Which of the following is a primary function of the GPSC in relation to safety?

The Georgia Public Service Commission (GPSC) plays a crucial role in overseeing the safety of natural-gas pipelines specifically, which is essential given the potential risks associated with natural gas transportation. The GPSC is tasked with ensuring that these pipelines meet safety standards to prevent accidents and protect the public from hazards. This involves the regulation of operations, maintenance practices, and compliance with federal and state safety regulations, ensuring that the infrastructure is secure and reliable.

The other options, while they touch on safety aspects, do not specifically align with the primary responsibilities of the GPSC. Setting safety regulations for all industries is outside the scope of the GPSC's duties, which are more focused on utilities. Conducting safety inspections for all public utilities is a broader task that encompasses various utilities but does not specifically highlight the GPSC’s unique role in natural-gas pipeline safety. Regulating pollution output is also something handled by other agencies, such as environmental regulators, rather than the GPSC, which is more concerned with service quality and safety in the utilities sector, particularly gas pipelines.
