What can happen if temperature reaches more than 40 degrees
Staying inside a vehicle is dangerous when the internal temperature reaches 40 degrees Celsius. The interior can reach 55 ° C with a direct irradiation of the sun if the outside temperature is 35 ° C.
Temperature inside a car in summer
To make driving enjoyable and the heat does not affect our concentration and produce fatigue is important that the temperature inside the car is between 20 and 23 degrees . This temperature is achieved by the air conditioning system of the vehicle.
But what happens if the car is stopped and the engine off in the street a summer day?
Staying inside a vehicle is dangerous from an internal temperature of 40 ° C , which is reached after 42 minutes (when the outside temperature is constant 25 ° C).
In the case of an outside temperature of 35 ° C, they could reach 55 ° C in the vehicle interior after 60 minutes if the direct irradiation of the sun is.
And if those same 42 minutes past the measured temperature of the surface of the dashboard, it reaches 72,8º C! If so careful because it can damage the skin by touching a few seconds.
If inside the vehicle with a temperature of 40 degrees had children, pets or older people , they could reach dizziness and loss of consciousness.
Use the sun visor in the vehicle windshield helps reduce the inside temperature at least 11 degrees.
On the contrary, leave the windows slightly downs while the car is parked in the sun just reduce the indoor temperature by 2 degrees.
Children, the elderly and pets are most vulnerable to heat stroke
And what reaches body temperature?
– Cars with bodies painted with dark colors absorb more solar radiation than painted with light colors. For this reason the black colored vehicles get hotter in summer days.
– After both vehicles exposed to sunlight for 60 minutes, it was possible to measure a difference of almost 20 ° C between the two cars (car 80º C and 63º C Color black car white).
– The temperature increase on the surface of the vehicle occurs gradually, taking the maximum increase in the first 20 minutes of exposure.
– In the first 10 minutes of exposure to sunlight , the black car reaches a temperature of approximately 60 ° C, taking another 50 minutes to reach its maximum (80 ° C). In the case of the white car, after 10 minutes, the temperature is 50 ° C, requiring the rest of the exposure time to reach its maximum temperature of 63º C.
Briefly touch the surface of a car exposed to the sun for 10 minutes only can cause skin burns .
The black paint absorbs heat up to more than 20 ° C white paint.
Does the passenger compartment is burning?
Try to be the shortest possible time within a stationary vehicle that is exposed to direct sunlight .
The interior of the vehicle can reach 55 ° C with a direct irradiation summer if the outside temperature is 35 ° C. Continuous exposure to temperatures above 40 ° C may cause dizziness.
Children are particularly vulnerable to extremes of temperature : Due to their lower respiratory development, are more vulnerable to heat stroke. Under no circumstances let your child locked inside the vehicle: the temperature can be increased by 10 degrees in a few minutes.
Pets are also very vulnerable to extreme temperatures inside a vehicle, because unlike people do not have the mechanism of sweating to cool the body.
A parasol positioned correctly on the windshield of the vehicle can significantly reduce the temperature of the dashboard . The hood also helps that the temperature inside the vehicle is at least 11º C lower than if we did not use.
Beware of skin burns . The skin damage can occur from a temperature of 45 ° C. The internal elements of a vehicle are as the dashboard, the seats, the steering wheel or gear shift can reach temperatures close to 80 ° C if they are not protected parasol.
Leave the windows slightly open in a car parked in the sun exposure, it is not enough to keep cool inside the vehicle, it only generates a temperature difference of 2 ° C compared to leave the windows closed.
Pay attention to the color of the car before buying it. The black paint absorbs heat up to more than 20 ° C white paint .
Before starting a trip to the car well ventilated fresh air . This will help to avoid high temperatures during the trip in the event that your car does not have air conditioning.
Before using the air conditioner , it is recommended take hot air from the cooling ducts of the vehicle using the fan drive for one minute. Doing this will allow a better functioning air conditioning, while extending the life of the same.
Do not abuse the air conditioning
The temperature difference between a heated and the outside should not be a significant temperature jump vehicle. Significant differences in temperature can cause colds and malaise in the body.
