Which type of transformer eliminates spark hazards where flammable anesthetics are used?

The transformer that effectively eliminates spark hazards in environments where flammable anesthetics are used is the isolation transformer. An isolation transformer is designed to decouple the output from the power source, providing electrical isolation. This is crucial in medical settings, especially in operating rooms where flammable gases are present.

By isolating the equipment from the power line, an isolation transformer reduces the risk of electrical shock and minimizes the chances of sparks that could ignite flammable substances. This added safety measure is vital in preventing catastrophic events during surgical procedures where anesthetic gases are in use.

In contrast, the other transformer types, while useful for various applications, do not provide the same level of protection against spark hazards associated with flammable anesthetics. They may not adequately isolate the electrical system, which is essential in ensuring safety in these critical environments.
