Erste Hilfe	EYES: First check the victim for contact lenses and remove if present. Flush victim's eyes with water or normal saline solution for 20 to 30 minutes while simultaneously calling a hospital or poison control center. Do not put any ointments, oils, or medication in the victim's eyes without specific instructions from a physician. IMMEDIATELY transport the victim after flushing eyes to a hospital even if no symptoms (such as redness or irritation) develop.
Freisetung ohne Brand	SMALL SPILLS AND LEAKAGE: Should a spill occur while you are handling this chemical, you should dampen the solid spill material with alcohol, then transfer the dampened material to a suitable container. Use absorbent paper dampened with alcohol to pick up any remaining material. Seal the absorbent paper, and any of your clothes, which may be contaminated, in a vapor-tight plastic bag for eventual disposal. Solvent wash all contaminated surfaces with alcohol followed by washing with a strong soap and water solution. Do not reenter the contaminate area until the Safety Officer (or other responsible person) has verified that the area has been properly cleaned.

Personal Protective Equipment (PPE)	MINIMUM PROTECTIVE CLOTHING: If Tyvek-type disposable protective clothing is not worn during handling of this chemical, wear disposable Tyvek-type sleeves taped to your gloves.

Treatment

Following oral exposure to antimony, administer charcoal as a slurry (240 mL water/30 g charcoal). Following inhalation exposure, move patient to fresh air. Monitor for respiratory distress. If cough or difficulty breathing develops, evaluate for respiratory tract irritation, bronchitis, or pneumonitis. Administer oxygen and assist ventilation as required. Treat bronchospasm with inhaled beta2 agonist and oral or parenteral corticosteroids. In case of eye exposure, irrigate exposed eyes with copious amounts of room temperature water for at least 15 minutes. Following dermal exposure, Remove contaminated clothing and wash exposed area thoroughly with soap and water. A physician may need to examine the area if irritation or pain persists. (T36)

Gesundheitliche Auswirkungen

Dermal exposure to antimony can cause antimony spots (papules and pustules around sweat and sebaceous glands). Antimony poisoning can also lead to pneumoconiosis. Alterations in pulmonary function and other effects including chronic bronchitis, chronic emphysema, inactive tuberculosis, pleural adhesions, and irritation can result from inhalation of antimony. Increased blood pressure can also result from antimony poisoning. Myocardial depression, vasodilation and fluid loss may cause shock with hypotension, electrolyte disturbances and acute renal failure. Cerebral oedema, coma, convulsions, and death are possible. (L741)

Toxizitätsübersicht

The inhalation data suggests that the myocardium is a target of antimony toxicity. It is possible that antimony affects circulating glucose by interfering with enzymes of the glycogenolysis and gluconeogenesis pathways. The mechanism of action of antimony remains unclear. However, some studies suggest that antimony combines with sulfhydryl groups including those in several enzymes important for tissue respiration. The antidotal action of BAL depends on its ability to prevent or break the union between antimony and vital enzymes. Moreover, the The cause of death is believed to be essentially the same as that in acute arsenic poisoning. (T18, L741, A238)

Signs and Symptoms	Abdominal pain, vomiting, diarrhea can result from inhalation of antimony. Dyspnea, headache, vomiting,cough, conjunctivitis, and bloody purulent discharge from nose can result from inhalation exposure. Skin or eye contact can cause pain and redness of the exposed surface.
