Final answer:
The given question about the necessity of a complete copy of the label at mix and load sites cannot be accurately answered due to a lack of relevant context and supporting information provided.
Step-by-step explanation:
When handling substances at mix and load sites, it is crucial for safety and regulatory compliance to have proper documentation on hand. The question addresses whether a complete copy of the label must be available at both the mix site and the load site. If this were a true statement, it would typically relate to following guidelines for the handling of chemicals, possibly in an agricultural, landscaping, or pest control setting.
However, as the information provided does not directly pertain to the question about labels and instead references a scenario about displacement, it seems there may have been a mix-up in the information given. Without the correct context or reference, it would be challenging to confidently provide an accurate answer to the question regarding label requirements. Therefore, we will not offer a definitive true or false without the correct context.
