Health and Safety Guidelines for Dry Ice Handling in Pakistan


In Pakistan’s rapidly advancing industries and laboratories, the utilization of dry ice has become increasingly prevalent. Dry ice, essentially solidified carbon dioxide (CO2) at an incredibly low temperature, is a versatile substance with a broad spectrum of applications. These range from preserving perishable items to creating special effects in the entertainment industry. However, the handling of dry ice demands extreme caution and adherence to safety guidelines to prevent potential hazards. In this comprehensive guide, we will delve into essential health and safety guidelines for the proper handling of dry ice in Pakistan.

Understanding Dry Ice

What is Dry Ice?

Dry ice is the solid form of carbon dioxide (CO2) that exists at an extraordinarily low temperature of -78.5°C (-109.3°F). It earns its name from the fact that it undergoes sublimation, transitioning directly from a solid to a gas without leaving any liquid residue. This unique property makes dry ice ideal for various applications where traditional ice falls short.

Properties of Dry Ice

Dry ice’s extreme cold temperature not only makes it an effective cooling agent but also poses risks due to this very property. Understanding its properties, such as sublimation and the release of CO2 gas, is vital for safe handling.

Hazards of Dry Ice Handling

Temperature Concerns

The extreme coldness of dry ice can lead to frostbite and cold burns upon contact with the skin. It is imperative to understand how to mitigate these risks effectively.

Ventilation Issues

Dry ice undergoes sublimation, turning into CO2 gas, which can displace oxygen in confined spaces, potentially causing asphyxiation. Adequate ventilation is crucial to prevent this hazard.

Skin and Eye Contact Risks

Direct contact with dry ice can result in severe injuries to the skin and eyes. Proper protection is paramount to avoid these dangers.

Safety Equipment and Gear

Personal Protective Equipment (PPE)

Wearing the appropriate PPE, including insulated gloves, safety goggles, and lab coats, is non-negotiable when handling dry ice.

Handling Tools

The use of suitable tools such as insulated containers and tongs ensures safe and controlled handling.

Ventilation Systems

Effective ventilation systems in laboratories and storage areas are vital to prevent the buildup of CO2 gas, maintaining a safe environment.

Proper Storage of Dry Ice

Temperature Requirements

Storing dry ice at the correct temperature is essential to maintain its integrity and safety.

Insulated Containers

Insulated containers help regulate temperature and prevent excessive sublimation.


Even during storage, proper ventilation ensures the release of CO2 gas, maintaining a safe environment.

Transportation Guidelines

Securing Dry Ice during Transit

Properly securing dry ice during transportation prevents accidents and exposure to extreme cold.
