What thickness of fire retardant polyethylene sheets is required above-ceiling work areas in containment?

For above-ceiling work areas in containment, a thickness of 6-mil fire retardant polyethylene sheets is required. This specification is based on the need for a durable and reliable barrier that can effectively contain dust and debris while providing a level of fire resistance. The 6-mil thickness is sufficient to maintain structural integrity during operations, preventing breaches that could compromise safety and containment effectiveness. It’s a balance between providing adequate protection and ensuring that the materials used are manageable and cost-effective for the scope of work.

Thinner materials, such as 4-mil polyethylene, may not provide the required robustness for containment in situations where there is a significant risk of tearing or puncturing. Conversely, options like 8-mil or 10-mil sheets, while offering additional protection, can be more cumbersome and costly, making 6-mil a practical choice that meets the necessary safety and performance standards for mold remediation and work in above-ceiling areas.
