What type of information do precautionary statements typically contain?

Precautionary statements are designed to communicate important safety information regarding the hazards associated with a product. They provide specific guidance on how to handle, store, or dispose of the product safely, which directly pertains to the potential risks it poses to humans and animals. These statements are crucial in ensuring that consumers and handlers are informed about any potential toxic effects or hazards, thereby promoting safety and preventing accidents or health issues.

In contrast, the other types of information listed do not fall under the domain of precautionary statements. For instance, details on how to increase product efficiency are related to product performance rather than safety. Product pricing is focused on the financial aspect and has nothing to do with the safety or health risks of the product. An ingredients list is important for understanding what a product contains but does not specifically address the precautionary measures needed due to potential hazards. Thus, the emphasis on hazards to humans and animals is what makes that answer the most appropriate choice regarding precautionary statements.
