Used in both commercial and home setting
Rust remover (most common home use)
Glass etching, chrome and other metal cleaning, petroleum processing
Oral ingestion has very high mortality rate
Onset and severity of symptoms correlated with concentration
Dilute solutions (<20%) may have delayed onset up to 24hr post-exposure
Moderate solutions (20-50%) develop symptoms within 1-8hr
Concentrated solutions (>50%) develop symptoms immediately
These patients are at highest risk for systemic toxicity/death
Pain immediately (even if wound appears minor) implies severe injury
Burn itself may appear relatively minor
Toxicity caused by binding of calcium and magnesium leading to electrolyte derangement and myocardial dysfunction
