What conditions must be met for an approved safe in a pharmacy?

For a pharmacy's approved safe, it is essential that the safe is immobile and anchored to the building structure. This requirement is in place to ensure the maximum security of controlled substances and prevent unauthorized access. By being immobile, the safe deters thieves from easily removing it from the premises, significantly enhancing overall security.

Additionally, anchoring the safe to the building structure means that it cannot be moved without considerable effort and the proper tools, thereby further protecting the drugs and reducing the risk of theft. This requirement aligns with the regulations set forth to ensure that pharmacies maintain a secure environment for storing pharmaceuticals, especially those that are classified as controlled substances.

Other options discuss weight and mobility of the safe, which do not align with the key security principle of preventing movement and ensuring that the safe remains a fixed, secure part of the pharmacy's infrastructure.
