# Material Safety Data Sheet (MSDS) for HYE-CLEAN SLIME-AWAY

## Product and Company Identification:
- Chemical Product: HYE-CLEAN SLIME-AWAY
- Common Name: Algaecide / Bactericide
- TSCA/CAS No.: This is a mixture, so no single CAS number; components include Copper sulfate pentahydrate (7758-99-8) and Sulfuric acid (7664-93-9).
- Manufacturer: CMR Hydrology Division, Fresno, CA 93745-5000

## Emergency Contact Information:
- Emergency Telephone (Days): (559) 499-2100
- Emergency Telephone (Evenings): (559) 994-9144
- CHEMTREC (24-Hour Emergency Number): (800) 424-9300
- EPA National Response Center: (800) 424-8802

## Hazardous Ingredients:
| Chemical | CAS No. | % | TLV/PEL (lbs) |
| --- | --- | --- | --- |
| Copper sulfate pentahydrate | 7758-99-8 | 19-21% (Contributing copper sulfate) | 1.0 mg/m³ (Dust/mist as copper) |
| Sulfuric acid | 7664-93-9 | 10.75-13.5% | 0.2 mg/m³ |

## Overview:
HYE-CLEAN SLIME-AWAY is a clear blue liquid with a mild odor. It is corrosive to eyes and skin, and at elevated temperatures, it will decompose, generating oxides of sulfur. It should be kept away from strong bases, reducing agents, and oxidizers. Due to its pH-lowering effect and metal/salt constituents, it must not be discharged into streams or water bodies.

Health: 2 (Moderate)
Reactivity: 1 (Slight)
Flammability: 0 (Noncombustible)
Environmental Hazard: 1 (Slight)

## First Aid:
### Eyes:
- Rinse slowly and gently with water for 15-20 minutes. Remove contact lenses if present after the first 5 minutes. Call a poison control center or doctor for advice.

### Skin:
- Remove contaminated clothing. Rinse skin immediately with plenty of water for 15-20 minutes. Seek medical advice.

### Ingestion:
- Sip a glass of water if able to swallow. Do not induce vomiting unless advised by poison control. Do not give anything by mouth to an unconscious person. Call a poison control center or doctor immediately.

### Inhalation:
- Move the affected person to fresh air. If not breathing, administer artificial respiration and call 911 or an ambulance. Seek medical advice.

## Fire and Explosion Hazards:
- Flash Point: Not available.
- Flammability Classification: Noncombustible.
- Hazardous Products of Combustion: May produce oxides of sulfur and, at elevated temperatures, react with metals to generate hydrogen gas, which can form an explosive mixture with air.
- Special Firefighting Procedures: Wear MSHA/NIOSH approved positive pressure, self-contained breathing apparatus.

## Spills and Leaks:
### Containment and Cleanup:
- Flush spills with water into a retaining area or container. Prevent discharge into drinking water sources or streams. Evacuate unnecessary personnel and isolate the hazard area.
- Neutralize solution with sodium bicarbonate or fertilizer-grade lime and dispose of according to local regulations.

## Storage and Handling:
### Storage:
- Store in a cool, well-ventilated place. Avoid storage in excessive heat and do not stack pallets more than two high.
- Do not store near food or feeds, and avoid using steel, galvanized, or nylon equipment.

### Transfer Equipment:
- Use chemical-resistant plastic or stainless steel tanks for transfers. Do not use with sensitive materials or equipment.

### Personal Protective Equipment (PPE):
- Eyes: Wear protective eyewear (goggles, face shield, or safety glasses).
- Skin: Long-sleeved shirts, long pants, shoes, and socks; chemical-resistant gloves.
- Respiratory: Ventilation or a NIOSH/MSHA approved air purifying respirator with an acid gas cartridge may be required in certain circumstances.

## Physical and Chemical Data:
- Appearance: Clear blue liquid
- Odor: Mild
- pH: 1.0
- Vapor Pressure: 0.1 mm at 68°F
- Boiling Point: 220°F
- Density: 9.6-10.0 lbs./gal.

## Stability and Reactivity:
- Stable under normal conditions. Avoid mixing with strong bases, reducing agents, and oxidizers; incompatibility with most metals may result in hydrogen gas production, forming an explosive mixture with air.

## Potential Health Effects:
- Acute Exposure: Corrosive to eyes and skin; inhalation can cause respiratory irritation. Ingestion is highly corrosive and can lead to severe internal damage.
- Chronic Exposure: Systemic toxicity may occur from continued overexposure.

## Ecological Information:
- Algal/Lemna Growth Inhibition: Not known.
- Toxicity to Fish and Invertebrates: Keep out of water bodies due to pH lowering and metal/salt constituents.
- Toxicity to Plants: Unknown.
- Toxicity in Birds: Unknown.

## Disposal:
- Do not discharge into lakes, streams, ponds, estuaries, oceans, or other waters. Dispose of according to local, state, and federal regulations.
