TYPES OF HAZARD / EXPOSURE	ACUTE HAZARDS / SYMPTOMS	PREVENTION	FIRST AID / FIRE FIGHTING
FIRE	Not combustible. Gives off irritating or toxic fumes (or gases) in a fire.		In case of fire in the surroundings: all extinguishing agents allowed.
EXPLOSION			In case of fire: keep drums, etc., cool by spraying with water.

EXPOSURE		PREVENT DISPERSION OF DUST! STRICT HYGIENE!
Inhalation	Cough. Shortness of breath. Sore throat.	Avoid inhalation of fine dust and mist. Local exhaust or breathing protection.	Fresh air, rest. Refer for medical attention.
Skin	Redness. Pain.	Protective gloves. Protective clothing.	Rinse skin with plenty of water or shower. Refer for medical attention.
Eyes	Corrosive. Redness. Severe deep burns.	Safety goggles.	First rinse with plenty of water for several minutes (remove contact lenses if easily possible), then take to a doctor.
Ingestion	Abdominal pain. Burning sensation. Nausea. Vomiting.	Do not eat, drink, or smoke during work.	Rinse mouth. Do NOT induce vomiting. Give plenty of water to drink. Refer for medical attention.

ALUMINIUM SULFATE

ICSC: 1191

IMPORTANT DATA

PHYSICAL STATE; APPEARANCE:
ODOURLESS WHITE, LUSTROUS CRYSTALS OR POWDER.

CHEMICAL DANGERS:
The substance decomposes on heating or on burning producing toxic and corrosive fumes including sulfur oxides. The solution in water is a medium strong acid. Reacts with alkalis and attacks many metals in presence of water.

OCCUPATIONAL EXPOSURE LIMITS:
TLV (as Al soluble salt): 2 mg/m^3 (ACGIH 1993-1994).

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 irritates the eyes, the skin and the respiratory tract. Corrosive on ingestion.

PHYSICAL PROPERTIES

Melting point (decomposes): 770°C
Relative density (water = 1): 2.71
Solubility in water: good

ENVIRONMENTAL DATA

This substance may be hazardous to the environment; special attention should be given to fish.

NOTES

Cake alum, pickle alum, filter alum, papermaker's alum and pearl alum are other common names of aluminium sulfate. Occurs in nature as the mineral alunogenite.
