First of all: be careful! Dry ice is extremely cold and can hurt if it touches your bare skin. If the ice has spilled out of its bag, please use gloves, a towel, or a pot-holder to move it aside as you unpack your box. If the ice is still in its bag, you can put the bag in your sink to finish sublimating, or place it outside. You, your family, and your pets are not at risk of any fumes, so long as there is some basic airflow in your space (the amount of ice required for toxicity is way more than what we pack!). The amount of ice remaining in your shipment upon delivery will not damage your pipes while it sublimates.
