A respirator mask is an essential piece of safety equipment that we insist on all course participants having one with them when they attend a workshop course.
It will protect you from dust particles when using certain tools and materials.
There are various manufacturers, but we tend to work with a reusable half mask, like the 3M Half Face Mask Respirator 6000 Series, or similar in combination with vapour and particulate protection, such as the 6099 cartridge.
You can find details of the 3M range of respirators here.
You can watch a video here on how to safely fit your respirator.
