3. HAZARDS IDENTIFICATION

Potential Health Effects:

Eye: Contact may cause mild eye irritation including stinging, watering, and redness.

Skin: Severe skin irritant. Contact may cause redness, itching, burning, and severe skin damage.Prolonged or repeated contact can worsen irritation by causing drying and cracking of the skin, leadingto dermatitis (inflammation). Not acutely toxic by skin absorption, but prolonged or repeated skincontact may be harmful (see Section 11).

Inhalation (Breathing): No information available. Studies by other exposure routes suggesta low degree of toxicity by inhalation.

Ingestion (Swallowing): Low degree of toxicity by ingestion. ASPIRATION HAZARD - This material can enter lungs during swallowing or vomiting and cause lung inflammation and damage.

Signs and Symptoms: Effects of overexposure may include irritation of the nose and throat,irritation of the digestive tract, nausea, diarrhea and transient excitation followed by signs of nervoussystem depression (e.g., headache, drowsiness, dizziness, loss of coordination, disorientation andfatigue).

Cancer: Possible skin cancer hazard (see Sections 11 and 15).

Target Organs: There is limited evidence from animal studies that overexposure may cause injury to the kidney (see Section 11).

Developmental: Inadequate data available for this material.

Other Comments: This material may contain polynuclear aromatic hydrocarbons (PNAs) whichhave been known to produce a photototoxic reaction when contaminated skin is exposed to sunlight. The effect is similar in appearance to an exaggerated sunburn, and is temporary in duration if exposure isdiscontinued. Continued exposure to sunlight can result in more serious skin problems includingpigmentation (discoloration), skin eruptions (pimples), and possible skin cancers.

Pre-Existing Medical Conditions: Conditions aggravated by exposure may include skin disorders and kidney disorders.

4. FIRST AID MEASURES

Eye: If irritation or redness develops, move victim away from exposure and into fresh air. Flush eyeswith clean water. If symptoms persist, seek medical attention.

Skin: Immediately remove contaminated shoes, clothing, and constrictive jewelry and flush affectedarea(s) with large amounts of water. If skin surface is damaged, apply a clean dressing and seekimmediate medical attention. If skin surface is not damaged, cleanse affected area(s) thoroughly bywashing with mild soap and water. If irritation or redness develops, seek immediate medicalattention.

Inhalation (Breathing): If respiratory symptoms develop, move victim away from source of exposure and intofresh air. If symptoms persist, seek medical attention. If victim is not breathing, clear airway and immediatelybegin artificial respiration. If breathing difficulties develop, oxygen should be administered by qualifiedpersonnel. Seek immediate medical attention.

Ingestion (Swallowing): Aspiration hazard: Do not induce vomiting or give anything by mouth because thismaterial can enter the lungs and cause severe lung damage. If victim is drowsy or unconscious andvomiting, place on the left side with the head down. If possible, do not leave victim unattended and observeclosely for adequacy of breathing. Seek medical attention.

Note To Physicians: High-pressure hydrocarbon injection injuries may produce substantialnecrosis of underlying tissue despite an innocuous appearing external wound. Often these injuriesrequire extensive emergency surgical debridement and all injuries should be evaluated by aspecialist in order to assess the extent of injury.

5. FIRE FIGHTING MEASURES

Flammable Properties: Flash Point: 125-180°F/52-82°C PMCC, ASTM D-93OSHA Flammability Class: Combustible liquid LEL%: 0.3 / UEL%: 10.0Autoignition Temperature: 500°F/260°C

Unusual Fire & Explosion Hazards: This material is flammable and can be ignited by heat, sparks, flames, orother sources of ignition (e.g., static electricity, pilot lights, or mechanical/electrical equipment, and electronicdevices such as cell phones, computers, calculators, and pagers which have not been certified as intrinsicallysafe). Vapors may travel considerable distances to a source of ignition where they can ignite, flash back, orexplode. May create vapor/air explosion hazard indoors, in confined spaces, outdoors, or in sewers. Vapors areheavier than air and can accumulate in low areas. If container is not properly cooled, it can rupture in the heat of afire.

Extinguishing Media: Dry chemical, carbon dioxide, or foam is recommended. Water spray is recommended tocool or protect exposed materials or structures. Carbon dioxide can displace oxygen. Use caution when applyingcarbon dioxide in confined spaces. Water may be ineffective for extinguishment, unless used under favorableconditions by experienced fire fighters.

Fire Fighting Instructions: For fires beyond the incipient stage, emergency responders in the immediate hazardarea should wear bunker gear. When the potential chemical hazard is unknown, in enclosed or confined spaces, orwhen explicitly required by DOT, a self contained breathing apparatus should be worn. In addition, wear other appropriate protective equipment as conditions warrant (see Section 8).

Isolate immediate hazard area, keep unauthorized personnel out. Stop spill/release if it can be done with minimal

risk. Move undamaged containers from immediate hazard area if it can be done with minimal risk.

Water spray may be useful in minimizing or dispersing vapors and to protect personnel. Cool equipment exposed tofire with water, if it can be done with minimal risk. Avoid spreading burning liquid with water used for cooling purposes.

6. ACCIDENTAL RELEASE MEASURES

Flammable. Keep all sources of ignition and hot metal surfaces away from spill/release. The use of explosion-proof equipment is recommended.

Stay upwind and away from spill/release. Notify persons down wind of the spill/release, isolate immediate hazard area and keep unauthorized personnel out. Stop spill/release if it can be done with minimal risk. Wear appropriate protective equipment including respiratory protection as conditions warrant (see Section 8).

Prevent spilled material from entering sewers, storm drains, other unauthorized drainage systems, and natural waterways. Dike far ahead of spill for later recovery or disposal. Use foam on spills to minimize vapors (seeSection 5). Spilled material may be absorbed into an appropriate absorbent material.

Notify fire authorities and appropriate federal, state, and local agencies. Immediate cleanup of any spill isrecommended. If spill of any amount is made into or upon navigable waters, the contiguous zone, or adjoiningshorelines, notify the National Response Center (phone number 800-424-8802).

7. HANDLING AND STORAGE

Handling: Open container slowly to relieve any pressure. Bond and ground all equipment whentransferring from one vessel to another. Can accumulate static charge by flow or agitation. Can be ignitedby static discharge. The use of explosion-proof equipment is recommended and may be required (seeappropriate fire codes). Refer to NFPA-704 and/or API RP 2003 for specific bonding/grounding requirements.

Do not enter confined spaces such as tanks or pits without following proper entry procedures such as ASTMD-4276 and 29CFR 1910.146. The use of appropriate respiratory protection is advised when concentrationsexceed any established exposure limits (see Sections 2 and 8).

Do not wear contaminated clothing or shoes. Keep contaminated clothing away from sources of ignition suchas sparks or open flames. Use good personal hygiene practices.

High pressure injection of hydrocarbon fuels, hydraulic oils or greases under the skin may have seriousconsequences even though no symptoms or injury may be apparent. This can happen accidentally when usinghigh pressure equipment such as high pressure grease guns, fuel injection apparatus or from pinhole leaks intubing of high pressure hydraulic oil equipment.

"Empty" containers retain residue and may be dangerous. Do not pressurize, cut, weld, braze, solder, drill,grind, or expose such containers to heat, flame, sparks, or other sources of ignition. They may explode andcause injury or death. "Empty" drums should be completely drained, properly bunged, and promptly shipped tothe supplier or a drum reconditioner. All containers should be disposed of in an environmentally safemanner and in accordance with governmental regulations.

Before working on or in tanks which contain or have contained this material, refer to OSHA regulations, ANSIZ49.1 and other references pertaining to cleaning, repairing, welding, or other contemplated operations.

Storage: Keep container(s) tightly closed. Use and store this material in cool, dry, well-ventilatedareas away from heat, direct sunlight, hot metal surfaces, and all sources of ignition. Post area "No Smoking or Open Flame." Store only in approved containers. Keep away from any incompatible material (seeSection 10). Protect container(s) against physical damage. Outdoor or detached storage is preferred.Indoor storage should meet OSHA standards and appropriate fire codes.

8. EXPOSURE CONTROLS/PERSONAL PROTECTION

Engineering controls: If current ventilation practices are not adequate to maintain airborne concentrations belowthe established exposure limits (see Section 2), additional engineering controls may be required. Where explosivemixtures may be present, electrical systems safe for such locations must be used (see appropriate electricalcodes).

Personal Protective Equipment (PPE):

Respiratory: A NIOSH certified air purifying respirator with an organic vapor cartridge maybe used under conditions where airborne concentrations are expected to exceed exposurelimits (see Section 2).

Protection provided by air purifying respirators is limited (see manufacturer's respirator

selection guide). Use a NIOSH approved self-contained breathing apparatus (SCBA) orequivalent operated in a pressure demand or other positive pressure mode if there ispotential for an uncontrolled release, exposure levels are not known, or any othercircumstances where air purifying respirators may not provide adequate protection.

A respiratory protection program that meets OSHA's 29 CFR 1910.134 and ANSI Z88.2requirements must be followed whenever workplace conditions warrant a respirator's use.

Skin: The use of gloves impervious to the specific material handled is advised to prevent skincontact, possible irritation, and skin damage. Examples of approved materials are nitrile,or Viton® (see glove manufacturer literature for information on permeability). Dependingon conditions of use, apron and/or arm covers may be necessary.

Eye/Face: Approved eye protection to safeguard against potential eye contact, irritation, orinjury is recommended. Depending on conditions of use, a face shield may be necessary.

Other Protective Equipment: Eye wash and quick-drench shower facilities should beavailable in the work area. Thoroughly clean shoes and wash contaminated clothing before reuse.It is recommended that impervious clothing be worn when skin contact is possible.

Suggestions for the use of specific protective materials are based on readily available publisheddata. Users should check with specific manufacturers to confirm the performance of their products.
