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

Introduction
Workers in the petroleum and natural gas industries face a number of stressors from the physical and
psychosocial environment when working in the Arctic. These include prolonged periods of darkness
(polar winter) and light (polar summer), remoteness, noise and vibration, low humidity and cold
climate. The combination of different working environment factors can affect people's health and safety.
Cold-climate locations, low temperatures and wind can directly affect both equipment (e.g. operability,
reliability and integrity) and people (e.g. frostbite, hypothermia and performance decrement). In turn,
affected equipment can affect the health and safety of personnel, and poor personnel performance
can likewise have a detrimental effect on equipment. It is important to consider and assess all
these relationships in order to have confidence in production and health, safety and environmental
(HSE) risks at facilities in cold climates. This is illustrated in Figure 1. Based on the outcome of the
assessment, approaches for cold-climate risk management should address all aspects of winterization,
from prevention through facility design and specification through to working procedures. In addition
to this, personal protective equipment (including clothing) may be necessary.

Petroleum and natural gas industries — Arctic operations
— Working environment
1 Scope
This document describes the working environment that can be expected when operating oil and gas
facilities in Arctic environments/climate. This document provides principles and generic guidelines for
the design and operation of fixed and floating oil and gas facilities both onshore and offshore.
The aim of this document is to ensure optimal health, safety, human performance and decision-making
conditions for people working on oil and gas facilities in Arctic conditions.
This document applies to the design and operation of new facilities and structures, and to modification
of existing facilities for operation in the Arctic environment. This also includes offshore and onshore
exploration and accommodation units for such activities.
This document is divided into three main parts.
— The first part (Clause 5) describes the general principles and guidelines for risk management.
— The second part (Clause 6) describes the general working environment (working environment
hazards found in many workplaces and provides some threshold limit values (TLVs) and design
references that can be especially challenging in Arctic conditions.
— The third part (Clause 7 to Clause 9) addresses the climatic conditions expected in the Arctic.
Clause 8 describes working environment design and technical solutions, while Clause 9 describes
working environment operational requirements for prevention and management of cold-related
problems.
