SDS00256 - SODA ASH 58% DENSE
_____________________________________________________________________________________________
Hazardous polymerization
Will not occur.
Conditions to avoid
Hygroscopic (absorbs moisture from the air). Simultaneous exposure to soda ash and lime dusts (CaO). In the
presence of moisture (i.e. perspiration) the two materials combine to form corrosive caustic soda (NaOH) which may
cause burns.
Incompatible materials
Acids. Soda Ash is corrosive to aluminum, lead, and zinc and zinc brasses when in solution and to aluminum when
high humidity is present. Silver nitrate. Magnesium. Fluorine. Lithium. Calcium hypochlorite.
Hazardous decomposition products
Carbon dioxide. Decomposition temperature: >400°C / 752 °F.
Information on likely routes of exposure
Inhalation
Material is irritating to mucous membrane and upper respiratory tract. Exposure can cause coughing, chest pains and
difficulty in breathing.
Eye contact
Causes serious eye damage. Effects may include pain, marked redness and swelling.
Skin contact
Symptoms include redness, swelling, itching and pain.
Ingestion
May cause gastrointestinal irritation, nausea, vomiting and diarrhea.
Information on toxicological effects
Symptoms
Excessive contact may produce "soda ulcers" on hands and perforation of the nasal septum. Sensitivity reactions may
occur from prolonged and repeated exposure.
Numerical measures of toxicity
Acute toxicity
The following values are calculated based on chapter 3.1 of the GHS document .
