Which of the following is NOT a type of energy considered in lockout/tagout?

The correct choice, indicating that magnetic energy is not a type considered in lockout/tagout, highlights an important aspect of energy types relevant to workplace safety. In LOTO practices, the primary focus is on hazardous energy sources that can pose risks during maintenance or servicing of equipment. Each energy type listed plays a role in potential workplace hazards.

Gravity represents a significant hazard as it can lead to falling objects or the uncontrolled descent of machinery. Electrical energy is critical in LOTO protocols since it can cause serious injuries or fatalities if equipment is accidentally energized while being serviced. Chemical energy is also a concern, as it can lead to exposure or reactions if systems containing hazardous chemicals are not properly managed during maintenance.

Magnetic energy, while it may be a factor in some specialized industrial safety contexts, is generally not categorized under the common types of hazardous energy addressed in standard lockout/tagout procedures. Consequently, it is appropriate to exclude it from the types of energy explicitly covered in LOTO training and practices, focusing instead on those that directly pose a risk during maintenance tasks.
