International Chemical Safety Cards ANTIMONY ICSC: 0775 Antimony black Antimony regulus Stibium Sb Atomic mass: 121.8 ICSC #    0775 CAS #     7440-36-0 RTECS # CC4025000 UN #        2871 October 08, 1997 Peer reviewed TYPES OF HAZARD/ EXPOSURE ACUTE HAZARDS/ SYMPTOMS PREVENTION FIRST AID/ FIRE FIGHTING FIRE Gives off irritating or toxic fumes (or gases) in a fire. NO open flames. Water spray, powder. EXPLOSION Finely dispersed particles form explosive mixtures in air. Risk of fire and explosion on contact with strong oxidants. Prevent deposition of dust; closed system, dust explosion-proof electrical equipment and lighting. In case of fire: keep drums, etc., cool by spraying with water. EXPOSURE PREVENT DISPERSION OF DUST! STRICT HYGIENE!  •INHALATION Cough. Vomiting. (See Ingestion). Local exhaust or breathing protection. Fresh air, rest.  •SKIN Dry skin. Protective gloves. Protective clothing. Remove contaminated clothes. Rinse and then wash skin with water and soap.  •EYES 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. Burning sensation. Diarrhoea. Vomiting. Death. Do not eat, drink, or smoke during work. Rinse mouth. Rest. Refer for medical attention. SPILLAGE DISPOSAL STORAGE PACKAGING & LABELLING Sweep spilled substance into containers; if appropriate, moisten first to prevent dusting. Carefully collect remainder, then remove to safe place. (Extra personal protection: P2 filter respirator for harmful particles). Separated from strong oxidants, acids, food and feedstuffs. Do not transport with food and feedstuffs.

No modifications to the International version have been made except to add the OSHA PELs, NIOSH RELs and NIOSH IDLH values.

International Chemical Safety Cards ANTIMONY ICSC: 0775 I M P O R T A N T D A T A PHYSICAL STATE; APPEARANCE: SILVER-WHITE, LUSTROUS, HARD, BRITTLE METAL 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). Reacts violently with oxidants (e.g. halogens, alkali permanganates, nitrates), and powdered metals causing fire and explosion hazard. On contact with acids may emit toxic gas (stibine). See ICSC 0776. OCCUPATIONAL EXPOSURE LIMITS: TLV (as Sb): 0.5 mg/m3 (as TWA) (ACGIH 1997). MAK as Sb: 0.5 mg/m3; (1996). OSHA PEL*: TWA 0.5 mg/m3 *Note: The PEL also applies to other antimony compounds (as Sb). NIOSH REL: TWA 0.5 mg/m3 *Note: The REL also applies to other antimony compounds (as Sb). NIOSH IDLH: 50 mg/m3 (as Sb) 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. EFFECTS OF SHORT-TERM EXPOSURE: Exposure by ingestion could cause gastrointestinal irritation. Exposure far above the OEL may result in death. 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 eye, respiratory tract and lungs , resulting in pneumoconiosis. PHYSICAL PROPERTIES Boiling point: 1635°C Melting point: 630°C Relative density (water = 1): 6.7 Solubility in water: none Vapour pressure, Pa at 886°C: 133 ENVIRONMENTAL DATA N O T E S Other boiling points: 1325°C, 1440°C, 1750°C. Depending on the degree of exposure, periodic medical examination is indicated. Transport Emergency Card: TEC (R)-61G11c ADDITIONAL INFORMATION ICSC: 0775 ANTIMONY (C) IPCS, CEC, 1994
