Accident & Incident
Investigation

Independent investigation of fire and explosion events covering scene examination, evidence review, potential ignition sources, fire propagation, equipment and operational conditions, emergency response, barrier failures and corrective actions.

What We Do

• Scene and evidence assessment
• Ignition-source evaluation
• Fire propagation
• Operational conditions
• Emergency response
• Barrier analysis
• Root cause analysis
• CAPA

Specialist investigation of process and operational incidents involving process operations, loading/unloading, transfer systems, process equipment and process-safety barriers.

What We May Examine

• P&IDs
• Operating philosophy
• ESD systems
• Interlocks and permissives
• Alarms
• SCADA/PLC data
• MOC
• PTW
• SOPs
• Maintenance
• Process barriers

Investigation of lifting incidents covering equipment condition, lifting plans, rigging, inspection and certification, operator competence, supervision, ground and environmental conditions, execution and operational controls.

What We Do

• Equipment condition
• Lifting plans
• Rigging
• Inspection and certification
• Operator competence
• Supervision
• Ground and environmental conditions
• Execution

Independent investigation of injuries, lost-time incidents, near misses, contractor incidents, unsafe conditions and serious HSE events to identify immediate, underlying and systemic causes.

What We Do

• Injuries
• Lost-time incidents (LTIs)
• Near misses
• Contractor incidents
• Unsafe conditions
• Serious HSE events

Investigation of spills, releases, contamination and other environmental events, including containment, emergency response, compliance obligations and preventive controls.

What We Do

• Spills
• Releases
• Contamination
• Environmental-control failures
• Emergency response
• Legal compliance
• Environmental CAPA

Investigation of vehicle, tanker, fleet, loading, unloading, warehouse and logistics incidents involving people, equipment, procedures, route conditions and operational controls.

What We Do

• Vehicle and tanker incidents
• Loading and unloading
• Warehouse operations
• Fleet
• Operator factors
• Route conditions
• Equipment
• Logistics controls

Independent assessment of information-security incidents focusing on governance and control failures, available evidence, response effectiveness, organizational impact, lessons learned and corrective actions.

What We Do

• Governance and control failures
• Available evidence
• Response effectiveness
• Organizational impact
• Lessons learned
• Corrective actions

Investigation of significant disruptions and recovery failures to determine why continuity or recovery arrangements succeeded or failed, and to identify weaknesses in preparedness, response, continuity arrangements and recovery capability.

What We Do

• Preparedness
• Response
• Continuity arrangements
• Recovery capability
• Resilience improvements

Technical investigation of equipment failures considering equipment condition, inspections, maintenance history, calibration, defects, modifications, temporary repairs, operating conditions and other contributing factors.

What We Do

• Equipment condition
• Inspection
• Maintenance history
• Calibration
• Defects
• Modifications and temporary repairs
• Operating conditions

Depending on the incident, ISDT applies structured techniques to distinguish immediate causes, contributing factors, underlying causes and root/systemic causes, and develops prioritized corrective and preventive actions.
