Plumbing Safety

I am studying a trade course and have a Kaplan task about safety when working with plumbing equipment. I need to discuss risks from tools, water, electricity, and poor work areas. I searched for Pay someone to do Kaplan assignment when I got stuck, but I want to learn the topic and complete it myself. Would it be better to explain each risk separately or use one workplace example? What safety points should a beginner make sure not to forget? Any practical suggestions would be really useful.
