It is a red zone and is used for fire trucks in the use of an emergency. Parking in one is highly illegal and you'll get an expensive ticket, so avoid it, even if you "were only gone two seconds."

parking
Yellow curbs generally imply that area is designated as a loading & unloading parking area.
A yellow curb generally indicates the area is a bus stop. You may not stop or paqrk in this area except to pick up or discharge a passenger (providing you are not preventing a bus from pulling in or out of the bus top). In NYC, the painted curbs are more advisory than anything else - it means that there is some traffic regulation in effect there. The traffic law is guided by the signs or other indicators mounted on poles at or near the curb. So even if the curb isn't painted, the signs are what you have to obey. Example: the curb in front oif a fire hydrant is usually painted red (or some shade of red). It means that you cannot park within 15 feet on either side of it. Also note that a lack of a sign (they can come off the pole sometimes) does not mean that the regulations can be ignored. Lately the City has been painting the areas at the corners of a block in yellow on either side of the curb cut (done so that wheelchairs can get on and off the sidewalk). This is done as a visual signal to pedestrians that there is a curb cut there.
In Ca. it means a loading zone for passengers or mail. In Az. is means unrestricted parking unless otherwise posted.
