Nalco 77225 Safety Data Sheet 2021 ((top)) Jun 2026

When plumbing feeding loops or selecting pump internal elements, system designers must cross-reference material compatibility to prevent premature degradation or chemical leaks:

: This mechanism prevents the crystallization of adherent scale on high-heat transfer areas, lowering tube overheating risks, optimizing steam production cycles, and slashing routine outage maintenance windows.

Wash out the mouth thoroughly with water. Do not induce vomiting unless explicitly directed by medical personnel. Never give anything by mouth to an unconscious person. Induce drinking of water or milk if conscious and alert, then seek immediate emergency medical care. Handling, Storage, and Engineering Controls nalco 77225 safety data sheet 2021

Always wear chemical splash goggles, protective gloves (Neoprene, Nitrile, or PVC), and a face shield when handling. Storage Conditions:

Nalco 77225 is an internal boiler treatment designed to maintain proper co-ordinated phosphate-pH control parameters. It is commonly used to prevent rapid boiler system scaling and corrosion. Appearance: Colorless liquid. Odor: Ammoniacal. pH: 13.5 (highly alkaline). Solubility: Completely soluble in water. Nalco 77225 SDS: Key Sections & Safety Information When plumbing feeding loops or selecting pump internal

The SDS provides information on toxicological effects:

Flood the affected area with water while removing contaminated clothing and shoes. Continue flushing for a minimum of 15 minutes. Seek medical evaluation immediately. Wash clothing before reuse. Never give anything by mouth to an unconscious person

Move the affected person to fresh air and keep them comfortable for breathing. Safe Handling and Storage

In case of contact, rinse skin/eyes immediately with water for 15 minutes, removing contact lenses if necessary . If swallowed, do not induce vomiting and seek immediate medical attention . Inhalation requires moving to fresh air .

Due to its high pH of 13.5, the solution can inflict rapid, irreversible chemical burns on living tissues. Implementing standardized engineering controls and personal protective equipment (PPE) mitigates these operational risks.
