Automatic line leak detectors must be tested at least ______.

• A. daily
• B. weekly
• C. monthly
• D. no daily or month

Answer: (D)

Testing automatic line leak detectors is about confirming they respond correctly and that alarms work, on a schedule set by the manufacturer or the site’s procedures. These devices are not meant to be checked daily or monthly as a minimum requirement; the proper interval is defined by the device’s design and local safety standards. So the idea is that there isn’t a need for a daily or monthly minimum test; follow the manufacturer’s instructions or your SOP for the appropriate maintenance interval.
