The process of assuring that all systems and equipment are tested and operated in a safe environment to verify the facility will operate as intended when process chemicals are introduced
Constructability
Optimum use of construction knowledge and experience in planning, design, procurement, and field operations to achieve overall project objective.
Facility
A portion of or a complete plant, unit, site, complex or any combination thereof. A facility may be fixed or mobile.
Functional Safety
Part of the overall safety relating to the process and its control system which depends on the correct functioning of the safety controls, alarms, and interlocks (SCAI) and other protection layers
Gatekeeper
Person responsible for evaluating the project deliverables at each stage gate
Inherently Safer Design
A way of thinking about the design of chemical processes and plants that focuses on the elimination or reduction of hazards, rather than on their management and control.
Lessons Learned
Knowledge gained from experience, successful or otherwise, for the purpose of improving future performance.
Mechanical Completion
Construction and installation of equipment, piping, cabling, instrumentation, telecommunication, electrical and mechanical components are physically complete, and all inspection, testing and documentation requirements are complete.
Pre-Commissioning
Verification of functional operability of elements within a system, by subjecting them to simulated operational conditions, to achieve a state of readiness for commissioning.
Project Governance
Management framework within which project decisions are made
Project Life Cycle
The series of phases that a project passes through from its initiation to its closure.
Project Risk
An event or set of circumstances that, should it occur, would have a material effect, positive or negative, on the final value of the project.
Project Scope
Work performed to deliver a product, service, or result with specified features and functions.
Quality
The degree to which a set of inherent characteristics fulfills requirements.
Quality Assurance
Activities performed to ensure that equipment is designed appropriately and to ensure that the design intent is not compromised, providing confidence throughout that a product or service will continually fulfill a defined need the equipment’s entire life cycle
Quality Control
Execution of a procedure or set of procedures intended to ensure that a design or manufactured product or performed service/activity adheres to a defined set of quality criteria or meets the requirements of the client or customer.
Quality Management
All the activities that an organization uses to direct, control and coordinate quality.
Safety Critical Equipment / Element
Equipment, the malfunction or failure of which is likely to cause or contribute to a major accident, or the purpose of which is to prevent a major accident or mitigate its effects.
Scope Creep
Uncontrolled changes or continuous growth in a project's scope
Site Acceptance Test
The system or equipment is tested in accordance with client approved test plans and procedures to demonstrate that it is installed properly and interfaces with other systems and equipment in its working environment.
Startup
The process of introducing process chemicals to the facility to establish operation.
Statement of Work
Narrative description of products, services, or results to be delivered by a project.
System
Section of a facility that can be pre-commissioned independently, but in parallel with other sections of the facility under construction.

PREFACE

The American Institute of Chemical Engineers (AIChE) has been closely involved with process safety, environmental and loss control issues in the chemical, petrochemical and allied industries for more than four decades. Through its strong ties with process designers, constructors, operators, safety professionals, and members of academia, AIChE has enhanced communications and fostered continuous improvement between these groups. AIChE publications and symposia have become information resources for those devoted to process safety, environmental protection and loss prevention.

AIChE created the Center for Chemical Process Safety (CCPS) in 1985 soon after the major industrial disasters in Mexico City, Mexico, and Bhopal, India in 1984. The CCPS is chartered to develop and disseminate technical information for use in the prevention of accidents. The CCPS is supported by more than 200 industry sponsors who provide the necessary funding and professional guidance to its technical steering committees. The major product of CCPS activities has been a series of guidelines to assist those implementing various elements of the Risk Based Process Safety (RBPS) approach. This book is part of that series.

Process safety should be a major consideration during the development of engineering projects within the chemical, petroleum and associated industries. Whether the project is a major capital project or a modification governed by management of change, incorporating process safety activities throughout the project life cycle will reduce risks and help prevent and mitigate incidents. In particular, the adoption of process safety early in the project life cycle can achieve levels of inherent safety that becomes more difficult and expensive in later design development. The CCPS Technical Steering Committee initiated the creation of this guideline to assist companies in integrating process safety into engineering projects.

This guideline book addresses process safety activities that are appropriate for a range of engineering projects, although not all activities will applicable to a specific project. It is not the intent of this guideline book to explain methodologies for the activities as these are covered in other CCPS publications. The guideline book also provides an introduction to project terminology so that process safety engineers and others can articulate the recommended process safety activities in a language that project management teams can understand.
