Fire
hazardFlash point
12ºC; ignition temp. 180ºC; extinguish fire with
CO2.
Hazardous
reactions:Explosive
peroxides formed on exposure to air/light. Reacts explosively
with Raney Ni
at >210ºC.
Addition complex with SO3explodes on storage.
Spillage &
disposalClear area,
shut off all sources of ignition. Wear goggles, gloves, and
laboratory coat.
Mop up with plentyof water and run to waste. Organise effective ventilation and
evaporate remaining liquid. 1,4-Dioxan should be placed in the
non-chlorinated waste
container for central disposal.
ETHYL ACETATE:
HIGHLY FLAMMABLE
IRRITATING TO EYES AND
RESPIRATORY SYSTEM
Colourless liquid with fragrant odour; b.p. 77ºC; slightly
soluble in water. Avoid
breathing vapour. Avoid
eye contact. OEL 1400 mgm-3.
Toxic effects:The vapour may irritate the eyes and respiratory
system. The liquid irritates the eyes and
mucous surfaces. Prolonged inhalation may cause
kidney and liver damage. Fire hazard:Flash point -4.4ºC; ignition
temp. 427ºC; extinguish fire with CO2. Spillage &
disposal:Clear area,
shut off all sources of ignition. Wear face shield goggles and
gloves.
Absorb bulk quantities on sand, shovel into
buckets. Wash site of spillage with water
and detergent. Ethyl acetate should be placed in
the non-chlorinated waste container for
central disposal.
PHOSPHORIC ACID:
CORROSIVE
CAUSES BURNS
Colourless viscous liquid, miscible with water. Avoid eye
contact. OEL 2 mgm-3.
Toxic effects:The liquid burns the eyes and skin severely.
If taken by mouth, there
would be severe
internal damage.
Spillage &
disposal:Wear
goggles, gloves, and laboratory coat. Carefully spread sodium carbonate liberally
over thespillage and mop up cautiously with plenty of water.
Run to waste with
running water.
PYRIDINE:
HARMFUL BY INHALATION,
INGESTION, AND SKIN CONTACT
IRRITATING TO EYES, SKIN AND
RESPIRATORY SYSTEM
HIGHLY FLAMMABLE
Colourless liquid with
a sharp penetrating odour; b.p. 115ºC; miscible with
water.Avoid breathing
vapour. Avoid contact with
skin and eyes. OEL 2 mgm-3.
Toxic effects:The vapour irritates the respiratory system and may
cause headache, nausea, giddiness
and vomiting. The vapour and liquid irritates the
eyes and may cause conjunctivitis. the
liquid may irritate the skin and cause dermatitis.
Affects the central nervous system if
taken by mouth and large doses act as a heart
poison.
Fire hazard:Flash
point 20ºC, ignition temp. 482ºC; extinguish fire
with CO2. Hazardous reactions:Complex with CrO3unstable and decomposes violently
when dry. Reacts violently
with N2O4.
