How often must fixed facilities, also known as shooting rooms, be inspected to ensure warning signals are operable?

Fixed facilities, often referred to as shooting rooms, are specific areas designated for radiographic testing that require stringent safety measures. Ensuring that warning signals are operable is critical for maintaining a safe environment for personnel and the public. A daily inspection prior to use is the best practice because it allows for the immediate verification of the functionality of safety systems and equipment before any radiographic operations commence.

Conducting these checks daily helps in promptly identifying any potential malfunctions or issues that could lead to unsafe conditions. Since these facilities may be used intermittently or by different operators, regular daily inspections provide assurance that what was functional the last time might still be operational without assuming safety status. This approach includes checking not only the warning signals but also other safety equipment, thereby fostering a culture of safety and responsibility in radiographic operations.
