What condition must be monitored regarding rain during lead-related work?

Monitoring the condition of rain during lead-related work is crucial for maintaining a safe work environment. It is essential that it must not be about to rain because precipitation can significantly compromise both the safety of the worksite and the effectiveness of lead hazard controls.

Rain can lead to the formation of slippery surfaces, increasing the risk of accidents and injuries. Additionally, water can wash away lead dust or debris that is being worked on or encapsulated, possibly spreading lead contamination beyond the immediate work area. Thus, ensuring that conditions are dry helps maintain an effective barrier against lead exposure, keeping workers safe and compliant with safety regulations.

In light of these concerns, the focus is placed on preventing imminent rain to uphold the integrity of the worksite. This monitoring leads to a safer environment for all personnel involved in lead-related projects.
