3 - Hazards Identification
SPECIAL INDICATION OF HAZARDS TO HUMANS AND THE ENVIRONMENT
Very toxic by inhalation, in contact with skin and if swallowed.
4 - First Aid Measures
AFTER INHALATION
If inhaled, remove to fresh air. If not breathing give
artificial respiration. If breathing is difficult, give oxygen.
AFTER SKIN CONTACT
In case of skin contact, flush with copious amounts of water for
at least 15 minutes. Remove contaminated clothing and shoes.
Call a physician.
AFTER EYE CONTACT
In case of contact with eyes, flush with copious amounts of
water for at least 15 minutes. Assure adequate flushing by
separating the eyelids with fingers. Call a physician.
AFTER INGESTION
If swallowed, wash out mouth with water provided person is
conscious. Call a physician immediately.

SIGNS AND SYMPTOMS OF EXPOSURE
Tetrodotoxin is among the most toxic substances known to man.
Death can occur within 30 minutes. It is extremely dangerous by
ingestion, inhalation and skin absorption, or if it enters the
bloodstream in any manner. Symptoms of poisoning which include
numbness, tingling of the lips and inner mouth surfaces,
weakness, paralysis of the limbs and chest muscles, and a drop
in blood pressure have been reported within as little as 10
minutes after exposure. To the best of our knowledge, the
chemical, physical, and toxicological properties have not been
thoroughly investigated.
ROUTE OF EXPOSURE
Skin Contact: May cause skin irritation.
Skin Absorption: May be fatal if absorbed through skin.
Eye Contact: May cause eye irritation.
Inhalation: May be fatal if inhaled. Material may be irritating
to mucous membranes and upper respiratory tract.
Ingestion: May be fatal if swallowed.
TARGET ORGAN INFORMATION
Nerves. Skeletal muscle.
12 - Ecological Information
No data available.
13 - Disposal Considerations
SUBSTANCE DISPOSAL
Contact a licensed professional waste disposal service to dispose
of this material. After use, utensils and the toxin solution
should be soaked overnight or boiled for 20 minutes in an excess
amount of 2% sodium hydroxide solution or sodium hypochlorite (1%
available chlorine) solution in a hood or well ventilated area.
Dissolve or mix the material with a combustible solvent and burn
in a chemical incinerator equipped with an afterburner and
scrubber. Observe all federal, state, and local environmental
regulations.
