What type of receptacles are required in hazardous locations within an anesthetizing area of a health care facility?

1. Class 1, Group A

2. Class 1, Group B

3. Class 1, Group C

4. Class 2, Group A

The correct answer is: Class 1, Group C

In hazardous locations within an anesthetizing area of a health care facility, the requirement for Class 1, Group C receptacles stems from the need to ensure safety in environments where flammable anesthetics may be present. Class 1 locations are those where flammable gases or vapors can be ignited, thus necessitating specialized equipment designed to prevent ignition. Group C specifically pertains to locations that may contain flammable anesthetics such as cyclopropane or ethylene oxide. The designation as Group C indicates that the risk associated with the environment demands equipment that can operate safely without causing an ignition source. Such receptacles are designed with features that minimize the possibility of sparks or overheating, aligning with the rigorous safety standards in healthcare settings. Other groups and classes have different applications and are not suitable for anesthetizing areas due to variations in the types of flammable materials encountered or the degree of hazardous nature. For instance, Class 1, Group A or B receptacles encompass environments with different critical safety considerations, while Class 2 deals with combustible dusts rather than flammable gases, which are not pertinent to anesthetic environments. Thus, Class 1, Group C is specifically mandated for use in anesthetizing areas to maintain a safe and compliant
