From basic junction boxes to overseeing the intricate control systems of complex processing plants, the contents housed within enclosures play a pivotal role in ensuring the safety of many individuals. Control enclosures found in expansive chemical plants, electrical generating facilities, airports, mass transit systems, or hospitals often contain equipment crucial to the well-being of numerous people.
Security Risks
Protection against unauthorized access, tampering, or accidental operation is a top priority, and rigorous security measures are incorporated into key locations to safeguard control equipment from unwanted access. In addition to external security measures, the enclosure's direct access is fortified through the careful selection of hinges, latches, and appropriate locking mechanisms.
Economic Impact
While the monetary value of the equipment within an enclosure may be significant in some applications, the more pressing concern is the potential economic consequences resulting from theft, vandalism, unauthorized access, or accidental operation of a control system. These consequences could have more severe implications than the intrinsic value of the equipment.
Considerations When Choosing Enclosures
The most vulnerable aspect of enclosure access is the lock, not the box, irrespective of the enclosure material. Various hinge and latch combinations are available to secure the contents of an enclosure. Though security needs may vary for each application, the selection process should encompass the following considerations:
- Some enclosures feature hidden hinges and quarter-turn latches or camlocks with security key access to provide additional security by minimizing their visibility and vulnerability.
- Access frequency is a crucial consideration. Whether an installation requires daily, monthly, or annual access is significant. Keeping unauthorized individuals out is slightly more important than ensuring that keys or tools are readily available when access by authorized personnel is urgently needed.
- Will the location or specifications necessitate a tool for opening? Are considerations like padlocks required for latches? In many cases, the hinge type is automatically chosen when selecting the enclosure, but for some enclosures, it's possible to choose the hinge or an available hinge-less option.
