B737-800 flight crew reported having to stop abruptly to avoid an emergency vehicle during taxi out....

Narrative:

Ground control issued us a clearance to taxi from spot 8 to runway 8R in mia. The instruction was to follow an airbus on taxiway M. I confirmed clear right as we began to taxi. I had the airbus insight and relayed this information to the captain since it was out of his field of vision. As we continued the taxi I verified that the captain did obtain visual contact with the airbus on taxiway M; and that was the traffic to follow. I looked again to the right to clear for traffic; this is when I saw a fire truck moving at pretty fast speed with the emergency lights flashing. The truck was moving much faster than an aircraft would normally taxi. I told the captain to stop; stop; since he could not see the rapidly approaching fire truck from the right. The captain stopped expeditiously and allowed the fire truck to pass in front of us on taxiway north. There was never a mention of the emergency vehicle from ground at any time; before or after the truck passed. Almost immediately a flight attendant called from the back and said she needed time to clean up the galley from some items that spilled from the braking. We continued a slow taxi to 8R and proceeded with normal duties. The flight attendant called back and stated she was ready. I asked if everything okay and if everything is all set; and the answer was yes. The flight continued to the destination as planned and uneventful. After the passengers deplaned; a flight attendant informed the captain that she was injured in the galley as a result of the aircraft stopping during the taxi out.emergency vehicle traffic advisories should be given to all aircraft; when they responding to an emergency. As an example: from ground control 'all aircraft use caution rescue vehicles are responding to an emergency.' a message transmitted that would be similar for windshear or new ATIS.

The captain stopped expeditiously and allowed the fire truck to pass in front of us on taxiway N. There was never a mention of the emergency vehicle from ground at any time; before or after the truck passed. Almost immediately a flight attendant called from the back and said she needed time to clean up the galley from some items that spilled from the braking.
