Isolate the air compressor media recirculation and air pollution equipment to minimize noise exposure. Hygiene Facilities. Provide change rooms and shower following guidelines such as OSHA regulations DOD or Branch Service requirements. 6-6 Simpo PDF Merge and Split Unregistered Version - http 3-410-04N 25 October 2004 CHAPTER 7 WOOD SHOP FACILITIES 7-1 FUNCTION. Wood shops differ in size and function. Use the design criteria in this chapter as a general guideline for developing ventilation systems for wood shops. 7-2 OPERATIONAL CONSIDERATIONS. A properly designed ventilation system will control the dust level within the shop. Exposure to wood dust may lead to health problems. The accumulation of wood dust can create explosion and fire hazards. Even if a ventilation system is installed to collect most of the dust manual cleaning at each machine and throughout the shop is still necessary. Restrict woodworking exhaust systems to handling only wood dust. Do not connect any other process that which could generate sparks flames or hot material to a woodworking exhaust system. 7-3 FLOOR PLAN LAYOUT. Contact the shop personnel who will be working with the machinery to get their input on workflow and specific equipment. Design the ventilation system to complement equipment layout and minimize housekeeping. 7-4 DESIGN CRITERIA. Design the facility using general technical requirements in Chapter 4 of this UFC NFPA 664 Prevention of Fires and Explosions in Wood Processing and Woodworking Facilities and the specific requirements in this chapter. Exhaust Air System. Calculate the system capacity on the basis that the system operates with all hoods and other openings such as floor sweeps open. Refer to the ACGIH IV Manual Chapter 10 for determining the exhaust flow rate for specific wood shop machines. .
