Nalco 77225 is a specialized internal boiler feedwater treatment designed for scale control. It utilizes a combination of a phosphate residual program and Nalco’s proprietary Transport Plus polymer technology to maintain clean boiler surfaces.

As an alkaline, corrosive chemical, managing it requires strict adherence to its Safety Data Sheet (SDS) to prevent injury and equipment damage. Key Hazard Identifications

Nalco 77225 is classified under GHS (Globally Harmonized System) with several critical hazards:

Corrosive to Metals: May cause damage to certain metal containers or equipment.

Health Hazards: It is harmful if swallowed and can cause severe skin burns and irreversible eye damage.

Alkalinity: With a pH of 13.5 (100%), it is highly basic and reacts aggressively with acidic substances. Essential Safety Measures

Handling this product safely requires specific Personal Protective Equipment (PPE) and environmental controls: If you want, I can:

Protective Gear: Operators must wear chemical splash goggles, a full-face shield, and gloves/clothing made of materials impervious to the chemical (e.g., Neoprene, EPDM, or Butyl Rubber).

Ventilation: Ensure adequate general ventilation in areas where the product is used or stored.

Hygiene: Keep an eye wash station and safety shower readily available. Do not eat, drink, or smoke while handling. Physical and Chemical Properties
