DESIGN & EVALUATION OF SAFETY INSTRUMENTED SYSTEMS

DESCRIPTION

The best safety systems is not the most expensive but rather it is the mostpracticable system; this workshop focuses on the HAZOP management, Safety StandardControl, Hazardous Area & Electrical Classification planning and execution ofautomatic safety systems.
