Terminals installed directly under a fan

Multiple signals dropping out, no obvious cause. Pulled the covers and found it straight away. Dust being blown directly into the terminals, constantly. Every time that fan runs, it's packing debris into the connections. Not a fault with the signals. Not a fault with the wiring. A fault with where someone decided to put the terminals in the first place. Common sense isn't always common. The fix for the signals was straightforward. Getting someone to relocate those terminals properly is the actual job.
