Dry ice requires careful handling during car transport due to its extreme cold temperature (-109.3°F/-78.5°C) and sublimation into carbon dioxide gas. Here's how to safely transport dry ice in your vehicle:

Ventilation Requirements

• Keep windows slightly open while driving
• Never transport dry ice in a completely sealed vehicle
• Use air conditioning in recirculation mode
• Take frequent breaks to air out the vehicle

Container Selection

• Use a well-insulated cooler or styrofoam container
• Never use an airtight container that could burst
• Ensure container has small ventilation holes
• Secure container to prevent tipping during transit

Safe Handling Practices

• Always wear thick, insulated gloves
• Use tongs or a scoop to handle dry ice
• Never touch dry ice with bare hands
• Keep dry ice away from face and skin
• Store container in trunk when possible

Transportation Guidelines

• Place container where air can circulate
• Don't store in passenger compartment if possible
• Keep away from vehicle's ventilation system
• Monitor for signs of CO2 buildup (dizziness, headache)

Storage Duration Tips

• Plan for 5-10 pounds of sublimation per day
• Consider outside temperature impact
• Use thicker insulation for longer trips
• Check dry ice levels periodically

Disposal Safety

• Allow to sublimate in well-ventilated area
• Never dispose in sink, toilet, or enclosed space
• Don't leave in parking lots or public areas
• Keep away from children and pets

Legal Considerations

• Check local transportation regulations
• Verify quantity restrictions
• Consider alternate routes if tunnels restrict passage
• Keep proper documentation if required

By following these guidelines, you can safely transport dry ice while maintaining its cooling effectiveness and ensuring passenger safety.
