Which of the following activities is included in Class 2 trigger task?

Class 2 trigger tasks refer specifically to activities that have a heightened risk of lead exposure due to the nature of the work being performed. Lead burning falls into this category because it involves processes that can generate lead fumes or dust, posing a significant health risk to workers.

In contrast, welding, hot work, and concrete cutting, while they may involve other hazards and risks, do not inherently trigger the same type of regulatory and safety requirements as tasks that involve the direct handling or manipulation of lead. The focus of Class 2 tasks is on those activities most directly related to lead-containing materials and the potential for lead exposure, making lead burning the appropriate choice in this context.
