Precautionary statements

P210: Keep away from heat, hot surfaces, sparks, open flames and other ignition sources. Keep away from sparks/open flames/hot surface - no smoking P220: Keep/Store away from clothing - combustible materials. Keep- Store away from reductive and combustible materials, especially fuels, oils and greases P260: Do not breathe dust/fume/gas/mist/vapors/spray P280: Wear protective gloves/protective clothing/eye protection/face protection P305+P351+P338: IF IN EYES: Rinse cautiously with water for several minutes. Remove contact lenses, if present and easy to do. Continue rinsing. P273: Avoid release to the environment P370+P378: In case of fire: use water to extinguish. P371+P380+P375: In case of major fire and large quantities: Evacuate area. Fight fire remotely due to the risk of explosion.

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 ammonium perchlorate can be via water contaminated with ammonium perchlorate or inhalation in the workplace. With chronic exposure given sufficient dose (see (United States National Research Council) NRC, 2005) and duration, ammonium perchlorate can reduce uptake of iodine to the thyroid, 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. There is a risk of explosion if heated under confinement. Specific classification for Ammonium Perchlorate manufactured by American Pacific concerning physical hazards, American Pacific has demonstrated that Ammonium Perchlorate qualities with a median granulometry higher or equal to 70 µm do not present an explosive hazard (application of CLP regulation EC n°1272/2008 - note T) See 4.14 endpoint study record named "Explosiveness_UN_AmmoniumPerchlorate_AMPAC"
