Keep it.  Fixed hoses are quite common in large buildings.  However,
like most indoor features, they're not mapped very often.

This is an emergency=landing_site: it's a section of parking lot that's

This is an aeroway=helipad: it's a dedicated helicopter landing area,
designed and marked as such.
