What is required of propane cylinder shutoff valves according to NFPA 1192 regulations?

According to NFPA 1192 regulations, propane cylinder shutoff valves are indeed required to have protective features. These features are essential because they enhance the overall safety of the propane system by preventing accidental release of gas. Protective features can include items such as safety collars or guards that help shield the valve from physical damage and reduce the risk of leaks.

Such protections are critical in minimizing hazards associated with propane, such as fire or explosion risks. Ensuring that valves are designed with these safety features aligns with the regulatory emphasis on safe handling and storage of propane to protect both users and the environment.

The other options, while related to safety and maintenance, do not reflect the specific requirements set forth in NFPA 1192 regarding shutoff valves. For instance, while automatic closing and removable valves can enhance safety and maintenance, the primary regulation focuses on the necessity of protective features for the shutoff valves themselves.
