PRECAUTIONS

Although antimony compounds must be considered toxic and are labeled accordingly, the metal and trioxide are practically innocuous due to their low solubility in water and body fluids. However, antimony oxide has caused dermatitis, popularly called "antimony measles", especially in hot humid areas where an individual perspires. Although respiratory irritation occurs, it can be prevented by the use of suitable respirators or by the coating of the oxide with wetting agents or plasticizers. No conclusive evidence indicates that antimony compounds are carcinogenic. Currently, the OSHA eight hour time weighted average (TWA) exposure limit is 0.5 mg/m3 of antimony with a short term exposure limit (STEL) of 0.75 mg/m3.
