Poisoning may be caused by ingestion of mild acids in liquid form, ingestion of solid chlorine tablets, acid burns to the skin, or inhalation of chlorine dust or fumes. Chlorine is more likely to cause serious toxicity than the acids.

Expectations (prognosis)

Chlorine in high doses can be extremely toxic. The acids may also be extremely toxic in very high doses. Extensive damage to the mouth, throat, and stomach are possible. The ultimate outcome will depend on the extent of this damage.
