A 6-Point Safety Checklist for Contractors: Gloves, Glasses, and Roof Harness

I'm a safety equipment coordinator at an industrial supply company. I've handled 200+ rush orders in six years, including same-day turnarounds for contractors who realized at 7 a.m. that the right gloves weren't on the truck. This is the checklist I use when someone says 'we need it today'—and also when they say 'just send us your standard kit.'

Six points. No theory. Check each one before you send a crew out.

1. Match the Showa gloves to the job, not to the brand

Showa gloves get requested by name a lot. That's fair—the catalog is deep. But the first question isn't 'which model?' It's 'what are you handling?' A crew doing general assembly on a black iron fence has different hands than a worker degreasing engine parts.

For all-around dexterity and breathability, the Showa 381 work gloves are the pair I hand out first. Or rather, the pair I hand out after I ask what the task is. The palm coating grips dry and lightly oily materials without turning your hands into ovens. If the job involves sharp metal, though, you need a different glove.

The most important thing I've learned: a glove only protects you if the worker keeps it on. It took me three years and about 150 orders to understand that specs on the box matter less than comfort on the hand. That's why the 381s get worn—they're breathable, flexible, and don't make people want to take them off.

When I compared a crew using the right Showa cut resistant gloves on a black iron fence install with a crew using worn leather gloves, the difference wasn't a close call. It was an urgent care visit. Black iron fence sections have edges that don't look sharp until they find a finger. Order by the hazard, not by the model name.

2. Read the cut-resistance label like it matters

Showa cut resistant gloves are not one product. They're a range, and the range exists for a reason. Per ANSI/ISEA 105-2019, cut resistance is rated A1 through A9. A warehouse worker opening boxes may be fine at a lower level. A metal fabricator handling nail plates, fence rail, or sheet metal should be looking at higher levels. The number on the label is not a marketing suggestion.

I have mixed feelings about the cost jump. On one hand, cut-resistant gloves can cost three times as much as a basic cotton pair. On the other hand, I've seen what a single laceration costs: seven stitches, a missed deadline, and a worker out for a week. The expensive glove is the one that gets the job done without an incident. The cheap one is the one you buy twice, after the first one failed.

If you're ordering for a black iron fence crew, ask the worker who does the cutting. If they say 'we'll be careful,' order the cut-resistant Showa gloves anyway.

3. Don't skip lab safety glasses just because you're not in a lab

The phrase 'lab safety glasses' makes people think of chemistry classrooms. I've been guilty of that, too. But the same ANSI Z87.1-rated lens that handles a splash in a lab also handles a grinding spark, a broken cable, or the little bits of metal that fly when you cut a black iron fence post. At ten to thirty dollars a pair, they are the cheapest insurance on a jobsite. That range is based on what I've seen from distributors in early 2025; verify current pricing for your region.

What I look for before I approve any safety glasses order:

• Z87+ impact rating marked on the frame or lens
• Side shields or wrap-around coverage
• No cracks, deep scratches, or heat damage
• Fit that works under a hard hat or face covering

I've watched a worker say 'I just need to make one cut' and skip the glasses. That one cut is the one that sends a shard into an eye. Put the lab safety glasses on before you pick up the grinder. That's it.

4. How to use safety harness on roof: the 30-second checklist

Now the one that gets the most 'we know this' reactions—and the one that gets skipped most. I'm not a fall-protection engineer. I'd rather say that than pretend otherwise. But I've supplied harnesses to enough roofing and repair crews to know the difference between a harness on a hook and a harness in use.

Per OSHA 29 CFR 1926.501, construction workers at six feet or more above a lower level need fall protection. Verify current requirements at osha.gov. That's the rule. Here's how to use safety harness on roof jobs in the most direct way I know:

1. Inspect the harness first. Check the webbing for cuts, fraying, or sun damage. Check the D-rings, buckles, and grommets. If any part looks questionable, tag it out and don't use it.
2. Put it on the right way. Hold the harness by the dorsal D-ring and give it a shake so the straps untangle. Put your arms through, pull the leg straps up tight, and buckle everything. The dorsal D-ring should sit between your shoulder blades, not at your lower back.
3. Pick the anchor before you get high. Use an anchor rated for 5,000 pounds per worker (OSHA's general requirement) or a certified anchor system. Tie off to a structural beam or engineered anchor point—not to a roof pipe, ladder, guardrail, or piece of flashing.
4. Connect and test. Attach your lanyard or self-retracting lifeline to the dorsal D-ring. Keep the connecting device as short as the work allows. Once you're in position, sit back against the harness to test the system. If it feels wrong, fix it before work starts.
5. Don't extend your reach by adding slack. Adding slack changes a vertical fall into a swing fall, and swing falls hit structures on the way down.

It's a short list. The failure happens when people treat it as optional.

5. Inspect everything before you need it

This is the step that feels too obvious to write down, so it's the step everyone skips. A glove with a torn coating, glasses with scratched lenses, a lanyard with a worn snap hook—all of these are 'fine' until they're not.

Set a five-minute inspection at the start of every day. Not a formal audit, just a hands-on check. The 30 seconds it takes to look at a pair of Showa 381s for cuts in the liner is shorter than the conversation that happens after a glove fails.

If you find something damaged, replace it immediately. Don't put it in the 'maybe' pile. The 'maybe' pile is where incidents come from.

6. Build a 10-minute buffer into every order

This last one isn't about the equipment, it's about the time. In March 2024, a client called at 4 p.m. needing 60 pairs of Showa 381 work gloves for the next morning's assembly. Normal ground shipping would have missed it. We found a courier, paid $180 in rush freight, and got the gloves to the site at 6:30 a.m. The alternative was half a crew standing idle at an hourly rate.

Last quarter alone, we processed 47 rush orders with 95% on-time delivery. The ones that went wrong had one thing in common: someone waited until the last minute to check sizes, stock, or delivery days. A ten-minute buffer—verifying stock, confirming sizes, double-checking the roof anchor point—is worth more than any vendor promise.

Common mistakes I still see

• Ordering one glove model for every task, because it's simpler
• Buying 'lab safety glasses' only for lab work and ignoring them on a construction site
• Attaching a harness to roof flashing or a ladder
• Testing the harness by tugging on it from the ground instead of sitting back into it at height
• Waiting until the order is late to find out the size is backordered

Here's what I do not mean by this checklist: that equipment alone solves safety. Safety is a system. But the system falls apart at the point where someone picks the wrong glove, skips the glasses, or ties off to an unrated anchor. That point is easy to fix.

I'd rather work with a specialist who knows their limits than a generalist who overpromises. Same for suppliers, same for gloves. Know what the job requires, and buy the thing that was built for it. The Showa 381s are my first answer for a lot of general industrial work. They're not my answer for every job. That's the difference between a vendor and an advisor.
