Which type of task is categorized under Class 1 according to OSHA regulations?

Class 1 tasks under OSHA regulations are classified as activities that pose a high risk of lead exposure to workers due to their intensity and the materials involved. In this context, manual demolition is categorized under Class 1 because it often involves the removal of materials that may contain lead, such as old paint, tiles, and other building components. This task typically generates a significant amount of dust and debris, which can easily contaminate the work environment with lead particles, thereby increasing the risk of lead exposure for those performing the work.

In contrast, the other activities listed may also involve lead but are classified differently due to varying levels of risk and the specific techniques employed. For instance, using lead-based mortar is a significant concern, but it may not involve the same level of acute exposure risk associated with demolition work. Power tool cleaning without dust collection, while hazardous, is usually considered a different classification based on the method used and the control measures in place. Rivet busting can also be dangerous but is typically not categorized under Class 1 due to the specific nature of the task and the associated risks being managed differently.

This classification system is crucial for ensuring that workers are adequately protected and that safety protocols are appropriately tailored to the risks associated with different types of lead-related
