What is required for a gas appliance to have a shutoff valve?

1. It must be located outside the appliance room

2. It must be within 10 feet of the appliance

3. It must be in the same room and within 6 feet

4. None of these

The correct answer is: It must be in the same room and within 6 feet

For a gas appliance to be compliant with safety standards, having a shutoff valve is crucial for ensuring that the gas supply can be easily turned off during maintenance or in case of an emergency. The requirement for the shutoff valve to be in the same room and within a specified distance of the appliance helps ensure quick access. This is particularly important in situations where immediate action is necessary, such as in the event of a gas leak or if the appliance malfunctions. By having the shutoff valve located within the same room and within 6 feet of the gas appliance, it allows for prompt action to be taken without the need to traverse a greater distance, which could pose safety risks. This setup also ensures that the shutoff valve is not buried under equipment or otherwise obscured, promoting better safety practices in gas appliance operation and maintenance. The other options suggest locations for the shutoff valve that may not guarantee quick access, which is a critical aspect of safety regulations. Therefore, being in the same room and within the specified distance serves to enhance the safety and functionality of gas appliances.
