What does Level 1 of the exterior barrier system entail?

Level 1 of the exterior barrier system involves using one layer of poly every 6 feet. This approach is designed to provide a basic level of containment for lead dust and debris during renovation or remediation activities. The use of poly sheeting plays a critical role in preventing the spread of hazardous materials outside the work area. By applying a single layer of poly at regular intervals, the system maintains visibility and accessibility while still offering some degree of protection.

This option effectively showcases the minimal yet necessary precautions mandated during operations involving lead, ensuring that workers can perform their tasks safely while minimizing environmental contamination. In the context of lead safety practices, this method is foundational, as it allows for initial containment measures that can later be augmented with additional layers or barriers as needed in more advanced levels of intervention.
