This three-day training course will provide delegates with training on the Energy Institute Model Safe Code of Practice 15, Area Classification for Installations Handing Flammable Fluids (EI15). This internationally recognised publication provides methodologies for carrying out Hazardous Area Classification (HAC) studies on installations where flammable fluids are processed, stored or handled.

About Hazardous Area Classification

HAC is the assessed division of a facility where releases of flammable liquids and gases can occur, either intentionally or accidentally, into hazardous areas and non-hazardous areas. The EI15 guidance is relevant to all industry sectors where the classification of potential flammable zones is a requirement.

In this course, delegates will learn how to identify areas where flammable zones can arise and how to subsequently control these ignition sources, a fundamental strategy to any organisation’s process safety management.

Key benefits of the Energy Institute’s Hazardous Area Classification training:

  • The course is based on the Energy Institute’s renowned EI15 guidance document
  • Receive a free copy of the EI15 guidance document (worth £160)
  • Learn from an expert tutor, who was involved in the production of the EI15 guidance and has extensive experience of carrying out HAC studies for many companies in a wide variety of industry sectors
  • Delegates will receive a Hazardous Area Classification training certificate from the Energy Institute.

Learning outcomes:

  • To understand the methodology in the EI15 guidance
  • To be capable of applying the EI15 guidance in practice
  • To know when to use the EI15 guidance for relevant applications.

Who is the training for?

  • This course is suitable for anybody who is involved with process safety such as: risk analysts, chemical, mechanical and design engineers
  • Delegates should have a basic understanding of flammable products, area classification techniques and relevant standards and guidance.

Course Outline:

Introduction to legislation and standards

  • Delegates will be introduced to the statutory requirements for HAC in the UK and internationally.

 Properties of flammable materials

  • Delegates will learn about the properties of materials and their flammable and combustible characteristics.

 Key area classification concepts

  • Minimum volumes for the application of HAC
  • The definition of the grades of release
  • The relationship between the grades of release, ventilation and the resulting zone
  • The concepts of blanket and point zones
  • The procedures and methodology in carrying out a HAC study.

Techniques of area classification

  • Point Source approach - Covering sample points, atmospheric vents, pig launchers and pools of liquids
  • Risk Based approach - How the Risk Level of an installation can be determined. The use of hole sizes in determining the zone 2 extents from secondary releases from pumps, pipework and compressors etc
  • Direct Example approach - Particular attention will be given to storage tanks, road tanker operations and offshore well heads. How Direct Examples can incorporate the Point Source approach.

Ventilation

  • Delegates will be introduced to the fundamental change in EI15 on the effect ventilation has on releases. Its influence on zones will be considered in diluting releases both outdoors and inside enclosures.

Impact of external variables to area classification­­

  • Throughout the training course, delegates will be familiarised with the effects of changes to external variables. The delegates will learn how the application of the direct examples and the risk based approach will change depending on the ambient or storage temperature and the resulting change in petroleum class or fluid category.

Throughout the course, there will be the opportunity for the delegates to practice the techniques on a real world example. A detailed practical exercise will be completed to reinforce the learning from each section of the training. This practical element will help translate the learning into a real world scenario.
