The MCMUA operates one of NJ's most comprehensive household hazardous waste (HHW) programs. This F.A.Q. page and information on hazardous materials is intended as a guide about HHW materials as well as the MCMUA's HHW program. This information is a general guide and does not constitute official rule, regulation or law.

Hazards

• Muriatic or hydrochloric acid causes severe irritation or burns to skin and eyes.
• Vapors may irritate respiratory tract.
   

Handling

• Wear clothing that covers exposed skin areas. Use gauntlet-style acid-resistant gloves and eye protection when working with acid.
• 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 down the drain or in storm drains.
• Do NOT dispose of in the trash: liquid wastes can leak in a trash truck and react with other chemicals.
• Wastewater treatment facilities routinely use muriatic acid. Call your local facility to see if they will accept it.
• Take to a HHW collection or commercial hazardous waste facility.
