Final answer:
Individuals purchasing Dry Ice should typically be at least 18 years old, with regulations varying by jurisdiction. Handling dry ice requires taking safety precautions due to its extremely cold temperature and sublimation properties.
Step-by-step explanation:
In regards to purchasing Dry Ice, regulations for sale may vary by jurisdiction, but typically, an individual should be of legal adult age, which often means being at least 18 years old. Dry ice, a form of solid carbon dioxide, has various uses including the cooling of items during shipment. Due to the potential risks associated with handling it, such as burns due to its extremely cold temperature (-78°C) or risks from gas build-up where ventilation is poor, certain safety precautions are necessary when purchasing and handling dry ice.
Those handling dry ice should have the appropriate knowledge and skills to do so safely, which is why retailers may impose an age restriction. While specific age requirements can differ by country and vendor, it is essential to check local regulations and vendor policies. Construction workers, salespeople, and white-collar workers must adhere to the same safety standards and regulations, emphasizing the fact that appropriate precautions must be taken by anyone who uses or comes into contact with dry ice, regardless of the professional context.
