Personal precautions: Evacuate non-essential personnel. Increase ventilation. Wear acid-resistant gloves (neoprene, nitrile), goggles, face shield, and apron.
Environmental precautions: Prevent entry into drains, ditches, or surface water. Molybdate is moderately toxic to fish (LC50 50–200 mg/L for some species).
Cleanup methods:
The Nalco 73385 Material Safety Data Sheet (MSDS), now more commonly referred to as a Safety Data Sheet (SDS), provides critical information for the safe handling, storage, and disposal of this industrial water treatment chemical. Produced by Nalco Water, an Ecolab company, Nalco 73385 is a specialized non-oxidizing biocide designed to control biological growth in industrial systems. Product Overview and Application
Nalco 73385 is a broad-spectrum, non-oxidizing biocide primarily used for cooling water bio-control. It is engineered to target microorganisms that cause operational issues in recirculating cooling towers and closed-loop systems.
Effective Targets: It is particularly potent against slime-forming bacteria and sulfate-reducing bacteria (SRB), which are known to cause localized corrosion and fouling.
Ideal Use Cases: Due to its persistence and efficacy at elevated pH levels, it is frequently used in closed water loops where maintaining microbial control over long periods is essential. Physical and Chemical Properties
According to technical data from HKCT Malaysia, Nalco 73385 typically exhibits the following characteristics: Physical Form Colour Colorless to yellow Odor Pungent or sweet pH (Neat) Specific Gravity 1.13 @ 20°C Solubility in Water Freezing Point Flash Point Not flammable Hazard Identification and Safety Typical user complaints (from industrial forums):
While specific MSDS details can vary by region, Nalco biocides in this category are generally classified as hazardous materials.
Health Hazards: Exposure can cause irritation or burns to the skin and eyes. If the product contains certain active ingredients like isothiazolinones (common in related products like Nalco 7330), it may cause allergic skin reactions or sensitization.
Reactivity: The product is stable under normal conditions but should be kept away from high temperatures and strong oxidizers like chlorine, peroxides, or nitric acid, which can trigger hazardous reactions or toxic fumes.
Environmental Impact: As a biocide, it is inherently toxic to aquatic life. Disposal must be handled strictly according to local regulations and FIFRA labels for pesticide wastes. Handling and Storage Recommendations

Title: Technical Feature: Understanding the Safety and Handling Profile of Nalco 73385
Introduction In industrial water treatment and process applications, chemical safety is paramount. Nalco 73385 is a specialized chemical product used primarily for corrosion and scale inhibition. To ensure safe handling, storage, and emergency response, facility managers and safety officers rely on the Material Safety Data Sheet (MSDS), now more commonly referred to as the Safety Data Sheet (SDS) under Globally Harmonized System (GHS) standards. This feature explores the critical technical components found within the Nalco 73385 SDS, highlighting why this document is essential for operational compliance and workplace safety.
1. Product Identity and Chemical Composition 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.
2. Hazard Identification (GHS Classification) The most critical section of the SDS is the hazard identification. Modern SDS documents for Nalco 73385 utilize GHS pictograms and signal words to convey risk immediately.
3. First-Aid Measures The SDS provides a definitive guide for immediate response in the event of accidental exposure. Because Nalco 73385 is designed to interact with metal surfaces, it can be harsh on human tissue.
4. Fire-Fighting Measures While Nalco 73385 is generally aqueous (water-based) and not highly flammable, the SDS outlines safety measures for fire scenarios where the chemical might be present.
5. Accidental Release and Handling Spill management is a key operational feature of the SDS.
6. Storage and Stability To maintain efficacy and safety, the SDS outlines specific storage conditions.
Conclusion: The Value of the SDS The Nalco 73385 MSDS/SDS is more than a regulatory requirement; it is a technical blueprint for safety. By understanding the specific hazard classifications, first-aid protocols, and storage requirements outlined in the document, industrial facilities can mitigate risks to personnel and the environment. For operators using Nalco 73385, maintaining a current, accessible copy of the SDS at the worksite is the standard for operational excellence and safety compliance.
