It's thought that Harry S. Truman is the one who coined the phrase, and he used it as early
as 1942. A newspaper from that year, called The Soda Springs Sun, quoted him:
"Favorite rejoinder of Senator Harry S. Truman, when a member of his war contracts

of the kitchen."
So, the idea here with this expression is something like this: With ovens turned on and pans heating up on the stove, the temperature in the kitchen can rise, becoming a hot place to work in. Some people might be uncomfortable working or just being in such a heated environment. Thus, if that's the case, it would probably be best for them to get out of the kitchen and leave the work to someone else.
