Hazard Statements: May be corrosive to metals; harmful if swallowed; causes severe skin burns and eye damage.

Active Ingredients: Contains Potassium Hydroxide (10-30%) and Tetrapotassium Pyrophosphate (10-30%). Emergency Measures

Immediate medical attention is required for skin/eye contact, which necessitates rinsing with water for at least 15 minutes. If swallowed, do not induce vomiting and seek immediate medical help. Physical and Chemical Properties

Appearance: Colorless to light yellow liquid, with a density of 1.46 – 1.50 at 25°C. pH: Extremely alkaline, with a pH of approximately 13.5. Nalco 77225 SDS (GHS) | PDF | Toxicity - Scribd

The latest Safety Data Sheet (SDS) for NALCO 77225 identifies it as a highly alkaline liquid used primarily for internal boiler water treatment. Classified as GHS Category 1 Corrosive, this product requires strict handling protocols due to its potential to cause severe chemical burns and permanent eye damage. Product Overview NALCO 77225

is designed for scale control in boiler feedwater systems. It utilizes a combination of phosphate residual programmes and "Transport Plus" polymer technology to prevent the formation of adherent deposits, which helps maintain boiler efficiency and prevent tube overheating. Chemical Composition & Hazards

The product is a liquid mixture with a distinct ammoniacal odour and a very high pH of 13.5. Its primary hazardous components include:

Potassium Hydroxide (10–30%): A strong base responsible for its corrosive nature. Brief summary — Nalco 77225 Safety Data Sheet (SDS) update

Tetrapotassium Pyrophosphate (10–30%): Used for water softening and scale inhibition. As a GHS Category 1 corrosive, NALCO 77225

causes severe skin burns and eye damage, and is harmful if swallowed. Safety & First Aid Protocols

Due to its high alkalinity, immediate action is required in the event of exposure:

Eye/Skin Contact: Rinse immediately with plenty of water for at least 15 minutes, removing contaminated clothing. Ingestion: Rinse mouth with water; do not induce vomiting.

PPE: Operators must use safety goggles, a full face shield, and chemical-resistant gloves (neoprene or nitrile). Handling and Storage

Compatibility: Safe with stainless steel, polyethylene, and PVC; incompatible with aluminum, copper, brass, or zinc.

Storage: Keep in corrosive-resistant containers below 65°C (149°F) to avoid precipitate formation. Nalco 77225 SDS (GHS) | PDF | Toxicity - Scribd
