Safety and Handling advice

How much should I order to take into account natural sublimation?

Nippon Gasses recommends ordering the quantity of dry ice required for your immediate or short-term use. As a guide, Dry Ice typically sublimates at a rate of 5% to 15% product weight per day depending on the thermal properties of the storage container and the external temperature profile. Product shelf life is variable and significantly affected by other factors such as the quantity of residue product in the insulated storage container and number of times the container lid is opened.

Can I transport it myself?

The sublimation of dry ice inside a vehicle may lead to the accumulation of dangerous concentrations of carbon dioxide, which can lead to suffocation. Dry Ice can be transported without any special ventilation measures when the dry ice is totally segregated away from the driver cab, within the external load compartment of the delivery vehicle. When transporting Dry Ice, before entering the external load compartment, always allow time for the compartment to thoroughly ventilate before entering.

How should I use it?

• DO NOT USE DRY ICE IN CONFINED SPACES

  Dry ice generates CO2 gas by sublimation, which can cause rapid suffocation due to depletion of oxygen.

• AVOID CONTACT WITH SKIN AND EYES

  The low temperature of dry ice (-78.6ºC) can cause severe burns upon direct contact with the skin and eyes.

• NEVER HANDLE DRY ICE WITH NAKED HANDS

  The use of suitable protective gloves is mandatory. It is advisable to use safety glasses, long-sleeved shirts and long-legged trousers fully covering the limbs, and protective footwear.

• NEVER PUT DRY ICE IN YOUR MOUTH

  If ingested accidentally, dry ice can cause severe injuries by burning. Never put dry ice in beverages to cool them.

• KEEP AWAY FROM CHILDREN’S REACH

  Dry ice should only be handled by adults.

If there is any Drikold™ left over, how do I store it?

One kilogram of dry ice sublimates into around 0.5 cubic meters of carbon dioxide gas, something that should be taken into account in order to avoid storing it in airtight containers or in chambers where a person can enter.

• NEVER STORE DRY ICE IN GLASS OR AIRTIGHT CONTAINERS

  Storage in airtight or sealed containers could cause them to break due to excess pressure build up.

• NEVER STORE DRY ICE IN DOMESTIC REFRIGERATORS OR FREEZING CHAMBERS, NOR IN CONFINED AREAS.

  Storage in chambers designed for keeping refrigerated or frozen products, or in any confined area with inadequate ventilation can lead to accumulation of dangerous concentrations of carbon dioxide leading to asphyxiation.

• NEVER STORE DRY ICE IN AIRTIGHT CONTAINERS OR BEVERAGE BOTTLES

  They can burst when the CO2 pressure builds up as the dry ice sublimes.
