Going back a long while I worked for a number of years with the Michelin Tyre Company. Sprinkler protection was always direct onto racks and within them. Within their warehousing they did not allow mezzanine storage as you describe here. The trouble is when a fire takes hold with rubber (Tyres) you cannot stop it. In discussions with the Fire Brigade, it was admitted that all they could realistically do in the event of an established fire, was to contain the spread and let what was alight burn out. It is not worth the risk to rely on open grating and water getting through, I agree with Craig.

Just base it in what it is - 8'-0 high rack storage for tires on tread in fixed open racks? Bobby Gillett Sr. Project Manager Key Fire Protection, Inc.

So basically the racks extend up through holes left in the mezzanine?

The mezzanine is open grating They say the "dead tires" will be stored outside. You are exactly right - the EOR shows ESFR at the roof and nothing below the mezzanine. I guess they figure since the rack is constant and the flue space is open that the tires are covered and since the mezzanine is open grating that no protection is required below. I disagree and was curious how others thought under the mezzanine should be applied/protected. Bobby Gillett Sr. Project Manager Key Fire Protection, Inc.

Is the mezzanine open grating? Also, is there a room for dead tires? Reason I ask is that my son works for a national chain and they have a mezzanine with probably 300-500 tires stored on end, on racks. Below the mezzanine at grade level there are also tires stored in the same manner. There is also what is called "the dead room" which is where old tires are stored until they are picked up by the recycler. The dead room has above 8 ft ceilings with tires stacked on their sides up to within a foot of the ceiling. The dead room is sprinklered as is the roof over the upper level of rack storage however the tire storage rack below the mezzanine is not protected. Apparently the EOR figures that since it's open grating that the water will run down from above. DUMB assumption but common....... Kicker is, all this was approved by the local AHJ And FD. Craig L.
