Fire and electrical safety. The first thing that we need to warn you about is fire and electrical safety. It's very important that extra precaution is taken to make sure that any heating and lighting devices are properly wired and placed in a safe part of the habitat. Heat lamps, ceramic heating elements and basking bulbs need to be placed in the habitat far enough away from flammable materials so that they do not catch fire. Every so often, there is yet another story of someone's house catching on fire because of an iguana habitat that was not set up properly.
Most larger habitats are custom built by the iguana owner, and many times they are improperly wired.
It's imperative that you use any electrical device as directed by the manufacturer. Extension cords are another common cause of electrical fires because a cord that was overloaded with too many lights and heating devices. It can be a pretty common site to see a habitat that has far too many things plugged into one electrical outlet and several small extension cords throughout the entire setup. Using quality power strips and heavy duty extension cords should be the only choice, other than directly wiring the habitat into your house's electrical system. Another very important thing to remember is that all the electrical devices in the habitat should be grounded.
