Isopropyl alcohol, also known as isopropanol or 2-propanol, is a colorless, flammable, and volatile liquid with a characteristic odor. It is widely used as a solvent, a cleaning agent, and a disinfectant in various industries, including healthcare, pharmaceuticals, and manufacturing. The Material Safety Data Sheet (MSDS) for isopropyl alcohol provides critical information on its safe handling, use, storage, and disposal.
Chemical Properties and Identification
Isopropyl alcohol has a molecular formula of C3H8O and a molecular weight of 60.10 g/mol. It has a boiling point of 82.5°C and a melting point of -89.5°C. Its density is 0.786 g/cm3 at 20°C, and it is miscible with water, ethanol, and ether. Isopropyl alcohol is a highly flammable liquid with a flash point of 12°C and an autoignition temperature of 399°C.
Hazards and Risks
The MSDS for isopropyl alcohol highlights several hazards and risks associated with its handling and use. These include:
- Flammability: Isopropyl alcohol is highly flammable and can ignite easily, posing a significant fire hazard.
- Eye and skin irritation: Isopropyl alcohol can cause irritation, redness, and dryness of the eyes and skin upon contact.
- Respiratory problems: Inhaling isopropyl alcohol vapors can cause respiratory irritation, coughing, and shortness of breath.
- Neurological effects: Prolonged exposure to isopropyl alcohol can cause dizziness, headaches, and nausea.

Handling and Storage
To ensure safe handling and storage of isopropyl alcohol, the following precautions should be taken:
Isopropyl alcohol should be stored in a well-ventilated area, away from heat sources, sparks, and open flames. It should be kept in tightly closed containers, labeled with warning signs, and protected from physical damage. The storage area should be equipped with fire extinguishers and emergency showers.
Emergency Procedures
In case of an emergency, the following procedures should be followed:
- Fire: Use dry chemical, carbon dioxide, or foam extinguishers to put out fires involving isopropyl alcohol.
- Spill: Contain spills immediately, and clean up with absorbent materials, such as sand or vermiculite.
- Exposure: Wash affected areas with soap and water, and seek medical attention if irritation or other symptoms persist.
What are the recommended personal protective equipment (PPE) for handling isopropyl alcohol?
+The recommended PPE for handling isopropyl alcohol includes gloves, goggles, face masks, and protective clothing to minimize skin and eye contact and prevent inhalation of vapors.
What are the first aid measures for isopropyl alcohol exposure?
+In case of skin contact, wash the affected area with soap and water. For eye exposure, flush with water, and seek medical attention if irritation persists. If inhaled, remove the person to fresh air, and provide artificial respiration if necessary.
In conclusion, isopropyl alcohol is a widely used chemical with various applications, but it also poses significant hazards and risks. By following the guidelines outlined in the MSDS, handling and storing isopropyl alcohol safely, and taking necessary precautions, the risks associated with its use can be minimized, ensuring a safe working environment for individuals and preventing accidents.
