G2 Gas Fitter Practice Exam

For a unit heater installed at a distance of 10 feet or more from the floor, the requirement for service access emphasizes safety and efficiency during maintenance. A permanent service platform surrounding all parts of the unit heater or an approved man-lift provides the necessary stability and support for technicians to access the unit heater safely. A permanent service platform allows for ample space for both personnel and tools, reducing the risk of accidents and ensuring that any maintenance or service tasks can be completed effectively. Man-lifts, when approved, also provide a safe means to reach elevated equipment while offering a secure working space. Other options, such as an access ladder, standard walkable platforms, or mobile scaffolds, may not provide the necessary level of safety and accessibility required for such high installations. Therefore, the emphasis on a permanent service platform or an approved man-lift is crucial for compliance with safety standards and for effective maintenance of unit heaters positioned at a significant height.
