WHITE
CRYSTALLINE POWDER
Physical Dangers:
Chemical Dangers:
The substance decomposes
on warming above 60°C
producing
toxic fumes
including
sodium oxide
and
on contact with water producing boric acid and hydrogen peroxide.
The substance is a strong oxidant and reacts with combustible and reducing materials.
The solution in water is a weak base.
Occupational Exposure Limits:
TLV not established.
MAK not established.
|
Routes of Exposure:
The substance can be absorbed into the body
by inhalation
and
by ingestion.
Inhalation Risk:
Evaporation at 20°C is negligible; a harmful concentration of airborne particles can, however, be reached quickly when dispersed, especially if powdered.
Effects of Short-Term Exposure:
The substance
is irritating to
the eyes
and
the respiratory tract
.
Effects of Long-Term or Repeated Exposure:
|
|
Physical Properties
|
Melting point (decomposes): about 60-65.5°C
|
