Safe Handling Practices for Dry Ice
Dry ice (solid carbon dioxide) is an extremely cold material (-109.3°F or -78.5°C) and poses unique hazards if not handled properly. For your safety and to ensure effective use, please follow these guidelines:
1. Always Wear Protective Equipment
Use Insulated Gloves: Always wear thick, insulated gloves when handling dry ice to prevent frostbite or cold burns. Avoid direct contact with skin.
Use Eye Protection: When handling dry ice in any capacity, wear safety goggles to protect against flying particles.
2. Ensure Proper Ventilation
Prevent Carbon Dioxide Buildup: Dry ice sublimates into carbon dioxide gas, which can displace oxygen in enclosed spaces. Use in well-ventilated areas to avoid asphyxiation risks.
Avoid Confined Spaces: Never store or use dry ice in small, enclosed areas such as walk-in coolers, vehicles, or confined rooms without adequate airflow.
3. Safe Transport and Storage
Use Insulated Containers: Transport dry ice in insulated coolers, but do not seal the lid tightly. Dry ice releases gas as it sublimates, and pressure buildup in airtight containers can cause them to burst.
Do Not Store in Freezers or Refrigerators: Dry ice is much colder than regular freezers and can damage them. Use designated insulated containers for storage.
4. Handling and Usage Precautions
Do Not Eat or Ingest: Dry ice is not edible. Ingesting even a small amount can cause severe internal injury due to extreme cold.
Keep Away from Children and Pets: Dry ice can cause serious injury if touched or ingested. Store it out of reach.
5. Disposal Guidelines
Allow to Sublimate in Open Air: Let unused dry ice sublimate (turn to gas) in a well-ventilated area, away from children, pets, and any confined spaces.
Never Dispose in Drains, Toilets, or Trash Compactors: The extreme cold can damage plumbing and equipment, and the gas released can create pressure hazards.
6. Emergency Procedures
Frostbite Treatment: If dry ice comes into contact with your skin, it can cause frostbite. Immediately rinse the area with lukewarm (not hot) water and seek medical attention if necessary.
Exposure to High Concentrations of Carbon Dioxide: Symptoms of CO₂ exposure include dizziness, shortness of breath, and confusion. If someone is exposed, move them to fresh air immediately and call emergency services if symptoms persist.
By following these safe handling practices, you can safely and effectively use dry ice for your applications. Additional safety information can be found in our dry ice Safety Data Sheet here.
