Handling and Storage

Hydrochloric acid is corrosive. It should be stored away from oxidizing agents and alkaline materials in a cool, dry, ventilated place. Although stable under normal conditions, hydrochloric acid reacts with metals to form explosive and flammable hydrogen gas. Adding water to hydrochloric acid produces a violent, exothermic reaction.

When fighting fires or acid spills, proper protective clothing and respiratory equipment should be utilized and unprotected personnel should be moved upwind of the area.Large spills must be reported to the QVC Emergency No. 4476 5800.
