DICHLOROMETHANE:
HARMFUL BY INHALATION,
INGESTION, AND SKIN CONTACT
POSSIBLE RISK OF IRREVERSIBLE
EFFECTS
IRRITATING TO EYES
Colourless volatile
liquid with chloroform-like odour; b.p. 40ºC; immiscible
with water. Avoid
breathing vapour. Avoid contact with skin and eyes. MEL 350
mgm-3.
Toxic effects:The vapour irritates the eyes and respiratory
system and may cause headaches and nausea;
high concentrations may result in cyanosis and
unconsciousness. The liquid irritates the
eyes. Poisonous if taken by mouth.
Hazardous reactions:Mixtures with Li, Na, N2O4,
HNO3liable to
explode.
Spillage &
disposal:Wear
goggles, gloves, and laboratory coat. Absorb bulk quantities on
sand, shovel into
buckets. Wash
site of spillage with water and detergent. Dichloromethane should be
placed in chlorinated waste contyainers for
central disposal
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.
Fire HazardFlash
point -45ºC, ignition temp. 180ºC; extinguish fire
with CO2. Hazardous
reactionsPeroxide
formation can result in subsequent explosion. Powerful oxidants can cause
explosion. Reacts vigorously with sulfuryl
chloride.
Spillage &
disposalClear area,
shut off all sources of ignition. Organise effective
ventilation and allow to
evaporate. Diethyl ether should be placed in the
non-chlorinated wastecontainer for
central disposal
1,4-DIOXAN:
HARMFUL BY INHALATION,
INGESTION, AND SKIN CONTACT
MAY FORM EXPLOSIVE
PEROXIDES
HIGHLY FLAMMABLE
Colourless almost
odourless liquid; b.p. 101ºC; miscible with water. Liable to form explosive peroxides
on exposure to light/air.
Peroxides removed by treatment with aqueous sodium
metabisulfite. Irritating to eyes. Avoid breathing vapour. OEL
90 mgm-3.
Toxic effects:The vapour irritates nose and eyes and this may be
followed by headache and drowsiness.
High concentrations may also cause nausea and
vomiting, while injury to the liver and
kidney is possible. Similar effects when taken by
mouth.
