Can you eat dry ice?

In this brief guide, we’ll address the query: “Can you eat dry ice?” Also, we’ll explore what happens if you eat dry ice, what dry ice is made out of, what are the uses of dry ice, and how to dispose of dry ice. 

Can you eat dry ice? 

No, you should not ingest dry ice under any circumstance. Unlike ice made out of water, dry ice is made out of pressurized and solidified carbon dioxide, which has a much lower freezing point (-78°C) than water (0°C). 

It’s by no means toxic, but its temperature makes it more hazardous to handle than regular ice, which even with its higher solidifying temperature, can still cause damage. 

What happens if I eat dry ice? 

If you eat dry ice, you’ll most likely suffer lesions in the skin, tissues, and membranes that come into contact with chunks. 

While it remains solid, dry ice has a much lower temperature than conventional ice, and it will inflict burns to cells to the cells that it touches 

What is dry ice made out of? 

Dry ice is made of pressurized carbon dioxide that has been stored in containers and formed into solid chunks, pellets, or blocks. 

Contrary to what one would assume occurs, carbon dioxide made into dry ice does not pass through a liquid phase when it melts but rather; it sublimates, which is the name for the physical change matter undergoes when it transitions from a solid state to gas. 

Therefore, it receives the moniker -dry ice- as it will leave no traces of liquid the way melted conventional ice does. 

What are the uses of dry ice? 

Dry ice has many uses. It can be used in the shipping industry to transport vacuum-sealed perishable goods. This may include foods, medications, and other special products such as enzymes and lab reagents.

Other specialized industrial uses may include being used to generate effects for the entertainment industry and using it to store sensitive reagents and items. 

Additionally,  dry ice can be used to flash-freeze freshly processed foods such as meats, seafood, vegetables, and other types. 

It can also be used to preserve items that are sensitive to humidity when defrosted. 

There are a plethora of applications for dry ice, though, to be clear, it should be handled by those who have completed safety training and are aware of the dangers it can pose to one’s health. 

How should I handle dry ice? 

Dry ice should ideally be handled by professionals who have completed certified training courses. 

However, we’ll list a few guidelines you should follow if you find yourself faced with handling a product packaged with dry ice. 

  • Avoid touching it with bare hands, and if possible, use insulating equipment.
  • Under no circumstance should you ingest it. Dry ice will inflict burns on your mouth, esophagus, and digestive tract. Additionally, you will suffer bloating, as the melting block of dry ice will release gas, which will inevitably expand.
  • Don’t leave it within the reach of small children, as they may suffer lesions from experimenting with it.
  • Avoid leaving it in unventilated places where the gas can build up. High concentrations of carbon dioxide can noxious effects on a person’s health, and carbon dioxide should be stored in a well-ventilated place where this will not occur.

This means that you cannot place dry ice in a walk-in freezer, a refrigerator freezer, or a chest freezer, as the ice will melt and gas will build up. It also cannot be stored in a small, tight-sealing locking cooler, as it may explode. 

How should I dispose of dry ice? 

Dry ice should be disposed of by leaving it to return to its gas state in an open area. This may be done outdoors, or in a room that is well-ventilated. 

Under no circumstances should you try to bottle dry ice, place it in a domestic freezer for future use, or leave it in a poorly ventilated space such as a closet, a maintenance room, or an elevator. 

Pouring it down the drain is also out of the question, as the expanding gas can burst pipes and cause plumbing troubles. 

A build-up of carbon dioxide can be potentially lethal to a person’s health, and symptoms of intoxication may require emergency medical intervention. 

We advise our readers to always be familiar with the usage guidelines for any industrial reagent or material they intend on handling and have emergency measures in place in case of accidents
