INSTALLING FIRESTOP SYSTEMS OR FIRE CAULK?’s latest issue has an excellent artcile about whether or not to choose firestop systems or fire caulk:

MANY HAVE HEARD ABOUT ‘FIRESTOP.’ WAIT, WHAT? WHAT’S FIRESTOP? Firestop is a tested and listed SYSTEM. The SYSTEM comes from the many fire tests conducted at leading laboratories like FM Approvals, Intertek or Underwriters Laboratories. The manufacturers of these materials invest a lot of money and time ensuring that they—the materials— in fact, work for the specific application and required time, based on proven fire test procedures, such as ASTM E 814 and UL 1479 for penetrations and ASTM E 2307, ASTM E 2837, ASTM E 1966 and UL 2079 for joints. Therefore, firestopping should be all about listed, classified firestop SYSTEMS. The SYSTEMS are an assemblage of materials—the floor or wall assembly, annular space or joint size, type, size of penetrating item and possible coverings that have been tested for a particular application, a particular hourly fire-resistancerating and/or smoke-resistant property. The SYSTEMS are then listed and classified by FM Approvals, Intertek or UL, and/or other credible independent third-party testing labs. Now we come to the installation of these firestop systems, and it seems that despite the hundreds of millions of dollars invested by the manufacturers in testing, that some in the industry continue to refer to it as, “we installed the fire caulk, so the floor and wall are now rated.” Really? There’s a magic product that provides fire-ratings?

Food smells coming from basement?

range-hood-bgeraserturds asks:

I tried a couple searches and nothing really seems to fit my situation.

There are tenants that live in the basement and every time they cook, the smells come up in to the main floor. I think the smell is making it’s way through cold air return in to the basement straight up to the cold air return on the main floor.

Is there anything I can do to stop this? It can be pretty strong at times.

Answer: I would think the smell is wafting through the floors. Each apartment should have individual heating/Ac units and should have their own returns and should not be tied together. A range hood vent outside over the stove might help reduce the odor.

Is this as bad as it looks? Mold in apartment A/C vent

r63idkvUser RobotDrZaius writes:

I took off the vent cover because I was trying to close it and the switch was stuck. Looks like death inside. Now, I’ve lived in this apartment with my g/f for almost 6 months with no health or respiratory problems…is this as awful as it looks to my untrained eye? Should I contact my apartment’s maintenance people or just clean it myself (wearing a dust mask, of course)?

zeimbo answered: It’s hard to tell from the pic- your best bet would be to get a spore test kit which most hardware stores will have relatively cheap. I would not attempt to do anything to the insulation as it may contain asbestos. If the kit comes back positive for mold spores, keep your receipt and tell the management you’d like to be reimbursed and have it cleaned..
