Joe, a veteran technician at the local utility plant, started his morning shift by reviewing the Safety Data Sheet (SDS) NALCO 77225
. Although he had used it for years to control scale in the facility’s low-pressure boilers, he knew the 2021 guidelines emphasized vigilance. The SDS clearly labeled the product with a signal word. It was classified as: Category 1 Corrosive to Metals : Capable of damaging certain storage materials. Category 1A Skin Corrosion : Capable of causing severe chemical burns. Category 1 Serious Eye Damage : High risk of irreversible eye injury upon contact. Preparing for the Task
Before approaching the chemical feed station, Joe suited up in the required Personal Protective Equipment (PPE) Eye Protection
: Safety goggles and a full-face shield to prevent splashes. Hand Protection
: Chemical-resistant gloves (standard types like Neoprene or Nitrile are often used for such alkaline products). Skin Protection
: A protective apron and standard work clothing to ensure no bare skin was exposed. Joe remembered that NALCO 77225 contains Potassium Hydroxide (10-30%) and Tetrapotassium Pyrophosphate (10-30%), making it highly alkaline with a pH of 13.5 Safe Handling and Storage
Joe checked the storage area to ensure the containers were tightly closed and kept away from strong acids
, as the SDS warned that contact could cause dangerous reactions. He also verified the room temperature was below 65°C (149°F)
to prevent the formation of white precipitates in the liquid. The Emergency Protocol While Joe worked safely, he always kept the First Aid Measures in mind, just in case: Eye Contact
: Immediately flush with water for at least 15 minutes and seek medical attention instantly. Skin Contact
: Wash off immediately with plenty of water for 15 minutes; remove any contaminated clothing. : Rinse mouth with water but do NOT induce vomiting . Seek medical help immediately.
By following the 2021 SDS protocols, Joe ensured the boiler remained scale-free while keeping himself and his teammates safe from the hazards of industrial chemistry. specific compatibility

Understanding the Nalco 77225 Safety Data Sheet (SDS) is essential for ensuring the safe handling, storage, and application of this specialized water treatment chemical. Nalco 77225 is primarily used as an internal boiler treatment designed for scale control in high-pressure systems. Product Overview and Application
Nalco 77225 is an alkaline liquid formulation that utilizes a blend of complex phosphates and proprietary Transport Plus polymer technology.
Scale Control: It prevents the formation of adherent scale by reacting with calcium and magnesium, keeping these minerals in a non-adherent sludge form that can be easily removed via blowdown.
System Suitability: It is typically recommended for boilers operating at pressures up to 40 bar (approximately 580 psi).
Regulatory Compliance: When used according to guidelines, it complies with FDA regulations (21 CFR 173.310) for boiler water additives where steam may contact food. Hazard Identification (GHS Classification)
According to the SDS, Nalco 77225 is classified as a hazardous substance with the following primary risks:
Corrosive to Metals: Category 1 – May be corrosive to metals like aluminium, copper, and zinc. Skin Corrosion: Category 1A – Causes severe skin burns.
Serious Eye Damage: Category 1 – Causes permanent eye damage upon contact. Acute Oral Toxicity: Category 4 – Harmful if swallowed. Chemical Composition The active hazardous ingredients typically include:
Potassium Hydroxide (10–30%): Provides alkalinity to maintain proper pH levels.
Tetrapotassium Pyrophosphate (10–30%): Acts as a scale inhibitor and sequestering agent. Safe Handling and Personal Protective Equipment (PPE)
Due to its high pH (typically >13), strict safety measures must be followed:
Eye Protection: Wear chemical splash goggles and a full face shield.
Skin Protection: Use chemical-resistant gloves (neoprene or nitrile) and protective clothing.
Respiratory Protection: Not required under normal use with adequate ventilation, but should be used if mist or vapours are generated.
Hygiene: Always provide facilities for quick drenching or flushing of eyes and body in the immediate work area. Emergency and First Aid Measures
Eye Contact: Flush immediately with water for at least 15 minutes, removing contact lenses if present. Seek medical attention immediately.
Skin Contact: Remove contaminated clothing and wash skin with plenty of water for 15 minutes. Use mild soap if available.
Ingestion: Do NOT induce vomiting. Rinse the mouth with water and seek immediate medical help.
Inhalation: Move the person to fresh air. Treat symptomatically. Storage and Compatibility
Temperature Limits: Store at temperatures between 10°C and 65°C (50°F to 149°F). Storing above this range can cause the formation of a white precipitate.
Shelf Life: Generally 6 months to 2 years depending on local storage conditions. Materials Compatibility: Compatible: Stainless steel, PE, PP, PVC, and Teflon.
Incompatible: Strong acids, aluminium, copper, brass, and zinc.
