Dry Ice in Seattle, WA: Your Complete Guide

Dry ice, the solid form of carbon dioxide, is readily available in Seattle, WA, serving various purposes from scientific experiments to keeping food cold during transport. You can easily find it at grocery stores, welding supply stores, and dedicated dry ice suppliers throughout the city. This guide will help you locate and utilize dry ice safely in Seattle.

What is Dry Ice and its Uses?

Dry ice is solidified carbon dioxide (CO2) at a temperature of -109.3°F (-78.5°C). It sublimes, meaning it transitions directly from a solid to a gas without passing through a liquid phase. This makes it an effective refrigerant, as it doesn’t leave behind any water residue. Common uses include:

• Food Preservation: Keeping frozen foods cold during transport or power outages.
• Scientific Experiments: Creating fog effects, flash freezing samples, and other lab applications.
• Special Effects: Generating spooky fog for Halloween or theatrical productions.
• Cleaning: Dry ice blasting is used for industrial cleaning, removing paint, mold, and other contaminants.
• Shipping: Keeping temperature-sensitive materials like pharmaceuticals and biological samples cold during transit.

Where to Buy Dry Ice in Seattle

Several options are available for purchasing dry ice in Seattle:

• Grocery Stores: Some larger grocery chains like Fred Meyer and QFC may carry dry ice. Call ahead to confirm availability.
• Welding Supply Stores: Airgas and other welding supply stores often sell dry ice for industrial purposes.
• Dedicated Dry Ice Suppliers: These suppliers offer a wider range of quantities and may provide specialized services.
• Party Supply Stores: Some party supply stores might carry dry ice, especially around Halloween.

It is essential to call ahead to ensure the location has dry ice in stock, as availability can fluctuate. Always inquire about the price and available quantities.

Dry Ice Safety Precautions

Dry ice can cause severe burns due to its extremely low temperature. Always handle it with insulated gloves or tongs. Never touch it with bare skin. Additionally, because dry ice sublimates into carbon dioxide gas, it’s important to use it in a well-ventilated area to prevent carbon dioxide buildup. Avoid storing dry ice in airtight containers, as the pressure from the sublimating gas can cause them to explode. For more detailed information on the chemical properties and hazards of carbon dioxide, consult Carbon Dioxide on Wikipedia.

Cost of Dry Ice in Seattle

The price of dry ice varies depending on the supplier and the quantity purchased. Generally, you can expect to pay between $1 and $3 per pound. Buying in bulk often results in a lower per-pound price. Check with individual suppliers for current pricing.

Frequently Asked Questions

Is dry ice dangerous to transport in my car?

Yes, but with precautions. Transport dry ice in a well-ventilated vehicle. Keep windows slightly open to allow carbon dioxide gas to escape. Do not transport dry ice in the passenger compartment if possible; a trunk or truck bed is preferable.

How long does dry ice last?

The sublimation rate of dry ice depends on several factors, including the size of the block, the insulation, and the ambient temperature. Generally, dry ice sublimates at a rate of about 5 to 10 pounds every 24 hours in a typical insulated container.

Can I put dry ice in my freezer to make it colder?

No, it is not recommended. Dry ice is much colder than a freezer and can damage the freezer’s components. Additionally, the carbon dioxide gas can displace oxygen and potentially create a hazard.

What do I do with leftover dry ice?

Allow the dry ice to sublimate in a well-ventilated area. Never dispose of dry ice in a sink, toilet, or trash can. Avoid placing it in areas where children or pets may come into contact with it.

Can I use dry ice to make homemade ice cream?

Yes, dry ice can be used to quickly freeze ice cream. However, it requires careful handling and precise measurements. Consult a recipe specifically designed for dry ice ice cream to ensure safety and proper texture.

Summary

Dry ice is a useful and versatile product readily available in Seattle. Knowing where to purchase it and how to handle it safely is crucial. Always remember to wear gloves, ensure adequate ventilation, and dispose of it properly.
