Face shields protect your face and neck from flying particles and chemical splashes. They don't protect your eyes, however. If you are required to use a face shield while working, you must also wear either safety glasses or chemical-splash-proof goggles. This warning is printed right on the face shield.
What provides more protection? Ear plugs or ear muffs? Each hearing protection device has a Noise Reduction Rating (NRR). This tells how much that particular device will reduce the noise. Earplugs generally have a greater NRR than earmuffs. But neither provides protection unless worn!
Keep making sure that the first "P" in your "PPE" doesn't stand for "Part-time," and that the "S" in your "SOP" doesn't stand for "Shortcut." Many a finger, a job, a mission, even a career, has been cut short by a shortcut. - From the archives of the Summary of Mishaps
