Final answer:
If the opening code signal at the bank has not been activated, one should stay outside and contact a supervisor or security for further instructions. Following established security procedures is critical for personal safety and the security of the bank.
Step-by-step explanation:
If you arrive for work at the bank and notice that the opening code signal has not been activated, the first course of action should be to stay outside and contact a supervisor or bank security. Do not attempt to enter the premises until you have received proper instructions.
Financial institutions have strict security protocols to ensure the safety of employees and customers. The absence of an opening code signal could indicate a security breach or operational error. In such scenarios, it is imperative to follow established emergency procedures, which typically include avoiding entering the building, reaching out to a manager or security personnel, and waiting for them to resolve the situation or give the green light to enter.
Ignoring the protocol could endanger personal safety or disrupt the investigation and resolution of the potential security issue. Always adhere to the safety guidelines provided by your employer to handle such situations professionally and securely.
