First-aid measures

General information

Take off contaminated clothing and shoes immediately. In the case of accident or if you feel unwell,

seek medical advice immediately (show the label where possible). In case of shortness of breath,

give oxygen. Keep victim warm. Keep victim under observation. Ensure that medical personnel are

aware of the material(s) involved, and take precautions to protect themselves.

Description of first aid measures

Inhalation

Move to fresh air. For breathing difficulties, oxygen may be necessary. Induce artificial respiration

with the aid of a pocket mask equipped with a one-way valve or other proper respiratory medical

device. Do not use mouth-to-mouth method if victim inhaled the substance. Get medical attention if

symptoms occur.

Skin conatct

Remove and isolate contaminated clothing and shoes. Wash off with warm water and soap. For

minor skin contact, avoid spreading material on unaffected skin. Get medical attention if irritation

develops and persists.

Eye contact

Immediately flush eyes with plenty of water for at least 15 minutes. Remove contact lenses, if

present and easy to do. Get medical attention if symptoms occur. Continue rinsing.

Ingestion

IF SWALLOWED: Immediately call a POISON CENTRE or doctor/physician. Never give anything by

mouth to a victim who is unconscious or is having convulsions. If swallowed, rinse mouth with

water (only if the person is conscious). Do not induce vomiting without advice from poison control

center. If vomiting occurs, keep head low so that stomach content doesn't get into the lungs.

Most important symptoms and effects, both acute and delayed

Inhalation of vapours or mists of the product may be irritating to the respiratory system.

Indication of any immediate medical attention and special treatment needed

In case of shortness of breath, give oxygen. Keep victim warm. Keep victim under observation.

Provide general supportive measures and treat symptomatically. Symptoms may be delayed.

Fire-fighting measures

General fire hazards

Material can accumulate static charges from material handling management. Bond and ground as

appropriate while recognizing that bonding and grounding alone may be insufficient to eliminate the

potential hazard from static-accumulating flammable liquids. For additional recommendations,

consult an applicable guideline such as National Fire Protection Association [NFPA] 77,

"Recommended Practices on Static Electricity" and API RP “Recommended Practice 2003, Protection

Against Ignitions Arising out of Static, Lightning, and Stray Currents” (2008). NOTE: The Lower

Explosive Limit [LEL] for organic liquids can range from as low as 0.5 - 1%.

Extinguishing media

Suitable extinguishing media

Water fog. Foam. Dry chemical powder. Carbon dioxide (CO2).

Unsuitable extinguishing media

Do not use water jet as an extinguisher, as this will spread the fire.

Special hazards arising from the substance or mixture

Fire may produce irritating, corrosive and/or toxic gases.

Advice for firefighters

Special protective equipment for firefighteners

Firefighters must use standard protective equipment including flame retardant coat, helmet with

face shield, gloves, rubber boots, and in enclosed spaces, SCBA. Structural firefighters protective

clothing will only provide limited protection.

Special fire fighting procedures

In case of fire and/or explosion do not breathe fumes. For massive fire in cargo area, use

unmanned hose holder or monitor nozzles, if possible. If not, withdraw and let fire burn out. In the

event of fire, cool tanks with water spray. ALWAYS stay away from tanks engulfed in flame.

Withdraw immediately in case of rising sound from venting safety device or any discolouration of

tanks due to fire. Move containers from fire area if you can do so without risk. Firefighters must use

standard protective equipment including flame retardant coat, helmet with face shield, gloves,

rubber boots, and in enclosed spaces, SCBA. Vapors may be heavier than air and may travel along

the ground to some distant source of ignition and flash back.

Specific methods

In the event of fire and/or explosion do not breathe fumes. Cool containers exposed to flames with

water until well after the fire is out.

Accidental release measures

Personal precautions, protective equipment and emergency procedures

For non-emergency personnel

Keep people away from and upwind of spill/leak. Avoid inhalation of vapours and spray mists. Keep

out of low areas. Do not touch damaged containers or spilled material unless wearing appropriate

protective clothing. Ventilate closed spaces before entering them. Follow facility/company's

emergency plans.

For emergency responders

Do not touch damaged containers or spilled material unless wearing appropriate protective clothing.

Keep upwind. Avoid inhalation of vapours and spray mists. Wear appropriate protective equipment

and clothing during clean-up. Remove all sources of ignition. Ventilate closed spaces before

entering them.

Environmental precautions

Prevent further leakage or spillage if safe to do so. Eliminate sources of ignition. Ventilate the

contaminated area. Prevent spreading over a wide area (e.g. by containment or oil barriers).

Prevent entry into waterways, sewer, basements or confined areas. In the event of a spill or

accidental release, notify relevant authorities in accordance with all applicable regulations.

Methods and material for containment and cleaning up

Eliminate ignition sources including sources of electrical, static or frictional sparks. Ventilate the

contaminated area. Extinguish all flames in the vicinity. Wear appropriate protective equipment and

clothing during clean-up.

Large Spills: Dike the spilled material, where this is possible. Cover with plastic sheet to prevent

spreading. Use a non-combustible material like vermiculite, sand or earth to soak up the product

and place into a container for later disposal. Clean surface thoroughly to remove residual

contamination.

Small Spills: Wipe up with absorbent material (e.g. cloth, fleece). Clean surface thoroughly to

remove residual contamination. This material is classified as a water pollutant under the Clean

Water Act and should be prevented from contaminating soil or from entering sewage and drainage

systems which lead to waterways.

Handling and storage

Precautions for safe handling

DO NOT handle, store or open near an open flame, sources of heat or sources of ignition. Protect

material from direct sunlight. All equipment used when handling the product must be grounded.

Use good personal hygiene practices Avoid breathing dust/fume/gas/mist/vapours/spray. Do not

get this material in contact with eyes. Do not get this material in contact with skin. Do not get this

material on clothing. Wear personal protective equipment. Do not use in areas without adequate

ventilation. Avoid prolonged exposure. Wash thoroughly after handling. "Empty" containers retain

product residue (liquid or vapour) and can be dangerous. Do not re-use empty containers.

Conditions for safe storage, including any incompatibilities

Use care in handling/storage. The pressure in sealed containers can increase under the influence of

heat. Keep away from heat and sources of ignition. This material can accumulate static charge

which may cause spark and become an ignition source. Prevent electrostatic charge build-up by

using common bonding and grounding techniques. Store in a well-ventilated place. Keep container

tightly closed.

Never return spills in original containers for re-use.

Exposure controls / personal protection

Appropriate engineering controls

Ensure adequate ventilation, especially in confined areas. Ventilation should be sufficient to

effectively remove, and prevent buildup of, any vapors, dusts, or fumes that may be generated

during handling or thermal processing. In order to ensure appropriate electrical safety practices are

followed, consult applicable standards. These may include guidelines such as the National Fire

Protection Association [NFPA] 70, "The National Electrical Code" and NFPA 499, "Recommended

Practice for the Classification of Combustible Dusts and of Hazardous (Classified) Locations for

Electrical Installations in Chemical Process Areas ". NOTE: since this material's vapors, dust or

fumes can form explosive mixtures in air, ensure that any potential areas where explosions may

occur are designed to minimize potential damage. For recommendations to prevent such

explosions and associated damage, consult applicable guidelines such as NFPA 69, "Standard on

Explosion Prevention Systems" and/or NFPA 68, "Guide for Venting Deflagrations".
