For operators, safety officers, environmental managers, and even curious neighbors, the SDS turns chemical mystery into actionable knowledge. It’s the document that prevents guesswork and keeps compliance inspectors happy. In facilities using Nalco products — boilers, cooling towers, pulp and paper, or process water systems — an SDS is not optional reading; it’s part of the job.
According to the GHS (Globally Harmonized System), Nalco 77352 is typically classified as:
Signal Word: WARNING (This is less severe than “DANGER,” but does not mean the product is safe.)
Precautionary Statements:
Posting an SDS binder is not enough. According to OSHA, you must train employees on where the SDS is located and how to interpret Sections 4-8 specifically for Nalco 77352.
Sample training checklist:
For compliance with OSHA, WHMIS, or other regulatory bodies, you must possess the official SDS.
