppm C 10 ppm 15-minute skin
NIOSH REL: Ca TWA 1 ppm C 10 ppm 15-minute skin See Appendix A
NIOSH IDLH: Ca 85 ppm See: 107131


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

EFFECTS OF SHORT-TERM EXPOSURE:
The substance and the vapour is irritating to the eyes , the skin and the respiratory tract . The substance may cause effects on the central nervous system . Exposure far above the OEL may result in death. The effects may be delayed. See Notes. Medical observation is indicated.

EFFECTS OF LONG-TERM OR REPEATED EXPOSURE:
Repeated or prolonged contact may cause skin sensitization. The substance may have effects on the central nervous system and liver . This substance is possibly carcinogenic to humans.

ENVIRONMENTAL
DATA

The substance is harmful to aquatic organisms.

N O T E S

Depending on the degree of exposure, periodic medical examination is suggested. Exposure to the substance will result in cyanide formation. Also consult ICSC of a cyanide salt, such as 0671. Specific treatment is necessary in case of poisoning with this substance; the appropriate means with instructions must be available. The odour warning when the exposure limit value is exceeded is insufficient. Rinse contaminated clothes (fire hazard) with plenty of water. Card has been partly updated in April 2005. See section Occupational Exposure Limits.
