I hope he specified more than just ESFR.  Did he give you any specifics or has 
he left the selection of pressure and K-factor up to you?  Depending on the 
water data and what is chosen you may or may not need a pump. Hopefully he gave 
you recent water information so you don't have to guess.

ESFR would eliminate in-racks by definition but the depth of the racks and 
arrangement of the commodities may create some major shielding issues.

Thank you for the confirmation before I go to the engineer with hat in hand and 
try and explain why I can't do what he asked. I this case it means a pump.

Interesting since NFPA 13 A.5.6.3 (2007) lists foam mattresses (in finished
form) as a Group A Plastic.  Box springs which are mostly wood and metal as 
Class III.

I would consider the foam in the sofas and probably lean toward classifying 
them the same as the mattresses.

They probably looked at Furniture, with plastic coverings - Class IV.  But with 
foam plastic cushioning it's back to Group A plastics (sofas).

Somebody messed up.  Need to remind them of Sofa World.  This stuff burns fast 
and hot and flows.

You need to look at the racks again too.

I am working on a bid for a warehouse. I was given a floor plan for the new 
building and a copy of the fire plan from the same building they just finished 
in another state.

The also sent photos of the existing building.



The pics show mattress in plastic bags staked on end all lined up in a row.
Just like in dramatic burn video I recently watched.

The other area of the warehouse has couches bagged the same way. Sitting on 
12'3" bay racks.

The sprinkler plans for the this are list it as Class IV commodity protected 
with EFSR heads and no in rack system.



Even if they put the stuff back in the boxes I can't see how they a class V 
commodity

Is there some thing I am missing before I call the engineer?



Thank you for your attention.
