CHLOROBENZENE:
FLAMMABLE
HARMFUL BY INHALATION
Colourless liquid, faint almond odour; b.p. 132ºC; m.p. -56ºC; immisible with water. Avoid skin or eye contact. Avoid breathing vapour. OEL 230 mgm^-3

Toxic effects:Harmful by ingestion and inhalation. Irritating to skin and eyes. Hazardous reactions:Can react with oxidising reagents
Fire hazard:Flash point 29ºC, 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.

ANISOLE:
FLAMMABLE
IRRATATING TO EYES, SKIN, AND RESPIRATORY TRACT Pale yellow liquid, aromatic odour; b.p. 155ºC; m.p. -37ºC; immisible with water.Avoid inhalation of vapour Toxic effects:Harmful by ingestion and inhalation. Irritating to skin and eyes Hazardous reactions:Can react with oxidising reagents
Fire Hazard:Falsh point 41ºC, 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.

CHROMIUM HEXACARBONYL:
HIGHLY TOXIC BY INGESTION, INHALATION
MAY CAUSE CANCER
Colourless volatile crystals, m.p. 150ºC (dec); immiscible with water. Avoid skin/eye contact. Avoid breathing vapour. OEL 0.24 mgm-³[assessed as Ni(CO)₄]

Toxic effects:Highly toxic by inhalation. Avoid all exposure. Handle only in an efficient fume
cupboard.
Spillage & disposal:Do not attempt to deal with a spillage. Call a Demonstrator or Technician
immediately.

DIETHYL ETHER:
HARMFUL BY INHALATION, AND INGESTION
MAY FORM EXPLOSIVE PEROXIDES
EXTREMELY FLAMMABLE
Colourless highly volatile liquid with characteristic odour; b.p. 34ºC; immiscible with water. Liable to form explosive peroxides on exposure to light/air. Peroxides removed by treatment with aqueous sodium metabisulfite. Avoid breathing vapour. OEL 1200 mgm^-3.

Toxic effects:Inhalation of the vapour may cause drowsiness, dizziness, mental confusion, faintness
and, in high concentrations, unconsciousness. Ingestion may also produce these effects.
Continued inhalation of low concentrations may cause loss of appetite, dizziness,
fatigue and nausea.
Hazardous reactionsPeroxide formation can result in subsequent explosion. Powerful oxidants can cause
explosion. Reacts vigorously with sulfuryl chloride.
Fire HazardFlash point -45ºC, ignition temp. 180ºC; extinguish fire with CO₂.
