EXPERIMENTAL STUDIES OF ENERGY CONSUMPTION AND THERMAL STATE OF THE BODY OF FIREFIGHTERS IN PROTECTIVE CLOTHING

Abstract

In Ukraine, extreme microclimatic conditions (elevated temperature, high and low
humidity, air velocity, gassiness, smoke) occur at production or during emergency rescue
operations by units of the State Emergency Service of the Ministry of Internal Affairs of
Ukraine and the State Militarized Mining and Rescue Service.
The performance of emergency and rescue work at fires and liquidation of accidents
requires the personnel of the Operational and Rescue Service of the Emergency Situations of
Emergency Situations to respond quickly to emergency situations, make effective technical
decisions, high professionalism and is associated with high physical and psychoemotional
stress on the body of the firefighter-rescuer.
The training of firefighters and rescuers to carry out rescue operations in conditions
of ergothermic loads is a professional necessity in the conditions of a real fire and liquidation
of the consequences of missile and bomb attacks as a result of the aggression of the occupiers
on the infrastructure of Ukraine.
The works of fire safety specialists, in which the influence of various types of
performed operations and the conditions of their execution, are devoted to the study of the
energy consumption of the body of firefighters and mine rescuers.
The article examines the results of experimental studies of energy consumption and the
thermal state of the body of firefighters in protective clothing.
The main components of the heat balance, on which the duration of a person's work
depends, are the internal energy produced by his body - the heat production of the
firefighter's body, which in turn depends on the amount of energy consumption, and external
energy that penetrates from the outside. At the same time, external energy is, as a rule, a
factor independent of a person, and internal energy depends on many parameters.
