TYPES OF
HAZARD / EXPOSURE |
ACUTE HAZARDS / SYMPTOMS | PREVENTION | FIRST AID / FIRE FIGHTING |
| FIRE |
Combustible. Heating will cause rise in pressure with risk of bursting.
|
NO open flames.
|
Powder, AFFF, foam, carbon dioxide.
|
| EXPLOSION |
Above 76°C explosive vapour/air mixtures may be formed.
|
Above 76°C use a closed system, ventilation.
|
In case of fire: keep drums, etc., cool by spraying with water.
|

| EXPOSURE |
|
PREVENT GENERATION OF MISTS!
|
|
| Inhalation |
Cough. Sore throat.
|
Ventilation, local exhaust, or breathing protection.
|
Fresh air, rest.
|
| Skin |
Redness.
|
Protective gloves.
|
Remove contaminated clothes. Rinse skin with plenty of water or shower.
|
| Eyes |
Redness. Pain.
|
Safety spectacles.
|
First rinse with plenty of water for several minutes (remove contact lenses if easily possible), then take to a doctor.
|
| Ingestion |
|
Do not eat, drink, or smoke during work. Wash hands before eating.
|
Rinse mouth. Do NOT induce vomiting. Rest.
|
| SPILLAGE DISPOSAL | PACKAGING & LABELLING |
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 (extra personal protection: filter respirator for organic gases and vapours).
|
|
| EMERGENCY RESPONSE | STORAGE |
NFPA Code: H2; F2; R2;
|
Separated from oxidants. Cool. Store only if stabilized.
|
| IMPORTANT DATA | |
|
PHYSICAL STATE; APPEARANCE:
COLOURLESS LIQUID , WITH CHARACTERISTIC ODOUR. CHEMICAL DANGERS: The substance can polymerize due to heating with fire or explosion hazard. Reacts violently with oxidants. OCCUPATIONAL EXPOSURE LIMITS: TLV: 10 ppm; 53 mg/m 3 (ACGIH 1996). |
ROUTES OF EXPOSURE:
The substance can be absorbed into the body by inhalation of its vapour. INHALATION RISK: No indication can be given about the rate in which a harmful concentration in the air is reached on evaporation of this substance at 20°C. EFFECTS OF SHORT-TERM EXPOSURE: The substance irritates the eyes, the skin and the respiratory tract. EFFECTS OF LONG-TERM OR REPEATED EXPOSURE: Repeated or prolonged contact with skin may cause dermatitis. |

| ENVIRONMENTAL DATA | |
|
|
| NOTES | |
|
The commercial form of vinylbenzene contains the three isomeric forms but the meta isomer predominates. Insufficient data are available on the effect of this substance on human health, therefore utmost care must be taken. An added stabilizer or inhibitor can influence the toxicological properties of this substance, consult an expert. DVB-22, DVB-55 are trade names. Also consult ICSC # 0073 on Styrene.
