Which of the following is NOT a hazardous source of energy according to safety standards?

In the context of safety standards, hazardous sources of energy are those that can cause harm or injury to people if not properly controlled or managed. Electrical, radiological, and thermal energies are all recognized as hazardous because they can lead to serious injuries or hazardous situations if proper safety protocols are not followed.

Electrical energy can result in severe shocks or burns; radiological energy poses risks from exposure to harmful radiation; and thermal energy can cause burns or heat-related injuries. Each of these sources has specific guidelines and safety measures that need to be followed to minimize risks.

On the other hand, aerodynamic energy refers to the energy associated with moving air and is typically not categorized as a hazardous source in the same way. While aerodynamic forces can be dangerous in certain contexts (like in high-velocity environments or when equipment is not properly secured), it does not inherently qualify as a hazardous energy source based on standard safety classifications. Thus, recognizing aerodynamic energy as NOT a hazardous source aligns with established safety standards.
