Signal Word: WARNING
Hazard Statements (H-Statements):
The MSDS (or SDS) is not just a paper requirement from OSHA or the EU’s REACH regulation. It is a life-saving tool. For Nalco 2000, the MSDS highlights three critical risk areas:
Ignoring the MSDS can lead to chemical burns, respiratory failure, or severe environmental fines.
This is the "chemical formula" section. For Nalco 2000, expect:
Note: The exact percentage is often listed as a range to protect trade secrets, but the hazards are clearly defined.
Nalco 2000 (often marketed as Nalcool 2000) is a liquid engine corrosion inhibitor and scale suppressant. According to its Safety Data Sheet (SDS), it is primarily used to protect cast iron diesel engine cooling systems. 1. Hazard Identification Classification: Classified as Harmful and Irritant. Key Warnings: Skin & Eyes: Causes moderate to serious irritation.
Ingestion: Harmful or fatal if swallowed in large doses. It can cause methemoglobinemia (blood system disorder), which may lead to cyanosis (blue skin) or death.
Environment: Toxic to fish and harmful to aquatic organisms. SAFETY DATA SHEET NALCOOL® 2000
Understanding the MSDS for NALCOOL 2000: A Comprehensive Safety and Application Guide msds nalco 2000
The NALCOOL 2000 Safety Data Sheet (SDS), formerly known as a Material Safety Data Sheet (MSDS), provides critical information for the safe handling, storage, and application of this specialized engine cooling treatment. Manufactured by companies like Nalco Water (an Ecolab company) and Wilhelmsen, NALCOOL 2000 is a nitrite-based corrosion inhibitor designed specifically for closed cooling systems, particularly in diesel engines. 1. Product Identification and Core Hazards
NALCOOL 2000 is primarily classified as an irritant and harmful substance. It is a dark red liquid with a slight organic odour, featuring a high pH (typically 11.1–11.8), making it mildly alkaline. Primary Hazards identified in the SDS:
Skin and Eye Irritation: Direct contact can cause redness, pain, and moderate to serious irritation.
Ingestion Toxicity: Harmful if swallowed. It contains sodium nitrite, which can lead to methemoglobinemia, a condition that reduces the blood's ability to carry oxygen, potentially causing cyanosis or death.
Aquatic Toxicity: The product is harmful to aquatic life; spills must be contained to prevent environmental damage. 2. Chemical Composition
The effectiveness of NALCOOL 2000 as a corrosion inhibitor comes from its specific chemical blend: SAFETY DATA SHEET NALCOOL 2000
This guide summarizes the Safety Data Sheet (SDS) for Nalco 2000 (also known as Nalcool 2000), a corrosion inhibitor and scale suppressant used primarily in closed-loop cooling systems, such as diesel engines. 1. Product Identification & Composition
Nalco 2000 is a dark red, odorless liquid. It is alkaline, with a pH typically between 11.1 and 11.8. Key Active Ingredients:
Sodium Nitrite: Acts as a corrosion inhibitor but is toxic if ingested.
Sodium Tetraborate & Sodium Metasilicate: Provide alkalinity and further corrosion protection.
Sodium Mercaptobenzothiazole: An additional additive for metal protection. 2. Hazard Identification Nalco 2000 is classified as Harmful and an Irritant. SAFETY DATA SHEET NALCOOL® 2000 (Cooling Water Corrosion & Scale Inhibitor) Under the
The NALCOOL 2000 (also known as NALFLEET 2000) Safety Data Sheet (SDS) identifies it as a liquid diesel engine corrosion inhibitor and scale suppressant used primarily in closed cooling systems. It is classified as a hazardous substance, primarily posing risks of skin and eye irritation and severe internal damage if swallowed. 1. Key Hazards & Safety Information
According to Safety Data Sheets for NALCOOL 2000, the product carries several critical health warnings:
Health Risks: Causes skin irritation and serious eye irritation.
Ingestion Danger: Harmful or even fatal if swallowed in large quantities. It contains Sodium Nitrite, which can cause methemoglobinemia (a blood disorder reducing oxygen transport).
Environmental Impact: Classified as harmful to aquatic organisms.
Personal Protection: Recommended Personal Protective Equipment (PPE) includes chemical-resistant gloves and safety goggles. 2. Physical and Chemical Properties Appearance Red, odorless liquid pH (100%) 11.1 – 11.8 (Alkaline) Specific Gravity 1.12 – 1.16 @ 60°F Solubility Completely soluble in water Freezing Point
-29°C (-20°F); becomes "mushy" at -10°C but is usable after thawing 3. Composition & Ingredients
The formula is a mixture of water and inorganic salts, typically including: Sodium Nitrite: Primary corrosion inhibitor. Sodium Tetraborate (Borate): Used for pH buffering. Sodium Metasilicate: Provides metal protection. 4. Usage & Benefits Nalco 2000 is designed for heavy-duty diesel engines to: SAFETY DATA SHEET NALCOOL® 2000
Nalco 2000 (often referred to as Nalcool 2000) is a liquid chemical treatment specifically designed as a corrosion inhibitor for closed cooling systems, particularly in diesel engines. It functions by forming a protective film on metal surfaces to prevent cavitation, electrolysis, and scale buildup. 1. Hazardous Composition
According to official Safety Data Sheets (SDS/MSDS), the product contains several hazardous ingredients: Sodium Nitrite: The primary active corrosion inhibitor. Sodium Tetraborate: Used for pH buffering.
Sodium Metasilicate: Assists in protecting aluminum and other metal surfaces. Sodium Nitrate: Often included in older formulations. 2. Health Hazards & Safety Ignoring the MSDS can lead to chemical burns,
The product is classified as Harmful and an Irritant. Key health risks include:
Eye & Skin Contact: Causes moderate to serious irritation. Prolonged skin contact can lead to sensitization.
Ingestion: High toxicity. Large exposures can be fatal and may cause methemoglobinemia (a blood disorder that prevents oxygen from reaching tissues), resulting in cyanosis.
Chronic Exposure: Repeated ingestion of small amounts may cause low blood pressure, headaches, and potential organ damage. 3. First Aid Measures
If exposure occurs, immediate action is required according to the Nalcool 2000 SDS: NALCOOL® 2000
Before analyzing the safety sheet, understanding the chemical identity is crucial. Nalco 2000 is typically described as a liquid cationic organic polymer – specifically a polyamine or polyDADMAC type coagulant. Unlike inorganic coagulants (like alum or ferric chloride), Nalco 2000 works by neutralizing the negative charge of suspended particles and promoting floc formation.
