Which two aspects are not specified requirements of the ANSI standard?

The correct answer highlights that the ANSI standard does not specify requirements for lighting and ventilation. The ANSI (American National Standards Institute) standard is primarily focused on various building and construction needs, but it does not dive into specifics about every possible element, such as lighting and ventilation, which might be under the purview of other codes or standards.

Lighting is often dictated by different regulations depending on the type of building and its intended use. Similarly, ventilation requirements can be informed by local building codes that prioritize functionality, air quality, and energy efficiency, rather than directly referencing ANSI.

Therefore, the choice pointing out lighting and ventilation correctly identifies areas that ANSI does not make explicit requirements for, while other aspects like storage or heating are often addressed more explicitly within various standards or codes. Understanding this distinction is crucial for comprehending how different regulations and standards interact within the broader framework of building practices.
