A suitable place for the storage of samples must be__________?

A suitable place for the storage of samples must be locked to ensure their security and integrity. Locking the storage area helps prevent unauthorized access, contamination, or tampering, which could compromise the quality and reliability of the samples. Protecting samples from unintended exposure to environmental factors, unauthorized individuals, or accidental handling is essential in maintaining their validity for testing and analysis.

While accessibility is important to ensure that authorized personnel can retrieve samples as needed, it must be balanced with the need for security. Proximity to the weighing station can be beneficial for efficiency, but it does not address the primary concern of safeguarding the samples. Storing samples in an open container can lead to contamination and degradation over time, making a controlled, locked environment a crucial requirement for proper sample storage.
