ISA-12 pertains to what kind of equipment?

ISA-12 specifically addresses electrical equipment designed for use in hazardous locations. The standard establishes guidelines and requirements that ensure these devices operate safely in environments where flammable gases, vapors, or dust might be present. This is critical to preventing potential accidents and ensuring the safety of personnel and assets in industrial settings.

The emphasis on hazardous locations is crucial because such environments pose significant risks that require specialized equipment to minimize the chances of ignition and explosion. Therefore, adhering to ISA-12 standards ensures that the electrical equipment is suitably designed, constructed, and tested to handle specific hazards safely.

Other options mention software, general-purpose devices, and telecommunication systems, which do not align with the specific focus of ISA-12 on ensuring safety and functionality in potentially dangerous environments through specialized electrical equipment. This highlights the uniqueness of ISA-12 within the context of industrial safety standards.
