As a non-oxidizing biocide, the formulation is engineered to eradicate cellular organisms like bacteria and algae within closed systems. Consequently, any unneutralized discharge into the environment is highly toxic to aquatic life, posing severe risks to local water ecosystems. 3. Essential First Aid Measures
According to verified technical specifications and safety documentation, NALCO 73385 exhibits the following core physical characteristics: Value / Specification Color Odor Sweet, distinctive Density 1.16 - 1.20 kg/L pH (Neat) 12.6 - 13.0 (Highly Alkaline) Solubility in Water Viscosity (@ 20°C) Freezing Point -6°C (Complete freeze-thaw recovery) Flash Point None (Non-flammable aqueous solution) Critical Hazard Identification & Safety Profiles
Ensure your team has read the verified SDS, that your PPE stations are stocked according to the requirements, and that your emergency eye-wash stations are functional. Safety starts with the data sheet.
Why? An unverified or outdated Material Safety Data Sheet (MSDS)—now formally known as a Safety Data Sheet (SDS) under GHS (Globally Harmonized System)—can lead to regulatory fines, improper handling, medical emergencies, and environmental disasters. This article provides a verified, authoritative breakdown of the Nalco 73385 MSDS, covering composition, hazards, first aid, storage, spill control, and regulatory compliance.
. It is particularly effective at controlling slime-forming and sulfate-reducing bacteria, even at elevated pH levels. HKCT Malaysia Verified Technical & Safety Specifications The following data is typical for NALCO 73385 based on verified technical sheets: Physical Form: Appearance: Colorless to yellow pH (Neat): Approximately 3.7 1.13 kg/L at 20°C Solubility: Complete in water Flammability: Not flammable or combustible HKCT Malaysia Safety & Handling Precautions Hazard Identity:
: This formulation is highly toxic to fish and aquatic life. It must never be discharged directly into public waterways, streams, or lakes without proper treatment. Safe Handling, Storage, and PPE Requirements
To ensure safe handling and use of Nalco 73385, follow these best practices:
A verified MSDS serves as your primary defense during an inspection, proving you have made a good-faith effort to communicate hazards.
: Because it does not rely on oxidation, it does not increase the underlying corrosivity of the water or damage sensitive system metallurgy. Verified Physical and Chemical Properties
Subscriptions to services like , SDS Manager , or Chemwatch offer verified, watermarked documents that are updated automatically. Always cross-check the document ID with the manufacturer’s latest revision.
: Keep the product in its original, tightly sealed container in a cool, well-ventilated area. Regulatory Compliance Employers using Nalco 73385 are required by (in the US) and similar international bodies to keep a verified and up-to-date SDS
: Prolonged exposure causes tissue damage and skin burns. It may cause allergic skin reactions or sensitization over time.
: Corrosive to the mouth, throat, and stomach. Risk of bronchopneumonia if liquid is aspirated into the lungs.
A: It depends on use. If it contains heavy metals picked up from the system, it may be regulated. Test via TCLP. The neat product is not an RCRA hazardous waste but is a corrosive liquid.
