Section 11: Toxicological Information
- Acute oral toxicity (LD₅₀, rat): Estimated 800–1200 mg/kg (Harmful).
- Skin corrosion: Causes irreversible damage after 1–4 minutes contact.
- Eye damage: Severe corneal injury.
- Sensitization: Not known to be a skin sensitizer, but repeated exposure can cause chlorine rash.
- Chronic effects: Prolonged inhalation of dust may cause respiratory irritation and tooth erosion (acidic breakdown).

Section 8: Exposure Controls / Personal Protection
8. Exposure Controls and Personal Protection (PPE)
- Respiratory Protection: If engineering controls (ventilation) are not sufficient to maintain exposure below occupational exposure limits, use a NIOSH-approved respirator with an organic vapor cartridge or a supplied-air respirator.
- Eye Protection: Chemical safety goggles are mandatory. A face shield is recommended when handling open containers or during transfer operations.
- Skin Protection: Wear chemical-resistant gloves (typically Nitrile, Butyl, or Neoprene depending on the exact solvent concentration). Wear long-sleeved shirts and long pants, or a full chemical suit for heavy exposure risk.
- Hygiene: Emergency eyewash stations and safety showers must be accessible in the immediate work area.

Section 1: Identification – What is Nalco 8506 Plus?
Product Name: Nalco® 8506 Plus
Manufacturer: Nalco Water, an Ecolab Company
Common Uses: Oxidizing microbiocide for cooling towers, industrial recirculating water, and pulp/paper mill systems. It controls slime-forming bacteria, Legionella, and biofilms. Executive summary Nalco 8506 Plus is a commercial
Key Chemical Identity: Nalco 8506 Plus typically contains a stabilized solution of Sodium Dichloro-s-triazinetrione or a related chlorine-donor compound. Unlike uns Table stabilized chlorines, this product offers extended residual efficacy. Section 4: First-Aid Measures – Immediate Action Required
Why the MSDS is Mandatory: Without the MSDS, you do not know the specific concentration, the exact stabilizing agents, or the correct personal protective equipment (PPE). A generic chlorine MSDS is insufficient.
Environmental Precautions:
- Do not allow entry into drains, sewers, or surface water. Very toxic to fish and aquatic invertebrates.
- Notify environmental authorities if any waterway contamination occurs.
