EEMUA 186 offers guidance for safe installation, inspection and maintenance work in potentially explosive atmospheres when the failure to adopt safe working practices could result in the ignition of flammable gases or combustible dusts. It is concerned with ignition caused by electrical and mechanical sources and is based on the requirements of international and European standards, directives and regulations.

This seventh edition has been further updated to align with the latest versions of the relevant standards, in particular the fifth (2013) editions of IEC 60079-14 and 60079-17. EEMUA 186 interprets the relevant parts of the standards, and brings them together in one clear, understandable and easily navigable resource. The chapters on equipment, installation and inspection have been revised extensively, including EEMUA’s recommendations on barrier gland selection. There are separate chapters on: fuel filling stations; hazardous areas in the water and waste water industries and mechanical ignition sources. Application design engineering and the duties of the Responsible Person as defined in IEC standards are also covered.

Potentially explosive atmospheres occur in many industries, not only in onshore and offshore oil and gas, but also in chemicals, power generation, pharmaceuticals, food and beverages, manufacturing, martime and utilities. Typical sites include petrochemical processing and refining plants, liquor distilleries, paint spraying plants, flour mills, woodworking plants and coal handling plants. 

EEMUA Publication 186 is closely associated with the CompEx® training and competency assessment scheme which provides trainees with essential knowledge and practical skills for safe working in potentially explosive atmospheres.

EEMUA offers introductory e-learning in the areas of Alarm Systems, Control Rooms, Cyber Security and Functional Safety.

Ex e-learning at the awareness level. 
EEMUA recommends IntroEx, a free to use knowledge and awareness tool from CompEx Certification Limited, the CompEx Certification Body. It provides users with an overview of some of the basic principles of explosive atmospheres and takes approximately 20 minutes to complete.
