FIREPRROOFING TIMBER STRUCTURES
FIREPRROOFING TIMBER STRUCTURES
(OP)
WE HAVE AN OLD MILL (TIMBER)STRUCTURE AND THE OWNER WOULD LIKE TO USE THE SECOND FLOOR FOR MISC. METALS FABRICATION SHOP. TO FIREPROOF AND PROTECT THE WOODEN FLOOR AND THE BEAMS BELOW THEY ARE THINKING OF PLACING A LIGHT WEIGHT CONCRETE SLAB OVER THE HARDWOOD FLOORS. DOES THIS PRESENT A FIRE HAZARD PROBLEM? IS THERE ANOTHER WAY TO FIREPPROOF THE HARDWOOD FLOOR AND TIMBER BEAMS BELOW?
ANY INFORMATION WOULD BE GREATLY APPRECIATED

I can see where the Client maybe worried about welding slag getting in the wood timber joints. Most likely you don't need to fireproof the structure per code requirements.
The problem with adding concrete is that the subsequent mass becomes a seismic consideration. By adding this mass to the structure, the code requires that the structure be able to resist the resultant seismic force. Most timber mill buildings were not designed for seismic at all.
Look for something lighter that will not burn. Maybe checkered plate in localized welding areas? Gypcrete may also be an option.
Are the beams and flooring above being hit by metal embers or slag? If so a layer of fire coded gyp board will help.
Good luck, let us knonw what you decide.
