Electrical Wires

Electric wires poking through the paneling in the ceiling, is it safe to use? 

The general rule of thumb is to never have any wires just hanging around, either in the ceiling or the walls. All wires should be stapled to the wall studs (or equivelant) as well as secured into a j-box (junction box) with fixed entry points. Also, they should be properly wire nutted inside the j-box and a cover should be in place. The j-box MUST be easily accessable and therefore must be in visable sight, just like a wall switch or duplex (socket).  I would discuss this with a person in the electrical department of a home improvement store, or call your local building department and get some advice. A lot of fires start from faulty wires and installations made by people who just don’t know the proper way to do the job. Safety first…..I hope this helps
