That is almost as hot as the hottest days in the Sahara Desert! You can't just walk in.
You need to prepare carefully and wear special clothes.
First, you have to put on a vest,which has more than 12 ice packs across the front and back.
After this comes another vest. This keeps the heat away from the ice.Over this,you have to wear a bright orange caving suit. You also need a mask that blows ice-cooled air.
