Muriatic Acid (HCI)

Hazards

• Muriatic or hydrochloric acid causes severe irritation or burns to skin and eyes.

Handling

• Use only in well ventilated areas.
• Always add acid to water…never add water to acid.
• Do not mix muriatic acid with any other chemicals.

Management Options

• Do NOT dispose of in the trash: liquid wastes can leak in a trash truck and react with other chemicals.
