Other uses

Hydrochloric acid is used in the production of batteries, flash bulbs and fireworks. It is also used in leather processing, building construction, oil well acidification and the production of gelatin products.

Caution! Dangers

Concentrated hydrochloric acid has a strong, irritating odor and is highly corrosive. According to the U.S. National Library of Medicine, exposure may cause damage, such as chemical burns. Ingestion of concentrated hydrochloric acid can cause serious injury to the mouth, throat, esophagus and stomach. When handling hydrochloric acid, use personal protective equipment , such as vapor-proof respirators, rubber gloves, splash-proof goggles and face shields. If used in the workplace, it is recommended to have an eye wash to prevent accidental exposure.

When using pool cleaners containing hydrochloric acid (also known as muriatic acid), always follow the instructions on the product label for safe handling.
