Concentrated hydrochloric acid (fuming hydrochloric acid) will emit acid mist. Hydrochloric acid itself and acid mist will corrode human tissues, which may cause irreversible damage to respiratory organs, eyes, skin and gastrointestinal tract. When hydrochloric acid is mixed with oxidant (such as bleaching agent sodium hypochlorite or potassium permanganate, etc.). ), will produce toxic gas chlorine.

People often wear personal protective equipment to reduce the harm caused by handling hydrochloric acid, including latex gloves, goggles, corrosion-resistant clothing and shoes. The National Environmental Protection Agency of the United States has designated hydrochloric acid as a toxic substance.
