Every employee who handles Nalco 8506 Plus must be trained annually on:
According to the most recent Nalco 8506 Plus SDS, this product is classified as a Hazardous Chemical.
Environmental Warning: Do not flush into surface water or sanitary sewer system. The phosphonate content can cause eutrophication (algae blooms) in natural waters, and the low pH is acutely toxic to aquatic life.
Product Name: Nalco 8506 Plus
Manufacturer: Nalco Water (An Ecolab Company)
Typical Use: Industrial water treatment; specifically formulated as a scale and deposit control agent for cooling water systems, boilers, or reverse osmosis (RO) units. It is a liquid polymer-based inhibitor designed to prevent mineral scale (calcium carbonate, calcium sulfate, etc.) and disperse foulants.
The Nalco 8506 Plus MSDS is not a document to be stored in a dusty binder in the maintenance shed. It is a living operational manual. For any facility using this effective corrosion inhibitor, the following actions are non-negotiable:
By respecting the chemistry outlined in the Safety Data Sheet, you can safely leverage the performance benefits of Nalco 8506 Plus—protecting both your cooling water system and, more importantly, your workforce.
Always download the most recent SDS from the Ecolab / Nalco Water website or request it from your supplier, as formulations and regulatory classifications can change.

The following guide summarizes the safety and handling requirements typically found in its Material Safety Data Sheet (MSDS) or Safety Data Sheet (SDS). 1. Critical Safety Hazards Eyes: Causes serious eye damage upon contact.
Skin/Inhalation: Under normal use, health injuries are generally not known or expected, though standard precautions should always be followed.
Environmental: While specific toxicity for this blend varies by region, biodetergents of this type can impact aquatic life; always prevent concentrated product from entering storm drains or natural waterways. 2. Recommended Personal Protective Equipment (PPE)
Eye Protection: Chemical splash goggles or a full face shield must be worn when handling neat (undiluted) product.
Skin Protection: Wear rubber gloves and protective work clothing.
Respiratory: Usually not required under normal conditions; use in well-ventilated areas. 3. First Aid Measures
Eye Contact: Immediately flush with water for at least 15 minutes, lifting eyelids occasionally. Seek medical attention immediately.
Skin Contact: Flush with plenty of water. Remove contaminated clothing and wash before reuse. Every employee who handles Nalco 8506 Plus must
Ingestion: Rinse mouth. Do not induce vomiting unless directed by medical personnel. Call a poison center if you feel unwell. Inhalation: Move the person to fresh air. 4. Handling and Compatibility
Materials to Use: Storage and application equipment (pumps, lines, tanks) should be made of PVC, PE, Teflon, or Stainless Steel.
Materials to Avoid: Do not use Aluminum, Brass, or Carbon Steel for storage or handling of the neat product.
Storage: Store in a cool, well-ventilated place. Keep containers tightly closed when not in use. 5. Spills and Disposal
Containment: Use inert absorbent material (like sand or earth) to soak up spills.
Disposal: Dispose of in accordance with local and national regulations. This product is acceptable for use in food processing areas under NSF Registration G5 and G7 (for cooling and retort water) provided there is no direct food contact.
You can verify current registration status on the NSF White Book or contact Nalco Water directly for the official, most recent SDS document. NALCO 8506 PLUS Safety Data Sheet | PDF | Toxicity - Scribd
Many maintenance teams view MSDS documents as regulatory paperwork. That’s a dangerous mindset. For NALCO 8506 Plus specifically, the MSDS tells you two critical things: Product Name: Nalco 8506 Plus Manufacturer: Nalco Water
Additionally, OSHA’s Hazard Communication Standard (29 CFR 1910.1200) requires that all employees who work with or near this chemical have access to the MSDS and proper training.
While exact proprietary percentages are not always disclosed, an MSDS for a product like Nalco 8506 Plus will list:
| Chemical Name | CAS Number | Typical % (range) | Role | |---------------|------------|-------------------|-------| | Sodium dichloro-s-triazinetrione (dihydrate) | 51580-86-0 | 25–40% | Active biocide | | Sodium carbonate | 497-19-8 | 5–15% | pH stabilizer | | Sodium sulfate | 7757-82-6 | 1–5% | Processing aid | | Water | 7732-18-5 | Balance | Carrier |
(Note: Always check your specific lot’s SDS, as Ecolab/Nalco may adjust formulas.)
Exposure Limits (as per MSDS):
While the exact proprietary formula is confidential, typical components of Nalco 8500-series products include:
Note: The MSDS will state that specific chemical identity is withheld as a trade secret. It does not typically contain heavy metals (e.g., no zinc, chromium) but is often classified as "low environmental toxicity."
