If you are asking for the age of how old until you can do a hazardous job, i'm pretty sure the answer is 18 years old. You have to be 18 in order to do a hazardous job. If you are under that age, you cannot. But i have heard that you can do a job that is not hazardous at the age of 16 or 17. I hope this helped :)
