Non-electrical equipment is commonly used in the handling and processing of flammable liquids, gases and powders in process industries. Typical equipment includes fans, rotary airlocks, pumps, reactor agitators, screw conveyors, bucket elevators, etc. Such equipment items can generate sources of ignition for flammable atmospheres. Hazardous Area Classification traditionally only addresses the ignition hazard of electrical equipment and is used to manage selection and installation methods of electrical devices. However, mechanical equipment as mentioned above can cause frictional heat or frictional sparks during routine operation or due to equipment-upset conditions. To identify and to eliminate or to control these types of ignition sources, an analysis method that is described as a “Mechanical Equipment Ignition Risk Assessment” (MEIRA) can be used which is also called as Non-electrical Equipment Ignition Risk Assessment (NEIRA).

Mechanical & Non-Electrical Equipment Ignition Risk Assessment.mp3

For the process industry to be successful; it has become essential to identify the hazards, to assess the associated risks and to bring the risks to a tolerable level. Hazard Identification and Risk Analysis (HIRA) is a collective term that encompasses all activities involved in identifying hazards and evaluating risk at facilities, throughout their life cycle, to make certain that risks to employees, the public, or the environment are consistently controlled within the organization’s risk tolerance. Hazard identification and Risk Assessment (HIRA) is a continual process and is carried out to identify whatever could cause injury, damage & ill-health arising out of various routine & non-routine activities and processes.
