You may be familiar with dry ice because you use it around Halloween or during the summer to keep drinks cold. Dry ice has multiple uses and is particularly useful if the freezer breaks. Carbon dioxide in solid form is known as dry ice. When it dissolves, it reverts to the gaseous state in the form of carbon dioxide, which is colorless and tasteless. Dry ice can be used effectively as long as you follow the safety rules for handling and storing it.
Steps
Step 1. Get dry ice when you need it
This is because it transforms from solid to gaseous state at a rate of 10%, or loses 2 to 4.5 kg, every 24 hours. Therefore, it is best that it does not disappear before you can use it.
Step 2. Handle it carefully
Use a pair of insulated oven mitts or towels to handle the dry ice, otherwise you will burn your hands. It can reach a temperature of -79 ° C. Burns caused by dry ice have effects similar to those of freezing.
Step 3. Transport the dry ice in a well-ventilated vehicle
Dry ice is basically carbon dioxide, and carbon dioxide is bad for health when found in large or concentrated quantities. If too much dry ice gas accumulates in a small space, there is a risk of carbon dioxide poisoning. Therefore, drive with the windows open when transporting dry ice.
Step 4. Store dry ice in a well-ventilated place
It should not be stored in a small space where the gas is likely to accumulate and become dangerous. Keep it in a place where there is air circulation. Do not store it in a cooler bag, closed vehicle or cooler. Carbon dioxide, both in gaseous and solid form, is heavier than air and is deposited in low-lying areas.
Step 5. Use or place dry ice in a well-ventilated area and on a surface that tolerates intense cold
Kitchen countertops are not ideal, as they could crack. If you want to use dry ice to remedy a broken freezer or refrigerator, the amount needed is so small that it shouldn't cause any ill effects.
Step 6. Dispose of dry ice by turning it into a gaseous state
Leave it at room temperature and don't throw it in the trash, toilet, sink, or tub.
Advice
- Proper ventilation is required to use dry ice.
- Treat dry ice burns such as those caused by heat sources.
- If you need to cut or cut a small piece of dry ice, wear goggles and face protection.
Warnings
- Symptoms of carbon dioxide poisoning include headache, nausea, difficulty breathing, and vomiting.
- Always keep dry ice out of the reach of children.
- Don't breathe the dry ice.
- Do not eat or ingest dry ice.
