| 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.
|
Powder, AFFF, foam,
carbon dioxide. |
| EXPLOSION | Above 74°C explosive
vapour/air mixtures may be formed. |
Above 74°C use a closed
system, ventilation. |
In case of fire: cool
drums, etc., by spraying with water but avoid contact of the substance
with water. Combat fire from a sheltered position. |
 | |||
| EXPOSURE | AVOID ALL CONTACT!
|
IN ALL CASES CONSULT
A DOCTOR! | |
| Inhalation | Convulsions. Cough.
Dizziness. Headache. Laboured breathing. Nausea. Shortness of breath.
Unconsciousness. Vomiting. Irregular heartbeat, tightness in the chest.
|
Closed system and
ventilation. |
Fresh air, rest.
Half-upright position. Artificial respiration if indicated. Refer for
medical attention. |
| Skin | MAY BE ABSORBED!
Redness. Pain (See Inhalation). |
Protective gloves.
Protective clothing. |
Rinse and then wash
skin with water and soap. Refer for medical attention. |
| Eyes | Redness. Pain.
|
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 cramps.
Burning sensation. Convulsions. Unconsciousness. See Notes (see
Inhalation). |
Do not eat, drink, or
smoke during work. |
Rinse mouth. Refer for
medical attention. |
| SPILLAGE DISPOSAL | PACKAGING & LABELLING |
| Sweep spilled substance
into containers. Carefully collect remainder, then remove to safe place.
Do NOT let this chemical enter the environment (extra personal protection:
complete protective clothing including self-contained breathing
apparatus). |

|
| IMPORTANT DATA | |
| PHYSICAL STATE;
APPEARANCE: COLOURLESS LIQUID , WITH CHARACTERISTIC ODOUR. PHYSICAL DANGERS: The vapour is heavier than air. CHEMICAL DANGERS: The substance decomposes rapidly on heating or on contact with bases or water, producing highly toxic and flammable hydrogen cyanide (see ICSC # 0492), and acetone (see ICSC # 0087). Reacts violently with acids and oxidants causing fire and explosion hazard. OCCUPATIONAL EXPOSURE LIMITS: TLV: 4.7 ppm; 5 mg/m 3 (ceiling values) as CN (skin) (ACGIH 1997). |
ROUTES OF EXPOSURE:
The substance can be absorbed into the body by inhalation, 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 irritates the eyes, the skin and the respiratory tract. The substance may cause effects on the cardiovascular system and central nervous system , resulting in asphyxia, cardiac disorders, convulsions, cyanosis and respiratory failure. Exposure may result in death. Medical observation is indicated. See Notes. EFFECTS OF LONG-TERM OR REPEATED EXPOSURE: The substance may have effects on the central nervous system and thyroid , resulting in impaired functions. |
| PHYSICAL PROPERTIES | |
| Boiling point: 95°C
Melting point: -19°C Relative density (water = 1): 0.93 Solubility in water: freely soluble, but decomposes in water Vapour pressure, kPa at 20°C: 3.0 Relative vapour density (air = 1): 2.93 |
Flash point: 74°C c.c.
Explosive limits, vol% in air: 2.2-12 |
| ENVIRONMENTAL DATA | |
| The
substance is very toxic to aquatic organisms. Avoid release to the
environment in circumstances different to normal use.
|
| NOTES | |
| Specific
treatment is necessary in case of poisoning with this substance; the
appropriate means with instructions must be available. Hazard and toxicity
of this substance is due to its major metabolite - hydrogen cyanide (see
ISCS # 0492). |
