Understanding the NALCO 93033 MSDS: Safety, Handling, and Compliance

Section 5: Firefighting Measures

• Suitable extinguishing media: Use water spray, alcohol-resistant foam, dry chemical, or carbon dioxide.
• Specific hazards: May release toxic fumes (oxides of phosphorus, carbon monoxide) when heated to decomposition.
• Special protective equipment for firefighters: Self-contained breathing apparatus (SCBA) and full protective gear.

Section 6: Accidental Release Measures

• Personal precautions: Evacuate area. Use PPE (acid-resistant gloves, goggles, apron, rubber boots).
• Environmental precautions: Prevent entry into sewers, waterways, or groundwater.
• Methods for cleaning up: Neutralize with lime, soda ash, or sodium bicarbonate. Absorb with inert material (sand, vermiculite) and place in designated chemical waste containers.

Section 11: Toxicological Information

• Acute toxicity: Low oral toxicity (LD50 >2000 mg/kg, typical), but primary hazard is corrosive action.
• Skin corrosion: Severe burns.
• Eye damage: Irreversible damage.
• Sensitization: Unlikely.

Section 12: Ecological Information

• Ecotoxicology: Moderately toxic to fish and aquatic invertebrates (based on phosphonate content). Avoid large-scale environmental release.
• Persistence and degradability: Phosphonates are generally persistent but can hydrolyze.
• Bioaccumulation potential: Low.

4. Why This SDS Matters for Your Facility

Using NALCO 93033 without an up-to-date SDS exposes your operation to:

• OSHA/EPA fines (up to $14,502 per violation per day in 2025).
• Worker injury (corneal burns from splashes are the #1 reported incident).
• Environmental penalties for improper discharge (can exceed $50,000 per event under Clean Water Act).
