IDENTIFICATION
EMERGENCY
OVERVIEW
Harmful by inhalation, in
contact with skin and if swallowed.
Irritating to eyes and skin.
Potential Health Effects
Eye:
Causes eye irritation.
May cause transient corneal injury.
Skin:
Causes skin
irritation. Substance is rapidly absorbed through
the skin. Causes symptoms similar to those of
inhalation. May be harmful if absorbed
through the skin.
Ingestion:
May cause
gastrointestinal irritation with nausea, vomiting
and diarrhea. May be harmful if swallowed.
Inhalation:
Inhalation
of
high
concentrations
may
cause
central
nervous
system
effects
characterized
by
nausea,
headache,
dizziness,
unconsciousness
and
coma.
May
cause
respiratory
tract
irritation.
May
be
harmful
if
inhaled.
Chronic:
May cause liver and kidney damage.
Chronic exposure may cause blood effects. Chronic
exposure may cause
effects similar to
those of acute exposure.
Section 4 -
FIRST AID MEASURES
Eyes: In
case of contact, immediately flush eyes with
plenty of water for at least 15 minutes. Get
medical aid
immediately.
Skin:
In case of contact,
flush skin with plenty of water. Remove
contaminated clothing and shoes. Get medical aid
if
irritation develops and persists.
Wash clothing before reuse.
Ingestion:
If swallowed,
do not induce vomiting unless directed to do so by
medical personnel. Never give anything by
mouth to an unconscious person. Get
medical aid.
Inhalation:
If
inhaled, remove to fresh air. If not breathing,
give artificial respiration. If breathing is
difficult, give oxygen.
Get medical
aid.
Notes to Physician:
Section 5 - FIRE FIGHTING
MEASURES
General
Information:
As
in
any
fire,
wear
a
self-contained
breathing
apparatus
in
pressure-demand,
MSHA/NIOSH
(approved
or
equivalent), and full protective gear.
During a fire, irritating and highly toxic gases
may be generated by thermal
decomposition or combustion. Use water
spray to keep fire-exposed containers cool.
Combustible liquid and
vapor. Vapors
are heavier than air and may travel to a source of
ignition and flash back. Vapors can spread
along the ground and collect in low or
confined areas.
Extinguishing Media:
Water may be ineffective. Do NOT use
straight streams of water. For small fires, use
dry chemical, carbon
dioxide, or water
spray. For large fires, use water spray, fog or
regular foam.
Section 6 - ACCIDENTAL
RELEASE MEASURES
General
Information: Use proper personal protective
equipment as indicated in Section 8.
Spills/Leaks:
Absorb spill
with inert material (e.g. vermiculite, sand or
earth), then place in suitable container. Avoid
runoff
into
storm sewers and ditches which lead to waterways.
Clean up spills immediately, observing precautions
in
the Protective Equipment section.
Remove all sources of ignition. Use a spark-proof
tool. Provide ventilation.
Section 7 -
HANDLING and STORAGE
Handling:
Wash thoroughly
after handling. Remove contaminated clothing and
wash before reuse. Use with adequate
ventilation.
Ground
and
bond
containers
when
transferring
material.
Avoid
contact
with
eyes,
skin,
and
clothing.
Empty
containers
retain
product
residue,
(liquid
and/or
vapor),
and
can
be
dangerous.
Do
not
pressurize, cut, weld,
braze, solder, drill, grind, or expose empty
containers to heat, sparks or open flames.
Keep away from heat and flame. Avoid
breathing vapor or mist.
