Which task is classified as a Class 1 task under OSHA lead standards?

The identification of manual demolition of structures, such as drywall, as a Class 1 task under OSHA lead standards is based on the nature of the work and the potential for lead exposure. Class 1 tasks are those that involve activities where lead and lead-containing materials are removed through methods that generate substantial amounts of lead dust or particles.

Manual demolition involves physically breaking down walls or ceilings that may contain lead-based paint or other lead materials, which can lead to the release of lead dust into the air and requires careful handling and containment to ensure worker safety. This classification necessitates specific compliance measures and safety protocols to minimize lead exposure risks to workers and occupants of the surrounding area, including the use of proper personal protective equipment and work practices designed to control lead dust.

In contrast, other tasks like welding, abrasive blasting, and cutting might not inherently involve the same risk of lead dust generation when executed under certain conditions or when materials are not lead-based. Thus, while they could potentially involve lead exposure risks, they do not automatically classify as a Class 1 task in the same way that manual demolition does.
