Final answer:
A pesticide must always be locked in a compartment or maintained by a licensee unless it is properly labeled and clearly marked as poison.
Step-by-step explanation:
The statement is true. A pesticide must always be locked in a compartment or maintained by a licensee unless it is properly labeled and clearly marked as poison. This is to ensure that access to the pesticide is limited only to those who are authorized to handle it and to prevent accidental poisoning or misuse. Locking the pesticide in a compartment or maintaining it by a licensee helps to protect people and the environment from potential harm.
