Handling  

  1. Always handle Dry Ice with protective thermal gloves
  2. Use a hammer to break up the larger pieces if smaller pieces are desired.

Hazards/Precautions:

  1. Burns/frostbite:  Dry ice can cause burns to the skin in short periods of times.  Thermal rated gloves are to be used to handle dry ice.
  2. Suffocation:  carbon dioxide is a simple asphyxiant.  Always store dry ice in a well-ventilated area to minimize the buildup of carbon dioxide.  Personnel must use caution should dry ice be stored in a deep cooler.  Never stick their head into the chest to obtain dry ice.
  3. Explosions:  Placing dry ice into a tightly sealed container can permit sufficient gas build up to cause an explosion. Never place dry ice inside an ultra-low freezer or other enclosed space! Do not store dry ice in a confined area such as in walk-in coolers, refrigerators or freezers.
  4. When using dry ice to ship materials, the shipper must follow all applicable shipping regulations.

Disposal of unneeded dry ice:

  1. Let the unused portion sublimate (recommended for well-ventilated locations because it will occur over a period of several days and the ventilation will take care of the gas liberated).
  2. NEVER dispose of dry ice in a sink or other drain (such action can destroy the structure because of the temperature difference).
  3. NEVER dispose of dry ice in the trash or garbage.
  4. NEVER place unneeded dry ice in corridors (some corridors may not be well ventilated and the oxygen level can be reduced to low levels).
