Hazardous chemicals can be solid, liquid, gas or a vapour and enter the body by being inhaled into the lungs, absorbed through the skin or ingested through the mouth. The effect of a hazardous chemical will depend on its toxicity and the extent and duration of the exposure. An obvious hazardous chemical is a poison such as cyanide.

There are 4 distinct methods used to mine the Wyoming trona ore: (1) solution mining, (2) room-and-pillar, (3) longwall, and (4) shortwall. In solution mining, dilute sodium hydroxide (NaOH), commonly called caustic soda, is injected into the trona to dissolve it. This solution is

In solution mining, dilute sodium hydroxide (NaOH), commonly called caustic soda, is injected into the trona to dissolve it. This solution is treated with CO2 gas in carbonation towers to convert the Na2CO3 in solution to NaHCO3, which precipitates and is filtered out.
