When can pressure treated wood be used in the shop?

Pressure-treated wood is generally not suitable for use in a shop environment, especially when it comes to indoor projects, due to the chemicals used in its treatment process. These chemicals, typically meant to enhance the wood's resistance to rot and insects, can be harmful when inhaled or when they come into contact with skin. As a result, using pressure-treated wood indoors poses potential health risks to those working in the area, making it advisable to avoid its use entirely in a controlled shop environment.

While there are applications for pressure-treated wood, such as outdoor projects where exposure to moisture and insects is common, the inherent risks associated with its indoor use lead to the conclusion that it should never be used in the shop setting. This understanding is crucial in maintaining a safe and healthy workspace for all users.
