How many layers of poly are needed when using chemical strippers?

When using chemical strippers, the requirement for two layers of poly is based on the need for effective containment and protection. Two layers of poly help to ensure that any hazardous materials or potentially harmful chemicals that are removed during the stripping process are adequately contained. This minimizes the risk of contaminants escaping into the surrounding environment, thereby enhancing safety for both workers and the areas surrounding the worksite.

Additionally, having two layers of poly provides a backup in case the first layer becomes compromised. This layered approach is a common practice in the handling of hazardous materials and ensures that the area remains safe and that proper environmental safety protocols are adhered to during the application of chemical strippers. The requirement for multiple layers reflects an understanding of the precautionary measures necessary when working with chemical strippers, which can be volatile and potentially harmful if not managed properly.
