Potential Acute Health Effects

Eye irritation, redness, tearing Skin Irritating to mucous membranes and skin Inhalation may cause respiratory tract irritation; coughing, and shortness of breath; high Concentrations may cause more significant respiratory effects Ingestion may cause gastrointestinal irritation; larger doses my cause nausea and vomiting Potential chronic effects Perchlorates act to reversibly and competitively inhibit iodine uptake by the thyroid gland. Perchlorate is soluble in water, so exposure to sodium perchlorate can be via water contaminated with sodium perchlorate or inhalation in the workplace. With chronic exposure given sufficient dose (see (United States National Research Council) NRC, 2005) and duration, sodium perchlorate can cause thyroidal stores of iodine to be reduced, which may lead to hypothyroidism. For workers that live in areas of the world with endemic iodine deficiency, it is important that these people receive adequate iodine in the diet or are supplemented with iodine. Information pertaining to particular dangers for man and environment May be explosive when mixed with combustible material. Risk of explosion if heated under confinement
