What signifies a "high hazard" construction activity?

A "high hazard" construction activity is characterized by tasks that present an increased risk of serious injury or death. This designation typically applies to activities that involve significant danger due to their nature, complexity, or the environment in which they are performed. For instance, demolition work can expose workers to numerous hazards, such as falling debris, unstable structures, and the potential for unexpected structural collapses. The identification of high hazard activities is crucial for implementing appropriate safety measures, training, and personal protective equipment to minimize risks.

While other options may involve some level of hazard, they do not inherently signify "high hazard" status. For example, crew leaders may oversee activities but their role is managerial rather than inherently dangerous. Quick completion of tasks doesn't directly equate to higher risk; some activities may be quick but still relatively safe. Lastly, activities involving heavy machinery can be hazardous, yet not all such operations are classified as high hazard unless they meet specific criteria, such as the likelihood of severe accidents or the presence of additional risk factors. Thus, the correct identification of high hazard activities helps ensure that adequate precautions are taken in a construction environment.
