1. Identification

Product: Flux-Off No Clean Extra, an aerosol flux remover for industrial/professional use.

Supplier: Chemtronics, Kennesaw, GA, USA. Emergency contact via Chemtrec 1-800-424-9300 (24/7).

Product Code: ES888B-B.

2. Hazards Identification

The product is classified as an extremely flammable aerosol (Category 1), contains compressed gas, and causes serious eye irritation (Category 2A). The signal word is "Danger." Key hazards include explosion risk if heated and serious eye irritation. Precautions involve avoiding heat, sparks, and flames, wearing eye/face protection, not piercing or burning the container, and washing hands after use.

3. Composition / Ingredients

Main hazardous ingredients are Acetone (10-25%) and (2-methoxymethylethoxy)propanol (≤5%). No other significant hazardous components reported.

4. First Aid Measures

• Eye Contact: Rinse with water for 10+ minutes, remove contact lenses, seek medical help if irritation persists.
• Skin Contact: Flush with water, remove contaminated clothing, seek medical attention if symptoms occur.
• Inhalation: Move to fresh air, provide artificial respiration if needed, seek medical attention if symptoms persist.
• Ingestion: Do not induce vomiting unless directed, rinse mouth, seek immediate medical attention.

Symptoms include eye and skin irritation, respiratory irritation, and possible CNS depression.

5. Fire-Fighting Measures

The aerosol is extremely flammable with explosion risk if heated. Firefighters should use self-contained breathing apparatus (SCBA) and full protective gear. Suitable extinguishing media depend on surrounding fire. Containers should be cooled with water spray and removed if safe.

6. Accidental Release Measures

Evacuate area, avoid ignition sources, wear appropriate PPE, and avoid inhaling vapors. Prevent environmental contamination by containing spills with inert absorbents (sand, earth, vermiculite). Dispose of waste per regulations using licensed contractors.

7. Handling and Storage

Handling: Use with adequate ventilation, avoid eye/skin contact, do not pierce or burn containers, avoid vapor inhalation, and use explosion-proof equipment.

Storage: Store in cool, dry, ventilated area away from sunlight, ignition sources, and temperatures above 50°C. Keep away from incompatible materials and food.

Hygiene: No eating, drinking, or smoking in handling areas; wash hands before breaks and after work.

8. Exposure Controls / Personal Protection

Exposure Limits: Acetone - ACGIH TLV TWA 250 ppm, STEL 500 ppm; OSHA PEL TWA 1000 ppm. (2-methoxymethylethoxy)propanol - ACGIH TLV TWA 100 ppm, STEL 150 ppm; OSHA PEL TWA 100 ppm.

Engineering Controls: Use local exhaust or process enclosures with explosion-proof ventilation to maintain exposure below limits.

Personal Protective Equipment: Chemical splash goggles, chemical-resistant gloves, anti-static protective clothing if ignition risk, and respirators if ventilation is inadequate.

Environmental Controls: Ensure emissions comply with regulations; use fume scrubbers or filters if needed.
