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.
|
| SPILLAGE DISPOSAL | PACKAGING & LABELLING |
Sweep spilled substance into containers; if appropriate, moisten first to prevent dusting (extra personal protection: P2 filter respirator for harmful particles).
|
UN Hazard Class
UN Pack Group |
| EMERGENCY RESPONSE | STORAGE |
|
Separated from strong bases. Dry.
|
| 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): ppm; 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.
