SECTION 4 FIRST AID MEASURES
Eye: Flush eyes with running water immediately while holding the eyelids open. Remove contact lenses, if worn, after initial
flushing, and continue flushing for at least 15 minutes. Get immediate medical attention.
Skin: To remove the material from skin, use soap and water. Discard contaminated clothing and shoes or thoroughly
clean before reuse. Get medical attention if any symptoms develop.
Ingestion: If swallowed, do not induce vomiting. Give the person a glass of water or milk to drink and get immediate
medical attention. Never give anything by mouth to an unconscious person.
Inhalation: Move the exposed person to fresh air. If not breathing, give artificial respiration. If breathing is difficult, give
oxygen. Get medical attention if breathing difficulties continue.
SECTION 5 FIRE FIGHTING MEASURES
FIRE CLASSIFICATION:
OSHA Classification (29 CFR 1910.1200): Not classified by OSHA as flammable or combustible.
NFPA RATINGS: Health: 1 Flammability: 1 Reactivity: 0
FLAMMABLE PROPERTIES:
Flashpoint: 166癈 (330.8癋) (Cleveland Open Cup)
Autoignition: NDA
Flammability (Explosive) Limits (% by volume in air): Lower: NDA Upper: NDA
EXTINGUISHING MEDIA: Use water fog, foam, dry chemical or carbon dioxide (CO2) to extinguish flames.
PROTECTION OF FIRE FIGHTERS:
Fire Fighting Instructions: Material will not burn unless preheated. Clear fire area of all non-emergency personnel. Only
enter confined fire space with full gear, including a positive pressure, NIOSH-approved, self-contained breathing
apparatus. Cool surrounding equipment, fire-exposed containers and structures with water. Container areas exposed to
direct flame contact should be cooled with large quantities of water (500 gallons water per minute flame impingement
exposure) to prevent weakening of container structure.
Combustion Products: Highly dependent on combustion conditions. A complex mixture of airborne solids, liquids, and
gases including carbon monoxide, carbon dioxide, and unidentified organic compounds will be evolved when this material
undergoes combustion.
SECTION 6 ACCIDENTAL RELEASE MEASURES
Protective Measures: Eliminate all sources of ignition in vicinity of spilled material. Wear appropriate personal protective
equipment when cleaning up spills. Refer to Section 8.
Spill Management: Stop the source of the release if you can do it without risk. Contain release to prevent further
contamination of soil, surface water or groundwater. Clean up spill as soon as possible, observing precautions in
Exposure Controls/Personal Protection. Use appropriate techniques such as applying non-combustible sorbent materials
or pumping. Where feasible and appropriate, remove contaminated soil. Place contaminated materials in disposable
containers and dispose of in a manner consistent with applicable regulations.
Reporting: U.S.A. regulations may require reporting spills of this material that could reach any surface waters. Report
spills to local authorities and/or the National Response Center at (800) 424-8802 as appropriate or required.
SECTION 7 HANDLING AND STORAGE
READ AND OBSERVE ALL PRECAUTIONS ON PRODUCT LABEL . REFER TO PRODUCT LABEL OR MANUFACTURERS
TECHNICAL BULLETINS FOR THE PROPER USE AND HANDLING OF THIS MATERIAL .
Precautionary Measures: Do not get in eyes. Do not taste or swallow. Do not breathe vapor or fumes. Avoid
contaminating soil or releasing this material into sewage and drainage systems and bodies of water. General Handling
Information: Wash with soap and water before eating, drinking, smoking, applying cosmetics, or using toilet facilities.

Launder contaminated clothing before reuse.
Static Hazard: Electrostatic charge may accumulate and create a hazardous condition when handling this material. To
minimize this hazard, bonding and grounding may be necessary but may not, by themselves, be sufficient. Review all
operations, which have the potential of generating an accumulation of electrostatic charge and/or a flammable atmosphere
(including tank and container filling, splash filling, tank cleaning, sampling, gauging, switch loading, filtering, mixing,
agitation, and vacuum truck operations) and use appropriate mitigating procedures. For more information, refer to OSHA
Standard 29 CFR 1910.106, 'Flammable and Combustible Liquids, National Fire Protection Association (NFPA 77),
Recommended Practice on Static Electricity' (liquids, powders and dusts), and/or the American Petroleum Institute (API)
Recommended Practice 2003, 'Protection Against Ignitions Arising Out of Static, Lightning, and Stray Currents' (liquids).
Container Warnings: Container is not designed to contain pressure. Do not use pressure to empty container or it may
rupture with explosive force. Empty containers retain product residue (solid, liquid, and/or vapor) and can be dangerous.
Do not pressurize, cut, weld, braze, solder, drill, grind, or expose such containers to heat, flame, sparks, static electricity,
or other sources of ignition. They may explode and cause injury or death. Empty containers should be completely
drained, properly closed, and promptly returned to a drum reconditioner or disposed of properly.
SECTION 8 EXPOSURE CONTROLS/PERSONAL PROTECTION
GENERAL CONSIDERATIONS:
Consider the potential hazards of this material (see Section 3), applicable exposure limits, job activities, and other
substances in the work place when designing engineering controls and selecting personal protective equipment. If
engineering controls or work practices are not adequate to prevent exposure to harmful levels of this material, the personal
protective equipment listed below is recommended. The user should read and understand all instructions and limitations
supplied with the equipment since protection is usually provided for a limited time or under certain circumstances.
ENGINEERING CONTROLS:
Use process enclosures, local exhaust ventilation, or other engineering controls to control airborne levels below the
recommended exposure limits.
PERSONAL PROTECTIVE EQUIPMENT:
Eye/Face Protection: Wear eye protection such as safety glasses, chemical goggles, or faceshields if engineering
controls or work practices are not adequate to prevent eye contact.
Skin Protection: Wear impervious protective clothing to prevent skin contact. Selection of protective clothing may include
gloves, apron, boots, and complete facial protection depending on operations conducted. Users should determine
acceptable performance characteristics of protective clothing. Consider physical requirements and other substances
present when selecting protective clothing. Suggested materials for protective gloves include: Neoprene, or Polyvinyl
Chloride (PVC)
Respiratory Protection: If exposure is anticipated to be greater than applicable exposure limits, wear a NIOSH approved
respirator that provides adequate protection from measured concentrations of this material, such as: Air-Purifying
Respirator for Organic Vapors
Use a positive pressure, air-supplying respirator if there is potential for uncontrolled release, exposure levels are not
known, or other circumstances where air-purifying respirators may not provide adequate protection.
Occupational Exposure Limits:
