Today (13th) was a steamy day, and workers who work outside in the heat can be threatened with health as well as life. The government has put in place some sort of protection, but workers say more practical measures are needed.

It is a construction site where the sun shines.

When the temperature soared to 34 degrees, workers flock in the shade.

They try hard to cool down and spray cold water.

[Construction Worker: When the cement gets heat, it actually comes back to 56 degrees when it comes to the thermometer. Sometimes exhaustion comes.]

The government has mandated a place to rest, provide time and provide drinking water since last year to prevent heat illness from construction workers.

But the workers say that they are not kept properly.

Less than three out of 10 respondents say they can relax in the shade, and 15 percent say they don't get cool water on time.

You should stop working especially when you have a heat wave above 35 degrees.

78% of respondents say they continue to work.

[Jeong Byeong-cheol / Construction Workers: I have repeatedly seen two or three people falling down at my work site and losing their lives once a year. I don't want to die anymore.]

Last year, five workers were recognized for their deaths due to the death of a thermal illness, but they may increase as the warming increases.

The labor union said that it is mandatory to stop work during the heat wave, and to protect workers.
