Nalco - 77225 Safety Data Sheet Full [new]

Comprehensive Safety Guide for Nalco 77225 Internal Boiler Treatment

Nalco 77225 is a highly alkaline liquid chemical used for internal boiler feedwater treatment to control scale formation. It utilizes a combination of phosphate residual programs and Transport Plus polymer technology to manage calcium, magnesium, and silica, ensuring efficient boiler operation and preventing tube overheating.

Because this product is classified as a hazardous and corrosive mixture, it is critical to adhere to the guidelines outlined in the Safety Data Sheet (SDS) to ensure workplace safety. 1. Product Identification and Hazards

Nalco 77225 is primarily composed of Tetrapotassium Pyrophosphate (10-30%) and Potassium Hydroxide (10-30%). According to GHS classifications, it presents several significant hazards:

Corrosive to Metals: Category 1—may be corrosive to specific metal types. Acute Toxicity (Oral): Category 4—harmful if swallowed. Skin Corrosion: Category 1A—causes severe skin burns.

Serious Eye Damage: Category 1—causes permanent or irreversible eye damage. 2. Physical and Chemical Properties

Understanding the physical state of the chemical is vital for safe containment and handling: Appearance: Colourless to light yellow liquid. Odour: Strong ammoniacal scent. pH Level: Highly alkaline, typically 13.5 (100%). Flash Point: Does not flash; not flammable or combustible. Solubility: Completely soluble in water. Density: 1.46 - 1.50 at 25°C. 3. Safe Handling and Personal Protection

Given its high alkalinity and corrosive nature, all personnel must use appropriate Personal Protective Equipment (PPE) when handling neat or diluted product:

Eye Protection: Wear chemical splash goggles and a full-face shield to prevent ocular contact. nalco 77225 safety data sheet full

Skin Protection: Use standard chemical-resistant protective clothing and gloves. If skin contact occurs, wash immediately for at least 15 minutes.

Respiratory Protection: Not normally needed under standard conditions, but certified respirators should be used if concentrations exceed established exposure limits.

Engineering Measures: Use an effective exhaust ventilation system to keep air concentrations below occupational standards. 4. First Aid Measures

In the event of accidental exposure, immediate action is required:

Eye Contact: Rinse cautiously with water for at least 15 minutes, removing contact lenses if present. Seek immediate medical attention.

Skin Contact: Remove contaminated clothing immediately and rinse the skin with plenty of water for 15 minutes. Use mild soap if available.

Ingestion: Rinse the mouth with water. Do NOT induce vomiting. Seek emergency medical help immediately.

Inhalation: Move the individual to fresh air and keep them comfortable for breathing. Treat symptomatically. 5. Storage and Compatibility Comprehensive Safety Guide for Nalco 77225 Internal Boiler

Proper storage prevents chemical degradation and accidental reactions:

Conditions: Keep the container tightly closed in a cool, well-ventilated area. The maximum recommended storage temperature is 65°C (149°F); higher temperatures may cause a white precipitate to form. Compatibility:

Compatible Materials: Stainless steel (304/316L), HDPE, PVC, Polypropylene, and PTFE.

Incompatible Materials: Avoid contact with strong acids, aluminium, copper, brass, and zinc.

Shelf Life: Recommended storage limit in unopened containers is 6 months after receipt. 6. Accidental Release and Disposal

Spills must be handled by trained personnel using appropriate PPE:

Containment: Stop the leak if safe to do so. Contain the spill with non-combustible absorbent material (sand, earth, or vermiculite).

Disposal: Dispose of contents and containers at an approved waste disposal plant in accordance with local and national regulations. Nalco 77225 SDS (GHS) | PDF | Toxicity - Scribd Product Name: Nalco 77225 Recommended Use: Microbiocide for
