Effects of Overexposure
Acute:
Inhalation: Vapors or mist may cause irritation of the nose and throat. Inhalation may cause dizziness,
drowsiness, euphoria, loss of coordination, disorientation, headache, nausea, and vomiting.
In poorly ventilated areas or confined spaces, unconsciousness and asphyxiation may result.
Prolonged or repeated overexposure may result in the absorption of potentially harmful
amounts of material.
Dust may cause irritation of the nose and throat. Overexposure to high concentrations of
dust may cause respiratory irritation, experienced as coughing and difficulty breathing.
Skin:
Eyes:
Ingestion:
Sensitization Properties:
Product may contain residual amounts of dust or small particulates that may cause skin
irritation or abrasion experienced as local redness with possible mild discomfort.
Vapor may cause irritation, experienced as discomfort, with excess tear production and
blinking, and seen as excess redness of the eye. Product may contain residual amounts of
dust or small particulates which may cause eye irritation or abrasion experienced as mild
discomfort and slight excess redness of the eye.
If more than several mouthfuls are swallowed, abdominal discomfort, nausea, and diarrhea
may occur.

If more than several mouthfuls of this material are swallowed, give two glasses of water (16 oz.). Get medical attention.
Eyes:

Inhalation:
Ingestion:
Flush eyes with plenty of water for several minutes. Remove larger particulates from the eye as one would any foreign object.
Get medical attention if eye irritation persists or particulates are difficult to remove from the eye.
Wash skin with plenty of soap and water for several minutes. Get medical attention if skin irritation develops or persists.
If inhaled, remove to fresh air. If not breathing, clear person's airway and give artificial respiration. If breathing is difficult,
qualified medical personnel may administer oxygen. Get medical attention immediately.

4. FIRST AID MEASURES
Other Instructions:
None.
Recommended Fire Extinguishing Agents And Special Procedures:
Water may be ineffective on flames but should be used to cool fire-exposed containers and provide protection for persons
attempting to stop the leak. Use water spray, dry chemical, foam or carbon dioxide to extinguish flames.
Wear full protective clothing and positive pressure breathing apparatus.

5. FIRE-FIGHTING MEASURES
Special Protective Equipment for Firefighters:
Flash Point (degrees C):
Ignition Temperature - AIT (degrees C):
260 (500 F) for Pentane
471 (880 F) by ASTM D-1929 Expanded polystyrene
-40 (-40 F) CC for Pentane
Flammable Limits % (Lower-Upper):
Lower: 1.5 for Pentane
Upper: 7.8 for Pentane
Unusual or Explosive Hazards:
Danger! Extremely flammable materials may release vapors that travel long distances, ignite, and flash back. Containers may
explode in a fire. Do not expose to heat, sparks, flame, static, or other sources of ignition. When handling, use non-sparking
tool, ground and bond all containers.
Explosive air-vapor mixtures may form. Fire gives off dense black smoke and acid gasses. Electrostatic discharge can be a
source of ignition due to accumulated pentane vapors exceeding the L.E.L. (lower explosive limit) of 1.5% (15,000 ppm).
Pentane vapors may be emitted from newly opened containers or when the product is heated. If ignited, there could be a very
high rate of flame propagation.
"NO SMOKING - NO MATCHES - NO LIGHTERS - NO WELDING" rules should be enforced.

6. ACCIDENTAL RELEASE MEASURES (Transportation Spills: CHEMTREC (800)424-9300)
Procedures in Case of Accidental Release, Breakage or Leakage:
Avoid the generation of dust clouds. Place in appropriate containers for disposal or recycle. Avoid breathing dust. Pressure
demand air supplied respirators should always be worn when the airborne concentration of the contaminant or oxygen is
unknown. Otherwise, wear respiratory protection and other personal protective equipment as appropriate for the potential
exposure hazard. Wear gloves, goggles, and protective clothing to avoid contact with eyes, skin, or clothing. Use vacuuming
or sweeping compound for clean-up. Do not dry sweep or use methods which increase dusting. Prevent entry into sewers and
waterways.
Storage:
Ground and bond shipping container, transfer line, and receiving container. Keep away from heat, sparks, flame, and other
sources of ignition.
Use spark-proof tools. Material may be at elevated temperatures and/or pressures. Exercise care when opening bleeders
and sampling ports.
Handling:

7. HANDLING AND STORAGE
Precautions to be Taken in
Respiratory Protection:
Skin Protection:
Use explosion-proof equipment to maintain adequate ventilation to meet occupational exposure limits, if applicable (see
below), prevent accumulation of explosive air-gas mixtures, and avoid significant oxygen displacement. Oxygen levels should
be at least 19.5% in confined spaces or other work areas (OSHA value).
Workers should wash exposed skin several times daily with soap and water. Soiled work clothing should be laundered or
dry-cleaned.
Eye/Face Protection:
Ventilation:
Avoid eye contact. Chemical type goggles should be worn. Do not wear contact lenses.
None established for product; refer to Section 2 for component exposure limits.

8. EXPOSURE CONTROLS/PERSONAL PROTECTION
Exposure Limit for the Total Product:
Airborne concentrations should be kept to lowest levels possible. If vapor, mist or dust is generated and the occupational
exposure limit of the product, or any component of the product, is exceeded, use appropriate NIOSH or MSHA approved air
purifying or air supplied respirator after determining the airborne concentration of the contaminant. Air supplied respirators
should always be worn when airborne concentration of the contaminant or oxygen content is unknown.

Product may contain dust or particulates that may cause eye irritation or abrasion.
This product may contain residual styrene. Typical concentrations are less than 0.1%. Please refer to product-specific
purchasing specifications for information on residual styrene content of this product.
Chronic (lifetime) exposure to styrene resulted in bronchoalveolar (lung) tumors in mice, but not in rats. The relevance of these
cell-type specific mouse lung tumors to humans is not known. Nasal effects were also observed in these rats and mice
exposed to styrene. In subchronic exposure studies, repeated exposures of female mice to styrene resulted in liver toxicity,
however, this effect was not observed in rats.
