The 3M project safety kit includes safety goggles, respirator and corded reusable earplugs for an all-in-one safety kit. Safety goggles help protect eyes against certain airborne particulates and chemical splash. Corded reusable earplugs provide a 25 dB NRR protection and the N95 respirator is used for non-harmful dusts from sanding, grinding, sawing and insulating particles.
