Overview
- South Yorkshire Fire Service used its official TikTok account to say the yellow H markers point to fire hydrants.
- The large number at the top of each sign shows the diameter of the water main in millimetres.
- The smaller number at the bottom shows how many metres the hydrant is from the sign.
- Some signs include an arrow that points toward the hydrant to speed locating it.
- The service said hydrant locations also appear on crew data terminals for use during callouts.
