In today’s world, where the automotive industry faces many challenges, preventing fires caused by technical faults or design flaws has become one of the main priorities. The goals of safety and fire audits include not only improving production quality but also ensuring compliance with legal requirements and international standards. In this regard, reducing costs resulting from recalls and warranty claims, as well as increasing the trust and satisfaction of end customers, are also among the key objectives of this process.

From Design to Field Inspection

The Vehicle Quality Inspection Department of the Iran Standard & Quality Inspection Company reports on the vehicle safety and fire audit process. According to this unit, conducting a vehicle safety and fire audit includes four specialized phases, explained as follows:

Phase 1 – Document and Product Design Review

In this phase, the design documentation of electrical and fuel supply systems is analyzed, wiring diagrams and fuel/liquid routing are examined, and finally, the thermal management and ventilation systems are evaluated.

Phase 2 – Field Inspection in the Production Line

Here, inspections are carried out directly on the production line. First, safety-critical and high-risk component stations on assembly lines are identified. Then, the quality of electrical and mechanical connections is examined. Checking insulation and cable resistance against temperature is also among the most important tasks in this phase.

Phase 3 – Performance Testing

This phase involves practical testing. Indicators such as leakage or spraying of corrosive liquids or dirt, part collisions, gaps and looseness, missing or mismatched components, weak connections, or improper installations are thoroughly inspected under realistic conditions. Furthermore, compliance with quality requirements in part installation—such as pipe markers, component labeling, and proper fastening—are checked, along with identifying issues like over-tightening, stretching, or excessive length in wires, hoses, and similar components. In addition, testing the heat resistance of critical parts, performing fire tests based on real scenarios, and evaluating the performance of safety systems under emergency conditions are also carried out at this stage.

Phase 4 – Analysis and Recommendations

Finally, results are analyzed, and corrective and preventive solutions are proposed. This includes identifying critical weaknesses, offering improvement suggestions, and preparing technical and managerial reports with prioritized actions.

Final Outputs: Ensuring Safety and Quality

At the end of this process, comprehensive technical reports—including findings, risk analyses, and corrective actions—are produced. Audit checklists for follow-up improvements and a compliance certificate (if conditions are met) are also issued by the inspection company. Additionally, technical support continues until all weaknesses are fully resolved.

Without a doubt, vehicle safety and fire audits are not only a way to prevent catastrophic fires but also an important step toward improving production quality and enhancing customer satisfaction.
