2593 Msds: Nalco

Nalco 2593 is a specialized non-oxidizing microbiocide primarily used to control bacteria, algae, and fungi in industrial water systems. Because it is classified as a hazardous chemical, having the Material Safety Data Sheet (MSDS)—now more commonly referred to as the Safety Data Sheet (SDS)—is essential for safe handling and regulatory compliance. What is Nalco 2593?

Nalco 2593 is a liquid biocide formulation designed for industrial cooling towers, closed-loop cooling systems, and air washers. It is often used in food processing facilities for treating boilers and steam lines, provided that the steam or treated water does not come into direct contact with edible products. Chemical Family: Isothiazolinone.

Active Ingredients: Typically contains 5-chloro-2-methyl-4-isothiazolin-3-one and 2-methyl-4-isothiazolin-3-one. Physical State: Liquid. Key Sections of the Nalco 2593 MSDS/SDS nalco 2593 msds

An MSDS provides critical information across several sections to ensure workplace safety. For Nalco 2593, the following sections are of particular importance: 1. Hazard Identification Nalco 2593 is classified as a corrosive material.

Health Hazards: It can cause severe skin burns and permanent eye damage. It is also a known skin sensitizer, meaning repeated exposure can lead to allergic reactions. Stability: Stable under normal conditions

Environmental Hazards: As a biocide, it is highly toxic to aquatic life and must be prevented from entering natural waterways. 2. First Aid Measures In the event of exposure, immediate action is required:

Eye Contact: Rinse immediately with plenty of water for at least 15 minutes, holding eyelids open. Seek urgent medical attention. deposit control agent. Supplier: NALCO Water

Skin Contact: Remove contaminated clothing and wash the skin thoroughly with soap and water.

Ingestion: Do not induce vomiting. Rinse the mouth with water and contact a poison control center immediately. 3. Handling and Storage

Section 10: Stability and Reactivity

• Stability: Stable under normal conditions.
• Conditions to avoid: High temperatures (> 200°F), strong bases, hypochlorite bleaches.
• Hazardous decomposition: Phosphorus oxides, carbon monoxide.

10. Stability and Reactivity

• Stability: Stable under recommended storage conditions.
• Reactivity: Reacts with acids. Sodium nitrite can react with amines to form nitrosamines (potential carcinogens). Contact with strong reducing agents can generate heat.
• Hazardous Decomposition Products: Nitrogen oxides (NOx), Carbon monoxide, Carbon dioxide.

Weaknesses / Gaps in some older MSDS versions

• Some older sheets lacked GHS pictograms (e.g., corrosion icon, exclamation mark).
• May not provide specific biodegradation half-life for phosphonates (proprietary blend).
• No specific OSHA PEL (occupational exposure limit) because low volatility.
