◦ Acted as Process Safety Engineer and ensured Plants Process Safety Management (PSM ) Standards are
adhered and plants safety policies are implemented and during operations and reduced PSM related
incidences to As Low as Reasonably Practicable (ALARP).
◦ Coordinated Pre start-up safety reviews (PSSR) and resolved PSM related issues before commissioning of
TEAL, Zeigler Catalyst, unloading arm.
◦ Ensured that non conformities (NC) are reduced during PSM audits.
