advice about whether to induce vomiting. If possible, do
not leave individual unattended.
INHALATION: If symptoms develop, immediately move
individual away from exposure and into fresh air. Seek
immediate medical attention. Keep person warm and
quiet. If person is not breathing, begin artificial
respiration. If breathing is difficult, administer oxygen.
EXTINGUISHING MEDIA: Use dry chemical, carbon dioxide,
or foam extinguishing materials.
HAZARDOUS DECOMPOSITION PRODUCTS: Carbon
dioxide, carbon monoxide, silicon oxides.
UNUSUAL FIRE AND EXPLOSION HAZARDS: Material is
volatile and readily gives off vapors which may travel
along the ground or be moved by ventilation and ignited
by pilot lights, flames, sparks, heaters, smoking, electric
motors, static discharge or other ignition sources at
locations near the material handling point.
SPECIAL FIRE FIGHTING PROCEDURES: Wear self-
contained breathing apparatus in positive pressure mode
with confined facepiece.
PERSONAL PRECAUTIONS, PROTECTIVE EQUIPMENT AND
EMERGENCY PROCEDURES: Use personal protective
equipment outlined in section 8 for normal handling of
this material. Remove all possible sources of ignition
from the vicinity. Ensure adequate ventilation and
minimize exposure to vapors. Evacuate personnel to safe
areas. For personal protection see section 8.
ENVIRONMENTAL PRECAUTIONS: Prevent release to the
environment if possible. Do not flush product into drains
or sewer lines.
MATERIALS FOR CONTAINMENT AND CLEAN-UP: Use a
nonflammable absorbent material for clean-up. Place in
container for disposal according to local regulations.
REFERENCE TO OTHER SECTIONS: For additional disposal
directions and reporting requirements, please refer to
Section 13.
PRECAUTIONS FOR SAFE HANDLING: Keep container
closed when not in use. Use good personal hygiene
practices in accordance with this material. Avoid getting
the product in eyes or on skin. Remove contaminated
clothing and clean before re-use. Wash hands before
eating or drinking.
Make sure there is adequate ventilation in order to
minimize exposure to possible vapors.
Keep away from heat and flame. Keep operating
temperatures of equipment below ignition temperatures
at all times. Use non-sparking tools.
Please wear appropriate personal protective equipment
for handling of this product as outlined in Section 8.
STORAGE: Store in a cool, dry location. Keep container
tightly closed. Do not store near heat, flame, strong
oxidants. Maintain adequate ventilation.
SPECIAL STORAGE CONSIDERATIONS: Even when emptied,
the containers may retain product residues (vapor
and/or liquid), and this may pose a static ignition hazard.
Sudden release of hot organic vapors or mists from
process equipment operating at elevated temperature
and pressure, or sudden ingress of air into vacuum
equipment, may result in ignition without presence of
obvious ignition sources. Any use of this product in
elevated temperature processes should be thoroughly
evaluated to establish and maintain safe operating
conditions.
EXPOSURE LIMITS: No exposure limits have been
established for this material.
ENGINEERING CONTROLS: In enclosed environments,
exhaust ventilation by explosion-proof mechanical
means may be necessary to control air contaminants
below specified exposure limits. Handle product in
accordance with good industrial hygiene and safety
practice.
PERSONAL PROTECTIVE EQUIPMENT: Please wear
appropriate person protective equipment for handling of
this product as indicated below.
EYE PROTECTION: Chemical splash goggles are advised.
SKIN PROTECTION: Use gloves of an appropriate material
(latex, nitrile or PVC gloves) to minimize exposure.
RESPIRATORY PROTECTION: Engineering or administrative
controls should be implemented to reduce exposure
during normal handling of this product. If the workplace
