What level of dust should be present in a well-maintained workspace according to Veleda's list?

In a well-maintained workspace, the expectation is that all dust must be removed to ensure safety and maintain an optimal working environment. Excessive dust can lead to a variety of health problems, including respiratory issues, and can also affect the performance of machinery and equipment. By ensuring that the workspace is free of all dust, organizations not only comply with health and safety regulations but also promote hygiene, enhance employee comfort, and improve overall productivity. This stringent standard is part of maintaining a reliable and efficient operation, where cleanliness directly correlates with equipment reliability and employee health.

Monitoring dust levels (as suggested in one of the other options) is important, but it does not address the proactive stance needed towards maintaining a completely dust-free environment. Thus, focusing on complete removal aligns with best practices in workspace maintenance.
