In explosion and flash fire incidents, electrical arcs and electrostatic sparks are often considered to be primary ignition sources, because they are “everywhere” and can have sufficient energy to ignite most flammable gases, vapors and dusts. However, there is a wide variety of other types of ignition sources that must be considered. Mechanical equipment is commonly found in manufacturing sites and can present a significant non-electrical ignition hazard. Hazardous Area Classification, to manage selection and installation methods of electrical devices, traditionally only addresses the ignition hazard of electrical equipment. Mechanical equipment often contains bearings and rotating parts that can cause frictional heating and frictional sparks during routine operation or during equipment-upset conditions. To identify – and eliminate or control – these types of ignition sources, an analysis method that is described as a “Mechanical Equipment Ignition Risk Assessment” [MEIRA] can be used.
Join us for Understanding Mechanical & Electrical Ignition Sources. During this informative presentation, we will discuss:
Mechanical Ignition Sources
Their energy potentials
The likelihood and risk of ignition from each of these sources.
Category 1, 2 and 3 equipment as it relates to Mechanical Ignition Sources
How to perform a Mechanical and Electrical Ignition Risk Assessment (MEIRA)
Process Safety Information required for a MEIRA
How to properly document the MEIRA to serve as an aid in future assessments and Management of Change
