I am an industrial design student and I am working on a thesis based around construction workers clothing + fall protection. It's not limited to this topic, but I am leaning towards this direction. Definitely let me know what the most annoying things about wearing your safety harness are/ any other aspects of your job! The more complaints the better. (working in the heat/working in the cool/ safety precautions/ tools you have to always carry with you)
The survey I have covers the questions I have about your profession, but feel free to also post about it on here.
