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.
Closed system, ventilation, explosion-proof electrical equipment and lighting. Prevent build-up of electrostatic charges (e.g., by grounding). Do NOT use compressed air for filling, discharging, or handling.
In case of fire: keep drums, etc., cool by spraying with water.
EXPOSURE
PREVENT GENERATION OF MISTS!

Inhalation Ataxia. Dizziness. Drowsiness. Headache. Unconsciousness.
Ventilation, local exhaust, or breathing protection.
Fresh air, rest. Refer for medical attention.
Skin
Protective gloves.
Remove contaminated clothes. Rinse and then wash skin with water and soap.
Eyes
Safety spectacles 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



SPILLAGE DISPOSAL PACKAGING & LABELLING
Collect leaking liquid in sealable containers. Absorb remaining liquid in sand or inert absorbent and remove to safe place. Do NOT wash away into sewer (extra personal protection: self-contained breathing apparatus).
UN Hazard Class: 3
UN Pack Group: I


EMERGENCY RESPONSE STORAGE
Transport Emergency Card: TEC (R)-685 NFPA Code: H2; F4; R2;
Fireproof. Separated from strong oxidants, acids. Cool. Keep under inert gas. Store only if stabilized.

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:
The substance can form explosive peroxides. The substance, as a liquid or vapour, can readily polymerize. Reacts violently with oxidants and acids causing fire and explosion hazard.

OCCUPATIONAL EXPOSURE LIMITS:
TLV not established.
ROUTES OF EXPOSURE:
The substance can be absorbed into the body by inhalation of its vapour.

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 may cause effects on the central nervous system , resulting in unconsciousness.


PHYSICAL PROPERTIES
Boiling point: 36°C
Melting point: -115°C
Relative density (water = 1): 0.8
Solubility in water: none
Vapour pressure, kPa at 20°C: 57
Relative vapour density (air = 1): 2.5
Flash point: <-46
Auto-ignition temperature: 202°C
Explosive limits, vol% in air: 1.3-28

ENVIRONMENTAL DATA


NOTES
An added stabilizer or inhibitor can influence the toxicological properties of this substance, consult an expert. Check for peroxides prior to distillation; eliminate if found. Vinamar and Agrisynth eve are trade names.
