What type of envelope should spare pharmacy keys be kept in?

Spare pharmacy keys should be kept in a tamper-evident envelope to ensure security and accountability. This type of envelope is designed to show visible signs if it has been opened or altered, which helps to protect sensitive items like keys that grant access to controlled substances and secure areas within the pharmacy. The use of a tamper-evident envelope provides an additional layer of security, ensuring that only authorized personnel have access to the keys.

Tamper-evident envelopes are particularly important in pharmacy settings due to the potential for misuse of medications and the need for strict compliance with regulations concerning drug storage and access. By keeping spare keys in such an envelope, pharmacies can better control access and demonstrate adherence to safety protocols.

Other options, while they may provide some level of protection, do not offer the same assurance that the envelope has not been tampered with. For example, a plastic bag might not show if it has been opened, a paper envelope lacks the features to indicate tampering, and a metal container, while durable, would also not provide a clear indication if someone unauthorized accessed the keys.
