Before you buy, rent, or lease an apartment or office, be sure to request an inspection of the internal natural gas network. Do not move into the residence until you are sure that your safety is protected. Often, apartment owners install cheap and dangerous open-chamber gas appliances in rental spaces for the sake of the economy, which is very dangerous. Unfortunately, 70% of CO poisoning or deaths occur in rented and mortgaged apartments. Do not endanger your life or the lives of others. Call 114.
