TYPES OF HAZARD / EXPOSURE	ACUTE HAZARDS / SYMPTOMS	PREVENTION	FIRST AID / FIRE FIGHTING
FIRE	Combustible under specific conditions. Gives off irritating or toxic fumes (or gases) in a fire.	NO open flames. NO contact with oxidants, halogens, acid(s).	water spray, foam, powder, carbon dioxide
EXPLOSION	Finely dispersed particles form explosive mixtures in air. Risk of fire and explosion on contact with acid(s) halogens and.	Prevent deposition of dust; closed system, dust explosion-proof electrical equipment and lighting.

EXPOSURE		PREVENT DISPERSION OF DUST!
Inhalation	Cough. (See Ingestion).	Local exhaust or breathing protection.	Fresh air, rest.
Skin		Protective gloves.	Remove contaminated clothes. Rinse and then wash skin with water and soap.
Eyes	Redness. Pain.	Safety goggles, or eye protection in combination with breathing protection if powder.	First rinse with plenty of water for several minutes (remove contact lenses if easily possible), then take to a doctor.
Ingestion	Abdominal pain. Vomiting. Diarrhoea.	Do not eat, drink, or smoke during work.	Rinse mouth. Refer for medical attention if you feel unwell.

SPILLAGE DISPOSAL	PACKAGING & LABELLING
Personal protection: P2 filter respirator for harmful particles. Sweep spilled substance into sealable containers; if appropriate, moisten first to prevent dusting.	UN classification UN Hazard Class: 6.1 UN Pack Group: III	Do not transport with food and feedstuffs.

EMERGENCY RESPONSE	SAFE STORAGE
Transport Emergency Card: TEC (R)-61GT5-III	Separated from oxidants, acids, halogens, food and feedstuffs.

IMPORTANT DATA

Physical State; Appearance
SILVER-WHITE, LUSTROUS, HARD, BRITTLE LUMPS OR DARK GRAY POWDER

Physical dangers
Dust explosion possible if in powder or granular form, mixed with air.

Chemical dangers
On combustion, forms toxic fumes (antimony oxides; see ICSC 0012). Reacts violently with oxidants, acids, halogens and powdered metals, causing fire and explosion hazard. On contact with acids may emit toxic gas (stibine; see ICSC 0776).

Occupational exposure limits
TLV: 0.5 mg/m³ as TWA (ACGIH 2006).
MAK: Carcinogen category: 2; Germ cell mutagen group: 3B (DFG 2006).

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

Inhalation risk
A harmful concentration of airborne particles can be reached quickly when dispersed.

Effects of short-term exposure
May cause mechanical irritation to the eyes. Exposure by inhalation and by ingestion could cause gastrointestinal irritation.

Effects of long-term or repeated exposure
Repeated or prolonged contact with skin may cause dermatitis, especially when exposed to fumes. The substance may have effects on the lungs, resulting in pneumoconiosis.

PHYSICAL PROPERTIES	ENVIRONMENTAL DATA
Boiling point: 1635 °C Melting point: 630 °C Density: 6.7 g/cm³ Solubility in water: none

NOTES

Other boiling points: 1325°C, 1440°C, 1587 °C, 1750°C.
The recommendations on this card apply only to metallic antimony.
