ABC of Safety in the Biological Sciences
ISO-PENTANE (CH3)2=CH2CH3
SYNONYMS
2-Methylbutane, ethyldimethylmethane.
GENERAL PRECAUTIONS
Keep away from eyes and skin.
Avoid inhalation and ingestion.
Keep away from heat or naked flames.
Earth containers before pouring.
CHARACTERISTICS
Colourless liquid with characteristic odour.
HEALTH HAZARD DATA
Highly flammable liquid, the vapours are heavier than air and
can travel along the ground for a considerable distance to a
source of ignition and flash back. Static electricity can be
produced when pouring from a large container. Toxicity data is
not available. Eye and skin irritant. Causes redness and pain to
eyes. Inhalation increases the risk of developing pneumonia,
high concentrations can cause unconsciousness. Is a central
nervous system depressant. The use of alcoholic beverages
enhances the toxic effect of iso-pentane. Ingestion may cause
abdominal pain and nausea.
TREATMENTS
Skin - Immediately wash the affected area with soap or mild
detergent and large amounts of water until all evidence of the
chemical has been removed (approximately 15 minutes). If
irritation persists or dermatitis develops seek medical advice.
Remove contaminated clothing and shoes and decontaminate before
re-use.
Eyes - Immediately wash the affected eye with large amounts of
water until all evidence of the chemical has been removed
(approximately 15 minutes). If irritation or pain persists seek
immediate medical attention.
Inhalation - Remove from the area of exposure to fresh air. Keep
warm and allow to rest. Seek medical advice.
Ingestion - Never give anything by mouth if the victim is losing
consciousness, is unconscious or convulsing. Rinse the mouth
thoroughly with water. Do not induce vomiting. Seek immediate
medical attention.
INCOMPATIBILITY
No data available.
STORAGE
Store in a cool, dry atmosphere away from heat and incompatible
substances.
HANDLING
Wear protective clothing. A long sleeved laboratory coat or gown
with elasticised wrist bands, rubber gloves and safety goggles
as a minimum standard.
DISPOSAL
For disposal of small amounts absorb on a filter paper or
absorbent paper and burn in a fume hood. For large amounts use
high temperature incineration.
ENVIRONMENT:
No data available.
