Which of the following tasks is classified as a Class 3 task?

A Class 3 task in lead abatement is defined as a task that may not involve the highest risk of lead exposure but still requires specific controls and precautions. Torch burning of lead-based paint falls under this classification because it involves generating high heat, which can release lead particles into the air, necessitating proper containment measures and safety protocols to mitigate lead exposure.

Manual scraping or sanding, as well as power tool cleaning using dust collection systems, are typically classified as Class 1 or Class 2 tasks due to the direct engagement with lead surfaces and the potential for creating significant lead dust or particles without appropriate controls.

Spray painting with lead-based paint is considered particularly hazardous due to the potential for aerosolized lead, but it also doesn't qualify as a Class 3 task. Instead, it would be grouped with the higher-risk categories requiring more stringent controls.

Understanding these classifications is essential for ensuring that appropriate safety measures are taken during lead abatement activities, protecting both the workers involved and the environment.
