Research on the response of rescuers during interventions in high temperature and humidity environments within the Petrobrazi refinery

Intervention and rescue missions conducted in environments with elevated temperature and humidity levels can only be performed by personnel who are appropriately trained and certified, and who utilize individual respiratory protective equipment. A critical factor in the success of such operations—particularly in toxic, explosive, or flammable settings—is the continuous improvement and optimization of training protocols for intervention and rescue teams. This includes conducting performance evaluations under simulated conditions that replicate high thermal and humidity stress. The present study explores scientific research on the physiological responses and parameter variations observed in intervention and rescue personnel operating in thermally and environmentally challenging conditions. In recent decades, the accelerated pace of industrial and economic development has brought increased attention to occupational and industrial hazards, as well as to the growing complexity and diversity of associated risks. Operations carried out in hazardous environments—especially in scenarios involving accidents or system failures that may compromise the safety of personnel or assets, and where concentrations of toxic or asphyxiating substances exceed regulatory thresholds—necessitate the use of specialized respiratory protective equipment to ensure personnel safety and operational efficiency.
