The storage conditions of dichloromethane solvent are critical to its stability and safety and are detailed below:
Temperature control
- Storage temperature: dichloromethane solvent should be stored at room temperature, but the temperature should not normally exceed 35. Excessive temperatures may lead to an increase in its pressure and increased volatilization, compromising the safety of storage. Excessively low temperatures should also be avoided to prevent rupture of the container or freezing of the liquid.
- Temperature Stability: The room temperature of the storage container should be kept as stable as possible to minimize the effects of temperature fluctuations on dcm solvent.
Shelter from Light and Ventilation
- Shelter from Light Storage: dcm solvent should be avoided from direct exposure to sunlight or strong light, as light may cause chemical reactions or degrade its quality. Therefore, storage containers should be placed in a cool, dry and light protected area.
- Well-ventilated: Storage areas should be equipped with effective ventilation systems to maintain air flow and reduce solvent concentrations. Ventilation systems should be inspected and cleaned regularly to ensure proper functioning.
Container and Sealing
- Container Selection: Containers for storing dcm should be metal or other containers with sufficient corrosion resistance and structural strength to prevent leakage of the container due to corrosion.
- Sealing check: The sealing and integrity of the container should be checked regularly to ensure that there is no leakage. If leakage is found, immediate measures should be taken to repair it.
Fire and explosion prevention
- Keep away from ignition sources: dichloromethane liquid is a flammable and explosive substance, so it should be kept away from open flames, high heat sources and static electricity generating equipment.
- Fire prevention measures: The storage area should be equipped with appropriate fire fighting equipment, such as fire extinguishers, fire sand, etc., and their effectiveness should be checked regularly.
Safe operation and protection
- personal protection: When handling and storing dichloromethane, operators should wear appropriate protective equipment, including chemical protective gloves, goggles, protective clothing and respirators to prevent direct contact with dichloromethane.
- Safe Handling: When accessing Methylene Chloride(dcm), it should be handled with care to avoid splashing on skin, eyes or clothing. Containers should be sealed and placed in a designated location promptly after use.
Other Precautions
- Avoid Mixed Storage: Methylene Chloride(dcm) should be kept away from oxidizers, alkalis and flammable substances to prevent dangerous chemical reactions.
- Regular inspection: The storage area should be inspected regularly to ensure that the storage conditions are in accordance with the regulations and any problems found should be dealt with in time.
