ABC of Safety in the Biological Sciences
TRYPSIN
SYNONYMS
None known.
GENERAL PRECAUTIONS
Avoid skin and eye contact.
Avoid inhalation.
Wash hands thoroughly after handling.
CHARACTERISTICS
White to cream crystals or powder, no odour.
HEALTH HAZARD DATA
This substance is a respiratory tract and eye irritant and may
cause allergic skin reactions. It is generally regarded as being
of very low toxicity. Contact of the dry powder with surface
lesions may cause a burning sensation. Trypsin should not be
handled by persons who suffer from asthma.
TREATMENTS
Skin immediately wash the affected area with large amounts of
water until all evidence of the chemical has been removed
(approximately 15 minutes). If an allergic reaction develops
seek medical immediate attention.
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 persists immediate
medical attention.
Inhalation remove from the area of exposure to fresh air. If
discomfort persists seek medical attention.
Ingestion wash out the mouth with water and give plenty of
water to drink. If discomfort persists seek medical advice.
INCOMPATIBILITY
Trypsin contains about 85% lactose as a diluent. Lactose can
react violently with oxidising agents.
STORAGE
Store at 4°C in airtight containers.
HANDLING
Trypsin should not be handled by persons who suffer from asthma.
Wear protective clothing to avoid skin or eye contact or
inhalation. A long sleeved laboratory coat or gown, rubber
gloves, safety goggles and a face mask as a minimum standard.
DISPOSAL
WEAR:
Heavy leather gloves and safety glasses.
DISPOSAL:
Materials should be properly packed for safe handling and placed
in a prescribed site for daily collection. Burning can be done
in an open or closed incinerator equipped with an afterburner.
