KEY ISSUES • Roles and responsibilities unclear • Contractor Management • Safety-critical procedures • Work preparation and planning • HSE focus and awareness • Lack of intervention by staff

KEY ISSUES • Incomplete corrosion management • Inadequate appreciation of risk • Failure to follow procedures • Inadequate knowledge of the narcotic effects of condensate

4 fatalities and 1 injured person when working in a cofferdam

3 fatalities – 7 injuries during welding and grinding work above a tank that contained flammable materials

KEY ISSUES • Understanding of the potential hazards of hydrocarbons • Contractor Management • Applying the hierarchy of controls • Managing confined space risks excavations

KEY ISSUES • Roles and responsibilities unclear • Inherently Safer Design • Process Hazard Analysis • Ineffective Safeguards • Hot Work Safety Management

Info for Supervisors & Managers • This SPOT THE HAZARD Incident flyer is meant for people working on sites. • Mostly there are multiple issues that result in an incident, many of them start in the office • Barriers were broken, or missing and critical processes were not in place • As a Supervisor or Manager you are responsible to make sure that critical processes are working well • People involved in design or the preparation of work are responsible for hardware barriers • People working on site are responsible for the human barriers and as a supervisor you influence their behavior! • Use this SPOT THE HAZARD Incident flyer to explain the key issues relevant to people working on site • Ask open questions to check, and double check, that everybody understands their role in avoiding incidents (For people working in the office separate follow up is recommended)

Recommended follow-up Reflective Learning: Removing the Hazard Reflective Learning: I Own My Barrier More info on the Hearts & Minds website Info on the US incident can be found on the CBS website
