In what order should you HEPA vacuum the work area?

The proper order to HEPA vacuum the work area is from top to bottom. This approach is essential in lead abatement and other cleaning processes because it helps to prevent the redistribution of contaminants. Starting at the top allows any dust or debris to fall to lower surfaces, ensuring that when you vacuum these lower areas subsequently, you are capturing the mess created from above.

Beginning at the highest points—such as ceilings, shelves, or high walls—ensures that any lead dust or particles are collected effectively before they can settle on already cleaned areas. This method maximizes the efficiency of the cleaning process and minimizes the risk of lead exposure in the environment. Following this sequence effectively contributes to a safer and cleaner work environment, especially during lead abatement where the potential for exposure to harmful materials is significant.
