A pictures tells a dozen GUIDEWORDS

July 1, 2017

HAZOP has served us well for over 40 years and the familiar guidewords proposed by Lawley (1974) have been applied in countless studies and formed the basis of IEC 61882:

  1. NO or NOT

  2. MORE

  3. LESS

  4. AS WELL AS

  5. PART OF

  6. REVERSE

  7. OTHER THAN

  8. EARLY

  9. LATE

  10. BEFORE

  11. AFTER

  12. Other

However HAZOP/PHA worksheets should not just be "fill and forget" but could provide valuable components in a barrier based risk management system to sustain integrity throughout an assets lifecycle.

I'll be presenting a series of webinars hosted by CGE in Jul & Aug on the topic of HAZOP to BowTieXP to show how data in archived or current studies can be visualised in bowties with less effort/errors than simply copying & pasting and to highlight (perhaps previously unknown) safeguard imbalance and dependency.
