Thermal decomposition can lead to the release of irritating or toxic gases, including oxides of carbon, nitrogen, or sulfur.
Depending on its active components, Nalco 77352 may be classified under GHS categories for skin irritation, serious eye damage, or acute aquatic toxicity.
NALCO 77352 is a specialized industrial chemical product manufactured by Ecolab, designed primarily for microbial control in water treatment systems. It is commonly used as a cooling water biocide to prevent fouling and ensure maximum system efficiency. Because this product is a powerful industrial biocide, obtaining and understanding the —now officially known as the SDS (Safety Data Sheet) —is critical for safe operation, handling, and environmental compliance.
Here are the key sections from the MSDS:
: Keep containers tightly closed in a cool, well-ventilated area, away from children and unauthorized personnel. Spill Management nalco 77352 msds
While the exact proprietary formulation is confidential, the MSDS reveals functional categories:
Keep containers closed. Store in a cool, dry place in suitable labeled containers. Environmental and Ecological Information NALCO 77352 is highly toxic to aquatic organisms .
Ensure compliance with the Resource Conservation and Recovery Act (RCRA) in the US, or equivalent local regulations regarding industrial chemical waste.

Nalco 77352 is a specialized chemical formulation utilized across various industrial water treatment and process optimization applications. For health and safety managers, industrial operators, and environmental compliance officers, understanding the Material Safety Data Sheet (MSDS)—now more commonly referred to as the Safety Data Sheet (SDS)—is critical.
: Sweep the saturated absorbent into labeled, secure waste drums for disposal through an approved hazardous waste facility. Clean the residual spill boundary area with copious amounts of water. 7. Handling and Storage Requirements Safe Handling Protocols NALCO® 77352NA
