TYPES OF HAZARD / EXPOSURE	ACUTE HAZARDS / SYMPTOMS	PREVENTION	FIRST AID / FIRE FIGHTING
FIRE	Combustible. Gives off irritating or toxic fumes (or gases) in a fire.	NO open flames.	Powder, water spray, foam, carbon dioxide.
EXPLOSION

EXPOSURE		PREVENT DISPERSION OF DUST!
Inhalation	Cough. Sore throat (see Ingestion).	Local exhaust or breathing protection.	Fresh air, rest.
Skin	Redness. Burning sensation. Pain. Blisters.	Protective gloves. Protective clothing.	Remove contaminated clothes. Rinse and then wash skin with water and soap.
Eyes	Redness. Pain. Severe deep burns.	Safety goggles, or eye protection in combination with breathing protection.	First rinse with plenty of water for several minutes (remove contact lenses if easily possible), then take to a doctor.
Ingestion	Abdominal pain. Convulsions. Drowsiness. Dullness. Shock or collapse. Vomiting.	Do not eat, drink, or smoke during work.	Rinse mouth. Give plenty of water to drink. Rest. Refer for medical attention.

AMMONIUM OXALATE

ICSC: 1036

IMPORTANT DATA

PHYSICAL STATE; APPEARANCE:
ODOURLESS, COLOURLESS, CRYSTALLINE POWDER.

CHEMICAL DANGERS:
The substance decomposes on heating or on burning producing toxic and corrosive fumes including ammonia and nitrogen oxides. Reacts with oxidants.

OCCUPATIONAL EXPOSURE LIMITS:
TLV not established.

ROUTES OF EXPOSURE:
The substance can be absorbed into the body by ingestion.

INHALATION RISK:
Evaporation at 20°C is negligible; a nuisance-causing concentration of airborne particles can, however, be reached quickly.

EFFECTS OF SHORT-TERM EXPOSURE:
The substance irritates the eyes, the skin and the respiratory tract. The substance may cause effects on the central nervous system and kidneys , resulting in impaired functions.

EFFECTS OF LONG-TERM OR REPEATED EXPOSURE:
The substance may have effects on the kidneys.

PHYSICAL PROPERTIES

Decomposes below melting point at see Notes
Relative density (water = 1): 1.50
Solubility in water: moderate

ENVIRONMENTAL DATA

NOTES

The physical properties are those of the monohydrate. Temperature of decomposition unknown in literature.
