SAFE HANDLING OF DRY ICE

Caution: Keep Dry Ice away from children if they cannot be closely supervised at all times.


HANDLING
Dry Ice temperature is extremely cold at -109.3°F or -78.5°C. Always handle Dry Ice with care and wear protective cloth or leather gloves whenever touching it. An oven mitt or towel will work. If touched briefly it is harmless, but prolonged contact with the skin will freeze cells and cause injury similar to a burn.


BURN TREATMENT
Treat Dry Ice burns the same as a regular heat burns. See a doctor if the skin blisters or comes off. Otherwise if only red it will heal in time as any other burn. Apply antibiotic ointment to prevent infection and bandage only if the burned skin area needs to be protected.


STORAGE
Store Dry Ice in an insulated container. The thicker the insulation, the slower it will sublimate. Do not store Dry Ice in a completely airtight container. The sublimation of Dry Ice to Carbon Dioxide gas will cause any airtight container to expand or possibly explode. Keep proper air ventilation wherever Dry Ice is stored. Do not store Dry Ice in unventilated rooms, cellars, autos or boat holds. The sublimated Carbon Dioxide gas will sink to low areas and replace oxygenated air. This could cause suffocation if breathed exclusively. Do not store Dry Ice in a refrigerator freezer. The extremely cold temperature will cause your thermostat to turn off the freezer. It will keep everything frozen in the freezer but it will be used up at a faster rate. It is the perfect thing if your refrigerator breaks down in an emergency.


VENTILATION
Normal air is 78% Nitrogen, 21% Oxygen and only 0.035% Carbon Dioxide. If the concentration of carbon dioxide in the air rises above 5%, carbon dioxide can become toxic. Smaller concentrations can cause quicker breathing but is otherwise not harmful. If Dry Ice has been in a closed auto, van, room, or walk-in, for more than 15 minutes, open doors and allow adequate ventilation before entering. Leave area containing Dry Ice if you start to pant and breath quickly. This is the sign that you have breathed in too much CO2 and not enough oxygen. Dry Ice CO2 is heavier than air and will accumulate in low spaces. Do not enter closed storage areas that have or have had Dry Ice before airing out completely.


PICK-UP TIME AND TRANSPORTING
Plan to pick up the Dry Ice as close to the time it is needed as possible.
It sublimates at 10%, or 5 to 10 pounds every 24 hours, whichever is greater.
Carry it in a well-insulated container such as an ice chest.
If it is transported inside a car or van for more than 15 minutes make sure there is fresh air. After 15 minutes with Dry Ice only in its paper bag in the passenger seat next to me, I started to breathe faster and faster as though I were running a race. I couldn't figure out why I was so out of breath until I saw the car air system was set in the re-circulated position, not fresh outside air.


DISPOSAL
Unwrap and leave it at room temperature in a well-ventilated area. It will sublimate from a solid to a gas.


TILE COUNTERTOPS
Do not leave Dry Ice on a tiled countertop as the extreme cold could crack it.


DO NOT leave Dry Ice unattended around children.

2. COMPOSITION/INFORMATION ON INGREDIENTS

Substance / Preparation: Substance
Components / Impurities: Contains no other components or impurities, which will influence the classification of the product.
CAS Nr: 00124-38-9
EEC Nr (from EINECS): 2046969


3. HAZARDS IDENTIFICATION

Hazards Identification: Solid. Contact with product may cause cold burns or frostbite. In high concentrations sublimed vapour may cause asphyxiation.


4. FIRST AID MEASURES

Inhalation of Sublimed Vapour: In high concentrations may cause asphyxiation. Symptoms may include loss of mobility/consciousness. Victim may not be aware of asphyxiation. Low concentrations of CO2 caused increased respiration and headache. Remove victim to uncontaminated area wearing self contained breathing apparatus. Keep victim warm and rested. Call a doctor. Apply artificial respiration if breathing stopped.


Skin / eye contact with Dry Ice: Immediately flush eyes thoroughly with water for at least 15 minutes. In case of frostbite spray with tempid water for at least 15 minutes. Apply a sterile dressing. Obtain medical assistance.


5. FIRE FIGHTING MEASURES

Specific Hazards: Non flammable
Hazardous combustion products: None
Suitable Extinguishing Media: All known extinguishants can be used
Specific Methods: Water on Dry Ice (Solid Carbon Dioxide) increases sublimation. Higher risk of asphyxiation.
Special Protective Equipment for Fire Fighters: In confined space use self-contained breathing apparatus.

6. ACCIDENTAL RELEASE MEASURES

Personal Precautions: Evacuate area. Use protective clothing. Wear self-contained breathing apparatus when entering are unless atmosphere is proved safe. Ensure adequate air ventilation.
Environmental Precautions: Try to stop release. Prevent from entering sewers, basements and workpits, or any place where its accumulation can be dangerous.
Clean Up Methods: Ventilate area.

7. HANDLING AND STORAGE

Handling and Storage: Use only properly specified equipment which is suitable for this product. Contact your supplier if in doubt. Refer to supplier’s container handling instructions. Keep container in a well ventilated place.
