Which is true about statements of practical treatment?

The correct choice highlights that all DANGER labels indeed contain a note to physicians describing appropriate medical procedures. This is essential because these labels indicate a high level of toxicity and potential harm from the pesticide. Including a note to physicians allows them immediate access to vital information about the substance, which is crucial for effective treatment in the event of pesticide poisoning. This adherence to safety practices helps ensure that medical personnel can provide prompt and accurate care to those exposed.

In contrast, the other options do not hold true in this context. For instance, statements about inducing vomiting may not be included on all labels, particularly those that might instruct against it due to potential complications. Additionally, statements of practical treatment are closely associated with signal words, as these words indicate the severity of hazards and the appropriate response measures. Lastly, having the pesticide label available during a poisoning emergency is critical because it provides essential information regarding the product's active ingredients, risks, and specific first aid measures, enabling a more effective response.
