Chemical Safety
1255 AMMONIUM PERCHLORATE
IMPORTANT DATA
Physical State; Appearance Routes of exposure
WHITE HYGROSCOPIC CRYSTALS The substance can be absorbed into the body by inhalation of its aerosol
and by ingestion.
Chemical dangers
May decompose explosively on shock, friction, or concussion. and on Inhalation risk
heating. The substance is a strong oxidant and reacts violently with A harmful concentration of airborne particles can be reached quickly when
combustible and reducing materials and metals, producing toxic and dispersed
corrosive fumes, including ammonia and hydrogen chloride, causing fire
and explosion hazard. Effects of short-term exposure
The aerosol is irritating to the eyes, the skin and the respiratory tract.
Occupational exposure limits
TLV not established. Effects of long-term or repeated exposure
MAK not established. The substance may have effects on the thyroid, resulting in reduced levels
of thyroid hormones.
