Frequently Asked Questions
Why does dry ice sublimate?
The reason dry ice sublimates is that it transitions directly from a solid to a gas at temperatures above -78.5°C (-109.3°F), without becoming a liquid, due to its unique properties as a solid form of carbon dioxide.
What is dry ice blasting?
Dry ice blasting is a cleaning method that utilizes compressed air to propel dry ice pellets onto surfaces, effectively removing contaminants and coatings without damaging the underlying material. This environmentally safe technique is ideal for industrial and commercial applications.
How does dry ice blasting work?
Dry ice blasting works by propelling solid carbon dioxide pellets at high speeds to impact and clean surfaces. Upon contact, the dry ice sublimates, effectively lifting contaminants without damaging the underlying material, making it an efficient cleaning method for industrial surfaces.
Can dry ice blasting remove rust?
Dry ice blasting can effectively remove rust from various surfaces. This cleaning method utilizes compressed CO2 pellets to gently blast away rust without damaging the underlying material, making it an efficient choice for surface preparation.
Is dry ice blasting good for certain applications?
Dry ice blasting is effective for various applications, including industrial cleaning, coating removal, and surface preparation. Its non-abrasive nature makes it suitable for delicate surfaces, ensuring thorough cleaning without damage.
How much does dry ice cost in Canada?
The cost of dry ice in Canada typically ranges from $1.50 to $3.00 per kilogram, depending on the supplier and location. Prices may vary, so it's advisable to check with local distributors for the most accurate rates.
Where to buy dry ice in Ontario?

Where to get dry ice in Toronto?
To obtain dry ice in Toronto, you can visit suppliers such as air gas companies, local dry ice distributors, or some grocery stores that offer specialty items. Always call ahead to confirm availability.
Can dry ice cause frostbite?
Dry ice can cause frostbite. When in direct contact with skin, its extremely low temperature can lead to tissue damage, resulting in frostbite if proper precautions are not taken. Always handle dry ice with protective gloves.
How is dry ice made?
Dry ice is made by pressurizing and cooling carbon dioxide gas into a liquid form, which is then expanded rapidly. This process causes the liquid to freeze into solid carbon dioxide, creating dry ice in pellet or block form.
Can dry ice touch food?
Dry ice can touch food, but it should only be used in limited quantities and for short durations. Excessive contact may cause freezing or damage to the food. Always handle dry ice with caution to ensure safety.
Is dry ice legal in Canada?
Dry ice is legal in Canada. It is commonly used for various applications, including industrial cleaning and cooling, and can be purchased and distributed without restriction, provided safety regulations are followed.
Can dry ice be shipped within Canada?
Dry ice can be shipped within Canada, but specific regulations and guidelines must be followed. It’s important to consult with shipping providers for proper packaging and handling requirements to ensure safe transport.
Where to buy dry ice in Whitby, Ontario?
The best places to buy dry ice in Whitby, Ontario, include local grocery stores, ice suppliers, or specialty gas companies. It's recommended to call ahead to ensure availability and confirm purchasing options.
What industries use dry ice blasting?

What precautions are needed for dry ice blasting?
Precautions needed for dry ice blasting include ensuring proper ventilation, using protective gear like gloves and goggles, and training operators on safety protocols to mitigate risks associated with carbon dioxide exposure and to maintain a safe working environment.
How environmentally friendly is dry ice blasting?
The environmental friendliness of dry ice blasting is significant. This method uses non-toxic, biodegradable dry ice pellets that sublimate, leaving no harmful residues, and it reduces water usage compared to traditional cleaning techniques, making it a sustainable choice for surface preparation.
What are the benefits of dry ice blasting?
The benefits of dry ice blasting include its environmentally friendly nature, effectiveness in removing contaminants without damaging surfaces, and efficiency in preparing for painting. This method ensures a cleaner and safer environment for industrial and commercial applications.
How does dry ice compare to traditional ice?
Dry ice differs from traditional ice primarily in that it sublimates directly into carbon dioxide gas without leaving any residue, making it ideal for cleaning and surface preparation processes, while traditional ice melts into water.
What safety gear is required for handling dry ice?
The safety gear required for handling dry ice includes insulated gloves to prevent skin burns, safety goggles to protect your eyes from any flying particles, and a lab coat or protective clothing to safeguard against potential splashes or contact.
How long does dry ice last during shipping?
The longevity of dry ice during shipping depends on several factors, including the size of the dry ice blocks and the packaging. Generally, dry ice lasts between 18 to 24 hours if properly insulated.
What are common uses for dry ice in Toronto?
Common uses for dry ice in Toronto include industrial cleaning, food preservation and transportation, special effects in entertainment, and scientific applications in laboratories. Its versatility makes it a popular choice for various commercial and industrial needs.
How do temperatures affect dry ice sublimation rates?
The effect of temperatures on dry ice sublimation rates is significant. As temperatures rise, dry ice sublimates more quickly, transitioning from solid to gas at a faster rate, which can impact its effectiveness in surface preparation processes.
What certifications are needed for dry ice blasting services?
The certifications needed for dry ice blasting services typically include OSHA (Occupational Safety and Health Administration) training, specialized training for operating dry ice blasting equipment, and any relevant provincial or federal environmental compliance certifications.
How does dry ice blasting impact surface materials?
The impact of dry ice blasting on surface materials is minimal, as the method effectively removes contaminants without causing damage. It preserves the integrity of various surfaces, making it ideal for preparing them for further treatment or painting.
Can dry ice blasting clean electrical equipment?
Dry ice blasting can effectively clean electrical equipment. This method uses CO2 pellets that evaporate upon impact, ensuring no moisture is left behind, making it safe and efficient for sensitive electrical components.
What are the storage requirements for dry ice?
The storage requirements for dry ice are that it should be kept in a well-ventilated area in an insulated container, away from direct sunlight and moisture, to prevent sublimation and ensure safety.
How do you dispose of unused dry ice?
The disposal of unused dry ice involves allowing it to sublimate in a well-ventilated area. Ensure that it is placed in an open space where it can safely become carbon dioxide gas without risk to yourself or others.
Can dry ice blasting be used on wood?
Dry ice blasting can be effectively used on wood surfaces. This method safely cleans and removes old coatings without damaging the wood, making it an ideal option for preparation prior to finishing or painting projects.
What are the risks of dry ice blasting indoors?
