Chemical process quantitative risk analysis (CPQRA) as applied to the CPI was first fully described in the first edition of this CCPS Guidelines book. This second edition is packed with information reflecting advances in this evolving methodology, and includes worked examples on a CD-ROM. CPQRA is used to identify incident scenarios and evaluate their risk by defining the probability of failure, the various consequences and the potential impact of those consequences. It is an invaluable methodology to evaluate these when qualitative analysis cannot provide adequate understanding and when more information is needed for risk management. This technique provides a means to evaluate acute hazards and alternative risk reduction strategies, and identify areas for cost-effective risk reduction. There are no simple answers when complex issues are concerned, but CPQRA2 offers a cogent, well-illustrated guide to applying these risk-analysis techniques, particularly to risk control studies. Special Details: Includes CD-ROM with example problems worked using Excel and Quattro Pro. For use with Windows 95, 98, and NT.NFPA 68 (NFPA, 1994) also gives a cubic law relating rate of pressure rise to vessel volume in the form 711a#39; KG OIa#39;KSr =Vaquot;3(;) (2.2.50) where KG is the characteristic deflagration constant for gases and K5! is the characteristic venting constant for dusts. The a€œSta€ subscript ... The NFPA 68 guide (NFPA, 1994) also lists tables of experimental data for gases, liquids, and dusts that show Pma€œ and dP/dt.
