sensation of the nose and throat, coughing, and/or difficulty
breathing. If material enters lungs, signs and symptoms may
include coughing, choking, wheezing, difficulty in breathing,
chest congestion, shortness of breath, and/or fever. Breathing
of high vapour concentrations may cause central nervous
system (CNS) depression resulting in dizziness, light-
headedness, headache, nausea and loss of coordination.
Continued inhalation may result in unconsciousness and death.

6. ACCIDENTAL RELEASE MEASURES
Observe all relevant local and international regulations.
: Avoid contact with spilled or released material. Immediately
Protective measures
remove all contaminated clothing. For guidance on selection of
personal protective equipment see Chapter 8 of this Material
Safety Data Sheet. For guidance on disposal of spilled material
see Chapter 13 of this Material Safety Data Sheet. Shut off
leaks, if possible without personal risks. Remove all possible
sources of ignition in the surrounding area. Use appropriate
containment (of product and fire fighting water) to avoid
environmental contamination. Prevent from spreading or
entering drains, ditches or rivers by using sand, earth, or other
appropriate barriers. Attempt to disperse the vapour or to direct
its flow to a safe location for example by using fog sprays.
Take precautionary measures against static discharge. Ensure
electrical continuity by bonding and grounding (earthing) all
equipment. Monitor area with combustible gas indicator.
: For large liquid spills (> 1 drum), transfer by mechanical means
Clean Up Methods
such as vacuum truck to a salvage tank for recovery or safe
disposal. Do not flush away residues with water. Retain as
contaminated waste. Allow residues to evaporate or soak up
with an appropriate absorbent material and dispose of safely.
Remove contaminated soil and dispose of safely.
For small liquid spills (< 1 drum), transfer by mechanical means
to a labelled, sealable container for product recovery or safe
disposal. Allow residues to evaporate or soak up with an
appropriate absorbent material and dispose of safely. Remove
contaminated soil and dispose of safely.
: See Chapter 13 for information on disposal. Notify authorities if

any exposure to the general public or the environment occurs
or is likely to occur. Vapour may form an explosive mixture with
air. U.S. regulations may require reporting releases of this
material to the environment which exceed the reportable
quantity (refer to Chapter 15) to the National Response Centre
at (800) 424-8802.
7. HANDLING AND STORAGE
: Avoid breathing of or contact with material. Only use in well

ventilated areas. Wash thoroughly after handling. For
guidance on selection of personal protective equipment see
Chapter 8 of this Material Safety Data Sheet. Use the
information in this data sheet as input to a risk assessment of
local circumstances to help determine appropriate controls for
safe handling, storage and disposal of this material.
: Avoid contact with the skin. Electrostatic charges may be

Hand Protection
Suitability and durability of a glove is dependent on usage, e.g.
frequency and duration of contact, chemical resistance of glove
material, glove thickness, dexterity. Always seek advice from
glove suppliers. Contaminated gloves should be replaced.
