HAZARD DATA - READ THIS BEFORE GOING ANY FURTHER!!!!
DIBUTYL ETHER:
IRRATATING TO EYES, SKIN, AND RESPIRATORY TRACT
FORMS EXPLOSIVE PEROXIDES
FLAMMABLE
Colourless liquid; b.p. 142ºC; immiscible with water. Liable to form explosive peroxides on exposure to light/air.
Peroxides removed by treatment with aqueous sodium metabisulfite. Avoid breathing vapour. avoid skin/eye
contact.
Toxic effects:The vapour is somewhat irritating to the respiratory system. The liquid irritates the eyes
and is hazardous by skin absorption.
Hazardous reactions:Peroxide formation can result in subsequent explosion. Powerful oxidants can cause
explosion.
Fire Hazard:Flash point 25ºC, ignition temp. 194ºC; extinguish fire with CO2.
Spillage & disposal:Wear face shield, goggles and gloves. Absorb bulk quantities on sand, shovel into
containers and remove to a chemical disposal skip. Wash site of spillage with plenty of
water and detergent.
TETRAHYDROFURAN:
IRRITATING TO EYES AND RESPIRATORY TRACT
MAY FORM EXPLOSIVE PEROXIDES
HIGHLY FLAMMABLE
Colourless volatile liquid with ethereal odour; b.p. 66ºC; miscible with water. Liable to form explosive peroxides
on exposure to light/air. Peroxides removed by treatment with aqueous sodium metabisulfite. Avoid breathing
vapour, eye and skin contact. OEL 295 mgm-3.
Toxic effects:The vapour irritates eyes and respiratory system; high concentrations have narcotic
effect. Absorption or ingestion may cause liver damage.
Hazardous reactions:Explosive peroxides formed on exposure to air/light. NaOH/KOH can cause explosion
with peroxided material.
Fire hazard:Flash point -17ºC; ignition temp. 321ºC; extinguish fire with CO2.
Spillage & disposal:Clear area, shut off all sources of ignition. Wear goggles, gloves, and laboratory coat.
Mop up with plenty of water and run to waste. Organise effective ventilation and
evaporate remaining liquid.
FLUOROBENZENE:
HIGHLY FLAMMABLE
Colourless liquid, benzene like odour; b.p. 85ºC; m.p. -45ºC; immisible with water.
Toxic effects:Harmful by inhalation and skin contact. May be harmful by ingestion. Irratating to
eyes.
Hazardous reactions:Can react with oxidising reagents
Fire Hazard:Falsh point -15ºC, extinguish with CO2
Spillage & disposal:Wear face shield, goggles and gloves. Absorb bulk quantities on sand, shovel into
containers and remove to a chemical disposal skip. Wash site of spillage with plenty of
water and detergent.
