Risks of Using Dry Ice:

• Frostbite: Direct contact can cause severe frostbite due to its extremely low temperature. Always wear gloves and handle it with care.
• Asphyxiation: As it sublimates, dry ice releases carbon dioxide gas, which can displace oxygen in a confined space and lead to asphyxiation. Use it in well-ventilated areas.
• Explosion: If sealed in an airtight container, the pressure from the sublimating gas can cause an explosion.

How Much Does Dry Ice Cost?

The cost of dry ice can vary depending on several factors:

• Quantity: Generally, the more you buy, the lower the price per pound. Small quantities may cost more per pound than bulk purchases.
• Vendor: Different suppliers have different pricing structures. Major retailers might offer competitive prices, while specialty gas suppliers could be more expensive.
• Location: Prices can fluctuate based on geographic location due to shipping costs and local demand. Areas with higher demand or limited suppliers may have higher prices.
• Form: Dry ice is available in various forms, including blocks and pellets. Pellets are often slightly more expensive due to the additional processing involved.

Typical Price Range:

On average, you can expect to pay between $1 and $3 per pound for dry ice. However, this is just an estimate. Here’s a more detailed breakdown:

• Small Quantities (5-10 lbs): $2 to $3 per pound
• Medium Quantities (10-25 lbs): $1.50 to $2.50 per pound
• Large Quantities (Over 25 lbs): $1 to $2 per pound

Where to Buy Dry Ice:

• Major Retailers: Many large retailers like Walmart and Kroger sell dry ice, often at competitive prices. Check their websites or call your local store to confirm availability.
