Does Dry Ice Need to Be Ventilated?

Dry ice changes to a gas very rapidly at room temperature, displacing oxygen. Only use dry ice in open or well-ventilated areas. Airtight containers may explode as dry ice rapidly expands to a gas when exposed to temperatures above -109°F (-78°C). Dry ice is the frozen form of carbon dioxide.

Do you need ventilation with dry ice?

Dry ice will always have some amount of sublimation, so dry ice must be ventilated at all times to let out the gas. However, keeping dry ice in a thickly insulated cooler will keep it from sublimating as quickly. Dry ice sublimates faster when exposed to air.

Can you put dry ice directly in a cooler?

Put the dry ice on the bottom of the cooler or on top of cooler contents. Use the newspaper to fill empty space within the cooler. Dry ice can be used in conjunction with conventional ice. Keep dry ice from coming in contact with water to extend dry ice life.
