To obtain the official 2021 document for regulatory compliance, submit a direct request via the Ecolab SDS request portal nalco 93033 - NSF
Understanding NALCO 93033: 2021 Safety Data Sheet (SDS) Overview
NALCO 93033 is a chemical additive used primarily for treating boilers, steam lines, and cooling systems. It acts as an anticorrosive agent, specifically protecting copper components within cooling circuits. For the 2021 period, the Ecolab SDS portal is the official source for the most current Safety Data Sheet (SDS), formerly known as the Material Safety Data Sheet (MSDS). Product Identification and Use Official Name: NALCO 93033.
Primary Application: Used for commissioning new systems, regular maintenance, and topping up water in cooling circuits.
Industry Standards: This product is acceptable for treating systems in food processing areas, provided the treated water or steam does not contact edible products (NSF Category G7). Storage and Shelf Life
Proper handling is critical to maintaining the efficacy and safety of the chemical.
Shelf Life: NALCO 93033 has a shelf life of one year when stored at a maximum temperature of
Storage Group: It is classified under Group A (engine and cooling water treatment products) and should be stored away from acids (Group C) and other incompatible chemicals.
Incompatibility: Avoid contact with aluminum, copper, or brass feeding equipment, as well as materials like rubber, neoprene, and polyurethane. Hazard Identification and Safety Precautions
While the specific 2021 SDS must be requested directly from Nalco Water, general safety standards for similar Nalco cooling additives include: nalco 93033 msds 2021
Potential Hazards: May be corrosive to metals and cause irritation to the skin and eyes.
Protective Equipment (PPE): Users should wear safety goggles, face shields, and chemical-resistant gloves.
Environmental Impact: Many industrial water treatments are toxic to aquatic life; spills must be contained to prevent them from reaching soil or surface water. Regulatory Compliance
The Hazard Communication Standard (HCS) requires that chemical manufacturers provide updated SDS to downstream users. Employers must maintain these records for at least 30 years to comply with OSHA standards. Safety Data Sheets - SDS - MSDS - Ecolab
The NALCO® 93033 Safety Data Sheet (SDS), formerly known as a Material Safety Data Sheet (MSDS), provides critical safety, handling, and regulatory information for this specific chemical product manufactured by Nalco Water, an Ecolab company.
While the full 2021 version is typically distributed directly to customers with product shipments, the following summarizes the standard components and safety expectations for Nalco chemical products based on the Ecolab SDS Database. 1. Product Identification Product Name: NALCO® 93033 Manufacturer: Nalco Water, an Ecolab Company.
Primary Use: Industrial water treatment or process chemical (specific use cases vary by industry application). 2. Hazard Identification
Safety Data Sheets for the 93000-series typically categorize products based on their chemical composition. Common hazard profiles for similar Nalco process chemicals include:
GHS Classification: May range from "Not a hazardous substance" to specific classifications such as "Skin Irritation" or "Eye Irritation." Nalco 93033 is a specialized biocide and cooling
Precautionary Statements: Generally include instructions to wash hands thoroughly after handling and to store in a well-ventilated place. 3. First Aid & Emergency Measures
Standard emergency protocols for Nalco industrial chemicals:
Eye Contact: Immediately flush with plenty of water for at least 15 minutes. Seek medical attention if irritation persists. Skin Contact: Wash off with soap and plenty of water.
Ingestion: Rinse mouth with water. Do not induce vomiting unless directed by medical personnel. Inhalation: Move to fresh air. 4. Handling and Storage
Storage Conditions: Store in suitable, labeled containers. Keep containers tightly closed and protect from freezing to maintain product stability.
Incompatible Materials: Consult the specific SDS section 10; many water treatment chemicals are incompatible with strong acids or oxidizing agents. 5. Regulatory and Environmental Information
TSCA Status: Components are typically listed on the Toxic Substances Control Act (TSCA) inventory.
Environmental Impact: In the event of a spill, prevent material from entering sewers or waterways. Large spills should be contained using absorbent material and reclaimed into salvage drums for proper disposal. How to Obtain the Official 2021 MSDS/SDS
Because chemical formulations and regulatory requirements can change, it is vital to use the most current version. You can request the specific NALCO 93033 SDS through these official channels: What Changed Between 2018 and 2021
Online Search: Use the Ecolab SDS Search Tool by entering the product name or code.
Direct Request: If it is not available online, submit a request via the Nalco Water SDS Request Form.
Customer Support: Contact your local Nalco Sales Representative or call the emergency number listed on your product label for immediate assistance.
Note: NALCO 93033 is typically a water treatment chemical (often a coagulant or flocculant). As of recent regulatory shifts (GHS), many "MSDS" documents are now called "SDS" (Safety Data Sheets). This post addresses that transition while focusing on the 2021 data.
If you are comparing an older MSDS to the 2021 version, look for:
This section was significantly expanded in 2021 due to EPA Safer Choice criteria.
Based on the 2021 GHS classification, NALCO 93033 was classified as:
NALCO 93033 is a specialized industrial water treatment chemical manufactured by Nalco Water, an Ecolab company. In 2021, this product was primarily utilized as a scale inhibitor and deposit control agent within high-pressure boiler systems and cooling water towers. Unlike traditional phosphonate-based treatments, NALCO 93033 was formulated for facilities requiring "low phosphorus" or "non-phosphorus" discharge permits, helping industrial plants meet stringent local environmental effluent regulations.
The 2021 revision of its MSDS (referred to globally as SDS) was critical due to updates in the OSHA Hazard Communication Standard (HCS 2012) aligning with GHS revision 7, which introduced stricter language on chronic aquatic toxicity and specific target organ toxicity (STOT).
