SECTION 4 - Fire and Explosion Hazard Data
Flash Point : 357 鈩?
Flammability Limits in Air ( For Pentane ) : Lower 锛? 1.5 % ; Upper 锛? 7.8 %
Special Fire Fighting Instructions : Use approved self-contained breathing apparatus
respirator and approved personal protective clothing.
Extinguish Media : Water fog, Carbon Dioxide foam, and Dry Chemicals
Auto Ignition Temperature : 471 鈩?
Unusual Fire and Explosion Hazards
: Fire gives off dense black smoke and acid gases. Electrostatic discharge can be a source
of ignition to accumulated pentane vapors exceeding the L.E.L. 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.
SECTION 5 - Reactive Data
Stability ( Conditions to Avoid ) : Stable product avoid fires and high temperature
Hazardous Decomposition Product : Carbon monoxide, Acid gases, Water, Carbon dioxide
Incompatibility ( Materials to Avoid ) : Hydrocarbons, Esters, Insecticides,
Amines and Aldehydes
Hazardous Polymerization Product : None
SECTION 6 - Health Hazardous Data
Principal Health Hazards & Signs and Symptoms of Exposure :
General : Normal handling would never expose operating personnel to pentane levels
above published health levels.
Eye Contact : None
Inhalation : Normal handling would never exeed safe pentane health limits.
Very high levels could produce a narcotic effect. Studies have shown that
exposures to pentane for 10 minutes at 5,000 ppm produced no syptoms.
Skin Contact : None
Ingestion : Biologically inert. Extremely unlikely route of entry.
Systemic & Other Effects : None
Medical Conditions Aggravated : None
Exposure Limits ( For Pentanes ) : PEL (OSHA) : 1,000 ppm 8-hour TWA
TLV (ACGIH) : 600 ppm TWA, 1,800 mg/m
Safety Precautions : Use positive ventilation. Do not smoke or eat in process area.
Avoid spark producing equipment, material handling devices,
open flames, and high temperatures.
Provide and assure proper electrostatic bonding and grounding of
process handling equipment.

Toxicity Data : ORAL : Pentane oral acute inhalation LC50 is greater than 200mg/l.
INHALATION : LC50 锛? 130,000 ppm
DEMAL : None
Carcinogenicity : None
SECTION 7 - Preventive Measures
Personal Protective Equipment :
Respiratory Protection : Use approved air purifying respirators with organic vapor
cartridge for exposure above health limits.
Skin Protection : None under normal conditions.
Eye Protection : ANSI - approved safety glasses with side shields.
General Control Measures : Use positive ventilation and provide electrostatic bonding and
grounding of equipment.
Environmental Hazards : Sewer/waterway obstruction
Fish may eat beads and obstruct their digestive tract.
Repotable Quantity : None (not regulated)
Disposal Method : Recycle, incinerate, or land fill per local and state regulations.
Spill, Leak, or Release Procedures : Stop leak, contain spill, obstruct exit sewers,
waterways, and sources of ignition.
Collect into non-conducting containers.
SECTION 8 - First Aid Measures
Eyes : Irrigate with water to wash out any particles.
Inhalation : ( Pentane vapors ) : Remove to fresh air. Provide CPR if breathing has
stopped. Notify medical personnel.
Ingestion : Notify medical personnel.
Skin : Wash with soap and water to remove particles.
General Advice : Use positive ventilation. Do not smoke or eat in process area.
We hereby certify that the above statements are true and correct
in every respect. If the statements are not true, all responsibility
will belong to CHEIL.
