Why are isolated systems predominantly used in healthcare facilities?

1. For increased productivity

2. To save on installation costs

3. Due to explosive gases

4. To enhance electrical performance

The correct answer is: Due to explosive gases

Isolated systems are predominantly used in healthcare facilities primarily to ensure patient safety and maintain a safe environment where medical procedures take place. In these settings, the presence of explosive gases or volatile anesthetic agents can pose significant risks. An isolated power system, which prevents ground faults and minimizes electrical noise, is crucial in such environments to protect both patients and medical staff from electrical hazards. The choice related to explosive gases reflects the need for a controlled and stable electrical environment, thereby reducing the likelihood of ignition from electrical faults. Utilizing an isolated system helps to contain any potential electrical malfunctions without putting the sensitive equipment or patient safety at risk. In contrast, while increased productivity and enhanced electrical performance may be benefits of well-designed systems, they are not the primary reasons isolated systems are a requirement in healthcare. Installation costs can vary based on many factors, but cost-saving measures typically do not prioritize safety in healthcare environments where patient care is paramount.
