For a PPE loto workplace safety setup, the first question isn't just what to buy-it's what will actually get used. If you have a worker who needs full-face respiratory protection, a respirator is the obvious focus. If your floor has exposed oil and diesel fuel hazards, signs do the messaging work. Here's a head-to-head look at the New 3M Safety 7800S-M Medium Full Face Respirator Mask Silicone Industrial PPE and the Industrial Safety Sign Lot Used Oil Diesel Fuel Fire Extinguisher PPE OSHA Shop.
Quick Verdict
The 3M respirator is the pick when a worker needs a full-face silicone mask in size medium. The sign lot is the pick when you need multiple visual reminders for oil, diesel, fire extinguisher, and PPE warnings across a shop or facility.

Product Notes
New 3M Safety 7800S-M Medium Full Face Respirator Mask Silicone Industrial PPE

At $234.88, this 3M Safety respirator is the higher-priced item, and it delivers a full-face mask with a silicone facepiece in size medium. The mask comes new in factory packaging and is made in the United States, so it is ready for a worker who needs full-face coverage for industrial tasks. Choose this when one person needs dependable respiratory protection at a workstation. The trade-off is fit: with a medium size, it won't work for every face, and the box shows pink inventory markings on one side from storage. If you need a fleet of masks or a variety of sizes, this single unit only covers one user.
Industrial Safety Sign Lot Used Oil Diesel Fuel Fire Extinguisher PPE OSHA Shop

For $34.19, this lot spreads a lot of visual reminders across a facility: ten Caution Used Oil signs, nine Diesel Fuel No Smoking Open Flames labels, four Fire Extinguisher directional signs, and one Think Safety First Wear Personal Protective Equipment sign. That mix makes it a natural fit for oilfield operations, machine shops, garages, and warehouses. The whole lot ships as pictured and is described as mixed surplus inventory, so individual pieces may show handling marks; check photos to see the exact condition. This is the pick when you need compliance-style reminders in multiple spots rather than a single piece of gear. Just don't expect it to protect a worker directly-it's signage, not PPE.
Final Choice by Use Case
If a worker needs a full-face respirator now, the 3M Safety 7800S-M is the clear choice. If your workplace needs to mark oil, diesel, fire extinguisher, and PPE zones at a lower price, the Industrial Safety Sign Lot is the better fit.
