The correct choice is formaldehyde levels, as OSHA (Occupational Safety and Health Administration) sets and enforces standards regarding workplace safety and health, which include permissible exposure limits for hazardous substances. Formaldehyde is recognized as a potential health hazard due to its carcinogenic properties and the risks associated with short-term and long-term exposure. OSHA provides regulations that dictate acceptable exposure limits, monitoring requirements, and necessary protective measures to ensure the safety of workers who may be exposed to this chemical.

The other options, while they relate to safety and standards, fall outside the scope of OSHA's regulations. Building size is typically addressed by local building codes rather than federal regulations. Handicap access is governed primarily by the Americans with Disabilities Act (ADA), which outlines requirements for accessibility in public and commercial spaces, rather than by OSHA. Backflow preventers are related to plumbing and public health standards and are regulated by local health departments or plumbing codes, not by OSHA. Therefore, formaldehyde levels are directly regulated by OSHA to ensure workplace safety concerning hazardous chemical exposure.
