The product itself is . However, when involved in a fire, it may evolve oxides of carbon (COx) and oxides of nitrogen (NOx) , which are hazardous and can be toxic. A critical safety consideration is that if the product is allowed to dry, the sodium nitrite component acts as an oxidizing agent and can initiate the combustion of other materials.

Understanding the —now standardized as the Safety Data Sheet (SDS) —is critical for any personnel handling this chemical to ensure workplace safety and environmental compliance. Chemical Composition and Hazards

According to the Nalcool 2000 Safety Data Sheet , the following precautions must be observed during use: : Eyes : Wear chemical-grade goggles or a face shield.

: Store in a cool, dry, and well-ventilated area in the original labeled container. Keep it tightly closed and separate from acids , organics, and reducing agents to prevent hazardous reactions. Emergency and First Aid Measures

Varies across studies, generally ranging from 2,000 mg/kg to 3,362 mg/kg in rat studies.

Regulations require that the SDS be less than 5 years old. To get the official current version:

Nalco 2000 is a commercial/industrial chemical product family used for water treatment and process control (scale/corrosion inhibitors, dispersants, biocides and related chemistries). Exact composition and hazards depend on the specific Nalco 2000 formulation; “Nalco 2000” may be a trade name or part of a product code and requires the manufacturer’s Safety Data Sheet (SDS/MSDS) for precise information.

Since 2011, Nalco has been a wholly-owned subsidiary of , operating globally as Nalco Water, an Ecolab company .

High toxicity. Large exposures can be fatal and may cause methemoglobinemia (a blood disorder that prevents oxygen from reaching tissues), resulting in cyanosis.
