IBC Table 1607.1 Stairways must be designed and built to support a load of 100 <br />pounds per square foot and to support a concentrated load of 300 pounds on the treads in <br />an area of 4 square inches. <br />IBC 1003.3.3.11 Handrails. Stairways are required to have handrails on both <br />sides and be attached and have adequate strength. Handrail height as measured from the <br />stair nosing shall be unifoini, not less than 34 inches or more than 38 inches. Handrails <br />must be graspable and continuous without interruption with the ends returned into a wall, <br />guard, or walking surface and have the proper 12 inch extension on the top and bottom of <br />each flight of stairs. <br />Corrective Action: Permits were not issued at the time the storage and mezzanine areas were <br />constructed, therefore all requirements for stairs, landings, guards, and handrails have not been <br />inspected and made to comply. Because approvals were not given, inspections were not done and <br />the building code complied with. Correct all violations only after submitting plans, having <br />approvals, and securing the proper permits to do so. <br />This building is deemed unsafe due to inadequate egress and is unsafe to human life. <br />Paint Booth- MSBC 1300.0120 A permit was not issued for the construction of <br />a spray paint booth. It appears the spray booth is homemade with wood framing <br />members covered with sheetrock gypsum. A support guide wire is attached to the top <br />and extends up at an angle and is attached to the bottom of the roof trusses adding an <br />additional concentrated load to the roof system. On the ceiling of the paint booth, screens <br />and filters have been inlaid to act as a filtering system for the exhaust which is a fan <br />attached to the sidewall of the booth. Round ductwork is taped to the fan to exhaust the <br />flammable vapors to the outside of the building. <br />Per Section 416, Application of Flammable Finishes, the spraying of flammable <br />paints must comply with NFPA 33 and 34. These requirements include that spray rooms <br />be enclosed by a fire wall and /or barrier with a fire resistant rating of 1 -hour. The interior <br />surfaces of spray rooms must be smooth and continuous without edges to allow the free <br />passage of exhaust air and to facilitate the washing and cleaning. Spray booths must be <br />ventilated in accordance with the International Mechanical Code. An automatic fire - <br />extinguishing system installed per the International Building Code, Chapter 9, shall be <br />provided in the spray spaces and storage rooms. <br />Corrective Action: Remove the entire spray booth and its ventilation system. If a spray paint <br />operation is planned, submit engineered details that comply with all code requirements from an <br />independently listed spray paint booth manufacturer along with a competed permit application <br />which details the installation and assembly of the spray booth and the automatic fire- extinguishing <br />system. <br />The paint booth is dangerous to human life because it is a fire hazard. <br />Plumbing- Minnesota Plumbing Code (MPC), Section 4715.2110.DD requires <br />that a hose vacuum breaker be installed to protect the potable water supply on water lines <br />- 2 5 - <br />
