| TYPES OF
HAZARD / EXPOSURE |
ACUTE HAZARDS / SYMPTOMS | PREVENTION | FIRST AID / FIRE FIGHTING |
| FIRE | Flammable. Gives off
irritating or toxic fumes (or gases) in a fire. |
NO open flames, NO
sparks, and NO smoking. |
Water spray, powder,
carbon dioxide. |
| EXPLOSION | Above 38°C explosive
vapour/air mixtures may be formed. Finely dispersed particles form
explosive mixtures in air. |
Prevent deposition of
dust; closed system, dust explosion-proof electrical equipment and
lighting. Prevent build-up of electrostatic charges (e.g., by grounding).
|
In case of fire: keep
drums, etc., cool by spraying with water. |

| EXPOSURE | PREVENT DISPERSION
OF DUST! STRICT HYGIENE! |
IN ALL CASES CONSULT
A DOCTOR! | |
| Inhalation | Burning sensation.
Cough. Laboured breathing. Shortness of breath. Sore throat.
|
Local exhaust or
breathing protection. |
Fresh air, rest.
Half-upright position. Refer for medical attention. |
| Skin | Redness. Pain.
Discolouration. Blisters. |
Protective gloves.
Protective clothing. |
Remove contaminated
clothes. Rinse and then wash skin with water and soap. Refer for medical
attention. |
| Eyes | Redness. Pain. Blurred
vision. Brown staining. |
Safety spectacles, 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 pain. Burning
sensation. Diarrhoea. Vomiting. |
Do not eat, drink, or
smoke during work. Wash hands before eating. |
Rinse mouth. Give a
slurry of activated charcoal in water to drink. Do NOT induce vomiting.
Refer for medical attention. |
| SPILLAGE DISPOSAL | PACKAGING & LABELLING |
| Sweep spilled substance
into containers; if appropriate, moisten first to prevent dusting.
Carefully collect remainder, then remove to safe place. Do NOT let this
chemical enter the environment. (extra personal protection: P3 filter
respirator for toxic particles). |
T Symbol R: 23/25-36/37/38 S: 1/2-26-28-45 UN Hazard Class: 6.1 UN Pack Group: II Do not transport with food and feedstuffs. |
| EMERGENCY RESPONSE | STORAGE |
| Transport Emergency
Card: TEC (R)-61G12b NFPA Code: H1; F2; R1; |
Fireproof. Separated
from combustible and reducing substances, food and feedstuffs. Cool. Dry.
|
| IMPORTANT DATA | |
| PHYSICAL STATE;
APPEARANCE: YELLOW CRYSTALS , WITH PUNGENT ODOUR. CAN SUBLIME EVEN AT ROOM TEMPERATURE. PHYSICAL DANGERS: Dust explosion possible if in powder or granular form, mixed with air. If dry, it can be charged electrostatically by swirling, pneumatic transport, pouring, etc. CHEMICAL DANGERS: The substance decomposes on warming above 60°C, when moist, producing carbon monoxide. Reacts as a weak oxidant violently with some combustible substances, reducing agents and strong bases. OCCUPATIONAL EXPOSURE LIMITS: TLV: 0.1 ppm; 0.44 mg/m 3 (as TWA) (ACGIH 1997). MAK: 0.1 ppm; 0.4 mg/m 3; (1997) |
ROUTES OF EXPOSURE:
The substance can be absorbed into the body by inhalation, 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 eyes. Exposure far above the OEL may result in respiratory failure and death. EFFECTS OF LONG-TERM OR REPEATED EXPOSURE: Repeated or prolonged contact with skin may cause dermatitis. The substance may have effects on the skin and eyes , resulting in discolouration, inflammation and injury of the corneal epithelium. |
| PHYSICAL PROPERTIES | |
| Boiling point: ca.
180°C Melting point: 116°C Solubility in water: poor Vapour pressure, Pa at 20°C: 12 Relative vapour density (air = 1): 3.7 |
Relative density of the
vapour/air-mixture at 20°C (air = 1): 1.0 Flash point: 38-93°C (see Notes) Auto-ignition temperature: 560°C Octanol/water partition coefficient as log Pow: 0.2 |
| ENVIRONMENTAL DATA | |
| The
substance is very toxic to aquatic organisms.
|
| NOTES | |
| Physical
properties (e.g. flash point) depend largely on humidity. The odour
warning when the exposure limit value is exceeded is insufficient.
