In regards to life safety building has smoke detection in all areas, travel distances are comfortably within the guidelines (only 7 rooms on 1st floor of 2 storey building),strictly no smoking, robust PAT testing and new wiring in place, good fire management with training, fire drills etc. I am looking from more of a property safety aspect than life safety. Obviously this would not be a all singing and dancing fire door due to not being tested to BS476, but would increase the fire protection that is currently in place. Also with the owners still wanting to retain the original features and doors, would applying intumescent coating and ensuring doors have/can self close be sufficient. Where a period building has been converted to sleeping accommodation, would it not be responsible to upgrade the ceiling to 60 minutes fire resistance using intumescent systems so to protect fire reaching the big timber roof void and basically end of building and ensure containment if fire developed in sleeping room (sneaky fag by a drunken Union Rep). Is there any research material on fire test conditions and results? The 9mm JHP pistol round penetrated all three walls and exited the "house".Lath and plaster in good condition can provide 20 minutes fire resistance?. JSP round penetrated the first wall, leaving a ½ inch hole on the back side, and did not strike the second wall. In other words, the bullet was trapped in the second wall. FMJ carbine round fully penetrated the first wall and a fragment of that bullet penetrated the front of the second wall without exiting the rear. The slug and 00 buckshot loads penetrated all three walls and exited our "house". The second wall was speckled with a few pellets but none penetrated or stuck in the wall. The birdshot round penetrated the first wall, producing a fist-sized hole. jacketed hollow point, fired from a full size S&W M&P 9 pistol. We finished with a typical 9mm round, a 147 gr. These were fired from a 16" Colt LE6940 carbine. From a distance of about 21 feet from the first wall, we fired a round of birdshot (#7 ½), a 9 pellet 00 buckshot load and a one ounce slug into the wall. We're also trying to dispel some myths, as there are a number of common misperceptions concerning what different ammunition will actually do under these circumstances. The ideal ammunition would be that which would be effective against a bad guy but not likely to penetrate numerous walls, thus endangering others in the house or outside of the home. What we're trying to do here is test ammunition and demonstrate what might be best for use in a home defense situation. The walls are in a line so that we can shoot the first wall and then check for penetration across our "rooms" and into or through the remaining walls. Next we space the walls out to about 21 feet apart, which might simulate the average distance across a room in a typical home. We use wallboard, insulation and exterior siding. In a wall test we build three walls, two interior and one exterior, as might be found in a typical home. Recently we have had the opportunity to set up some wall tests and we thought you might be interested in the results. From the latest Gunsite newletter, ( posted with Ed Head's permission:
