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 .
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

STORAGE

PACKAGING & LABELLING

Personal protection: P2 filter respirator for harmful particles. Sweep spilled substance into sealable containers; if appropriate, moisten first to prevent dusting.
Separated from oxidants , acids, halogens , food and feedstuffs.
Do not transport with food and feedstuffs.
UN Hazard Class: 6.1
UN Packing Group: III
ICSC: 0775 Prepared in the context of cooperation between the International Programme on Chemical Safety & the Commission of the European Communities (C) IPCS CEC 1994. No modifications to the International version have been made except to add the OSHA PELs, NIOSH RELs and NIOSH IDLH values.

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, , 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).
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) See: 7440360


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.

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.
