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: use appropriate extinguishing media.
EXPLOSION

EXPOSURE		PREVENT DISPERSION OF DUST! AVOID EXPOSURE OF (PREGNANT) WOMEN!
Inhalation	Cough.	Ventilation, local exhaust, or breathing protection.	Fresh air, rest. Refer for medical attention.
Skin		Protective gloves.	Remove contaminated clothes. Rinse and then wash skin with water and soap.
Eyes		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

SPILLAGE DISPOSAL	PACKAGING & LABELLING
Personal protection: P2 filter respirator for harmful particles. Sweep spilled substance into containers. Carefully collect remainder, then remove to safe place.

EMERGENCY RESPONSE	SAFE STORAGE

IMPORTANT DATA

Physical State; Appearance
BROWN TO BLACK CRYSTALLINE POWDER

Occupational exposure limits
TLV: as Mn 0.2 mg/m³ as TWA; (ACGIH 2006).
MAK: as Mn (Inhalable fraction) 0.5 mg/m³; Pregnancy risk group: C; (DFG 2005).

Routes of exposure
The substance can be absorbed into the body by inhalation of its aerosol and by ingestion.

Inhalation risk
Evaporation at 20°C is negligible; a harmful concentration of airborne particles can, however, be reached quickly when dispersed.

Effects of short-term exposure
May cause mechanical irritation.

Effects of long-term or repeated exposure
The substance may have effects on the lungs and central nervous system, resulting in increased susceptibility to bronchitis, pneumonitis and neurologic, neuropsychiatric disorders (manganism). Animal tests show that this substance possibly causes toxicity to human reproduction or development.

PHYSICAL PROPERTIES	ENVIRONMENTAL DATA
Melting point: 1564°C Density: 4.8 g/cm³ Solubility in water, g/100 ml: none

NOTES

Depending on the degree of exposure, periodic medical examination is suggested.
Occurs in nature as the mineral Hausmannite.
