The Safety Data Sheet for Nalco 77225 is not merely a technical formality; it is a legal and practical lifeline for personnel. Mandated globally by standards such as OSHA’s Hazard Communication Standard (HCS) in the United States and the Globally Harmonized System (GHS), the SDS provides a standardized, 16-section breakdown of the chemical. For a product like Nalco 77225, which typically contains active biocidal ingredients, the SDS functions as the first line of defense against occupational hazards.

Move the individual to fresh air and keep them comfortable for breathing. Treat symptomatically. 5. Storage and Compatibility

The complex phosphate component reacts with calcium and magnesium, while the Transport Plus organic polymer prevents adherent scale deposits. This maintains boiler system efficiency, optimizes steam production runs, and protects against tube overheating.

Nalco 77225 is chemically stable under normal operational and ambient conditions. However, its high pH makes it highly reactive with specific substances: Solubility : Completely soluble in water

The Safety Data Sheet (SDS) identifies this product as a corrosive boiler water treatment primarily composed of Potassium Hydroxide and Tetrapotassium Pyrophosphate . It is designed for scale control in industrial boilers by preventing the formation of adherent deposits. Core Safety Data

A deeper analysis of the Nalco 77225 SDS reveals the critical importance of Sections 4 through 6, which cover first-aid measures, firefighting measures, and accidental release measures. The health implications of mishandling industrial biocides can be severe. The SDS details the specific pathways of exposure—inhalation, skin contact, ingestion, and eye contact.

Based on information from similar Nalco products and the properties of the chemical constituents, NALCO 77225 is considered non-flammable and non-combustible. However, when involved in a fire, the product may decompose or evolve hazardous gases, specifically oxides of carbon (CO, CO₂).
