To contain warnings after several studies that have shown they are a suffocation risk, the following measures could be implemented for each:

1. Wireless technology: Manufacturers can design and include warning labels on wireless devices, packaging, or user manuals indicating the potential suffocation risk associated with specific components or usage patterns. Additionally, public awareness campaigns can educate users about the potential hazards and recommend safe practices.

2. DDT: DDT (dichlorodiphenyltrichloroethane) is an insecticide that has been banned in many countries due to its harmful effects on human health and the environment. However, if there were studies indicating a suffocation risk, the warning labels would be necessary on the packaging or containers of products containing DDT.

3. Plastics: Certain types and forms of plastics, such as plastic bags or small plastic pieces, can pose a suffocation risk, especially to children. To address this risk, packaging manufacturers can include explicit warnings on plastic bags, packaging materials, or plastic products that may cause suffocation if not handled correctly or kept away from young children.

4. Vaccines: Vaccines are typically administered through injections and would not typically pose a suffocation risk. However, if there were any concerns related to suffocation risks associated with vaccines (e.g., improper storage or disposal), appropriate labels or instructions would be required on vaccine packaging or information materials to ensure safe usage.

It is important to note that the suffocation risk associated with these items should be supported by thorough scientific studies conducted by reliable research institutions or regulatory agencies before mandatory warnings are implemented.
