How much dry ice is toxic?
OSHA limits CO2 8 hr. exposure to 5000 ppm or 0.5%. Levels approaching 4% are dangerous. This means that as little as 5 pounds of dry ice left over the weekend in a walk-in cooler with no air circulation could potentially raise the CO2 to a hazardous level by the start of work on a Monday morning!
Is dry ice toxic?
If dry ice is stored in an area without proper ventilation, it may cause people to inhale large amounts of the gas CO2, which displaces oxygen in the body, the CDC says. This, in turn, can lead to harmful effects, including headache, confusion, disorientation and death.
Can you touch dry ice with gloves?

What are the dangers associated with handling dry ice with your bare hands what precautions should you take when handling dry ice in this experiment?
Protect your hands and eyes. The extremely cold surface temperature of dry ice means that it can cause skin damage and frostbite. Follow these steps to help prevent contact injuries: Don't touch dry ice with your bare hands. Nitrile exam gloves will not give you enough protection.
Can dry ice poison you?
It is very dangerous to use dry ice in a walk-in freezer, cooler, closed truck bed, or other small space with poor ventilation. A large amount of dry ice in a walk-in cooler or freezer can produce a great deal of carbon dioxide, which can possibly be fatal to someone entering that space.
Is dry ice harmful to skin?
The Effect of Dry Ice If you touch dry ice momentarily without protective gear, it can cause redness to the affected skin. If you hold dry ice in your hand for a longer time, you can get frostbite.

The use of dry ice can lead to cases of poisoning from carbon dioxide (CO2), since dry ice sublimes to gaseous CO2. Known fatalities caused by CO2 typically result from an acute toxic effect by inhalation in enclosed spaces.
