Dry ice is hazardous if handled without gloves and kids should not be  
the ones handling it. Read below.

Safe Handling
 	AVOID CONTACT WITH SKIN AND EYES! Dry ice is extremely cold, -109 
F (-79C) and can cause severe frostbite within seconds of direct  
contact. (Frostbite is a freezing injury resembling a burn.)
 	NEVER HANDLE DRY ICE WITH YOUR BARE HANDS. Always wear insulated  
gloves. Safety glasses, long-sleeved shirt, long pants and shoes are  
also recommended. Use tongs to handle blocks of dry ice.
 	DO NOT PUT DRY ICE IN YOUR MOUTH OR OTHERWISE INGEST IT. If dry  
ice is accidentally ingested, it can cause severe internal injury.  
Never put dry ice in beverages to cool them.
 	KEEP OUT OF REACH OF CHILDREN. Only adults should handle dry ice.
 	OBTAIN DRY ICE IN THE FORM AND SIZE IN WHICH IT WILL BE USED.  
Never saw a block of dry ice; never use a hammer to break a block of  
dry ice into smaller pieces.
 	TRANSPORT DRY ICE IN YOUR VEHICLE TRUNK OR TRUCK BED. Leave  
windows open for fresh air circulation. Never leave dry ice in a  
parked passenger vehicle. Sublimation of dry ice in a closed  
passenger vehicle can result in the accumulation of dangerous  
concentrations of asphyxiating carbon dioxide vapor. Dry ice can be  
safely transported without special ventilation in the closed cargo  
area of a truck if all occupants are restricted to the cab. When  
opening a closed cargo area containing dry ice, allow the closed  
space to ventilate for 5 minutes before entering.
 	NEVER STORE DRY ICE IN GLASS OR OTHER SEALED (AIRTIGHT) CONTAINERS  
OR COOLERS. Storage in a sealed container can result in a rupture or  
explosion of the container from over-pressurization.
 	DO NOT USE DRY ICE IN CONFINED AREAS. Dry ice releases heavy  
carbon dioxide vapor that can cause rapid suffocation.
 	DO NOT PLACE DRY ICE ON A TILE OR LAMINATED COUNTER TOP. Instead,  
use a solid surface - a wood cutting board or piece of plywood is  
best. Dry ice is sometimes used in tile removal and may destroy the  
bonding agent holding the tile or laminated material in place.
 	DO NOT PLACE DRY ICE IN DIRECT CONTACT WITH PERISHABLE FOODS OR  
BOTTLED/CANNED BEVERAGES. Produce may sustain severe freezer burns  
and bottle/canned beverages may split or explode.
