Why should people avoid using Calcium Chloride icemelters?
Beside the fact that calcium chloride causes damage to concrete by having a very short thaw/freeze cycle, and causes discolouration of concrete, Calcium Chloride inherently attracts moisture – is hygroscopic – and therefore has a limited shelf life. Further, Calcium chloride leaves behind an oily residue, which is easily tracked into buildings, soiling and damaging carpets and floorings and presenting a serious slip/fall hazard. Perhaps most frighteningly, it is harmful to the environment – damaging plant life, soil and the water system. Also, people must be very careful when using calcium chloride as it caustic and will burn skin causing an irritation. It should not be used around pets as it will burn their paws and irriatate their noses.
