Which statement best defines a mishap?

• A. A minor incident with no consequences.
• B. An injury only.
• C. An unplanned event or series of events resulting in death, injury, occupational illness; damage to or loss of equipment or property; or damage to the environment.
• D. A routine maintenance action.

Answer: (C)

A mishap is an unplanned event or sequence of events that results in harm or loss. It covers not just injuries or deaths, but also occupational illness and damage to or loss of equipment, property, or the environment. The key is the unplanned nature and the range of possible consequences.

That’s why this option is the best: it fully captures the unplanned aspect plus the potential outcomes across people, equipment, and the environment. The other descriptions miss important parts: one describes only a minor incident with no consequences, which isn’t a mishap; another limits it to injury only, ignoring property or environmental damage; and a routine maintenance action is planned and not a mishap.
