Minimize structural and mechanical damage with NFPA 68's critical guidance on the design, location, installation, maintenance, and use of devices and systems that vent combustion gases and pressures resulting from a deflagration within an enclosure.

Just revised for 2002, this Guide features reorganized chapters, with separate chapters for combined dust guidelines, and all gas and vapor guidelines. Revised design equations for venting of deflagrations involving dust mixtures were created through more accurate models of explosion phenomena. In addition to the equations, the Guide now provides graphical solution options. (Approx. 64 pp. 2002)
