Nalco 73385 Msds

NALCO 73385 is a broad-spectrum, non-oxidizing biocide primarily used to control slime-forming and sulfate-reducing bacteria in recirculating cooling towers and closed-loop systems. HKCT Malaysia Key Product Information Application:

Specifically designed for closed water loops due to its efficacy at elevated pH and its chemical persistency. Hazard Profile:

While full MSDS/SDS details for this specific product are often restricted, related Nalco biocide formulations (like 7338) are classified as and can cause irreversible eye damage and skin burns. Environmental Impact:

It may meet criteria for hazardous waste (RCRA) and is considered acutely hazardous to the environment if disposed of improperly. HKCT Malaysia Safety and Handling (General Guidelines)

Based on typical safety requirements for Nalco water treatment biocides: Personal Protective Equipment (PPE): Wear a face shield and chemical splash goggles.

Use impervious gloves (nitrile or butyl), rubber boots, and a chemical-resistant apron. Respiratory: Use in well-ventilated areas to avoid breathing vapors. Emergency Measures: Eye Contact:

Immediately flush with water for at least 15 minutes and seek medical advice.

Avoid contact; use liquid-binding materials like sand for cleanup and prevent the product from entering drainage systems. files.dep.state.pa.us How to Obtain the Official MSDS

NALCO 73385 is a broad-spectrum, non-oxidizing biocide primarily used to control slime-forming and sulfate-reducing bacteria in recirculating cooling towers and closed-loop systems. 

The following guide summarizes critical safety and handling information based on typical Safety Data Sheet (SDS) standards for this product.  1. Product Identification & Application  Product Name: NALCO 73385.

Primary Function: Biocide for industrial water systems, specifically effective at elevated pH levels.

Key Benefit: High persistency and efficacy in closed water loops where long-term bacterial control is required.  2. Hazard Identification 

NALCO 73385 is classified as a hazardous chemical. Common hazards include: 

Skin/Eye Contact: May cause irritation with prolonged or repeated exposure.

Ingestion: Can cause gastrointestinal irritation, nausea, and vomiting.

Environmental Impact: As a biocide, it is designed to kill microorganisms and must be managed carefully to avoid contaminating fresh water aquifers or natural water bodies.  3. Personal Protective Equipment (PPE)  Flash point: Typically >200°F (93°C) – not flammable

When handling NALCO 73385, the following Personal Protection is typically required: 

Eye Protection: Chemical safety goggles; a face shield may be necessary if splashing is possible.

Skin Protection: Chemical-resistant gloves (e.g., nitrile or neoprene), protective aprons, and boots. Respiratory Protection: Use in a well-ventilated area.  4. First Aid Measures  Condition  Immediate Action Eye Contact

Rinse immediately with plenty of water for at least 15 minutes. Remove contact lenses and seek medical advice. Skin Contact

Wash immediately with soap and plenty of water. Remove contaminated clothing. Inhalation

Move to fresh air. If not breathing, call emergency services and provide artificial respiration. Ingestion

Do not induce vomiting. Aspiration may cause lung damage. Seek prompt medical consultation. 5. Firefighting & Accidental Release 

Fire Hazards: Not flammable or combustible. However, fire conditions may evolve toxic oxides of carbon ( COxcap C cap O sub x ) or phosphorus ( POxcap P cap O sub x ). Section 4: Composition / Information on Ingredients The

Spill Response: Contain the spill to prevent it from entering drains or watercourses. Absorb with inert materials (e.g., sand or earth) and dispose of in accordance with local regulations.  6. Storage & Handling 

Storage: Keep containers tightly closed in a cool, well-ventilated area.

Handling: Avoid contact with eyes, skin, and clothing. Ensure adequate ventilation to prevent inhalation of vapors. 

Occupational Exposure Limits

No specific PEL (Permissible Exposure Limit) listed for the blend; limits apply to individual components (e.g., 2 mg/m³ for phosphonates, if established).

Section 14: Training Your Team on the Nalco 73385 MSDS

Having the document is useless if workers cannot interpret it. Implement these steps:

Section 6: Fire Fighting Measures

• Flash point: Typically >200°F (93°C) – not flammable but may decompose at high heat.
• Extinguishing media: Use alcohol-resistant foam, CO₂, dry chemical, or water spray.
• Special hazards: Heating may release toxic fumes including oxides of phosphorus or carbon monoxide.
• Protective equipment for firefighters: Full self-contained breathing apparatus (SCBA) and full protective gear.

Section 4: Composition / Information on Ingredients

The SDS will present a table like the one below (example only — actual data varies):

| Chemical Name | CAS Number | Weight % | GHS Hazard Class | |---------------|------------|----------|------------------| | Proprietary phosphonate blend | Proprietary | 10–30 | Skin Irrit. 2, Eye Dam. 1 | | Sodium hydroxide (if used as pH stabilizer) | 1310-73-2 | <1 | Corrosive, Met. Corr. 1 | | Water | 7732-18-5 | Balance | Not hazardous |

Note: If the supplier claims "trade secret," they must still provide hazard information but may redact exact concentrations.
