What motivates Oscar

After his study mathematics study, in a few years, Oscar developed himself as an all-round IT professional. In 1996, he started working as an IT coordinator at AdviSafe Risk Management. In that role, Oscar was closely involved in the development and automation of various 'safety' related processes, such as the Tripod Delta survey, the Tripod DeltaBase, Hearts & Minds and the automation of checklists for audits and inspections.

During that period, Oscar – and we quote – ‘became infected with the safety virus’. This made him to focuse primarily on projects related to risk studies (BowTie, FMECA), incident investigations (Tripod Beta, RCA, BFA, SIM, TOPSET, BSCAT, FRAM) and programs covering leadership, safety culture and behaviour (Tripod Delta, Balance and Hearts & Minds toolkit).

Starting in 2007, as a member of the Incident Investigation Flying Squad, Oscar has travelled the world and investigated numerous incidents. As a lead investigator, BowTie facilitator and accredited Tripod Beta trainer, Oscar has gained international experience in various industries, from oil & gas to medical care, and from the nuclear industry to transport via air, water, road and rail.

Over the years Oscar has become more involved in developing and conducting workshops focusing on safety leadership, at all levels in the organisation.
