firewall penetration

(OP)
Am involved in installing structured cabling in renovated elementary school.  We are suppossed to install a sleeve in a four hour rated block firewall.  1. Can we do this?  2. What is largest diameter penetration allowed?

RE: firewall penetration

You can apply "Chartek" on the surface of the wall.  "Chartek" is a exposy material,which foams up into thick insulation material when heated up.  It has been tested and approved for offshore application use against hydrocarbon fire for up to 2 hours (H120 rating), it probably last much longer in cellular fires, which is much less severe.  Try talk to them.    

Nu-chem is the other company making the similar product.  

RE: firewall penetration

You can put whatever size penetration you want through that wall so long as you seal the hole when you're done with a UL-listed 4-hour firestopping product such as those mentioned by SooCS.
