Why should scaffolding be set up before placing critical barrier plastics?

Setting up scaffolding before placing critical barrier plastics is essential primarily because it ensures that the scaffolding does not damage the barriers. Critical barrier plastics are integral to maintaining a safe and contained environment, especially in asbestos abatement work. If scaffolding is assembled after the plastics are installed, there is a risk of tearing, puncturing, or otherwise compromising the integrity of these barriers during the setup process.

Therefore, arranging the scaffolding first allows workers to secure the area properly, minimizing any potential harm to the barriers and ensuring that they effectively isolate the work zone. This practice helps maintain safety protocols and ensures that the work environment remains controlled, reducing the risk of asbestos fibers spreading and improving overall project compliance with safety standards.
