Electrical Hazardous Operability review
eHAZOP is the application of a series of technical examinations and audits to assess hazard potential to personnel and plan of mistaken operation of a system or malfunction of individual components and consequential effects including operator error.
Objectives of a eHAZOP Study are summarised as to
Assess and minimise types of potential hazard presented to personnel in the vicinity of electrical installations.
Provide a critical review of both network design and plant to be installed and assess any limitations and their effects on both operability and security of the overall system.
Analyse tasks set for operators assess facilities and instructions provided to undertake these tasks and recommend measures to avoid operator error.
eHAZOP is made up of three modules
SAFAN – Safety Analysis
– Critical analysis of high voltage installation hazards to safeguard equipment and personnel.
SYSOP – System security and operability
– Systematic review of engineering design to identify possible limitations and lack of flexibility with their consequences to operability and overall security of the system.
OPTAN – Operator task analysis
– Identifying facilities and skill levels required to carry out the operation in a safe manner during normal and abnormal conditions.
