TYPES OF HAZARD / EXPOSURE ACUTE HAZARDS / SYMPTOMS PREVENTION FIRST AID / FIRE FIGHTING
FIRE Highly flammable.
NO open flames, NO sparks, and NO smoking. NO contact with oxidants.
Foam, powder, carbon dioxide.
EXPLOSION Vapour/air mixtures are explosive.
Closed system, ventilation, explosion-proof electrical equipment and lighting. Do NOT use compressed air for filling, discharging, or handling.
In case of fire: keep drums, etc., cool by spraying with water.
EXPOSURE
STRICT HYGIENE!

Inhalation
Ventilation, local exhaust, or breathing protection.

Skin Redness.
Protective gloves. Protective clothing.
Remove contaminated clothes. Rinse skin with plenty of water or shower.
Eyes Redness.
Safety goggles 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
Do not eat, drink, or smoke during work.
Refer for medical attention.
SPILLAGE DISPOSAL PACKAGING & LABELLING

4-VINYLCYCLOHEXENE ICSC: 1177
IMPORTANT DATA
PHYSICAL STATE; APPEARANCE:
COLOURLESS LIQUID.

PHYSICAL DANGERS:
The vapour mixes well with air, explosive mixtures are easily formed.

CHEMICAL DANGERS:
The substance can form explosive peroxides. Reacts with oxidants causing fire and explosion hazard.

OCCUPATIONAL EXPOSURE LIMITS:
TLV: 0.1 ppm as TWA; A3 (confirmed animal carcinogen with unknown relevance to humans); (ACGIH 2004).
MAK: skin absorption (H); Carcinogen category: 2; (DFG 2005).
ROUTES OF EXPOSURE:
The substance can be absorbed into the body by inhalation of its vapour, 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 20C.

EFFECTS OF SHORT-TERM EXPOSURE:
The substance is irritating to the eyes and the skin.

EFFECTS OF LONG-TERM OR REPEATED EXPOSURE:
This substance is possibly carcinogenic to humans.
PHYSICAL PROPERTIES

Melting point: -109C
Relative density (water = 1): 0.829
Solubility in water: none
Vapour pressure, kPa at 38C: 3.43
Relative vapour density (air = 1): 3.7
Relative density of the vapour/air-mixture at 20C (air = 1): 1.09
Flash point: 16C c.c.
Auto-ignition temperature: 269C
Octanol/water partition coefficient as log Pow: 3.93
ENVIRONMENTAL DATA
Bioaccumulation of this chemical may occur along the food chain, for example in fish.
NOTES
Do NOT take working clothes home. 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. Card has been partly updated in October 2005. See sections Occupational Exposure Limits, Emergency Response.
