TIN(II) OXIDE ICSC: 0956
IMPORTANT DATA
PHYSICAL STATE; APPEARANCE:
BLUE TO BLACK CRYSTALLINE POWDER

CHEMICAL DANGERS:
On heating at 300°C in air, oxidation to stannic oxide proceeds incandescently.

OCCUPATIONAL EXPOSURE LIMITS:
TLV: (as Sn, Oxide and inorganic compounds, except tin hydride) 2 mg/m³ as TWA; (ACGIH 2004).
EU OEL: (Tin inorganic compounds, as Sn) 2 mg/m³ as TWA; (EU 2004).
 		INHALATION RISK:
A harmful concentration of airborne particles can be reached quickly when dispersed, especially if powdered.

EFFECTS OF SHORT-TERM EXPOSURE:
May cause mechanical irritation to the respiratory tract.

EFFECTS OF LONG-TERM OR REPEATED EXPOSURE:
Lungs may be affected by repeated or prolonged exposure to dust particles, resulting in a benign pneumoconiosis (stannosis).
PHYSICAL PROPERTIES
Density: 6.45 g/cm³
Solubility in water: none
ENVIRONMENTAL DATA
Bioaccumulation of this chemical may occur in crustacea and in fish.
