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 |

| EXPOSURE |
|
PREVENT DISPERSION OF DUST!
|
|
| Inhalation |
Cough.
|
Avoid inhalation of fine dust and mist. Local exhaust or breathing protection.
|
Fresh air, rest.
|
| Skin |
|
Protective gloves.
|
Rinse skin with plenty of water or shower.
|
| Eyes |
|
Safety spectacles.

|
| SPILLAGE DISPOSAL | PACKAGING & LABELLING |
Sweep spilled substance into covered containers; if appropriate, moisten first to prevent dusting (extra personal protection: P1 filter respirator for inert particles).
|
|
| EMERGENCY RESPONSE | STORAGE |
|
Separated from acids.
|
| IMPORTANT DATA | |
|
PHYSICAL STATE; APPEARANCE:
WHITE POWDER. CHEMICAL DANGERS: The substance decomposes on heating producing acrid smoke and irritating fumes. Reacts with acids liberating carbon dioxide gas. OCCUPATIONAL EXPOSURE LIMITS: TLV: ppm; 10 mg/m 3 (as TWA) (ACGIH 1995-1996). |
ROUTES OF EXPOSURE:
The substance can be absorbed into the body by inhalation of its aerosol. INHALATION RISK: Evaporation at 20°C is negligible; a nuisance-causing concentration of airborne particles can, however, be reached quickly on spraying or when dispersed, especially if powdered. EFFECTS OF LONG-TERM OR REPEATED EXPOSURE: The substance may have effects on the lungs if the magnesite contains more than 1% crystalline silica. |
| PHYSICAL PROPERTIES | |
|
Melting point (decomposes): 350°C
Relative density (water = 1): 2.95 Solubility in water, g/100 ml: none |

|
|
| NOTES | |
|
If magnesite contains >1% crystalline silica, also consult ICSC # 0808.
