Risk Matrix #132: Simultaneous Operations (SimOps) Is Not Just a Safety Checkbox

Organizations managing complex contractor operations face a critical coordination challenge: ensuring multiple work scopes don’t create invisible hazards that contribute to serious incidents.

In this episode Dr. Martin and James examine findings from the Chemical Safety Board’s investigation into the fatal H2S release at Pemex Deer Park Refinery and discuss how permit-to-work systems can fail when simultaneous operations become routine checkboxes rather than active coordination processes. They break down common gaps in contractor safety coordination, including permits that attempt to authorize too many activities under one document, high-consequence work that gets buried in routine documentation, and communication breakdowns between multiple work crews operating in adjacent areas.

KEY TAKEAWAYS

• Overly broad permits create an illusion of sameness that obscures high-hazard work. According to the CSB report, when permits list multiple energy isolation points under one authorization without distinguishing high-consequence activities, critical safety information may not reach workers who need it. Organizations should separate high-consequence work into distinct permits with specific hazard briefings.
• Individual procedural drift compounds across multiple contractors working simultaneously. When several work crews operate in adjacent areas, small deviations from standard procedures can create unanticipated interactions. Effective simultaneous operations management requires communication protocols that account for how activities in one work area may affect crews in adjacent spaces.
• Permit systems should reflect actual work conditions, not idealized procedures. Safety audits and permit reviews should verify whether documented procedures align with field practices. When job hazard analyses don’t match how work is actually performed, organizations should pause operations to reassess hazards and update communication protocols.
