Which of the following groups includes forms of dangerous energy?

The correct choice accurately identifies specific forms of dangerous energy that can pose significant hazards in various work environments. Steam, hydraulic power, spring tension, and compressed gases are all forms of energy that, if not managed properly, can lead to serious injuries or accidents.

Steam can cause burns or scalding, hydraulic systems can lead to uncontrolled movement of machinery, spring tension can result in sudden release and projectile hazards, and compressed gases can explode, leading to both pressure injuries and hazardous spills. Understanding these forms of energy is crucial in implementing effective safety measures to mitigate risks associated with their use in operations.

Other groups listed either represent forms of energy that are less directly associated with severe immediate hazards or pertain to environmental factors rather than the more concrete types of dangerous energy present in machinery and systems.
