Which of the following is a safety regulation enforced by OSHA related to fuel handling?

The correct choice highlights the importance of proper labeling of hazardous materials as a critical safety regulation enforced by OSHA in the context of fuel handling. Proper labeling serves several safety objectives, including ensuring that all employees are aware of the potential hazards associated with specific fuels and chemicals they are handling. Clear and accurate labels help in identifying the contents of containers and provide essential safety information, such as handling instructions and emergency protocols. This reduces the risk of accidents and enhances overall workplace safety in environments where fuel is handled.

In this realm, having materials properly labeled is vital for informing personnel about the nature of the substances they may come into contact with, which is crucial in preventing spills, leaks, and other unsafe situations. Thus, this regulation aligns with OSHA's broader mandate to ensure safe and healthful working conditions.

Other options, while related to overall safety and health in the workplace, do not focus specifically on the fuel handling aspect addressed by OSHA. The use of manual handling techniques pertains to ergonomics rather than chemical safety, employee drug testing focuses on workforce conduct rather than immediate physical safety, and lockout/tagout procedures relate to protecting workers during maintenance activities rather than specifically addressing fuel handling hazards.
