STYRENE:
HARMFUL BY INGESTION AND INHALATION
IRRITATING TO EYES, SKIN AND RESPIRATORY SYSTEM
POTENTIAL CARCINOGEN

Colourless or pale yellow oily liquid with a penetrating odour; b.p. 146ºC, m.p. -33ºC. Practically insoluble in water. MEL 420 mg/m³

Toxic effects:Harmful by ingestion and inhalation. Irritating to skin, eyes and respiratory system.
Vapour is narcotic in high concentrations. Prolonged exposure may cause systemic
effects. Has been found to cause cancer in laboratory animals.Evidence of reproductive
effects.
Hazardous reactions:Sources of free radicals can cause runaway polymerisation. Can react vigorously with
oxidising materials, ferric chloride, alkali metals and butyllithium. Fire hazards:Flash point 32ºC, ignition temp. 490^oC; extinguish fire with foam, dry powder or CO₂. Spillage & disposal:Wear goggles and nitrile gloves in a well ventilated area. Absorb onto inert material and
package in containers for disposal.Wash site of spillage thoroughly with water and
detergent.

1-OCTENE:
FLAMMABLE

Colourless; b.p. 122-23ºC.

Toxic effects:None indicated.
Hazardous reactions:None indicated but likely to react with oxidising agents.
Fire hazards:Flash point 21ºC, ignition temp. not available; extinguish fire with dry powder. Spillage & disposal:Wear goggles and nitrile gloves in a well ventilated area. Absorb onto inert material and
package in containers for disposal.

SODIUM SULFITE:
HARMFUL BY INGESTION AND INHALATION
IRRITATING TO EYES, SKIN AND RESPIRATORY SYSTEM
POTENTIAL CARCINOGEN

Colourless deliquescent crystals or white powder; m.p. n/a. Very soluble in water. MELnot assigned.

Toxic effects:Irritating to skin, eyes and respiratory system. If ingested in quantity can cause gastric
irritation, colic, diarrhoea, central nervous system depression and death, due to liberation
of sulfur dioxide.
Hazardous reactions:Sources of free radicals can cause runaway polymerisation. Can react vigorously with
oxidising materials, ferric chloride, alkali metals and butyllithium. Fire hazards:May evolve toxic fumes in a fire.
Spillage & disposal:Wear goggles and rubber gloves in a well ventilated area. Mop up with plenty of water
and run to waste with copious water. Larger spillages should be placed in containers for
disposal.
