If you are the first staff member to arrive at work, what should you do regarding security?

The most appropriate action to take when you are the first staff member to arrive at work regarding security is to be aware of your surroundings while entering the building. This ensures that you remain vigilant and attentive to any potential threats. Being aware of anyone around you as you input the security code adds an extra layer of safety, as you can detect if someone seems suspicious or poses a risk.

This approach emphasizes personal safety and situational awareness, which are critical in potentially vulnerable situations, such as being alone in an office building. It allows you to assess the environment and respond appropriately to any unusual circumstances before proceeding further.

In this context, other choices may introduce unnecessary risks or are not practical responses in a security situation. Waiting for another staff member before entering can delay operations and does not enhance security; calling the police for a forgotten code is excessive and could compromise safety, and entering despite evidence of forced entry can put you directly in harm's way.
