EEHA Expert System¶
Overview¶
The EEHA (Electrical Equipment in Hazardous Area) Expert System is configured to assist in the management of electrical equipment in hazardous areas. The large volume of Ex equipment that typically exist on many sites can often lead to difficulties in performing inspections and managing the data associated with them. The EEHA expert system can assist by providing a mobile electronic inspection solution that will instantly feed to the database. From here, the data may be used to demonstrate KPIs, perform RBI assessments and plan/create of work pack. Allowing the user to reduce the inspection load and manage the data effectively to meet the required regulations.
