Shutoff valves must be readily accessible primarily for emergencies and maintenance purposes. In the event of a gas leak or other urgent situations, having quick access to the valve allows for immediate action to stop the flow of gas, thereby minimizing potential hazards and ensuring safety. Regular maintenance and inspections are also vital for ensuring the proper functioning of gas systems, and easily accessible shutoff valves facilitate these activities.

The other options suggest conditions where access might not be prioritized, such as placing valves out of sight or only requiring access in certain types of buildings. However, safety regulations typically mandate that shutoff valves must be located in a way that they can be quickly reached in any scenario, emphasizing the universal need for accessibility, regardless of building type or traffic flow.
