Summary

Firefighting is strenuous work, with high heart rates (HR) and rectal temperatures (Tre) during demanding tasks like rescue. Rotating duties can help reduce heat strain injuries in firefighters.

Area of Science:

  • Occupational Health
  • Exercise Physiology
  • Environmental Stress

Background:

  • Firefighting involves significant physical exertion and exposure to heat.
  • Understanding the physiological demands is crucial for firefighter safety and performance.

Purpose of the Study:

  • To quantify the physiological strain experienced by firefighters during various scenarios.
  • To identify the most physically demanding tasks within firefighting operations.

Main Methods:

  • Eight professional firefighters participated in six simulated firefighting scenarios.
  • Continuous monitoring of heart rate (HR), rectal temperature (Tre), and skin temperatures.
  • Data collected using a portable data acquisition system.

Main Results:

  • Average HR ranged from 122 to 151 beats/min.
  • Building search and victim rescue showed the highest HR (153 beats/min) and Tre increase (1.3°C).
  • Crew captain duties had the lowest HR (122 beats/min) and Tre increase (0.3°C).

Conclusions:

  • Firefighting, particularly interior tasks, is highly strenuous.
  • Physiological demands vary significantly based on specific duties performed.
  • Frequent duty rotation with less strenuous tasks may mitigate heat strain injuries.
