Should the fire sprinkler pipe without ceiling be painted?

It is best not to replace the fire sprinkler without permission. This equipment is protected by fire protection law. The existing state should also be checked and accepted by the fire department when handing over the house. Painting without authorization may block the nozzle, or it may not be eye-catching, which is not conducive to future fire fighting work. If you really have opinions, you can also communicate with the fire department through the property and make reasonable changes under their supervision or guidance.
