4   FIRST AID MEASURES

General Measures: Remove patient from area of exposure.

INHALATION: Remove to fresh air, keep warm and quiet, give oxygen if breathing is difficult. Seek immediate medical attention.

INGESTION: Rinse mouth with water. Do not induce vomiting. Seek immediate medical attention. Never induce vomiting or give anything by mouth to an unconscious person.

SKIN: Remove contaminated clothing, brush material off skin, wash affected area with soap and water. Seek medical attention if symptoms develop.

EYES: Flush eyes with lukewarm water, including under upper and lower eyelids, for at least 15 minutes. Seek medical attention if symptoms develop.

Most Important Symptoms/Effects, Acute and Delayed: May cause irritation and systemic poisoning with symptoms including abdominal pain, nausea, dizziness and dry throat. See section 11 for more information.

Indication of Immediate Medical Attention and Special Treatment: No other relevant information available.

 

 

5   FIREFIGHTING MEASURES

Extinguishing Media: Use gentle surface application of Class D or dry, inert granular material such as sand to cover and ring the burning material.

Unsuitable Extinguishing Media: Do not use water, carbon dioxide or halogenated extinguishing agents.

Specific Hazards Arising from the Material: When heated or in contact with acid, may release toxic fumes. Antimony powder with a particle size range of less than 74 microns is classified as weakly explosive by the U.S. Bureau of Mines, report RI-6516. When present as a dust cloud, will not explode readily in air and are not easily ignited by sparks.

Special Protective Equipment and Precautions for Firefighters: Wear full face, self-contained breathing apparatus and full protective clothing.

 

 

6   ACCIDENTAL RELEASE MEASURES

Personal Precautions, Protective Equipment, and Emergency Procedures: Wear appropriate respiratory and protective equipment specified in section 8. Isolate spill area and provide ventilation. Avoid breathing dust or fume. Avoid contact with skin and eyes. Eliminate all sources of ignition.

Methods and Materials for Containment and Cleaning Up: Sprinkle damp sand over spill. Scoop up and carefully transfer to a properly labeled closed container. Avoid creating dust.

Environmental Precautions: Do not allow to enter drains or to be released to the environment.

 

 

7   HANDLING AND STORAGE

Precautions for Safe Handling: Handle in an enclosed, controlled process. Avoid creating dust. Avoid breathing dust or fumes. Provide adequate ventilation if dusts are created. Avoid contact with skin and eyes. Wash thoroughly before eating or smoking. See section 8 for information on personal protection equipment.

Conditions for Safe Storage: Store in a cool, dry area. Store material tightly sealed in properly labeled containers. Store away from oxidizers, acids or halogens. Protect from heat. See section 10 for more information on incompatible materials.

 

 

8   EXPOSURE CONTROLS AND PERSONAL PROTECTION

Exposure Limits:     Antimony

OSHA/PEL:              0.5 mg/m3

ACGIH/TLV:             0.5 mg/m3

Engineering Controls: When working with finely divided powders, handle in a controlled, enclosed environment. Ensure adequate ventilation to maintain exposures below occupational limits. Whenever possible the use of local exhaust ventilation or other engineering controls is the preferred method of controlling exposure to airborne dust and fume to meet established occupational exposure limits. Use good housekeeping and sanitation practices. Do not use tobacco or food in work area. Wash thoroughly before eating or smoking. Do not blow dust off clothing or skin with compressed air.

Individual Protection Measures, Such as Personal Protective Equipment:

Respiratory Protection: Where airborne exposures may exceed OSHA/ACGIH permissible air concentrations, the minimum respiratory protection recommended is negative pressure air purifying respirator with cartridges that are NIOSH/MSHA approved against dusts, fumes and mists having a TWA less than 0.05 mg/m3

Eye Protection: Safety glasses

Skin Protection: Impermeable gloves, protective work clothing as necessary.

10   STABILITY AND REACTIVITY

Reactivity: No data

Chemical Stability: Stable under recommended storage conditions.

Possibility of Hazardous Reactions: Antimony may react violently with halogens such as fluorine, chlorine, or bromine. Antimony with iodine produces heat, which can cause flame or even explosion if quantities are great enough. Finely divided antimony on contact with acid emits toxic fumes of antimony hydride. Antimony will react with nascent (freshly formed) hydrogen to form stibine (SbH3) which is extremely toxic. Antimony can react violently with NH4NO3, BrN3, BrF3, HClO3, ClO, ClF3, HNO3, KNO3, KMnO4, NaNO3, sodium, sodium peroxide, and oxidizing agents.

Conditions to Avoid: Dusting conditions. Avoid high temperatures.

Incompatible Materials: Oxidizing agents, acids, halogens, nitrates, potassium permanganate, potassium and sodium peroxide.

Hazardous Decomposition Products: Antimony oxide fume, stibine.

 

 

11   TOXICOLOGICAL INFORMATION

Likely Routes of Exposure: Inhalation, skin and eyes.

Symptoms of Exposure:  May cause irritation and possibly systemic effects including a metallic taste in the mouth, vomiting, colic, loss of appetite and weight, and diarrhea.

Acute and Chronic Effects:  Acute systemic exposure to antimony compounds may cause loss of hair, dry scaly skin, and weight loss. Damage to the heart, liver, and kidneys can occur, and death from myocardial failure may follow. Fatalities from antimony poisoning are rare. The toxicity of elemental antimony has not been well studied, however, due to insolubility most elements in their metallic state are not considered to be serious health hazards.

Acute Toxicity: LD50 oral - rat - 7500mg/kg
