A Safety Buyer's Checklist: Howard Leight Earplugs, Bulwark Coveralls, and Field Walkthrough Basics

If you're the person who ends up buying safety gear for a crew, this checklist is for you. It's not a full safety program. It's the list I wish someone had handed me in 2018. I've been handling PPE orders and site walks for about six years, and I've made enough documented mistakes to fill a small binder—eleven significant ones, totaling roughly $4,800 in wasted budget. This is the plain checklist that came out of those mistakes.

Who This Is For

This is for small-to-mid-size operations without a full-time safety department. You may be a superintendent, an office manager, or the person who gets 'the safety stuff' added to your week. It's written from a buyer/user perspective, not an acoustics engineering perspective. There are things I can verify with my own eyes, and there are things I'd rather leave to a specialist.

The Checklist

Step 1: Know the noise problem before you buy earplugs

Don't let a sales rep talk you into 'max protection' as the default. I did that once. The result was a crew wearing Howard Leight MAX-1 earplugs NRR 33 where the noise level didn't require that much attenuation, and some workers started removing them because they couldn't hear each other. NRR is a lab number, not a guarantee.

OSHA's hearing conservation threshold is an 8-hour time-weighted average of 85 dBA. That's from 29 CFR 1910.95, and it's still the line I use as of early 2025. If you don't know your exposure levels, get a sound survey done. For most of our work, Howard Leight MAX-1 earplugs NRR 33 are the standard. But we chose them after looking at the work tasks, not before.

If you're searching for Honeywell earplugs Howard Leight, that's the line we use through our distributor. I like that the ordering is simple. 'Simple to order' and 'correct for the job' are two different things, though.

Step 2: Train fit, then check fit

Most earplug problems are fit problems. I'll never forget watching a new guy push a MAX-1 into his ear like it was an in-ear headphone. He never rolled it down. It was sitting in his ear canal, doing maybe 10% of what it should do. He had no idea.

People think the best earplug is the one with the highest NRR. Actually, the best earplug is the one that fits. We do a two-minute refresher with every new hire: roll the foam into a small crease-free cylinder, reach over your head to pull the ear back, insert, and hold until it expands. It sounds simple. It's not intuitive.

Honestly, I'm not sure why some crew members still fight with foam earplugs after training. My best guess is they're rushing and don't want to look silly. If someone has insight, I'd love to hear it.

Step 3: Verify coverall ratings before you buy

The most expensive mistake I made was with clothing, not earplugs. I ordered Bulwark coveralls because a trusted rep recommended them. Good product, wrong rating for the job. It cost me about $1,100 in unused inventory and a three-week delay for a replacement order.

Now I treat every coverall order like a technical purchase. The label has to show the rating. The datasheet has to match the task. If the listing says 'coveralls' and nothing else, I call the supplier. If they can't tell me the rating, I don't order.

Bulwark coveralls are still a common pick for us, but the brand isn't the spec.

Step 4: Walk the perimeter and inspect that black metal fence

This sounds unrelated to PPE. It's not. Every serious audit I've been through includes facility access. Last spring, I found a section of the black metal fence around our equipment yard had been pushed outward. It was barely noticeable from the parking lot. A person could have walked onto the yard without passing the sign-in station.

So glad I walked the perimeter that morning. I almost skipped it because the fence 'looked fine.' We fixed it before the auditor arrived.

Add fence lines, gates, and locks to the same monthly check where you look at exit signs and fire extinguishers. It's a five-minute walk with a camera. The fence phrase is always on my checklist: 'black metal fence: no gaps, no leaning posts, locks work.'

Step 5: Know how to replace smoke detector battery on a schedule

This is the other small item that always shows up in audits. I'll be straight with you: in my first year, I replaced smoke detector batteries only when a unit started chirping. That's backwards. When it chirps, the battery is already low, and if nobody heard it for a few days, you have no idea how long the detector ran without backup power.

If you've ever wondered how to replace smoke detector battery, it's a simple procedure: twist or pull the detector off its base, open the battery compartment, swap in a fresh 9V, reattach it, and press the test button until the beep sounds. The hard part isn't the task. The hard part is doing it before the chirp.

We replace batteries twice a year, in April and October, on the same schedule as daylight-saving time. That's how we catch it before it becomes a problem.

Step 6: Use a simple pre-check list

I keep a spreadsheet with three columns: item, date, verified. It's not fancy. It catches the things that fall through the cracks. Our list currently has 14 line items, and in the past 18 months it's caught 47 potential errors—wrong product numbers, missing battery dates, a fence repair that never got approved, and two orders with substituted brands that didn't meet the spec.

Granted, this takes a little time. But it saves more time than it costs. The list doesn't need to be pretty. It just needs to exist and get used.

Step 7: Know when to call a specialist

This is the step I still have to remind myself of. I can order Howard Leight hearing protection and I can check basic PPE. I'm not an industrial hygienist. When we needed a real noise survey, I spent a week messing with a phone app before I hired a consultant. The report was worth every dollar.

The vendor who told me 'this isn't our strength—here's a specialist who does it better' earned my trust for everything else. I'd rather work with someone who knows their limits than a generalist who promises everything.

Notes and Common Mistakes

A few things I'd tell myself in 2018:

• Don't buy max NRR for everyone. Match the protection to the task.
• Don't assume workers know how to fit foam earplugs. Show them. Watch them do it.
• Don't order coveralls before checking the required rating. The brand name is not a spec.
• Don't leave the black metal fence out of the walk. A gap in the perimeter is a safety gap.
• Don't wait for smoke detector batteries to chirp. Put battery replacement on a calendar.
• Don't let a supplier substitute a product without asking for the updated datasheet.

One caveat: this checklist worked for us because we're a mid-size operation with a fairly predictable calendar. If you're a seasonal crew with big demand spikes or high turnover, the schedule might need to be tighter. Your mileage may vary. But the principle stays the same—check the hazard, verify the product, train the person, and write down what you did.
