P. Stavrianidis et J. Rennie, IMPROVING MANAGEMENT OF TECHNOLOGICAL RISK - RELIABILITY CERTIFICATION OF SAFETY SYSTEMS, ISA transactions, 35(2), 1996, pp. 127-136
This paper discusses a Process Safety Compliance Framework (PSCF) used
to evaluate process risk consistently and systematically. The PSCF as
sesses the compliance of the process to existing standards and provide
s opportunities to improve the management of technological risk. An es
sential element of the PSCF is a Reliability Certification Program. Th
e certification program assesses the reliability of safety products an
d systems employed within the PSCF to reduce process risk to manageabl
e levels, The Process Safety Compliance Framework relies on a Comprehe
nsive Process Safety Assessment and Lifecycle Model (CPSALM), which id
entifies the process safety target level, or alternatively the process
risk profile, The model evaluates the safety level attributed to exis
ting safety systems (safety layer) and assesses the effectiveness of p
rocess improvements that are required to meet or exceed the process sa
fety target level. This target is determined by examining the complian
ce of the process to industry, jurisdictional and company specific sta
ndards. The CPSALM is applied to several systems performing the same f
unction and using different technologies. The performance of these sys
tems is compared using reliability as the selection criteria. The appr
opriate system is then introduced into the PSCF to assess the process
risk. Copyright (C) 1996 Elsevier Science Ltd.
