The report shows that, when the internal temperatures of thefactory exceed 29°C, production decreases by 18% and loss of accuracy increases to 40%. Productivity losses due to high temperatures can be documented by their own production records.

Protecting workers in warm environments
Many workers spend part of their working hours in a warm environment. How could they be:
foundries, laundry, construction projects and bakeries, to name a few industries,
They are often faced with hot conditions that pose particular risks to safety and health.
Heat stress causes reactions in our body
Four environmental factors affect the amount of stress a worker faces with high temperature work: temperature, lhumidity, radiant heat (such as the sun or an oven) and lair. Perhaps the most important thing for the level of stress a worker faces are characteristics such asage, weight,physical state,state of health andheat acclimation.
The body reacts to the high external temperature by circulating blood to the skin. This causes an increase in the temperature of the skin and allows the body to release its excessive heat through it. However, if muscles are used for physical work, less blood is available for
which flows into the skin and releases heat.
Sweat is another way the body uses to maintain a stable internal body. sweat nis effective only if the level dhumidity is low enough to allowevaporation and if liquids and lost salts are correctly
replaced.
Of course, there are many steps thatA person can choose to reduce the risk of heat, such as moving to a cooler place, slowing down work or loading, or loosening certain clothes.
But if the body can’t get rid of theExcess heat, it will store it. When this happens, the body’s central temperature and heart rate increase. As the body continues to store heat, theIndividual begins to lose concentration and has difficulty working, it can become irritable and often the desire to drink is lost. lnext step consists of sFaint and die if the person does not withdraw from the heat.
How to prevent heat stress?
Most heat-related health problems can be avoided or reduced at the risk of developing them. Compliance with certain basic precautions should reduce heat stress.
1. Evaporative and mechanical cooling, refrigeration is theOne of the ways to reduce heat. Cooling fans can also reduce heat under certain conditions. lSteam Leak Removal will also help. The changes in theequipment, lUse ofPower tools to reduce manual labor and personal cooling devices or protective clothing are dother ways to reduce the risk ofExposure to heat for workers.
2. provide manypotable water In the workplace, it can help reduce the risk of thermal disturbances. Training of first aiders to recognize and treat heat stress disorders. Employers must also take into account the physical condition ofa worker to determine their physical condition whenThey work in hot environments.
3. Other periods of work and rest With longer rest periods in a cool area can help. If possible, heavy work should be scheduled during cold periods. Supervisors should be trained to detect early signs of heat stress and allow workers to disrupt their workHe is extremely uncomfortable.
4. Heat acclimation By short exposures followed by longer periods of work in a warm environment can reduce heat stress. Workers returning froman absence of two weeks or more must have a period of5-day acclimatization. This period should begin with 50% of the normal workload and time dExposure on the first day and gradually increase to 100% on the fifth day.
5. lWorkers’ education It is essential for them toBe aware of the need to replenish liquids and lose salt through sweat and recognize dehydration,exhaustion, fainting, cramps, salt deficiency, lthermal exhaustion and heatstroke. Workers must also be informed of theImportance of daily weighing before and after work to avoid dehydration.
Thermal disturbances
heatstroke, is the most serious health problem for workers in hot environments, its cause is caused by failure of the internal mechanism of the body to regulate its central temperature. Sweating Sstops and the body can no longer get rid of theExcess heat. The symptoms are: mental confusion, delirium, loss of consciousness, convulsions or coma; a body temperature of 41ºC or more And dry, warm skin that can turn red. the victims ofheatstroke will die unlessthey are not processed in a short time. Waiting formedical help, the victim must be transferred to a cool area and his clothes wet withfresh water, they must be vigorously ventilated to increase cooling. lhelp can prevent permanent brain injuries andother vital organs.
exhaustion by heat This is due to the loss of fluid by sweat, because the worker ndidn’t drink enough liquids or nnot ingested enough salt. The worker suffering fromHeat exhaustion is still sweating but experiences extreme weakness or fatigue, dizziness, nausea or headaches. The skin is sticky and moist, the complexion is pale or red. The treatment is generally simple: the victim must rest in a cool place and drinkwater or an electrolytic solution (drink used by athletes to quickly restore salts of potassium, calcium and magnesium). In severe cases, victims who vomit or lose consciousness may require longer treatment under medical supervision.
heat cramps, painful muscle spasms, occur when workers drink large amounts ofwater but fail to reconstitute the loss of salt from their bodies. The muscles used to perform the work are generally the most sensitive to cramps. Cramps occur during or after working hours and can be relieved by taking oral fluids or intravenous saline solutions for faster relief, if necessary medically.
lfainting (heat syncope) This occurs when theenvironment nis not ventilated and the heat remains stagnant. Victims usually recover quickly after a short period ofFainting. Moving, instead of standing still, will generally reduce the chances of sFaint.
lrash, also known as thorny heat, can occur in hot and humid environments where sweat nis not easily removed from the skin surface by evaporation. causing a significant infection, the heat can be so uncomfortable thatIt inhibits the performance of workers or even produces total temporary disability. It can be avoided by resting in a cool place and letting the skin dry.
