5. FIRE-FIGHTING MEASURES
EXTINGUISHING MEDIA
Suitable Extinguishing Media: Foam, dry chemical, carbon dioxide (CO2)Inappropriate Media: Straight streams of water
SPECIFIC HAZARDS ARISING FROM THE CHEMICALSSpecific Hazards Arising from the Chemicals: Flammable liquid Material can release flammablevapours. Vapours are heavier than air. Vapours may travel across the ground and reach remote ignition
sources causing a flashback fire danger. As material is hazardous, firefighters should consider protective
equipment indicated in Section 8.
Hazardous Combustion Products:
Incomplete combustion products, carbon monoxide, smoke, fume
SPECIFIC PROTECTIVE ACTIONS FOR FIRE-FIGHTERS
Specific protective actions for fire-fighter:
Firefighters should use standard protective equipment and in enclosed spaces, self-contained breathingapparatus (SCBA). Use water spray to cool fire exposed surfaces and to protect personnel.
Fire Fighting Instructions:
Evacuate non-emergency personal to safe area. Extinguish fire with appropriate media. Stop leak if you
can do it without risk.
Move container if you can do it without risk. Use water spray or fog for coolingtanks or containers surround fire. If a leak or spill has not ignited, use water spray to disperse the vapors
and to protect personnel attempting to stop a leak or to move container. Prevent runoff from fire control or
dilution from entering streams, sewers, or drinking water supply.

6. ACCIDENTAL RELEASE MEASURESPERSONAL PRECAUTIONS, PROTECTIVE EQUIPMENT AND EMERGENCY PROCEDURES
Avoid contact with spilled material. Warn or evacuate occupants in surrounding and downwind areas if
required due to toxicity or flammability of the material. See Section 5 for fire fighting information. See theHazard Identification Section for Significant Hazards. See Section 4 for First Aid Advice. See Section 8
for advice on the minimum requirements for personal protective equipment. Additional protective measures
may be necessary, depending on the specific circumstances and/or the expert judgment of the emergency
responders.
For emergency responders: Respiratory protection: half-face or full-face respirator with filter(s) for spilledmaterial and, when applicable, Self Contained Breathing Apparatus (SCBA) can be used depending on thesize of spill and potential level of exposure. If the exposure cannot be completely characterized or an
oxygen deficient atmosphere is possible or anticipated, SCBA is recommended.
Work gloves that are resistant to oil are recommended. Note: gloves made of polyvinyl alcohol (PVA) are
not water-resistant and are not suitable for emergency use. Chemical goggles are recommended if
splashes or contact with eyes is possible. Small spills: normal antistatic work clothes are usually adequate.
Large spills: full body suit of chemical resistant, antistatic material is recommended.
Notification Procedures
In the event of a spill or accidental release, notify relevant authorities in accordance with all applicableregulations. Evacuate non-emergency personal to safe area. Material is toxic or combustible. Advise
occupants surrounding or in downwind areas to warn them to evacuate, if needed.
ENVIRONMENTAL PRECAUTIONS
Large Spills: Dike far ahead of liquid spill for later recovery and disposal.
sewers, basements or confined areas.

Prevent entry into waterways,

METHODS AND MATERIALS FOR CONTAINMENT AND CLEANING UP
Land Spill:
Eliminate all ignition sources (no smoking, flares, sparks or flames in immediate area).
Stop leak if you can do it without risk. All equipment used when handling the product must be grounded.
Use explosion-proof equipment and non-sparking tools.
Do not touch or walk through spilled material. Collect with pump, absorb or cover with dry earth, sand orother non-combustible material and transfer to containers.
Prevent spreading of vapors through sewers,

ventilation systems and confined areas. A vapor suppressing foam may be used to reduce vapors. Water
spray may reduce vapor; but may not prevent ignition in closed spaces.
Water Spill:
Stop leak if you can do it without risk. Eliminate sources of ignition. Warn other shipping.
If the Flash Point exceeds the Ambient Temperature by 10℃ or more, use containment booms and remove
from the surface by skimming or with suitable absorbents when conditions permit. If the Flash Point does
not exceed the Ambient Air Temperature by at least 10℃, use booms as a barrier to protect shorelines andallow material to evaporate. Seek the advice of a specialist before using dispersants.
Water spill and land spill recommendations are based on the most likely spill scenario for this material;
however, geographic conditions, wind, temperature, (and in the case of a water spill) wave and current
direction and speed may greatly influence the appropriate action to be taken. For this reason, local experts
should be consulted. Note: Local regulations may prescribe or limit action to be taken.

7. HANDLING AND STORAGE
PRECAUTIONS FOR SAFE HANDLING
Prevent small spills and leakage to avoid slip hazard. Material can accumulate static charges which may
cause an electrical spark (ignition source). When the material is handled in bulk, an electrical spark could
ignite any flammable vapors from liquids or residues that may be present. Use proper bonding and/or
ground procedures. However, bonding and grounds may not eliminate the hazard from static accumulation.
Consult local applicable standards for guidance.
Potentially toxic/irritating fumes/vapors may be evolved from heated or agitated material. Use only withadequate ventilation. Prevent small spills and leakage to avoid slip hazard.
Material can accumulate static charges. When the material is handled in bulk, an electrical spark could
ignite any flammable vapors from liquids or residues that may be present. Use proper bonding and/or
ground procedures.
Avoid contact with material.
CONDITION FOR SAFE STORAGE, INCLUDING ANY INCOMPATIBILITIES
Ample fire water supply should be available. A fixed sprinkler/deluge system is recommended. Keep
container closed. Handle containers with care. Open slowly in order to control possible pressure release.
Store in a cool, well-ventilated area.
Outside or detached storage preferred. Keep away fromincompatible material. The container choice, for example storage vessel, may effect static accumulationand dissipation. Storage containers should be grounded and bonded. Fixed storage containers, transfer
containers and associated equipment should be grounded and bonded to prevent accumulation of static
charge.
Suitable Materials and Coatings (Chemical Compatibility):
Stainless Steel, Steel, Teflon, Polyester
Unsuitable Materials and Coatings:
Rubber, Polystyrene, Ethylene-Propylene rubber, Polyethylene

INDIVIDUAL PROTECTION MEASURES, SUCH AS PERSONAL PROTECTIVE EQUIPMENT (PPE)
Personal protective equipment selections vary based on potential exposure conditions such as applications,handling practices, concentration and ventilation. Information on the selection of protective equipment for
use with this material, as provided below, is based upon intended, normal usage. Any specific protective
equipment information provided is based on published literature and protective equipment manufacturer
data.
Eye/Face Protection:
If contact is likely, safety face protections are recommended.
Skin and Body Protection:
The types of clothing to be considered for this material include: Chemical resistant clothing(non-permeable) is needed.

Respirator selection, use, andmaintenance must be in accordance with regulatory requirements, if applicable. Types of respirators to beconsidered for this material include: for organic vapour/gas
For high airborne concentrations, use an approved supplied-air respirator, operated in positive pressuremode. Supplied air respirators with an escape bottle may be appropriate when oxygen levels are
inadequate, if concentration is high, gas/vapor warning properties are poor, or if air purifying filter
capacity/rating may be exceeded.
Hand Protection:
Use suitable protective glove. Glove suitability and breakthrough time will differ depending on the specificuse conditions. Contact the glove manufacturer for specific advice on glove selection and breakthroughtimes for your use conditions. Inspect and replace worn or damaged gloves. The types of gloves to beconsidered for this material include:
Chemical resistant gloves(non-permeable) are needed. If contact with forearms is likely, wear gauntlet
style gloves.
