Nalco 77225 Safety Data Sheet ^new^

Usually "Danger" (due to eye damage severity). Hazard Statements: H315 (Causes skin irritation), H318 (Causes serious eye damage), H335 (May cause respiratory irritation). Precautionary Statements: P280 (Wear protective gloves/eye protection), P305+P351+P338 (IF IN EYES: Rinse cautiously with water for several minutes).

Based on NALCO’s product numbering, 77225 is typically a specialty industrial water treatment chemical (e.g., a corrosion inhibitor, scale inhibitor, or biocide). You must confirm the exact chemical identity from the official SDS.

| Section | Title | Typical Information for NALCO 77225 (Hypothetical) | | :--- | :--- | :--- | | | Identification | Product: NALCO® 77225. Uses: Scale/corrosion control in cooling towers or boilers. Emergency phone: Chemtrec (USA) or local poison control. | | 2 | Hazard Identification | Likely classified as: Skin corrosion/irritation (Category 1 or 2), Serious eye damage (Category 1), May be corrosive to metals. Signal word: DANGER or WARNING . | | 3 | Composition/Info | Proprietary blend. Typically contains: Phosphonates, polymers, azoles (e.g., benzotriazole), and possibly a low concentration of inorganic acids or caustic (pH adjusters). Exact % are trade secret. | | 4 | First Aid Measures | Eyes: Rinse immediately with water for 15+ minutes, get medical aid. Skin: Wash with soap/water. Remove contaminated clothing. Ingestion: Do NOT induce vomiting. Rinse mouth. Drink water. Call MD. | | 5 | Firefighting | Usually not flammable. Use water fog, CO2, dry chemical. Hazardous decomposition: may emit oxides of phosphorus, nitrogen, or carbon. | | 6 | Accidental Release | Contain spill with inert absorbent (clay, sand). Neutralize if acidic/caustic (check pH). Prevent entry into drains. Wear PPE (gloves, goggles, apron). | | 7 | Handling/Storage | Store in original container, away from incompatible materials (strong oxidizers, acids, bases – depending on product pH). Prevent freezing. Use with adequate ventilation. | | 8 | Exposure Controls/PPE | Gloves: Nitrile or neoprene. Eye: Chemical safety goggles. Skin: Apron & boots. Respiratory: Usually not needed if mist controlled; otherwise use particulate respirator. | | 9 | Physical/Chemical | Appearance: Liquid, clear to hazy. pH: Usually 2–5 (acidic) or 11–13 (alkaline) – check your SDS . Soluble in water. | | 10 | Stability/Reactivity | Stable under normal conditions. Avoid: High heat, incompatible chemicals (bleach, strong acids/bases). | | 11 | Toxicological | May cause moderate to severe eye/skin irritation. Not likely to be a carcinogen (based on proprietary data). | | 12 | Ecological | Toxic to aquatic life in high concentrations. Do not discharge undiluted product into water bodies. | | 13 | Disposal | Follow local, state, and federal regulations. Can often be neutralized and sent to a WWTP if permitted. Do not incinerate closed containers. | | 14 | Transport | May be classed as Corrosive liquid, N.O.S. (UN 1760 or 3265) if pH ≤2 or ≥11.5. | | 15 | Regulatory | TSCA (US), DSL (Canada), EINECS (EU) compliant. May be subject to SARA 313 reporting depending on ingredients. | | 16 | Other Info | Revision date, NFPA diamond (typically Health=3, Fire=0, Reactivity=0), HMIS ratings. | nalco 77225 safety data sheet

Use only with adequate ventilation to avoid breathing vapors or mists. Personal Hygiene:

Nalco 77225 is designed for in boilers operating at pressures up to 40 barg. It utilizes "Transport Plus" polymer technology to prevent calcium and magnesium deposits from sticking to boiler tubes. Because of its high alkalinity (pH >13), it is incompatible with aluminum, copper, brass, and zinc, which can react and corrode rapidly. For large spills, the Official SDS via Scribd recommends containing the liquid with non-combustible absorbent materials like sand or earth and ensuring runoff does not reach waterways. Usually "Danger" (due to eye damage severity)

Wash hands and any exposed skin thoroughly after handling. Remove and wash contaminated clothing before reuse.

Includes date of preparation, last revision date, disclaimer, and key to abbreviations. —an SDS older than 3 years may be out of compliance. Based on NALCO’s product numbering, 77225 is typically

, an alkaline internal boiler treatment designed for scale control in feedwater systems. Core Safety Information
