Many contractors build in several states and many also build in different countries. And if you are not interested in travel, construction can still be your field. Talk to your parents, teachers and guidance counselors. Register in your school's construction program, and work hard to do well. Ask your school to contact a construction association in your area.
Contractors pay dues to belong to the association.
The association represents the contractors on matters that are important to them. The association can put your school in touch with contractors who are interested in working with you and your school. You are as safe as you want to be. It's just like everything you do in life. But if you ignore the rules and don't use the equipment, you won't be safe.
