Heat stroke is the physiological hazard which occures when the management of the heat stress is improper. Besides environmental factors (temperature, humidity,radiant heat), heat stress is determined by the regimen of work and clothing requirements of the persons. It is important to have a routine in order to manage heat stress in every workplace. Such a possible routine it's described in the next three steps to be followed:
1) Evaluation of the heat stress which is done using a screening method established by the ACGIH (American Conference for Governmental Industrial Hygenists).
2) Screening and limitation of heat stress for the persons exposed to it. Pursuit of body temperature variations by using a thermometer.
3)Use of strategies of managing heat stress
The following signs are the mark of an occuring heat stress and they are requesting medical emergency care:
-confusion, irritability,disorientation, the loss of weight per shift is greater than the 1.5% from his body weight, the amount of sodium from his urinary, during a day, is less than the quantity of 50 milli-moles.
To avoid all these physiological hazards, the following measures could be applied:
-the time spent and worked in overheated environment should be shortened and followed by a time for resting in cool places;
-the amount of water intakes should be increased;
-the workload should be distributed;
-disseminating the informations about the symptoms of heat stress so that the workers to protect themselves;
-scheduling the jobs which require hot conditions during the cooler part of the day or maybe choosing a cooler season for performing these activities.
