ABC of Safety in the Biological Sciences
SODIUM IODATE (NaIO3)
SYNONYMS
None known.
GENERAL PRECAUTIONS
Avoid eye contact.
Avoid inhalation or ingestion of the powder.
Keep away from heat.
Keep away from combustible substances.
Keep away from finely divided metals.
Wash hands thoroughly after handling.
CHARACTERISTICS
White crystals.
HEALTH HAZARD DATA
Contact with a combustible material can cause fire. It is an eye
and respiratory tract irritant and is mildly toxic.
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 discomfort develops seek medical
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 seek medical
attention.
Inhalation remove from the area of exposure to fresh air. Keep
warm and allow to rest. If irritation persists seek medical
attention.
Ingestion wash out the mouth thoroughly with water and give
water to drink. Seek immediate medical attention.
INCOMPATIBILITY
Heating produces toxic fumes of iodine compounds. Sodium iodate
can react vigorously with reducing materials and explosively
with finely divided metals, carbon, phosphorus, sulphur, metal
hydrides, many sulphides, thiocyanates, cyanides and impure
manganese dioxide.
STORAGE
Store in a cool, dry atmosphere away from heat, combustible and
incompatible substances.
HANDLING
Wear protective clothing to avoid 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:
Rubber gloves, safety glasses and laboratory coat.
SPILLS:
Solid: collect in a beaker, dissolve in a large amount of water.
Add soda ash, mix and neutralise with 6M hydrochloric acid and
discharge to sewer with large excess of water.
Solution: cover with soda ash, mix and scoop into a beaker of
water. Neutralise with 6M hydrochloric acid and discharge to
sewer with a large excess of water. If a spill contains a
fluoride, add slaked lime in addition to the above treatment.
PACKAGE LOTS:
Add slowly to a large container of water. Stir in a slight
excess of soda ash. If fluoride is present add slaked lime. Let
stand for 24 hours. Decant or siphon into another container and
neutralise with 6M hydrochloric acid. Discharge to sewer with a
large excess of water. The sludge may be added to land fill.
