When passing through an access-controlled door, individuals must take several essential security steps to ensure the door is fully secured behind them, thereby preventing unauthorized entry and maintaining physical security. Adhering to these user best practices is critical for safeguarding premises and protecting everyone within. These security protocols enhance the effectiveness of any access system.
The primary security step is to visually and physically confirm the door has completely closed and latched. Do not assume the door will simply close itself. Users should gently push or pull the door after passing through to verify the latch engages fully with the door frame. This simple action helps prevent the door from remaining ajar, which could create an unsecured entry point and allow unauthorized access. This verification is vital for robust door security.
After ensuring physical closure, listen for the audible click, whir, or hum that indicates the locking mechanism has successfully engaged. Many access-controlled doors, whether using a card reader or keypad, also provide clear visual feedback. Look for a green light, an LCD message confirming “locked,” or a similar indicator that signals the door is securely fastened. These visual and auditory cues provide crucial confirmation that the access system has properly functioned, reinforcing secure access.
A critical best practice for preventing unauthorized entry is actively preventing tailgating or piggybacking. This occurs when an unauthorized person attempts to follow closely behind an authorized individual to gain access without presenting their own credential. Users must always turn around and ensure no one enters immediately after them without proper authorization. Politely, but firmly, remind individuals they must use their own access card or entry method to gain entry. This vigilance is paramount for maintaining the integrity of the security measures.
Finally, never prop open an access-controlled door, even for a short period. Propping a door completely defeats the purpose of an access system and creates a significant security vulnerability. If an access-controlled door fails to close properly, does not latch, or the locking mechanism does not engage after you have used your credential, it is essential to report the issue immediately to facility management or security personnel. Prompt reporting of any door security malfunctions ensures timely repairs and upholds the integrity of the physical security system, reinforcing overall security awareness and safety procedures for all authorized personnel.
