Nalco 73385 Msds -
High persistency and efficacy in closed water loops where long-term bacterial control is required. 2. Hazard Identification
If you are a facility manager, engineer, or safety officer who uses Nalco N7385, the only reliable sources for the official, regulatory-compliant MSDS are:
Use water spray, alcohol-resistant foam, dry chemical, or carbon dioxide ( CO2cap C cap O sub 2
Workers handling Nalco 73385 must wear standard industrial PPE:
This article focuses on the safety data sheet for a specific product: , a water treatment chemical manufactured by Nalco Water, now a subsidiary of Ecolab. While the official SDS for Nalco 73385 may not be directly available online, this guide will provide a thorough analysis based on publicly available procurement data, information on similar products, and general guidelines on how to interpret and obtain safety data. nalco 73385 msds
The mixture is classified under the UN Globally Harmonized System (GHS) in multiple hazard classes:
Firefighters must wear a self-contained breathing apparatus (SCBA) and full protective bunker gear. Spill Containment (Accidental Release)
: May cause significant irritation or chemical burns with prolonged or direct contact.
None known.
The —now universally referred to as a Safety Data Sheet (SDS)—is a regulatory compliance document detailing the chemical properties, safety hazards, handling protocols, and emergency measures for NALCO 73385. Manufactured by Nalco Water, this product is a liquid, high-pH, broad-spectrum non-oxidizing biocide specifically engineered to control biological growth, slime-forming bacteria, and sulfate-reducing bacteria in industrial recirculating cooling towers and closed-loop water systems.
Prolonged skin contact may cause dermatitis. Molybdenum compounds are not classified as carcinogens (IARC Group 3 – not classifiable). However, ingestion of large amounts can cause gout-like symptoms (elevated uric acid).
The SDS for Nalco 73385 serves as the primary identifier for the substance. It details the chemical nature of the product, which is typically a proprietary blend of phosphonates, polymers, and other corrosion inhibitors used in cooling water systems.
In case of accidental exposure, immediate deployment of basic first-aid protocols is essential before professional medical staff arrive: High persistency and efficacy in closed water loops
Proper management is essential to prevent environmental contamination and workplace injury.
This classification is important because scale inhibitors are typically formulated with strong (often phosphonic or sulfuric acids) and surfactants . The procurement listing confirms this, specifying the physical state as a pale yellow liquid and the pH range as 1.0 to 2.0. This extremely low pH indicates the product is severely corrosive . The specific gravity of the solution is listed as 1.3 to 1.45, indicating it is much denser than water.
: As a biocide, the product is toxic to aquatic life. Discharge of treated water must comply with local environmental regulations regarding chemical additives. files.dep.state.pa.us First Aid Measures Eye Contact
