Final answer:
CNG and LPG flammable gas containers should be located away from residential areas to minimize risks to public safety.
Step-by-step explanation:
CNG (Compressed Natural Gas) and LPG (Liquefied Petroleum Gas) containers, which store highly flammable gases, should be located away from residential areas to ensure safety. Both CNG and LPG are flammable and pose significant risks if they leak or are exposed to an ignition source. Residential areas are places where people live and gather, and in the event of a gas leak or explosion, the consequences could be catastrophic due to the higher population density and the presence of homes, schools, and healthcare facilities. Therefore, for safety reasons, it is essential that CNG and LPG storage facilities are situated at a safe distance from residential zones to minimize potential harm to the public.
