Foreword
ISO (the International Organization for Standardization) is a worldwide federation of national standards
bodies (ISO member bodies). The work of preparing International Standards is normally carried out
through ISO technical committees. Each member body interested in a subject for which a technical
committee has been established has the right to be represented on that committee. International
organizations, governmental and non-governmental, in liaison with ISO, also take part in the work.
ISO collaborates closely with the International Electrotechnical Commission (IEC) on all matters of
electrotechnical standardization.
The procedures used to develop this document and those intended for its further maintenance are
described in the ISO/IEC Directives, Part 1. In particular, the different approval criteria needed for the
different types of ISO documents should be noted. This document was drafted in accordance with the
editorial rules of the ISO/IEC Directives, Part 2 (see www .iso .org/directives).
Attention is drawn to the possibility that some of the elements of this document may be the subject of
patent rights. ISO shall not be held responsible for identifying any or all such patent rights. Details of
any patent rights identified during the development of the document will be in the Introduction and/or
on the ISO list of patent declarations received (see www .iso .org/patents).
Any trade name used in this document is information given for the convenience of users and does not

This third edition cancels and replaces the second edition (ISO 10418:2003), which has been technically
revised. It also incorporates the Technical Corrigendum ISO 10418:2003/Cor.1:2008. The main changes
compared to the previous edition are as follows:
— safety analysis tables (SATs) and safety analysis checklists (SACs), which previously were reproduced
from API RP 14C, have been deleted and replaced by references to the analysis methods included in
API RP 14C;
— simplification of annexes to avoid duplication of API RP 14C content.
Any feedback or questions on this document should be directed to the user’s national standards body. A

Introduction
Effective management systems are required to address health and safety aspects of activities
undertaken by companies associated with offshore recovery of hydrocarbons. These management
systems are applied to each stage in the lifecycle of an installation and to related activities.
One key aspect of effective management systems is a systematic approach of identification of hazards
and the assessment of the risk, in order to aid decision-making on the need for risk-reduction measures.
Selection of risk-reduction measures entails the use of sound engineering judgement informed
by recognition of the particular circumstances, which can prompt variation to past practices and
previously applied codes and standards.
Risk reduction measures include those to minimize and eliminate hazards by design (i.e. use of
inherently safer designs), to prevent incidents (i.e. reducing the probability of occurrences), to control
incidents (i.e. limit the scale, intensity and duration of a hazardous event), and to mitigate effects (i.e.
reducing the consequences).
Extent of hazard identification and risk assessment activities will vary depending on the stage in the
installation lifecycle, as well as process conditions, degree of standardization, complexity, number of
persons on board and the installation’s overall estimated level of risk.
For installations in the early design phases, the evaluations will necessarily be l
