TYPES OF HAZARD / EXPOSURE	ACUTE HAZARDS / SYMPTOMS	PREVENTION	FIRST AID / FIRE FIGHTING
FIRE	Not combustible.		In case of fire in the surroundings: use appropriate extinguishing media.
EXPLOSION

EXPOSURE
Inhalation	Cough. Sore throat.	Local exhaust or breathing protection.	Fresh air, rest.
Skin	Redness.	Protective gloves.	Remove contaminated clothes. Rinse and then wash skin with water and soap.
Eyes	Redness. Pain.	Safety goggles	Rinse with plenty of water (remove contact lenses if easily possible).
Ingestion		Do not eat, drink, or smoke during work.	Rinse mouth.

SPILLAGE DISPOSAL	PACKAGING & LABELLING
Personal protection: particulate filter adapted to the airborne concentration of the substance. Sweep spilled substance into sealable containers; if appropriate, moisten first to prevent dusting.

EMERGENCY RESPONSE	SAFE STORAGE

IMPORTANT DATA
Physical State; Appearance WHITE CRYSTALLINE POWDER Chemical dangers The substance decomposes on heating (at 965°C), producing molybdate oxide fumes. Occupational exposure limits TLV: Mo, insoluble compounds, respirable fraction 3 mg/m³ as TWA TLV: Mo, insoluble compounds, inhalable fraction 10 mg/m³ as TWA (ACGIH 2006). MAK: IIb (not established but data is available) (DFG 2006).	Inhalation risk A nuisance-causing concentration of airborne particles can be reached quickly when dispersed, especially if powdered. Effects of short-term exposure May cause mechanical irritation to the eyes, the skin, and the respiratory tract.

PHYSICAL PROPERTIES	ENVIRONMENTAL DATA
Decomposes at 965 °C Density: 4.4 g/cm³ Solubility in water, g/100 ml at 25°C: (very poor) 0.005
