Woodworking is an incredibly rewarding pursuit. Above most other hobbies, both health and safety are absolutely key. Workshops are filled with potentially dangerous tools. They can also kick out large volumes of sawdust.
Perhaps you might feel that wearing safety goggles and a mask is adequate but it’s not. Dust can work its way through some masks and it also tends to linger in the air for a long time. The best way to prevent dust from coming in is to invest in a reliable dust collector as a tool of the most experienced craftsmen.
