Protect Yourself For The FR4 Dust

Warning – DUST:- If you are going to cut this product yourself ensure that your protect yourself against the dust that will be generated. We highly recommend that your wear a correctly rated half mask respirator. Protective respiratory masks comply to EN149:2001


FFP1 Total inward leakage 22% Filtering Efficiency 78%

FFP2 Total inward leakage 8% Filtering Efficiency 92%

FFP3 Total inward leakage 2% Filtering Efficiency 98% (N100 Equivalent)

This means that an FFP3 Respirator Mask would filter out at least 98% of the airborne repairable particles, whereas an FFP1 Respirator Mask would filter out at least 78% of the repairable particles. FFP3 Respirator Masks are therefore most efficient respiratory masks in filtering out fine particles including viruses, mould spores & asbestos. Therefore ensure that you purchase a good fitting FFP3 Mask.

Fr4 / Carbon Fiber Dust & Sharp Edges

Fr4, G10, Carbon Fiber and other tough laminates that we sell are cut / milled upon a CNC router or wet saw.  In this process dust is created.  We do our utmost to remove the dust via washing.

Care must be taken when handling these products and you must ensure to protect yourself against dust and any sharp edge, by wearing a suitable respirator / dust mask and gloves.
