What is the maximum length for a portable appliance gas hose?

1. 20 feet

2. 30 feet

3. 40 feet

4. 50 feet

The correct answer is: 30 feet

The maximum length for a portable appliance gas hose is set to ensure safety and efficiency in the use and operation of gas appliances. A gas hose that extends too far can lead to potential hazards such as excessive pressure drops, difficulty in handling, and increased risk of damage or leaks. The regulation specifies a maximum length of 30 feet for portable appliance gas hoses, as this length adequately accommodates varying kitchen or appliance configurations while maintaining safety standards. Using a hose that exceeds the specified maximum length can compromise the functionality of the gas appliance and introduce risks that could lead to unsafe operating conditions. Therefore, the choice of 30 feet adheres to established safety regulations and best practices in the gas fitting industry.
