|During the annual condo fire sprinkler inspection, business-card-size magnet signs will be put on the refrigerators of each unit when the unit is inspected. |
The purpose of the sign is to warn residents and their guests to not hang anything from the fire sprinkler head because doing so can lead to flooding the unit and the adjacent units.
Note: If you want even more warnings around your unit, 2 inch in diameter professional-quality labels can be ordered here and placed next to the most vulnerable sprinkler heads e.g. the low ones in the bedrooms and hallways. A pack of 5 costs $14.94 including shipping.
