Hey everyone, if you’ve ever walked through a sheet metal fabrication shop, you know sheet metal presses are the workhorses of the place. We use them every single day at our shop—they’re what turn flat steel, aluminum, and stainless steel into the parts we ship to all kinds of industries, from HVAC to construction to automotive. But let’s be real: these machines are powerful. Like, really powerful. A split second of not paying attention, or skipping a quick safety check, can lead to a bad injury, or worse. Over the years, we’ve learned the hard way that safety procedures aren’t just a bunch of rules written on a wall—they’re the only way we all go home to our families at the end of the shift. Today I’m walking you through exactly what we do on every press, every time, no exceptions. Sheet Metal Fabrication

First off, I need to say this loud and clear: training is non-negotiable. You can’t just tell someone, “Here’s the press, run it.” We don’t let anyone near our 60-ton and 110-ton presses (our two most common models) until they’ve gone through 40 hours of hands-on training with a senior operator, passed a written test, and shadowed three full shifts of live runs. New folks always start with the smallest jobs first, like bending simple brackets, before moving to more complex parts. We do monthly refreshers too—last week we did a mock drill where we practiced hitting the emergency stop in the middle of a cycle, because muscle memory saves lives.
Next up is pre-use checks. We don’t hit the power button until we’ve done a quick walkaround. No cutting corners here. First, we check the emergency stop (E-stop) buttons—they’re bright red, big, and easy to reach, but we still make sure none are cracked or stuck. We press each one to confirm it cuts power instantly; if an E-stop is flimsy, we mark that press “out of service” and flag our maintenance team immediately. Then we check the press brakes—wait, sheet metal presses here are often press brakes, right? The bending ones, yeah. We check the dies: are they aligned properly? No chips, no bent edges? A tiny chip in a die can mark a part permanently, but worse, it can cause a misalignment that makes the press kick back unexpectedly. We also test the clutch and brake system—if the brake doesn’t engage right when you let off the pedal, that’s a problem. Oh, and we never skip checking the safety light curtains. Those are the vertical beams of light on either side of the die area—if anything breaks the beam, the press stops. We wave a small piece of scrap metal through them every single day to confirm they work. Last month we had one that was off by a quarter inch; we fixed it right away, and that probably prevented a near-miss.
When it’s time to actually run the press, personal protective equipment (PPE) is step one, but it’s not just grabbing any gear. We require everyone on the floor near a press (even if you’re not the one running it) to wear steel-toe boots, safety glasses, and hearing protection. Our presses are loud—like, 90 decibels loud, which is enough to cause permanent hearing damage over time. We don’t mess around with earplugs or earmuffs here; everyone has their assigned pair, and we do random checks to make sure they’re actually wearing them, not shoving them in their pocket. For the operator, there’s extra PPE: cut-resistant gloves. Wait, but here’s a rule—we take those gloves off when we’re loading or unloading parts. Gloves can catch on sharp sheet metal edges, and before you know it, your hand’s stuck. That’s a big one we had to learn: gloves for handling sharp metal outside the press, no gloves while the press is running or when you’re reaching into the die area. Also, no loose jewelry—rings, necklaces, dangling earrings. I once had a kid on the team wear a chain that caught on a press handle; he got a small burn, and we’ve banned all necklaces on the floor since. Hair ties too—long hair has to be pulled back tight and tucked under a hard hat.
Operating procedures during runs are where focus has to be 100%. No multitasking, no checking your phone, no chatting so much that you lose track of the cycle. We have a rule: only one person at the press when it’s running. No standing next to the operator, no helping hold a part while it’s bending—all part loading is done from the side, using the press’s own hold-downs or prying bars if needed. We also use two-hand control whenever possible, especially for big parts. That means you have to press both left and right pedals at the same time to start the cycle. It forces you to keep both hands away from the die area, which is genius. We never, ever reach over the press to adjust a part mid-cycle—wait, we never adjust parts while the press is on. If we need to tweak a bend, we hit the E-stop, turn the power off, and wait for the ram to come all the way down before reaching in. No exceptions. Last year a guy tried to adjust a small part mid-cycle and his glove caught on the die; he lost a fingertip. That’s the kind of stuff that sticks with everyone, so we don’t even joke about it anymore.
Lockout/Tagout (LOTO) is another one we don’t mess with. LOTO is what you do when you need to work on the press—changing dies, fixing a leak, cleaning. The rule is: if you’re going anywhere near the moving parts when the power is on, you lock the power disconnect, tag it with your name, and only you hold the key. No one else can turn that power on until you’re done and remove your lock. We had a scare a couple years back where a maintenance guy was fixing a press and a coworker accidentally tapped the wrong button and turned the power on. Luckily he was just reaching in, not doing something that required moving parts, but that’s why LOTO is non-negotiable. We do quarterly LOTO audits, checking every press to make sure the disconnects are clearly labeled, the locks are working, and no one is cutting tags or removing locks that aren’t theirs.
Also, housekeeping. This sounds basic, but it’s huge for safety. We don’t leave scrap metal, tools, or loose parts on the floor around a press. Someone could trip, fall into the machine, or knock a tool into the controls. At the end of every shift, our team sweeps up all metal shavings, puts away any unused dies, and checks that all controls are in the off position. We’ve had spills of hydraulic fluid before—those are slippery, so we clean them up right away, not later. No one gets to go home until their area is tidy.
Wait, what about when something goes wrong? Everyone on our team knows the E-stop is our first move, always. No matter what—if the press is acting weird, if a part is misaligned, if someone’s hand is even close to the die—you hit that red button. Hitting E-stop is never a bad call; it’s better to stop and figure it out than to risk injury. We also have a clear chain of command: if you have an issue, tell your supervisor right away, don’t try to fix it yourself. Our supervisors do a walkthrough every hour on the shop floor, checking all presses, so there’s always someone there if you need help.

I know this all sounds like a lot, but it’s just part of how we do business. We’re a sheet metal fabrication supplier, and our reputation isn’t just for making good parts—it’s for keeping our team safe and making sure every part that leaves our shop is made by people who got home to their families. If you need custom sheet metal parts, brackets, enclosures, whatever, we have the experience and the systems to get the job done right, and safe.
