Before you drive
Put the cooler in the trunk or cargo area where practical, secure it so it can't tip, and don't leave it in a parked vehicle.
While driving
Keep fresh air flowing. If anyone feels headache, dizziness or shortness of breath, pull over safely, open windows and get fresh air.
Ventilation
Dry ice turns into carbon dioxide gas. Always use it in a well-ventilated area and never in a sealed room, walk-in space or closed vehicle cabin.
Dry ice releases carbon dioxide gas and requires proper ventilation. Handle only with insulated gloves, and never seal it in an airtight container.
