FFP3 Mask - minimum grade required for fossil preparation.

Not all face mask filters are created equal! Lighter duty ones won’t prevent you from inhaling rock dust as the particles can be so small. Typically used in the chemical and pharmaceutical industry, these masks are ideal for keeping you safe.

Please always wear a mask. Silicosis is a lung disease caused by breathing in silica particles (silica is a major component in sand and many rocks), which causes scarring of the lungs. Some fossiliferous limestones set underwater, and if you were to inhale that rock dust, you can imagine where it starts to set!
