Why is hydrochloric acid referenced in SS60 bitumen emulsion MSDS and how does it affect safety procedures?

Hydrochloric acid is commonly used to adjust pH during soap preparation for cationic emulsions. Its presence introduces corrosion and chemical burn hazards, requiring acid resistant materials, PPE, and controlled dosing systems. Safety procedures must address acid storage, spill neutralization, and emergency response. Even though final emulsion is diluted, plant level handling of acid defines the main safety risk.
