Though brief contact is harmless, prolonged contact with skin can freeze the cells and burn you in a manner similar to fire.  An oven mitt or towel can also work, but it will not offer the same protection as gloves.  Treat dry ice like you would a hot frying pan by keeping your skin out of contact. Treat dry ice burns as you would typical burns.  If your skin is only red, it will heal in time.  If your skin blisters or comes off, treat the area with antibiotic ointment and wrap with a bandage.  Consult a doctor immediately in cases of extreme burns. Storing large quantities of dry ice in airtight areas can create an oxygen deficient atmosphere.  A locked storage shed in your backyard will have good air circulation and won't be in danger of suffocating people or animals.  If you're having trouble finding a good place to keep dry ice, ask a chemistry teacher at your school if there is a safe place to store dry ice in the chemistry lab. Make sure you store dry ice away from young children and pets. The dry ice will continue sublimating but will need to be able to mix with the air more easily. Dry ice is heavier than oxygen and will accumulate in low areas of the spill area.  Avoid putting your face near pits or other low, confined areas as these places will have the highest concentration of carbon dioxide. If you find yourself with extra dry ice, remember that it is constantly undergoing sublimation and simply needs to be left alone in order to evaporate.  Your backyard porch is a good place to dispose of dry ice.  Make sure it is safely out of reach of others for at least 24 hours. You can also use a fume hood to dispose of dry ice.  A fume hood is a ventilated enclosure where harmful chemicals can be used or kept.  Your school chemistry lab may have a fume hood where you can leave the excess dry ice.  Be sure you ask a teacher first before doing so.
