| TYPES OF HAZARD / EXPOSURE | ACUTE HAZARDS / SYMPTOMS | PREVENTION | FIRST AID / FIRE FIGHTING |
| FIRE |
Highly flammable.
|
NO open flames, NO sparks, and NO smoking.
|
Powder, AFFF, foam, carbon dioxide.
|
| EXPLOSION |
Vapour/air mixtures are explosive. Risk of fire and explosion: see Chemical Dangers.
|
Closed system, ventilation, explosion-proof electrical equipment and lighting. Do NOT use compressed air for filling, discharging, or handling. Use non-sparking handtools. Prevent build-up of electrostatic charges (e.g., by grounding).
|
In case of fire: keep drums, etc., cool by spraying with water.
|
| EXPOSURE |
|
AVOID ALL CONTACT!
|
|
| Inhalation |
Dizziness. Drowsiness. Headache. Nausea. Shortness of breath. Convulsions. Unconsciousness.
|
Ventilation, local exhaust, or breathing protection.
|
Fresh air, rest. Refer for medical attention.
|
| Skin |
MAY BE ABSORBED! Dry skin. Redness. Pain. (Further see Inhalation).
|
Protective gloves. Protective clothing.
|
Remove contaminated clothes. Rinse skin with plenty of water or shower. 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 pain. Sore throat. Vomiting. (Further see Inhalation).
|
Do not eat, drink, or smoke during work.
|
Rinse mouth. Do NOT induce vomiting. Refer for medical attention.
|
| SPILLAGE DISPOSAL | PACKAGING & LABELLING | |||||||
|
Remove all ignition sources. Collect leaking and spilled liquid in sealable containers as far as possible. Absorb remaining liquid in sand or inert absorbent and remove to safe place. Do NOT wash away into sewer. Do NOT let this chemical enter the environment. Personal protection: complete protective clothing including self-contained breathing apparatus.
|
Do not transport with food and feedstuffs. EU Classification Symbol: F, T R: 45-46-11-36/38-48/23/24/25-65 S: 53-45 Note: [E] UN Classification UN Hazard Class: 3 UN Pack Group: II | |||||||

Transport Emergency Card: TEC (R)-30S1114 / 30GF1-II NFPA Code: H2; F3; R0 |
Fireproof. Separated from food and feedstuffs oxidants and halogens.

| IMPORTANT DATA | |||
|
PHYSICAL STATE; APPEARANCE: COLOURLESS LIQUID, WITH CHARACTERISTIC ODOUR. PHYSICAL DANGERS: The vapour is heavier than air and may travel along the ground; distant ignition possible. As a result of flow, agitation, etc., electrostatic charges can be generated. CHEMICAL DANGERS: Reacts violently with oxidants, nitric acid, sulfuric acid and halogens causing fire and explosion hazard. Attacks plastic and rubber. OCCUPATIONAL EXPOSURE LIMITS: TLV: 0.5 ppm as TWA; 2.5 ppm as STEL; (skin); A1; BEI issued; (ACGIH 2004). MAK: H; Carcinogen category: 1; Germ cell mutagen group: 3A; (DFG 2004). |
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 very quickly on evaporation of this substance at 20°C. EFFECTS OF SHORT-TERM EXPOSURE: The substance is irritating to the eyes, the skin and the respiratory tract. Swallowing the liquid may cause aspiration into the lungs with the risk of chemical pneumonitis. The substance may cause effects on the central nervous system, resulting in lowering of consciousness. Exposure far above the occupational exposure limit value may result in unconsciousness and death. EFFECTS OF LONG-TERM OR REPEATED EXPOSURE: The liquid defats the skin. The substance may have effects on the bone marrow and immune system, resulting in a decrease of blood cells. This substance is carcinogenic to humans. | ||

| ENVIRONMENTAL DATA | |||
|
The substance is very toxic to aquatic organisms.
| |||
| NOTES | |||
|
Use of alcoholic beverages enhances the harmful effect. Depending on the degree of exposure, periodic medical examination is indicated. The odour warning when the exposure limit value is exceeded is insufficient. Card has been partly updated in October 2004.
