Safety

Hydrochloric acid in high concentrations forms acidic mists. Both the mist and the solution have a corrosive effect on human tissue, with the potential to damage respiratory organs, eyes, skin, and intestines. Upon mixing Muriatic acid with common oxidizing chemicals, such as bleach (NaClO) or permanganate (KMnO₄), the toxic gas chlorine is produced. To minimize the risks while working with hydrochloric acid, appropriate precautions should be taken, including wearing rubber or PVC gloves, protective eye goggles, and chemical-resistant clothing.
 

• Controls barium, strontium, and calcium sulphate scales effectively.
• Provides strong inhibition of calcium carbonate scaling.
• Designed specifically for formation scale squeeze applications.
• Delivers extended squeeze life through controlled inhibitor release.
