  ACUTE HAZARDS PREVENTION FIRE FIGHTING
FIRE & EXPLOSION Combustible under specific conditions. Gives off irritating or toxic fumes (or gases) in a fire.  Finely dispersed particles form explosive mixtures in air. Risk of fire and explosion on contact with acids or halogens.  NO open flames. NO contact with oxidizing agents, halogens or acids.  Closed system, dust explosion-proof electrical equipment and lighting. Prevent deposition of dust.  Use water spray, foam, powder, carbon dioxide.   

 PREVENT DISPERSION OF DUST!  
  SYMPTOMS ACUTE HAZARDS FIRST AID
Inhalation Cough. See Ingestion.  Use 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.  Wear 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 refer for medical attention. 
Ingestion Abdominal pain. Vomiting. Diarrhoea.  Do not eat, drink, or smoke during work.  Rinse mouth. Refer for medical attention . 

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

According to UN GHS Criteria

 

Transportation
UN Classification
UN Hazard Class: 6.1; UN Pack Group: III 

STORAGE
Separated from oxidants, acids, halogens and food and feedstuffs. 
PACKAGING
Do not transport with food and feedstuffs. 
ANTIMONY ICSC: 0775
PHYSICAL & CHEMICAL INFORMATION

Physical State; Appearance
SILVER-WHITE LUSTROUS HARD BRITTLE LUMPS OR DARK GREY POWDER. 

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

Chemical dangers
On combustion, forms toxic fumes of antimony oxides (see ICSC 0012). Reacts violently with oxidants, acids, halogens and powdered metals. This generates fire and explosion hazard. Contact with acids may generate toxic gas (stibine - see ICSC 0776). 

Formula: Sb
Atomic mass: 121.8
Boiling point: 1635 °C
Melting point: 630 °C

EXPOSURE & HEALTH EFFECTS

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

Effects of short-term exposure
May cause mechanical irritation to the eyes. 

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

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


Occupational exposure limits
TLV: 0.5 mg/m3, - ppm, as TWA.
MAK: (including its inorganic compounds, except stibine): carcinogen category: 2; germ cell mutagen group: 3B 

ENVIRONMENT
 

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