3. HAZARDS IDENTIFICATION Emergency Overview

Hexane(S)

Page 2 of 6

Extremely Flammable Liquid. Lung Aspiration Hazard. Nerve Toxin.

Potential Acute Health Effects Eye Contact:

May cause mild irritation.

Skin Contact:

May cause mild irritation. Can be absorbed through skin in harmful amounts.

Inhalation:

Vapors may be mildly irritating to lungs. Overexposure may result in dizziness, headache, excitation, central nervous system depression.

Ingestion:

May cause effects similar to those of inhalation and gastrointestinal irritation. If swallowed, may be aspirated resulting in inflammation and possible fluid accumulation in the lungs.

Aggravated Medical Conditions:

No Known Applicable Information

4. FIRST AID MEASURES Eye Contact:

Flush eyes with running water for at least 15 minutes. If irritation or adverse symptoms develop, seek medical attention.

Skin Contact:

Wash skin with soap and water for at least 15 minutes. If irritation or adverse symptoms develop, seek medical attention.

Inhalation:

Remove from exposure. If breathing is difficult, give oxygen. If breathing ceases, administer artificial respiration followed by oxygen. Seek immediate medical attention.

Ingestion:

DO NOT induce vomiting. Seek immediate medical attention.

Notes To Physician: Gastric lavage using a cuffed endotracheal tube may be performed at your discretion.

5. FIRE FIGHTING MEASURES Flash Point: FP Method: Ignition Temperature:

-15 F (-26C) TCC, ASTM D56 437 (225)

Flammable Limits (% by Volume in Air) Lower Explosive Limit 1.2 Upper Explosive Limit 7.7 Fire Extinguishing Media:

Carbon Dioxide, Dry Chemicals, Foam

Fire Fighting Procedures:

Evacuate area and fight fire from a safe distance. Use NIOSH approved selfcontained breathing apparatus and other protective equipment and/or garments described in Section 8 if conditions warrant. Shut off source, if possible. Use water spray to cool nearby containers and structures exposed to fire. Do not spray water directly on fire - product will float and could be reignited on surface of water.

Fire and explosion hazards: Carbon oxides formed when burned. Highly flammable vapors which are heavier than air may accumulate in low areas and/or spread along ground away from handling site. Flash back along vapor trail is possible.

6. ACCIDENTAL RELEASE MEASURES

Hexane(S)

Page 3 of 6

Evacuate area of all unnecessary personnel. Wear protective equipment and/or garments described in Section 8 exposure conditions warrant. Protect from ignition. Keep out of water sources and sewers. Absorb in a dry, inert material (sand, clay, etc.). Transfer to disposal drums using non-sparking equipment.

7. HANDLING AND STORAGE DO NOT get in eyes, on skin, or on clothing. DO NOT breathe vapor, mist, fume or dust. DO NOT swallow. May be aspirated into lungs. Wear protective equipment and/or garments described in Section 8 if exposure conditions warrant. Wash thoroughly after handling. Immediately remove and launder contaminated clothing before reuse. Use only with adequate ventilation. Keep away from heat, sparks, and flame. Store in well-ventilated area. Store in tightly closed container. Bond and ground during transfer.

8. EXPOSURE CONTROLS/PERSONAL PROTECTION Eye Protection:

Use safety glasses with side shields.

Respiratory Protection:

For concentrations exceeding an applicable exposure limit, use NIOSH approved air purifying respirator equipped with organic vapor cartridges. Air purifying respirators should NOT be used in: - Situations that exceed the maximum use concentrations of the respirator or airpurifying element established by regulatory standards. - Atmospheres containing less than 19.5 percent oxygen. - Atmospheres immediately dangerous to life or health (IDLH) When entering or exiting from areas where the exposure concentration is unknown or if conditions immediately dangerous to life or health (IDLH) exist, use a NIOSH approved self-contained breathing apparatus (SCBA) or equivalent operated in a pressure demand or other positive pressure mode.

Skin Protection:

Use gloves resistant to the material(s) contained in this product. (Nitrile, Polyvinyl Alcohol or Viton.)

Ventilation:

Use adequate ventilation to control concentrations below applicable exposure limits.

Other Personal Protection: Personal protection information shown in Section 8 is based upon general information as to normal uses and conditions. Where special or unusual uses or conditions exist, it is suggested that the expert assistance of an industrial hygienist or other qualified professional be sought. Exposure Limits:

See Section 2 (Composition/Information on Ingredients).

11. TOXICOLOGICAL INFORMATION Subchronic and Chronic Effects: Chronic high levels n-hexane exposure damages the nervous system initially producing a lack of feeling in the extremities and possibly progressing to a more severe nerve damage. Excessive inhalation (a single continuous 24-hr. exposure) to 5,000 ppm n-hexane vapor has produced testicular damage in rats. Prolonged inhalation exposure (16-24 hr/day for one to two months) to 1,000 ppm n-hexane vapor also has produced testicular damage in rats. Mice exposed for prolonged periods and to the same or higher levels of n-hexane (10,000 ppm) did not exhibit any testicular effects. Methylcyclopentane orally administered at daily dosages of 0.5 or 2.0 g/kg, five days/week for four weeks caused no effects of toxicological significance in laboratory rats. Methylcyclopentane did not produce kidney damage in male rats after 28 days of daily oral administration of 500 or 2,000 mg/kg.

Other Health Effects: A Toxicity Study Summary for n-Hexane is available upon request.

Acute Data: Hexane: Dermal LD50 > 2,000 mg/kg (Rabbit); LC50 > 3,367 ppm (4-hr., Rat); Oral LD50 > 5,000 mg/kg (Rat). Methylcyclopentane: No data available.

12. ECOLOGICAL INFORMATION No data at this time.

13. DISPOSAL CONSIDERATIONS Disposal should be made in accordance with federal, state and local regulations.
