3. HAZARDS IDENTIFICATION
Isohexanes Page 2 of 6
Emergency Overview
Extremely Flammable Liquid. Eye Irritant. Skin Irritant. Lung Aspiration Hazard.
Potential Acute Health Effects
Eye Contact: Eye Irritant. Direct contact with liquid can be highly irritating. Vapor concentrations up to
5,000 ppm have been reported to be non-irritating.
Skin Contact: Skin Irritant. Prolonged contact with liquid may cause blistering several hours after
contact. Repeated or prolonged contact may defat the skin, resulting in inflammation.
Inhalation: Overexposure may cause dizziness, headache, excitation, drowsiness, loss of
coordination, sensation, consciousness and possibly death.
Ingestion: If swallowed, may be aspirated resulting in inflammation and possible fluid accumulation in
the lungs. Can cause gastrointestinal irritation, nausea and vomiting.
Aggravated Medical Skin Disorders.
Conditions:
4. FIRST AID MEASURES
Eye Contact: Immediately flush eyes with running water for at least 15 minutes. If irritation or adverse
symptoms develop, seek medical attention.
Skin Contact: Immediately 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 illness or adverse symptoms develop, seek 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: -20F (-29C)
FP Method: TCC, ASTM D56
Ignition Temperature: Unknown
Flammable Limits (% by Volume in Air)
Lower Explosive Limit - 1.0
Upper Explosive Limit - 7.0
Fire Extinguishing Media: Carbon Dioxide, Dry Chemicals, Foam
Fire Fighting Procedures: Evacuate area and fight fire from a safe distance. Shut off source, if possible. Use
NIOSH approved self-contained breathing apparatus and other protective
equipment and/or garments described in Section 8 if conditions warrant. 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 area and/or spread along ground away from
handling site. Flashback along vapor trail may occur.

6. ACCIDENTAL RELEASE MEASURES
Eliminate all ignition sources (no smoking, flares, spark or flames in immediate area). All equipment used when
handling the product must be grounded. Do not touch or walk through spilled material. Stop leak if possible
without risk. Prevent entry into waterways, sewers, basements or confined areas. A vapor suppressing foam may
be used to reduce vapors. Absorb or cover with dry earth, sand or other non-combustible material and transfer to
containers. Use clean non-sparking tools to collect absorbed material.
7. HANDLING AND STORAGE
DO NOT get in eyes, on skin, or on clothing. Avoid breathing vapors, 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: If splash hazards are present use chemical goggles and a face shield.
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 air-
purifying 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.) This material is a skin irritant. Use additional protective garments
to prevent skin contact based on use. )
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:
2,3-Dimethylbutane produced kidney damage in male rats after 28 days of daily oral administration of 500 or
2,000 mg/kg. No comparable kidney injury has been reported in humans.
2-Methylpentane did not produce kidney damage in male rats after 28 days of daily oral administration of 500
mg/kg.
Repeat inhalation exposure (90 days) to 1,500 ppm 2-methylpentane in male rats resulted in no peripheral
nervous system toxicity.
Repeat inhalation exposure (90 days) to 1,500 ppm 3-methylpentane in male rats resulted in no peripheral
nervous system toxicity.
