Consultants or educators available to assist instructors in reviewing safety regulations typically come from which source?

The correct answer highlights that regulatory agencies are key resources for instructors seeking to review safety regulations. These agencies are responsible for creating and enforcing the safety standards and regulations that govern fire safety and training practices. They employ experts in the field who can provide authoritative insights and updates on the latest regulations. Instructors benefit from the guidance of these professionals, ensuring that their teaching is aligned with current safety requirements and practices.

In contrast, community colleges may offer courses that include safety training but do not specialize specifically in regulatory oversight. Private training firms provide education and training, yet may not have direct authority or extensive knowledge about the development and adherence to safety regulations. Online education platforms can be useful for accessing information, but they do not typically provide the same depth of engagement with regulatory processes that regulatory agencies can offer. Thus, regulatory agencies stand out as the most reliable source for this specific need.
