A Safety Data Sheet (SDS), formerly known as a Material Safety Data Sheet (MSDS), is a detailed information document prepared by the manufacturer or importer of a hazardous chemical that describes the physical and chemical properties, physical and health hazards, precautions for safe handling and use, emergency and first-aid procedures, and control measures, among other things.
Below, I’ve provided an overview of the safety data for methanol, summarized in a blog-style format for better comprehension:
Safety Data Sheet Overview Methanol
Introduction
Methanol, commonly referred to as wood alcohol, is a simple alcohol with the chemical formula CH₃OH. Due to its widespread applications, it’s essential to understand the potential risks and safety protocols when handling or coming in contact with this chemical.
1. Identification
- Chemical Name: Methanol
- Synonyms: Wood alcohol, methyl alcohol, carbinol
- Chemical Formula: CH₃OH
2. Hazards Identification
- Physical State: Liquid
- Odor: Slight alcoholic odor
- Main Hazards: Flammable, toxic if ingested, inhaled, or absorbed through the skin.
3. Composition/Information on Ingredients
Methanol is often sold in its pure form, but depending on the application, it may be mixed with other chemicals.
4. First-aid Measures
- Inhalation: Move victim to fresh air. If not breathing, perform artificial respiration. Seek medical attention immediately.
- Ingestion: Do NOT induce vomiting. Rinse mouth, then drink one or two large glasses of water. Seek emergency medical attention immediately.
- Skin: Remove contaminated clothing. Wash skin with plenty of water. If irritation persists, seek medical advice.
- Eyes: Rinse with plenty of water for at least 15 minutes. If irritation persists, consult a physician.
5. Fire-fighting Measures
- Extinguishing Media: Use alcohol-resistant foam, carbon dioxide, or dry chemical.
- Special Firefighting Procedures: Use water to cool containers exposed to fire. Firefighters should wear self-contained breathing apparatus.
6. Accidental Release Measures
Spills should be contained and collected, then disposed of according to local regulations. Prevent entry into waterways, sewers, or confined areas.
7. Handling and Storage
- Handling: Use with adequate ventilation. Avoid breathing vapor. Avoid contact with eyes, skin, and clothing. Use non-sparking tools.
- Storage: Store in a cool, dry, well-ventilated area, away from open flames and incompatible materials.
8. Exposure Controls/Personal Protection
- Engineering Controls: Use with adequate ventilation. Ensure that eyewash stations and safety showers are close to the workstation.
- Personal Protective Equipment (PPE): Wear protective gloves, safety goggles, and a suitable respirator if required.
9. Physical and Chemical Properties
- Boiling Point: 64.7°C (148.5°F)
- Melting Point: -97.7°C (-143.8°F)
- Specific Gravity: 0.791 at 20°C
- Solubility in Water: Completely soluble
10. Stability and Reactivity
Methanol is stable under recommended storage conditions. It reacts with strong oxidizers and can form explosive mixtures in air.
Conclusion
Methanol is a versatile solvent with many applications, but it’s essential to handle it with care due to its flammable and toxic nature. Proper knowledge of its hazards and adherence to safety protocols can minimize the risks associated with its use.
