What will happen if calcium chloride is left exposed to air?

If anhydrous calcium chloride is exposed to air, it will absorb sufficient water from the air to allow it to dissolve. After a short while, instead of a white lump, you will have a pool of clear liquid. So, anhydrous calcium chloride is a deliquescent that is why it turns colourless when exposed to air.

Is a calcium chloride dehumidifier safe?

Some powered dehumidifiers rely on fans to circulate air over calcium chloride salts, and this exposes the air to minimal amounts of this chemical. Unfortunately, over time exposure to calcium chloride and its dust can cause lung damage, as well as other respiratory issues in the nose and throat.

How much calcium chloride is toxic?

Acute Toxicity

Acute oral toxicity of calcium chloride has been tested in several mice, rat and rabbit studies. The oral lethal median doses (LD50s) values range from 2120–3798 (male) and 2361–4179 (female) mg/kg bw in rats to 2045 (male) and 1940 (female) mg/kg bw in mice (Akatsuka, 1997).
